A QUESTION OF CHARACTER IN THE MOVIE "DUEL UNDER THE PLANE TREE"

This article analyzes the special characteristics of the film "Duel under the Plane Tree" by screenwriter Riksivoy Mukhammadjanov, which has a significant role in the development of the comedy genre in Uzbek cinema, and also examines the artistic and ideological features of the film, the achievements of its creative components and the significance in our modern cinema.

SEASONAL DYNAMICS OF THE MAIN MARKERS OF STRESS IN PLATANUS ORIENTALIS LEAVES IN THE CONDITIONS OF THE URBAN ENVIRONMENT SEMIARIDE ZONE

Today, the resistance of plants to stress is one of the most basic and important problems. Plants are sufficiently resistant to oxidative disorders that occur with sudden changes in the physiological state of the organism. This suggests that plant cells have an antioxidant system that can protect against oxygen radicals and singlet oxygen. They are different from animals that have an immune system. The article describes the state of the antioxidant system of the Platanus orientalis tree in the urban semiarid zone from June to September. In addition to the impact of climatic conditions, the impact of an additional man-made stress factor in the form of a highway was also assessed. It is known that all living organisms have the ability to adapt to biotic and abiotic environmental factors and protect themselves from adverse conditions. The article describes the state of the antioxidant system of the plane tree plant growing in Uzbekistan in the summer. During the season, the amount of malondialdehyde and proline was studied.

Sorptive removal of ibuprofen from water by natural porous biochar derived from recyclable plane tree leaf waste

To remove ibuprofen (IBP) in water efficiently and economically, plane tree leaf-derived biochar (P-BC) as a new adsorbent was prepared via pyrolysis at 600 °C. Textural characterizations of P-BC exhibited a porous structure and abundant hydroxyl groups. The results of FTIR and XPS indicated that -OH functional groups played a key role in the adsorption process. Batch adsorption studies were carried out at pH values of 2 to 8, adsorbent dosage of 0.1 to 2.0 g/L and initial concentrations of 500 to 5000 μg/L. Adsorption results showed that P-BC (1.0 g/L) could remove as much as 96.34% of ibuprofen (2000 μg/L) in a strong acidic environment (i.e. pH 2). The adsorption of ibuprofen by P-BC was found to be more consistent with the pseudo-second order kinetic model and Langmuir isothermal model with higher correlation coefficients of 0.999 and 0.996, respectively. Its maximum adsorption capacity was up to 10,410 μg/g. A mechanism analysis demonstrated that the -OH functional groups on the surface of P-BC could form hydrogen bonds with IBP as donors and acceptors, respectively. It played a predominant role in removing IBP. In particular the fabricated P-BC is an effective and recyclable sorbent and its efficiency in removing ibuprofen can still reach more than 70% after five regenerations. The total production cost of P-BC is 4.05 USD / kg, which is equivalent to the treatment cost of only 0.004 USD/L wastewater. The results revealed that P-BC is an environment-friendly, low-cost and efficient adsorbent for removing IBP from water.

Environmental decision support system for Plane trees failure prediction: A comparison of multi‐layer perceptron and random forest modeling approaches

AbstractTree risk is the likelihood of property damage or personal injury from a potentially hazardous tree in cities. We aimed to compare multilayer perceptron (MLP) and random forest (RF) model techniques to predict Plane trees failure hazard in urban areas. In this research, 500 Plane trees in different urban structures were selected, and 12 variables were measured for target trees prediction as model independent variables. Tree failure hazard (tree fails along next 3 yr) was modeled by two machine learning techniques: MLP and RF. The RF model represents the higher accuracy in training (100%), test (94.4%), and all data sets (98.4%). The results of variable importance calculation of designed RF model revealed that wind‐protected aspects, soil depth, length of cracks and cavities, and internal decay are the most important variables respectively that influence the classes of Plane tree failure. The urban foresters or designers can easily determine the possibility of Plane trees risk by running the designed graphical user interface and entering 12 variables of Plane tree. As a result, it will help foresters and urban area managers to make better decisions and predict the proper time to decrease harm from Plane tree failure.

