The water quality of the Cisadane River, located in the industrial factory area, it is contaminated with copper, it is necessary to treat sewage. Biological wastewater treatment using bacteria is a more economical and effective method of removing copper from the environment than chemical methods. This study aims to isolate, identify, determine the level of resistance, and analyze the ability of bacteria to accumulate copper. Isolation was carried out by the spread method in Luria Bertani Agar medium containing CuSO4. Bacterial isolates were identified based on analysis of the 16S rDNA gene. The resistance level is determined based on the Minimum Inhibitory Concentration (MIC) value. The accumulation ability of copper was determined using an atomic absorption spectrophotometer. Six bacteria resistant to copper were isolated and identified as Pantoea agglomerans strain IrCis1, Klebsiella grimontii strain IrCis3, Klebsiella penumoniae strain IrCis4, Shigella flexneri strain IrCis5, Enterobacter cloacae strain IrCis6, and Enterobacter cloacae strain IrCis9 with MIC of 7 mM - 9 mM. Pantoea agglomerans strains IrCis1, Klebsiella grimontii strains IrCis3, Klebsiella pneumoniae strains IrCis4 can accumulate copper of 1,19 mg, 1,39 mg, and 0,92 mg, respectively, per gram of dry cell weight.

THE TRANSFORMATION OF PUBLIC AND PRIVATE SPACES ALONG ISMET INONU-2 BOULEVARD

The aim of this study is to examine the changes in the identity of the Ismet Inönü-2 Boulevard in the Eskişehir Old Factory Area through the transformation of public and private spaces in historical context. In the study, first, the three eras that are; the development of the Boulevard due to the industrialization of the Early Republican period, the situation up to the year 2000 and the rapid transformation process witnessed after 2000 will be given chronologically. Then, spatial transformations on the Boulevard, which are the indicatives of the socio-economic changes, will be discussed through concepts derived from the literature survey. These concepts will also be exemplified and concretized through the field work conducted in the Boulevard. It is inferred from the investigation that the identity of the Boulevard related to industrialization and production disappeared and a new identity has arisen due the consumption spaces such as Cafés, Restaurants, Hotels, Office Blocks and Shopping Centers surrounding the Boulevard through the revisions of the development plans. According to the findings obtained during the study, İsmet İnönü-2 Boulevard reflects socio-economic transformations with the qualities and the transformations of the private and public spaces it hosts. The street, which is re-structured evolving from the production society to the consumer society, is an “invented street” and the interface built on the street produces private publicities and excludes the public.

Characterization of sugar factory effluents from different factories of north coastal Andhra Pradesh, India and its effect on soil properties

Sugarcane is important sugar crop which is accounting for approximately 80 percent of world sugar production. Sugarcane is one of the important agro industrial crops of commercial importance grown in North Coastal Andhra Pradesh, India. During processing of cane, sugar mills will discharge huge amounts of wastewater as large quantities of water is utilized in sugar mills. However, water resources are limited and a wide gap exists between available water supply and the amount of water required for intensive cropping, appropriate use of industrial effluents may be helpful in meeting a part of the increased water demand. No systematic study has been carried out so far to assess the relative heavy metals availability in soils irrigated with effluent waters. Therefore, a study was undertaken to survey both surface and subsurface soils irrigated with effluent waters for availability of heavy metals and also to assess the contents of the pollutant elements in sugar industrial effluents at the point of source. Survey of effluents and irrigation waters for their quality (heavy metal, RSC, SAR, pH and EC) with special reference to sugarcane cultivation in different factory zones of North Coastal Zone was carried out during 2011-12 and 2012-13.Effluents samples were collected from all the five existing sugar factory areas of North Coastal Andhra Pradesh viz., M/s Thummapala Cooperative sugar factory, Anakapalle, M/s Etikoppaka Cooperative sugar factory, Darlapudi and M/s Govada Cooperative sugar factory, Chodavaram of Visakhaptanm district; M/s GMR Sugar factory, Sankili of Srikakulam district and M/s NCS sugars, Bobbili of Vizianagaram district. Results revealed that all sugar factory effluents are highly acidic with the pH values varying from 4.32 (M/s Govada Cooperative sugar factory, Chodavaram) to 5.50 (M/s Etikoppaka Cooperative sugar factory, Darlapudi). However after effluent treatment, the pH values in all the factory areas were reached to safer limits. Concentrations of magnesium, calcium, sodium and sodium absorption ratios are within the limits in all the factory effluents. Heavy metals viz., cadmium and lead also not recorded in factory effluents, whereas cobalt, nickel and chromium are found in traces. Hence, effluents from all the sugar factories can be used safely for irrigation with respect to concentration of heavy metals in the sugar factory effluents. Data on soil analysis results revealed that, effluent irrigated soils are neutral in reaction with non-saline in conductivity. Mean organic carbon content pertaining to all the five factory soils was medium in range. Hence, it is found safe to irrigate soils with treated sugar factory effluents as of soil physico-chemical and chemical properties are at permissible limits and for sugarcane cultivation.

