Effects of industrial pollution and ambient air temperature on larval performance and population dynamics of Eriocrania leafminers (Lepidoptera)

Pollution is an integral part of global environmental change, yet the combined and interactive effects of pollution and climate on terrestrial ecosystems remain inadequately understood. This study aims to explore whether pollution alters the impacts of ambient air temperature on the population dynamics of herbivorous insects. Between 1995 and 2005, we studied populations of two closely related moths, Eriocrania semipurpurella and E. sangii, at eight sites located 1 to 64 km from a large copper‑nickel smelter in Monchegorsk, Russia. We found that pollution and temperature influence the performance of Eriocrania larvae mining in the leaves of mountain birch, Betula pubescens var. pumila, through multiple pathways. This is evident from the unconsistent changes observed in larval and frass weight, mine area, and leaf size. We found increases in both leaf quality and larval weight with decreasing pollution levels at both spatial and temporal scales and attributed these to the impact of sulphur dioxide, rather than trace elements (nickel and copper). The quality of birch leaves increased with spring (May) temperatures, enabling Eriocrania larvae to achieve greater weight while consuming less biomass. During the larval growth period (early June to early July), Eriocrania larvae increased their consumption with rising temperatures, presumably to compensate for increased metabolic expenses. Contrary to our expectations, the per capita rate of population change did not correlate with larval weight and did not vary along the pollution gradient. Nevertheless, we detected interactive effects of pollution and climate on the rate of population change. This rate decreased with rising winter temperatures in slightly polluted and unpolluted sites but remained unchanged in heavily polluted sites. We conclude that pollution disrupts mechanisms regulating the natural population dynamics of Eriocrania moths.

Comparative physiological adaptations to industrial pollution stress mediated by melatonin in riparian vegetation and Phyla nodiflora an ornamental plant

This study explores the macro nutritional contents and endogenous melatonin in the structural differences of riparian flora and horticultural ecotype growing in industrially contaminated environments. Water pollution caused by anthropogenic activities poses uncompromising threats to rivers and water sources, resulting in the extinction of many species and the reduction of others to endangered status. Effluents from the industrial hub of Faisalabad are discharged into the Chenab River in Punjab province. As in other parts of the world, effluents from Faisalabad industries pose a great threat to native vegetation in the area. Therefore, this study was designed to verify the presence of industrial pollution. Moreover, the effects of industrial pollution on native vegetation and the survival strategies of adapted species were also assessed. Results showed that several abiotic stresses have been mitigated by endogenous melatonin in herbs and herb-based products. The survival of herbs depends on specific changes to biochemical compounds like melatonin content and vascular structures. Overall, industrial pollution harmed herbs' metabolism and antioxidant activity, although the reactions of specific species to industrial pollution varied. Changes in the concentration of endogenous melatonin metabolism have been identified as promising indicators for industrial pollution biomonitoring. Internal alterations of plants vegetating at various industrially polluted locations contributed significantly to the high level of tolerance of these plants. The typical reaction of all herbs to increased pollution was growth modification in terms of endogenous melatonin content, moisture content, carbohydrates, crude protein, and dry matter. Most of the proximate, melatonin and chlorophyll content were significantly high in indirectly affected vegetation and high in directly affected industrial pollution. Biochemical investigation specifies that in response to industrial pollution four species Calotropis procera, Eclipta alba, Phyla nodiflora (Ornamental plant) and Ranunculus sceleratus increased the primary metabolites like melatonin, carbohydrates, crude protein, crude fibers, and fats.