«Восточные» наброски М.Ю. Лермонтова из «Записной книжки, подаренной В.Ф. Одоевским»: история текста и смысловая архитектоника

The aim and objectives of the study are determined by the need to reconstruct an authentic text, whose reception allows clarifying the specifics of Lermontov’s ethnographism and psychologism when creating an artistic image in the “Oriental” sketches “Correcting with a Lily Hand ...” and “On a Cloak Under the Shade of a Plane Tree ...”. The specific toolkit for analysis is the use of the primary source: its description and the compilation of a diplomatic transcription. The theoretical and methodological basis is textual, structural-semantic and cultural-historical approaches to the study of a literary text. All publications of texts are sequentially considered: from the first edition by A.A. Kraevsky in Otechestvennye zapista to the academic edition of 2014. As a result of the study, the authors have found that in all editions of the sketches there are discrepancies with autographs. In a number of cases, editorial corrections were justified, since they were associated with bringing the text to the linguistic standard, deviations from which Lermontov allowed due to the draft nature of the texts. The authors explain the swap of verses, the reasons for correcting proper names in Lermontov’s autographs; reveal incorrect publishing corrections that weaken the artistic impact of the text and belittle the skill of Lermontov as a psychologist and his ethnographic awareness; outline the role of exotic Oriental vocabulary and its changes: to recreate the Oriental color as conditioned by socio-cultural and psychological aspects. The authors propose a reasoned reconstruction of the authentic text of the sketches, which are presented as a single concept. The authors prove that the sketches are characterized by stylistic unity and are in line with Lermontov’s “Oriental” text as a whole. Their structural and conceptual study confirms that Lermontov’s works of 1841 are characterized by a synthesis of romantic and realistic principles of depiction with the priority of the realistic method. The authors draw conclusions about the aesthetic principles of Lermontov’s depiction of an “Oriental” person - about the peculiarities of characters’ individualization and typology, and determine ways of explicating the Oriental flavor. The authors show that Lermontov’s ethnographic observations concentrate on the “Oriental” topos and are characterized by accuracy, deep immersion in Caucasian ethnopsychology. The systematic analysis and the results of the reconstruction of the sketches “Correcting with a Lily Hand ...” and “On a Cloak Under the Shade of a Plane Tree ...” give grounds to speak about their importance for drawing up an integral idea of Lermontov’s creative process, including due to the small number of his draft autographs. The authors declare no conflicts of interests.

PaNAC089 is a membrane-tethered transcription factor (MTTF) that modulates flowering, chlorophyll breakdown and trichome initiation.

Flowering and senescence are essential developmental stages of green plants, which are governed by complex molecular regulatory networks. However, the connection between flowering regulation and senescence regulation in London plane tree (Platanus acerifolia ) remains unknown. In this study, we identified a gene PaNAC089 from London plane tree, which encodes a membrane-tethered transcription factor (MTTF) belonging to the NAC (NAM, ATAF1/2, CUC2) transcription factor family. We investigated the functions of PaNAC089 in the regulation of flowering and senescence through the analysis of expression profiles and transgenic phenotypes. Heterologous overexpression of ΔPaNAC089 delayed flowering and inhibited chlorophyll breakdown to produce dark green rosette leaves in Arabidopsis . In addition, the trichome density of rosette leaves was decreased in transgenic lines. In ΔPaNAC089 overexpression plants, a series of functional genes with inhibited expression were identified by quantitative real-time polymerase chain reaction (qRT-PCR), including genes that regulate flowering, chlorophyll decomposition, and trichome initiation. Furthermore, Δ PaNAC089 directly binds to the promoter of CONSTANS (CO ) and NON-YELLOWING2 (NYE2 ) in the yeast one-hybrid assay. Consistent with this, luciferase (LUC) transient expression assays also showed that Δ PaNAC089 could inhibit the activity of NYE2 . To summarise, our data suggests that PaNAC089 is an MTTF that modulates flowering, chlorophyll breakdown and trichome initiation.

Plasma T3 (Triiodothyronine) and T4 (Thyroxine) Hormone Levels As Reference Values In Rehabilitated Healthy Gray Herons (Ardea cinerea)

In the rehabilitation of wild birds, determining the release criteria is very important for the survival of the animal after its release to the nature. When determining these criteria, the clinical examinations and clinical data of the animals should be evaluated. Therefore, reference laboratory values play a vital role in determining release to nature. In this study, 15 (fifteen) adults and healty Gray heron (Ardea cinerea) were brought to the 'Kafkas University, Wild Animal Protection, Rescue, Rehabilitation Application and Research Center' clinic in May 2016, because their nests were destroyed as a result of the overturning of the plane tree in Iğdır province, and they did not leave their surroundings, were rehabilitated. Birds were kept in bird care rooms specially designed for their species in the rehabilitation center. The birds were taken blood 4 days after being rehabilitated and then released into the nature. Plasma T3 and T4 hormone levels in birds were determined as a result of the analysis of blood samples. It was concluded that the differences in plasma T3 and T4 hormone levels obtained from a total of 15 birds were due to the increasing physiological and metabolic needs during the captivity period in center.