Accident consequence calculation of ammonia dispersion in factory area

With the widespread use of ammonia in the process industry, more and more accidents were caused by ammonia leakage and dispersion. The dispersion of ammonia is determined by its physical properties, release source conditions and atmospheric environment. Full-scale numerical simulation based on CFD theory was carried out to study the dispersion law of ammonia in a food factory. It was found that ammonia concentrated on the symmetric plane and showed an upward movement near the source. Moreover, the effect of pressure on the dispersion of ammonia was explored showing that the concentration of ammonia near the source increased with the increase of pressure, while the dispersion of ammonia far from the source is mainly influenced by wind field. Last but not the least, the dangerous area completely covers the obstacle region according to the harmful concentration, but the lethal concentration range and explosion range both only existed near the release source. Correspondingly, the concentration of ammonia in the region far from the symmetric plane can be regarded as a safe area. When the accident happens, one should stay away from the release source and evacuate towards the sides in a timely manner. We hope that this work can provide an effective method in predicting the impact of ammonia dispersion and can arouse concerns over the public safety.

Dual C–Cl isotope analysis for characterizing the anaerobic transformation of α, β, γ, and δ-hexachlorocyclohexane in contaminated aquifers

Hexachlorocyclohexanes (HCHs) are widespread and persistent environmental pollutants, which cause heavy contamination in soil, sediment and groundwater. An anaerobic consortium, which was enriched on β-HCH using a soil sample from a contaminated area of a former pesticide factory, was capable to transform α, β, γ, and δ-HCH via tetrachlorocyclohexene isomers stoichiometrically to benzene and chlorobenzene. The carbon and chlorine isotope enrichment factors (εC and εCl) of the dehalogenation of the four isomers ranged from −1.9 ± 0.3 to −6.4 ± 0.7‰ and from −1.6 ± 0.2 to −3.2 ± 0.6‰, respectively, and the correlation of δ37Cl and δ13C (Λ values) of the four isomers ranged from 1.1 ± 0.1 to 2.4 ± 0.2. The evaluation of Λ and the apparent kinetic isotope effects (AKIE) for carbon and chlorine may lead to the hypothesis that the two eliminated chlorine atoms of α- and γ-HCH were in axial positions, the same as for the β-HCH conformer which has six chlorine atoms in axial positions after ring flip. The dichloroelimination of δ-HCH resulted in distinct AKIE and Λ values as one chlorine atom is in axial whereas the other chlorine atoms are in the equatorial positions. Significant chlorine and carbon isotope fractionations of HCH isomers were observed in the samples from a contaminated aquifer (Bitterfeld, Germany). The 37Cl/35Cl and 13C/12C isotope fractionation patterns of HCH isomers from laboratory experiments were used diagnostically in a model to characterize microbial dichloroelimination in the field study. The comparison of isotope fractionation patterns indicates that the transformation of HCH isomers at the field was mainly governed by microbial dichloroelimination transformation.