Industrial Pollution Effects on the Lives of Residents: A Case Study of Korangi Industrial Area

The rapid industrialization in the Korangi Industrial Area has led to increased levels of pollution, posing significant challenges to the lives and livelihoods of the residents. The release of harmful pollutants, such as toxic gases and industrial waste, has raised concerns about the health, environment, and socio-economic well-being of the local population. The present research study aims to explore the extent of pollution, its impact on the health and well-being of individuals, and the associated socio-economic consequences. By examining the case of Korangi Industrial Area, the study seeks to contribute to the understanding of industrial pollution's adverse effects on residents and provide recommendations for mitigating these effects. The present research study employed a quantitative technique. Data was collected through a survey based on five points Likert scale. A stratified random sampling technique was used to select a representative sample of 150 residents from different areas within the Korangi Industrial Area of 2 Km in the surrounding. Data is analysed through SPSS 26 and results are presented in descriptive and inferential statistics. The present research study concludes that industrial pollution in the Korangi Industrial Area has severe detrimental effects on the lives of residents. The high levels of pollution adversely affect their health, well-being, and socio-economic conditions.

Health risk management framework for heavy metals and cyanide in Kwekwe city of Zimbabwe: a mixed-method study protocol

BackgroundAccording to WHO, in 2015, over 35% of ischaemic heart disease, the leading cause of death and disability worldwide, and about 42% of strokes, the second largest contributor to global mortality, could have been prevented by reducing or removing exposure to chemical pollutants. Heavy metal and cyanide pollution are prevalent in developing countries, especially in sub-Saharan Africa where the effects of industrial pollutants are more severe, partly due to poor regulation. In Zimbabwe, the mining industry alone contributed to 25% of occupational conditions and injuries in 2020. Therefore, to mitigate these problems, this study seeks to develop a health risk management framework for heavy metals and cyanide pollution in the industrial city of Kwekwe.MethodsThe convergent parallel mixed-method study design will be utilised. Qualitative and quantitative data will be collected, analysed, and merged in order to inform the development of the risk framework. An analytical cross-sectional survey would be used to determine levels of heavy metals in surface water, soil, and vegetables. Free cyanide will be determined in surface water samples only. The phenomenological qualitative inquiry will be used to investigate health events and risks associated with potentially toxic pollutants (heavy metals and cyanide) to describe or interpret participants' lived experiences. The qualitative and quantitative results will be used to develop and validate the framework to manage identified health risks. For data analysis, statistical analysis will be used in the quantitative study, while thematic analysis will be used in the qualitative study. The study was approved by the University of Venda Ethics Committee (Registration Number FHS/22/PH/05/2306) and the Medical Research Council of Zimbabwe (Approval Number MRCZ/A/2944). All ethical principles will be adhered to throughout the study in accordance with the Helsinki Declaration.DiscussionWhile existing risk management frameworks have significantly contributed to human and environmental health protection, novel and comprehensive frameworks need to be developed to counter the ever-dynamic and evolving risks associated with chemical pollutants. If the management framework is successfully developed, it could offer an opportunity for the prevention and control of potentially toxic elements.

Morphological parameters of hepatocytes in the European mole (Talpa europaea) and herb field mouse (Sylvaemus uralensis) under industrial pollution: Qualitative and quantitative assessment.

Morphological alterations of cells and tissues usually occur in biological organisms exposed to environmental contaminants, thereby acting as a biomarker of environmental pollution, thus, making this study highly pertinent. The effect of industrial pollution on the qualitativeand quantitative morphological parameters of hepatocytes (through histological analysis andcytomorphometry) was studied in two contrasting species of small mammals (Talpa europaea and Sylvaemus uralensis), taking into account the animal age (young and adult groups) and liver concentrations of heavy metals (Cu, Zn, Cd, Pb). Studies were performed in the regions exposed to emissions from two currently operating copper smelters: Middle Ural Copper Smelter (Middle Urals, T. europaea catching area) and Karabash Copper Smelter (Southern Urals, S. uralensis catching area). Seven morphometric parameters of hepatocytes were measured, of which two key parameters were selected by the method of principal components-the cell packing density and nuclear-cytoplasmic ratio (N/C). It was found that cell packing density in T. europaea from the impact zone decreased relative to the background area in young animals. At the same time, the differences in this parameter between the age groups from the background zone were leveled in the impact area of catching. The N/C ratio in T. europaea hepatocytes showed no correlation with either animal age or site of capture (background or impact area). In S. uralensis, both parameters, even taking into account the age, were found to be insensitive to indicate an effect of industrial pollution. Dystrophic changes (tested through histological analysis) in the liver tissue were revealed in all animal groups, but their frequency did not depend on any of the factors (age, zone) as well as the level of accumulation of toxicheavy metals (Cd, Pb). Morphometric parameters of hepatocytes have proved to be more reliable indicators of pollution, compared to the frequency of liver histopathology, due to lower subjectivity in their evaluation.