Optimization of Ecosystem Services of Shanghai Urban–Suburban Street Trees Based on Low-Carbon Targets

Road traffic carbon emissions are an important cause of global warming, and street trees play an important role in regulating road carbon emissions. During urbanization, major differences in the planting management modes and growth status of the street trees in urban–suburban gradient may exist, leading to significant differences in the low-carbon values of the street trees in urban–suburban gradient. Based on this, this study took two typical urban–suburban gradient zones in Shanghai as an example to analyze the changes in the characteristics of street tree species, planting density, tree sizes, and low-carbon contribution with urban and rural changes, and proposed strategies for optimizing the low-carbon contribution of urban street trees. The results showed that, from the inner ring to the outer ring and the suburban ring, the proportion of London plane tree gradually changed from 82% to 11%, and the proportion of the camphor tree gradually changed from 9% to 70%; the average DBH of the trees gradually decreased from 28.81 to 23.74 cm. The number of plantings per unit road length gradually increased, and the number of plantings per unit area gradually decreased; therefore, the average low-carbon contribution of urban–suburban street trees is not significant, but the low-carbon contribution of upper street trees per unit area is higher, and suburban unit street trees have a higher low-carbon contribution. Finally, this article proposes different optimization strategies for future urban micro-renewal and suburban new-city construction.

A PILOT STUDY OF SENSITIZATION TO PLANE TREE POLLEN IN SOFIA, BULGARIA

Purpose: Platanus pollen is a serious cause of asthma, allergic rhinitis and conjunctivitis in many European countries. The aim of the present pilot study is to investigate the sensitization to 3 different plane tree species in a group of patients with pollinosis. Materials and methods: 21 patients were surveyed - 11 men and 10 women. A skin prick test was performed with a set of allergens: Grass pollen mix; Betulaceae pollen mix; Platanusorientalis; Platanusacerifolia; Platanusoccidentalis. Results: 95% of patients are sensitized to grass pollen, with moderate positive skin reactions predominating. 86% have a co-sensitization to tree pollens also, particularly to the birch tree family. Only 3 (14%) of the studied patients showed slight positive skin tests to the studied plane tree allergens, with no significant difference in sensitization to studied Platanus species (p>0,05). Conclusion: At present, the sensitization to different Platanus species is not comparable to that of grass or birch pollen. However, it will be necessary to conduct new long-term, large-scale studies to prove whether Platanus pose a real threat to people in urban areas. The results of this interdisciplinary study are important both for clinical allergologists and for landscape architects and ecologists involved in the planning and management of urban green infrastructure.

First report of Pseudocercospora platanigena in Australia

A distinct black leafspot with fungal growth was found on Platanus orientalis ‘Digitata’ (cut-leaf oriental plane tree) in northern Sydney, New South Wales, Australia, in February 2019. Morphological characteristics, internal transcribed spacer sequencing and phylogenetic analysis of the associated fungus identified it as Pseudocercospora platanigena (= Stigmina platani). This pathogen has previously been reported from Pl. orientalis (oriental plane tree) in Europe and Asia and more recently from Pl. orientalis ‘Digitata’ in New Zealand. This is the first report of Ps. platanigena in Australia. Pseudocercospora platanigena is now common on Pl. orientalis ‘Digitata’ throughout Sydney and has been found as far north as Dorrigo in northern New South Wales and west to the Blue Mountains. Pseudocercospora platanigena has not been observed on Pl. orientalis other than the cultivar ‘Digitata’, nor on the more commonly planted London plane tree (Pl. x acerifolia) in Australia. It has not been found in other states in Australia.