Assessment of malaria as a public health problem in and around Arjo Didhessa sugar cane plantation area, Western Ethiopia

BackgroundAlthough much progress has been made in reducing malaria morbidity and mortality worldwide in the last decade, nationally malaria remains the third leading cause of death and still considered a major public health problem. Therefore, this study was aimed to assess malaria as a public health problem in and around the sugar cane plantation area of Arjo Didhessa sugar factory, Western Ethiopia.MethodsA community-based cross-sectional study supplemented with clinical retrospective data, which included 452 study subjects was recruited and the study period was extended from May 2016 up to November of 2017. A standardized questionnaire was used to assess malaria risk factors and blood samples were received from all study participants and further subjected to Giemsa staining for determination of malaria prevalence. Data were analyzed by SPSS version 20. Malaria risk factors were identified by multivariate logistic regression at a significance level of P < 0.05.ResultsThe overall malaria prevalence was 3.1%; Plasmodium vivax is the main type of malaria parasite. Overnight outdoor sleeping and improper utilization of mosquito bed nets were found to be statistically significant as malaria risk factors in the community. In the retrospective studies of five years, the peak malaria cases (13.84%) were reported in 2013 and the lowest cases (1.24%) in 2017.ConclusionsThe figure for malaria witnessed in this area remains higher than the observed national malaria prevalence indicating malaria remains a public health problem. Therefore, we suggest the factory administrators and health care professionals work more on raising awareness to avoid night outdoor sleeping and promote frequent and appropriate utilization of insecticide-treated nets in line with regular indoor residual spraying.

Impact of Trichogramma release regimes and combination with mass trapping on sugarcane internode borer (Chilo sacchariphagus indicus) management

Large area study on the impact of six versus ten releases of the biocontrol agent, Trichogramma chilonis , besides large plot assessment of ten releases with and without mass trapping (by pheromone traps) for eco-safe management of the sugarcane internode borer (INB) - Chilo sacchariphagus indicus Kapur were undertaken in Natems Sugar factory area, Koppedu Taluk, Chittoor District, Andhra Pradesh, South India. In 2017-18, a large contiguous sugarcane crop area of 400 hectares received six releases of T. chilonis (as Tricho cards @ 5cc.ha/release) in alternate weeks during 5-7 months age of crop, followed by four additional releases during 8-9 months age (totalling ten releases) in 40 hectares area, besides assigning a no release block of 40 hectares in adjacent area. Harvest-time sampling in each treatment block showed that the INB distribution (per cent canes infested) was 80 % in control (no release) block, while it was 42 and 27 %, respectively, for six and ten releases. The INB intensity (per cent internodes infested) was also more (6.2 %) in control block whereas it was only 3.2 % and 1.5 %, in the two respective release regimes. Based on these results the cost-effectiveness of both the regimes was ascertained. In 2018-19, the impact of ten releases of T. chilonis (@5cc/hectare /release) versus same regime plus mass trapping (@25 pheromone traps/ha) was compared in large plots (each of 2.0 ha) along with an untreated control plot. Harvest-time samples showed that INB distribution was 70.3% in control block, compared to 48.3% in Trichogramma release block versus 19.8% in block combining Trichogramma and mass trapping. The respective INB intensity was 6.04 %, 4.04 % and 2.17 % while the estimated cane yields were 81.0, 86.2 and 92.5 tons/ha, respectively. The cost: benefit ratios for Trichogramma release with and without mass trapping were comparable, so confirming that both are cost-effective alternatives to chemical insecticide use in sugarcane agro-ecosystems.

The Potential Impact Analysis of Ammonia Gas Leakage On Refrigeration System Using Aloha Software (Case Study At PT. Cahaya Gunung Foods)

A refrigeration system uses Ammonia Anhydrous in the liquid phase and the gas phase. The refrigeration system has the potential for gas leakage, which poses a risk to worker safety as well as environmental pollution to water bodies and air pollution. This risk might have an impact on employees in the factory area and could extend to the surrounding community. This study is intended to be able to analyze the risk of pollution accurately before installing the refrigeration installation. In this study, the analysis method that will be used is the statistical method and the use of mathematical models supported by Aloha software. The distribution of pollutants from ammonia gas leakage is influenced by several factors, including the capacity of the refrigeration system, meteorological conditions, and land use. The use of Aloha software in the prediction of zones affected by the spread of toxic substances in the atmosphere can calculate and predict the area affected by leakage events. With modelling done, will get a map of concentration and impacted area. The direction and magnitude of the impact of pollution will be known immediately, and the potential losses that may arise will be minimized.

Bacterial growth dynamics and corresponding metabolite levels in the extraction area of an Austrian sugar beet factory using antimicrobial treatment.