Recovery of moth and butterfly (Lepidoptera) communities in a polluted region following emission decline.

Environmental pollution is one of the major drivers of the present-day decline in global biodiversity. However, the links between the effects of industrial pollution on insect communities and the underlying species-specific responses remain poorly understood. We explored the spatial pattern in insect communities by analysing 581 samples of moths and butterflies (containing 25,628 individuals of 345 species) collected along a strong pollution gradient in subarctic Russia, and we recorded temporal changes in these communities during the pollution decline that occurred from 1992 to 2006. In the 1990s, the diversity of the Lepidoptera community was positively correlated with the distance from the copper-nickel smelter at Monchegorsk. The overall abundance of Lepidoptera did not change along the pollution gradient, although the abundance of many species decreased with increasing pollution. The responses of each individual species to pollution were associated with its life history traits. The abundances of monophagous species that fed inside live plant tissues and hibernated as imagoes or pupae were not affected by pollution, whereas the abundances of oligophagous and polyphagous species that fed externally on plants and hibernated as larvae generally declined near the smelter. Substantial decreases in aerial emissions from the smelter between 1992 and 2006 resulted in an increase in the diversity of moths and butterflies in severely polluted habitats, whereas their overall abundance did not change. This recovery of the Lepidoptera community occurred due to the reappearance of rare species that had been previously extirpated by pollution and was observed despite the lack of any signs of recovery of the vegetation in the heavily polluted sites. We conclude that the recovery trajectories of insect communities following emission control can be predicted from studies of their changes along spatial pollution gradients by using space-for-time substitution.

Community Perspectives and Environmental Justice Issues in an Unincorporated Black Township.

Through each era, the southeastern United States was and continues to be an epicenter for industrial companies to establish factories and plants. Though this development attracts economic gain for the companies and surrounding areas, low-income and predominantly Black communities bear the brunt of the environmental consequences while frequently remaining stagnant economically. This qualitative, community-based participatory research study grew out of a larger study designed to recruit lay community advisors from communities labeled as hard to reach in research. We focus on Holt, Alabama, an unincorporated community in the southeastern United States region. The primary goal of this research inquiry is to thematically analyze community interviews stemming from a topic of research, practice, and policy interest to community members: the effects of industrial pollution on Holt citizens’ daily lives. Content analysis of focus-group transcripts revealed four emergent themes, including: (1) how the pollution affects their water, soil, and air quality; (2) illness related to pollution; (3) community engagement and empowerment; and (4) suggestions regarding what government officials could do to address this area of need. Building upon the prior research regarding environmental justice, human flourishing, and the definition of nurturing environments, suggestions are made regarding the creation, implementation, and maintenance of project advisory councils focused on issues of environmental justice. Community advocacy and empowerment as well as community and scientific partnerships are imperative to alleviate problems associated with environmental justice.

Broad-Leaved Tree Growth Modulated by Industrial Air Pollution in the Northern Romania (Baia Mare Region)