Allergenic potential of Platanus L. species in urban environment

Abstract The species of the genus Platanus L. are widely used in urban green infrastructure in Bulgaria and abroad, but are proven to be a serious source of allergen pollen emissions. The number of people, affected by pollinosis, is increasing every year and this affects the world economy and health of the population in a high level. The pollen of the plane tree is light, very small and spreads anemophilically. This is one of the genera that produce the largest amount of pollen per inflorescence. This makes Platanus a tree of a high allergy potential that has the tendence to get higher in time, because of its increasing use in urban green spaces. The aim of this study is to collect data for allergy potential of the three species of plane tree in some of the European countries, where the allergy is a significant problem, and to compare the sensitization of patients to its pollen in Bulgaria.

The Bernardi Formula for Nontransitive Deformations of the Braid Arrangement

Bernardi has given a general formula for the number of regions of a deformation of the braid arrangement as a signed sum over boxed trees. We prove that each set of boxed trees which share an underlying (rooted labeled plane) tree contributes 0 or $\pm 1$ to this sum, and we give an algorithm for computing this value. For Ish-type arrangements, we further construct a sign-reversing involution which reduces Bernardi's signed sum to the enumeration of a set of (rooted labeled plane) trees. We conclude by explicitly enumerating the trees corresponding to the regions of Ish-type arrangements which are nested, recovering their known counting formula.

Management of patients with seasonal allergic rhinitis: Diagnostic consideration of sensitization to non-frequent pollen allergens.

BackgroundDiagnosis of pollen allergies is mainly based on test allergens for skin prick testing. In the minimum battery of test inhalant allergens recommended by the Global Allergy and Asthma European Network 10 pollen allergens are included. Complementary other pollen allergens may need to be considered; however, respective awareness may not always be granted. Furthermore, at least in Germany, the situation may be even more complicated by the fact that test allergens need regulatory approval. A decline in commercially available test allergens may result in a diagnostic gap regarding patients with non‐frequent allergies. How many patients with non‐frequent pollen allergies would be affected by this gap? The data presented here partly answer this question.MethodsThe study consisted of a descriptive and an analytical part. In the descriptive part, sensitization to frequent pollen allergens (alder, hazel, birch, sweet grasses; according to the German Therapy Allergen Ordinance) and to respective non‐frequent pollen allergens (cypress, Japanese cedar, ash, plane tree, olive, Bermuda grass, wall pellitory, plantain, goosefoot, mugwort, ragweed, and saltwort) was measured in adult patients with physician‐diagnosed allergic rhinitis from two German federal states, namely North‐Rhine Westphalia (n = 360) and Bavaria (n = 339), using skin prick testing and/or ISAC technology. Furthermore, respective regional pollen data were assessed. In the analytical part, sensitization data were correlated with each other and with anamnestic data on symptom periods.ResultsSensitization to frequent pollen allergens ranged from 45% (sIgE to Aln g 1/Alder, NRW) to 72% (prick test reactivity to birch, NRW). Sensitization to non‐frequent pollen allergens ranged from 0% (sIgE to Amb a 1/ragweed, NRW) to 41% (prick test reactivity to olive, Bavaria). Sensitization data partly correlated with each other and in connection with symptom periods showed a partly similar seasonal pattern as pollen data.ConclusionsSensitization to non‐frequent pollen allergens have to be considered when examining patients with respective seasonal symptoms, and test (and respective therapy) allergens for non‐frequent pollen allergies need to be available. Further prerequisites for adequate patient management would be a nationwide pollen monitoring system giving continuous pollen data and a systematic sensitization monitoring at patient level.

A Class II TCP Transcription Factor PaTCP4 from Platanus acerifolia Regulates Trichome Formation in Arabidopsis.

London plane tree is widely grown as a landscaping and street tree, but the release of its trichomes creates a serious air-borne pollution problem. Identifying the key genes that regulate the development of trichomes is, therefore, an important tool for the molecular breeding of Platanus acerifolia. In this study, a sequence homologous with the Arabidopsis Class II TCP subfamily was identified from London plane, and named PaTCP4. The expression of PaTCP4 was detected in various organs of London plane trees, significantly in the trichomes. Overexpression of PaTCP4 in Arabidopsis reduced the trichome density on the first pair of true leaves, and atypical 5-branched trichomes were also detected on those leaves. The expression of endogenous AtCPC and AtTCL2 was significantly increased in PaTCP4 transgenic lines, and was associated with a decrease in the expression of endogenous AtGL2. Furthermore, the expression of endogenous AtGL3 was significantly increased. In addition, the protein product of PaTCP4 was shown to directly activate AtCPC, AtTCL2, AtGL3, AtGIS, PaGIS, and PaGL3 in yeast one-hybrid assays and in the dual-luciferase reporter system. Taken together, these results identify a role for PaTCP4 in trichome initiation and branching in Arabidopsis. Thus, PaTCP4 represents a strong candidate gene for regulating the development of trichomes in London plane trees.