During the manufacture of sucrose from sugar beet, different microorganisms originating from the plant material as well as from the soil enter the process. Due to the formation of polysaccharide-based slimes, these contaminants may induce several adverse effects such as filtration problems during juice purification. Certain microorganisms also metabolize sucrose, leading to product losses with financial consequences. To better understand and to prevent these negative effects, the aim of the study was to investigate the evolution of relevant bacterial groups, including their metabolites appearing during the extraction process. For this purpose, one production cycle was monitored to identify the major contamination steps and to clarify how they relate to the processing conditions. Traditionally, different antimicrobial agents such as formaldehyde, sulfur dioxide, hypochlorous acid, sodium hypochlorite, and chlorine dioxide have been added to inhibit microbial growth. In the present study, a rosin-based product derived from pine trees was applied as an alternative to those substances. Press water, raw juice, and mid-tower juice were identified as being highly contaminated with bacteria, and processing conditions such as time, temperature and pH level significantly influenced bacterial levels and the corresponding metabolites. Among the contaminants identified, lactic acid bacteria, and mesophilic and thermophilic aerobic bacteria played a dominant role, whereas lactic acid, acetic acid, butyric acid, and ethanol were identified as typical metabolites. Bacterial growth during production could be reduced by shock dosing of the rosin-based material in the extraction area. © 2020 Society of Chemical Industry.

The Capitolium at Baelo Claudia (Bolonia): new data from the sculptures

The excavations carried out between 1917 and 1921 at Baelo Claudia (Bolonia, Tarifa, province of Cádiz)1 were led by P. Paris and his team2 working with the Anglo-French archaeologist G. Bonsor3 and with A. Laumonier and R. Ricard, as well as with Cayetano de Mergelina4 in 1918-19. Work focused on the N part of the forum where three temples were exposed.5 A minor intervention was carried out in the theatre together with more extensive excavations in the area of the fish-salting factory that included two domus, and in the E necropolis.

PERBANDINGAN SIFAT KIMIA AIR SUNGAI CISADANE PADA TATA GUNA LAHAN YANG BERBEDA

The study that examined the analysis of the chemical properties of the Cisadane River in Tangerang City was carried out from April to June 2019, to compare the water quality of the Cisadane river through chemical properties in three types of land use. The study used a survey method by determining the sampling of the test material and measuring water quality carried out by purposive sampling, adjusted for the sinking of the land. Sampling points for fisheries area and housing areas are in Karawaci Hilir (station 1), Babakan (station 2) and Sukajadi (station 3). The sampling point of the factory area is around the tofu mill (station 1), the paper mill (station 2) and the palm oil mill (station 3) all in Karawaci Hilir. Data analysis in the laboratory includes DO, COD, BOD and PO4. The results showed that water quality in the catchment area of fishermen had DO, BOD, COD and PO4 values that met water quality standards, except at station 3 which had very high BOD and COD values, presumably due to disposal of construction waste and household waste. For residential areas, only high BOD content exceeds the water quality standard. Whereas in the factory area, low DO levels indicate that it is not feasible for aquatic biota life. The BOD content is high at all stations, the COD content is very high only at station 2, which is indicated by the large amount of water hyacinth that grows and a very strong odor. In general, the water quality of the Cisadane River in three types of land use needs special handling to prevent environmental pollution.Keywords: water quality standards, water quality, Cisadane River, chemical properties, land use

Radioactivity and Radiological Risks of Soil Exposure to Workers: a Case Study of Production Company in Ota, Ogun State, Nigeria

Background dose assessment has been carried out in and around a production company using Gamma Ray Spectrometer (Super Spec. 125 model). This was done to identify the zones that could pose health risks to workers. The geospatial maps for easy identification of radionuclides occurrence in the factory was determined using geospatial analysis. The highest exposure dose was found at the restaurant and factory areas whereas the lowest background dose was noted at the entrance of the company. The absorbed dose rate of 199.88nGry/h is 0.4 % higher than the world average value according to UNSCAER, 2000. The geospatial analysis revealed that the natural radionuclides in the region have a trend, NW-SE trending with significant re-deposition at the western part. This could be caused by the diffusion of chemical weathering and complexation of Dahomey (Benin) basin soil geology from human activities. The boxplot identified the radionuclides distributions which are in the order of magnitudes 40K>238U>232Th in the study area. Significantly, the geospatial analysis of the background gamma dose rate has revealed the hot spots in the area which may pose health risk to the workers if adequate measure is not taken to advise workers not to spend much time at the hot spot zone.