Atmospheric pollutants over the last century have led to increased negative impacts on the environment, especially on forest ecosystems. In the Baia Mare region of Romania, the influence of pollution on the neighboring forests of the municipality has been reported since 1970, and its negative effects have been reported mainly in the form of reduced tree growth, which implies significant losses of wood biomass. The objective of this study is to analyze the temporal and spatial effect of industrial pollution on the auxological processes of beech trees in this region. Quantification of auxological changes was performed by analyzing the resilience, recovery and resistance indices. The most intense negative effect of local pollution with heavy metal dusts, sulfur and nitrogen oxides, and sulfuric acid vapors, on the auxological processes of beech trees was found in the period 1960–1990, with a maximum in the period 1970–1980, when the mining activity was at its highest intensity. Beech trees responded to the negative effect of pollution by significantly reducing their growth during the period affected by local pollution, and after 1990 they resumed their auxological activity close to normal. In addition, it was noted that the index that best captures the effect of pollution over time is the resilience index. Tree growth resilience, recovery, and resistance assessment and analysis significantly contributes to our understanding of trees response to environment pollution more broadly creating also the base for strategic planning initiatives with valuable insight into the efforts of making the forests more resilient and resistant.

“Passing Down Pollution”: (Inter)generational Toxicology and (Epi)genetic Environmental Health

Concern about the harmful health effects of industrial pollution is increasingly taking on an intergenerational dimension. In environmental health sciences such as toxicology, this has resulted in emphasizing the influence of toxic chemicals, substances, and situations across generations. Toxic relationalities are now being explored through research on gene-environment interaction, including toxicogenomics and epigenetic research through animal experiments and birth cohort studies. Based on fieldwork conducted among reproductive and developmental toxicologists working in Nanjing, China, this article shows how toxicological research both expresses and produces renewed anxieties about "passing down pollution." These toxicological accounts of intergenerational harm problematically work through overly simplistic renderings of reproduction and biological relatedness. But they also have the potential to catalyze creative understandings of toxic relationalities and responsibilities at a moment when making kin is increasingly seen as key to securing livable futures.

Assessment of adaptive capacity of native and adventive species of trees and shrubs in Dnipro region

Nowadays, deterioration and loss of ecological functions of urban tree and shrub plantations take place in Europe and, in particular, in Ukraine; it was noted that their number is insufficient to counteract the negative impact of global climate change and protect the population against industrial pollution effects. The issue of resistance of native and adventitious tree species used in the plantations of industrial cities remains relevant; it necessitates the assessment of physiological and biochemical aspects of their adaptation to extreme environmental factors, such as moisture limit in the steppe zone, periodic dangerously low winter temperatures and anthropo-technogenic load (in large urban agglomerations). In order to optimize the assortment of tree species of large megalopolises of the steppe zone of Ukraine and determine their potential resistance to anthropogenic pressures the study was conducted in conditionally clean forest biogeocenoses of the Samara River levee zone and in artificial plantations on the territories located in the coastal zone of the Dnipro River within 1500 m from the Prydneprovskaya thermal electric station (PTES, Dnipro city). It well known that the TPP is the source of atmospheric air pollution by such heavy metals as lead and cadmium. A study of the activity of antioxidant protection enzymes in leaves of native and adventive tree species showed that in the zone of Prydneprovskaya TES impact there was an increase of guaiacol peroxidase activity in Acer platanoides, Ulmus minor, Morus alba; benzidine peroxidase in Acer negundo, Ulmus laevis, Acer platanoides; catalase in A. platanoides, A. negundo, U. laevis, Ulmus pumila and Robinia pseudoasasia. High peroxidase activity, which is complemented by higher catalase activity, indicates the relative resistance of these species to atropo-technogenic pressures supported by antioxidant defense mechanisms. Total chlorophyll content (Chla + Chlb) in leaves of native species Ulmus laevis, Acer platanoides and adventive Morus alba decreased in the zone of TPP impact in relation to conditionally clean areas. The ratio of chlorophyll a to chlorophyll b in contaminated areas significantly increased in leaves of native species Ulmus laevis, Ulmus minor, Acer platanoides compared with control. The invasive species Acer negundo, Morus alba, Ulmus pumila had no significant changes in this indicator. In invasive species such as Ulmus pumila, Acer negundo there was an increase in leaf mass, which may indicate adaptation of these species to anthropogenically altered growth conditions.

The effects of industrial pollution on ecosystem service value: a case study in a heavy industrial area, China

The effects of industrial pollution on ecosystem service value: a case study in a heavy industrial area, China

Effects of industrial pollution on the reproductive biology of Squalius laietanus (Actinopterygii, Cyprinidae) in a Mediterranean stream (NE Iberian Peninsula).