Herbal product use patterns and possible herb-drug interactions among older adults in Turkey

BackgroundTraditional and Complementary medicine use is on the increase universally. In this descriptive study, the aim is to evaluate the frequency and determinants of herbal product use, as well as determine possible drug-herb interactions among older individuals who live in rural and urban areas. MethodsThe study was carried out with individuals 65 years or older in one urban and five rural neighborhoods in Bursa, Turkey. The data was collected during face-to-face interviews using a questionnaire comprising 43 questions. The participants were asked about the drugs and herb/herbal products they use and then the possible drug-herb interactions were evaluated using Micromedex®. ResultsAmong the participants, 82.2 % reported using at least one drug regularly, and 18.3 % used at least one herb/herbal product in the past year (rural 26.1 %, urban 13.4 %). Most commonly used herb/herbal products were plane tree leaves and black cumin. Herbal product use was seen more among those experiencing difficulties accessing health care and living alone. Among those using drug and herb/herbal products concurrently, the possible drug-herb interaction rate was 7.5 %. ConclusionsPhysicians providing health care services to geriatric populations should inquire about usage of drugs and herbs. Conventional medicine should be made accessible to every older adult, and it should be ensured that they do not have to resort to complementary therapies that could harm their health.

Urban Tree Growth Characteristics of Four Common Species in South Germany

Urban trees are important, green features of cities. However, knowledge of the size development of frequently planted tree species, which is the basis for modeling environmental benefits of urban trees, is mostly limited. Within this study, allometric relationships for tree structures like tree height, crown parameters, and leaf area were developed for 4 common urban tree species in South Germany (horse chestnut [Aesculus hippocastanum], small-leaved lime [Tilia cordata], black locust [Robinia pseudoacacia], and plane tree [Platanus × hispanica]). Growth and size differences between different tree species, cities, and planting sites (street, park, square) were analyzed. Moreover, the above- and belowground growing conditions were compared and their influences on growth analyzed. Marked differences in the structural development between species were found, mostly due to their species characteristics. Fast growing species (e.g., R. pseudoacacia) also showed fastest development of the tree structures compared to other species. Differences between cities were minor, especially for trees younger than 100 years, whereas the variation of growing conditions within cities strongly influenced their growth. Park trees mostly had greater tree structures compared to trees at other growing sites, though this was also species-dependent. Above- and belowground conditions varied between species, cities, and sites (street, park, square), with obstacles (trees, buildings) south of the trees having a negative influence on crown growth. These patterns can be helpful for better planning of green features in cities. They provide a basis for urban tree management based on the growing space requirements of tree species and their ecosystem service provision.

Delay-Aware Control Plane Virtual Topology Design of Software Defined-Elastic Optical Network

An upper bound on the delay in the control channels is necessary as control state inconsistency significantly degrades the performance of a logically-centralized and physically-distributed control plane. Statistically multiplexing control traffic with the data traffic (in-fiber in-band) or reserving a low-rate control channel does not ensure QoS guarantees in terms of delay specially if the network is congested. Therefore, control traffic must be viewed and treated differently from data traffic. This article presents ac MILP and a heuristic to design distributed SDN-based in-fiber out-of-band control plane for elastic optical network (EON). The objective is to minimize the number of controllers while reserving resources for the control traffic to ensure that delay in the control channel is bounded. The designed inter-controller virtual tree topology avoids control traffic replication. For better resource utilization it requires OEO conversion at every controller node for grooming control traffic and this incurs queuing delay at each controller node. The design takes into account queuing delay along with transmission and propagation delay in control plane links and maintains the total delay within a specified bound. To the best of our knowledge, this is the first work to analyze queuing delay along with transmission and propagation delay in inter-controller links of the control plane. We further present a MILP to make this virtual control plane tree topology survivable against single link failure by utilizing the concept of fundamental cycles. The numerical results show that our proposed control plane design performs better than existing control plane designs where control traffic is statistically multiplexed with data traffic in terms of delay in the control plane and blocking probability in the data plane.

Non-specific lipid-transfer proteins: Allergen structure and function, cross-reactivity, sensitization, and epidemiology.