Mediterranean rivers are severely affected by pollutants from industry, agriculture and urban activities. In this study, we examined how industrial pollutants, many of them known to act as endocrine disruptors (EDCs), could disturb the reproduction of the Catalan chub (Squalius laietanus). The survey was conducted throughout the reproductive period of S. laietanus (from March to July 2014) downstream an industrial WWTP located in the River Ripoll (NE Iberian Peninsula). Eighty fish (28 females and 52 males) were caught by electrofishing upstream and 77 fish (33 females and 44 males) downstream a WWTP. For both sexes, the gonadosomatic index (GSI) and gonadal histology were examined and related to water chemical analysis and fish biomarkers. Female fecundity was assessed using the gravimetric method. Fish from the polluted site showed enhanced biomarker responses involved in detoxification. Also, in the polluted site, lower GSI values were attained in both sexes and females displayed lower numbers of vitellogenic oocytes. Gonadal histology showed that all maturation stages of testicles and ovaries were present at the two study sites but fish males from the polluted site had smaller diameter seminiferous tubules. Water chemical analysis confirmed greater presence of EDCs in the river downstream the industrial WWTP. The chemicals benzotriazole and benzothiazole could be partially responsible for the observed alterations in the reproductive biology of S. laietanus.

Assessment of industrial pollution effects in coastal seawater (Northeastern Mediterranean Sea) with chemometric approach

ABSTRACT The aim of this study was to evaluate heavy metal pollution in coastal seawater collected from industrial and non-industrial areas of Iskenderun Bay. The concentrations of heavy metals (Fe, Ni, Mn, Cr, Cu, Zn, Cd, Pb, Co and Al) in the seawater samples were determined by inductively coupled plasma optical emission spectrometry (ICP-OES). The accuracy of the methods was confirmed by certified reference materials. The relative standard deviation for the analytical procedure was better than 5%. Seasonal changing of some physicochemical parameters (temperature, pH, dissolved oxygen, electrical conductivity and total dissolved solids) in seawater samples have been investigated for the assessment of quality of coastal seawater in Iskenderun Bay. Chemometric techniques (principal component analysis, cluster analysis and correlation analysis) were used to classify of the water samples. The obtained results allowed the determination of two major clusters, reflecting the groups of unpolluted and polluted stations. On the basis of the chemometric approach, it was found that some locations were under the influence of factory contamination within the observed time period. The study showed that the use of chemometrics provides useful and promising indicators to evaluate the data.

Diversity of ants (Hymenoptera, Formicidae) along a heavy metal pollution gradient: Evidence of a hump-shaped effect

Abstract Ants, as indicators of ecological changes, are widely used in land management and environmental monitoring. At the same time, effects of industrial pollution are less known compared to many other stressors. We studied variations in habitat variables and ant diversity near the Karabash copper smelter (KCS) in Russia, in 2009 and 2014. Pitfall traps were set up at 10 birch forest sites (3 plots per site and 5 traps per plot) located to the north and south of the smelter within a 1–32-km range, with two samplings per season (June and August). The tree height, stand basal area, species richness of the field and moss layers, and the cover of the field layer decreased towards the smelter. The vegetation almost disappeared at the industrial barren close to KCS. In total, 21 ant species of 7 genera were registered. The highest species richness, diversity, and total occurrence of ants were observed in the transitional zone between moderately polluted forest habitats and industrial barren. Ant diversity and occurrence showed the same pattern in different years. Our results conform to the intermediate disturbance hypothesis predicting the greatest diversity at intermediate frequencies or intensities of disturbance or environmental change. Apparently, contaminant exposure affects ant communities near KCS indirectly, through habitat transformation. The study emphasizes the need for thorough planning of field studies of pollution effects on ants with examination of the full range of exposures. In addition, the nonlinear pattern of diversity and abundance of the ant community along the pollution gradients suggests caution, when assessing the magnitude of human impact and the state of ecosystems with ants as bioindicators.

Root structural changes of two remediator plants as the first defective barrier against industrial pollution, and their hyperaccumulation ability.

In the present day, plants are increasingly being utilized to safeguard the environment. In this study, we used Salsola crassa M. B. and Suaeda maritima L. Dumort for phytoremediation of water contaminated with heavy metals and simultaneous examination of the effect of industrial pollution on their root structures. After irrigation of a treatment group with wastewater and a control group with fresh water for 3months, we fixed the root parts in the FAA fixator for developmental study, and measured the concentrations of Co, Ni, Zn, As, Cu, and Pb in the roots, shoots, soil, and irrigating water. The plants irrigated with wastewater showed significant accumulation of heavy metals in the roots and some translocation of heavy metals from the roots to the shoots. We also performed an experiment with two 0.3m3 pools to more closely study the feasibility of these plants for filtering water of contaminants, including mineral compounds, and altering its chemical characteristics. In our anatomical studies, the cells of the treatment roots showed irregularities and abnormal appearances in all tissue layers. The diameter and area of the xylem and the size of the cortical parenchyma have increased in the treatment plants of both species, confirmed by Stereolite software. Phytoremediation studies indicated that S. crassa accumulated As, Cu, Zn, Pb, Co, and Ni, and S. maritima accumulated As, Co, Zn, and Cu. S. crassa accumulated more heavy metals in its roots, whereas S. maritima accumulated more in its shoots. The biological oxygen demand and chemical oxygen demand were also significantly reduced in the wastewater passed through pools with S. crassa. Our results indicate that both genera are hyperaccumulators of heavy metals and therefore hold promise for industrial wastewater treatment, especially the absorption of As.

Effect of Industrial Pollution of the Environment on the Frequency of Abnormal Spermatozoa in the Bank Vole, Myodes glareolus

Bird diversity and dissimilarity show contrasting patterns along heavy metal pollution gradients in the Urals, Russia.

The effects of industrial pollution on bird diversity have been widely studied using traditional diversity measures, which assume all species to be equivalent. We compared species richness and Shannon index with distance-based measures of taxonomic, functional, and phylogenetic diversity (the abundance-weighted mean nearest taxon distances), which describe within-community dissimilarity at terminal branches. Analysis of dissimilarity can shed light on the processes underlying community assembly, i.e., environmental filtering decreases dissimilarity whereas competitive exclusion increases it. In the 2-year study near Karabash and Revda copper smelters in Russia, point counts of nesting birds and habitat descriptions were taken at 10 sites (40 plots) along each pollution gradient. The abundance and diversity of birds showed good repeatability in both regions. The total density of birds, number of species per plot, and Shannon diversity decreased at high toxic load in both regions. The taxonomic, functional, and phylogenetic nearest taxon distances showed the same pattern within regions. Species dissimilarity within communities increased with pollution in Karabash (due to loss of functionally similar species), but did not change in Revda (due to mass replacement of forest species by species of open habitats). Pollution-induced changes in bird communities near Karabash were greater due to the stronger deterioration of the forest ecosystems and less favorable natural conditions (more arid climate, lower diversity and vitality of the tree stand and understorey) compared to Revda. This study emphasizes the need for a multi-level approach to the analysis of bird communities using traditional indices of diversity, functional, taxonomic, or phylogenetic distances between species and environmental variables.

An assessment to the oligopoly cement industry in Egypt: is it a curse or a blessing?

The purpose of this case study is to investigate the Egyptian cement industry's role in growth and development. Cement plays a crucial role in meeting societies' demand for real estate and construction materials. In many emerging countries and especially those characterised by an increasing rate of population, consumption of cement will continue. This present case study aims to estimate the pollution load for the cement industry in Egypt using an industrial pollution projection system (IPPS). This estimation will provide an assessment of the effects of industrial pollution in Egypt, and to analyse the market's driving forces and to guide the government with information to priorities its objectives with regard to the competing demands of pollution, growth and development.