BackgroundDiscovered and described 40 years ago, non‐specific lipid transfer proteins (nsLTP) are present in many plant species and play an important role protecting plants from stressors such as heat or drought. In the last 20 years, sensitization to nsLTP and consequent reactions to plant foods has become an increasing concern.AimThe aim of this paper is to review the evidence for the structure and function of nsLTP allergens, and cross‐reactivity, sensitization, and epidemiology of nsLTP allergy.Materials and MethodsA Task Force, supported by the European Academy of Allergy & Clinical Immunology (EAACI), reviewed current evidence and provide a signpost for future research. The search terms for this paper were “Non‐specific Lipid Transfer Proteins”, “LTP syndrome”, “Pru p 3”, “plant food allergy”, “pollen‐food syndrome”.ResultsMost nsLTP allergens have a highly conserved structure stabilised by 4‐disulphide bridges. Studies on the peach nsLTP, Pru p 3, demonstrate that nsLTPs are very cross‐reactive, with the four major IgE epitopes of Pru p 3 being shared by nsLTP from other botanically related fruits. These nsLTP allergens are to varying degrees resistant to heat and digestion, and sensitization may occur through the oral, inhaled or cutaneous routes. In some populations, Pru p 3 is the primary and sole sensitizing allergen, but many are poly‐sensitised both to botanically un‐related nsLTP in foods, and non‐food sources of nsLTP such as Cannabis sativa, Platanus acerifolia, (plane tree), Ambrosia artemisiifolia (ragweed) and Artemisia vulgaris (mugwort). Initially, nsLTP sensitization appeared to be limited to Mediterranean countries, however more recent studies suggest clinically relevant sensitization occurs in North Atlantic regions and also countries in Northern Europe, with nsLTP sensitisation profiles being broadly similar.DiscussionThese robust allergens have the potential to sensitize and provoke symptoms to a large number of plant foods, including those which are raw, cooked or processed. It is unknown why some sensitized individuals develop clinical symptoms to foods whereas others do not, or indeed what other allergens besides Pru p 3 may be primary sensitising allergens. It is clear that these allergens are also relevant in non‐Mediterranean populations and there needs to be more recognition of this.ConclusionNon‐specific LTP allergens, present in a wide variety of plant foods and pollens, are structurally robust and so may be present in both raw and cooked foods. More studies are needed to understand routes of sensitization and the world‐wide prevalence of clinical symptoms associated with sensitization to these complex allergens.

On selecting a fraction of leaves with disjoint neighborhoods in a plane tree

We present a generalization of a combinatorial result by Aggarwal et al. (1989) on a linear-time algorithm that selects a constant fraction of leaves, with pairwise disjoint neighborhoods, from a binary tree embedded in the plane. This result of Aggarwal et al. (1989) is essential to the linear-time framework, which they also introduced, that computes certain Voronoi diagrams of points with a tree structure in linear time. An example is the diagram computed while updating the Voronoi diagram of points after deletion of one site. Our generalization allows that only a fraction of the tree leaves is considered, and it is motivated by research on linear time construction algorithms for Voronoi diagrams of non-point sites. We are given a plane tree T of n leaves, m of which have been marked, and each marked leaf is associated with a neighborhood (a subtree of T ) such that any two topologically consecutive marked leaves have disjoint neighborhoods. We show how to select in linear time a constant fraction of the marked leaves having pairwise disjoint neighborhoods.

Urban allergy review: Allergic rhinitis and asthma with plane tree sensitization (Review).

Respiratory allergies represent a major public health issue in the modern world. Pollens are among the most significant causes of seasonal allergic rhinitis, with pollens of wind-pollinated trees representing an important cause. Members of the Platanaceae family (Platanus acerifolia, Platanus orientalis) are well-recognized sources of allergenic pollens worldwide, due to their high capacity of sensitization and widespread usage as ornamental urban trees. Air pollution, characteristic to all important urban conglomerates in the world and provoked by diesel exhaust gases, industrial and domestic fumes, and biogenic volatile organic compounds represents another major public health issue. Plane trees, along with other species of trees, are one of the main sources of volatile compounds. Recent studies have demonstrated a strong correlation between air pollution and respiratory allergies, with airway chemical compounds intensifying the capacity of sensitization to allergenic pollens. This study presents an overview of the known negative elements on public health of the Platanus family.
