Abstract In Rayer Bazaar, different industries like tannery, plastic, textile, battery recycling industry etc. are increasing rapidly without considering the environmental issues and deterioration. Since chromium (Cr) pollution of this area has been widely investigated due to the presence of tannery industries, this study was focused on examining other environmental factors. Field visits and analytical results of semi-quantitative and quantitative analysis as well as three dimensional excitation emission matrix spectroscopy (3DEEM) of water, soil and vegetative tissues indicated that, the area is highly polluted in term of different environmental parameters and metal content. The extremely high lead (Pb) content of the soil (1171.7 mg/kg in summer, 2157.1 mg/kg in winter) and blackish materials of vegetative tissues (6585.6 mg/kg in summer, 1974.1 mg/kg in winter) indicates excessive lead deposition of this area that makes it a lead polluted hotspot. One of the possible sources of the extremely high lead concentration is adjacent battery recycling industry and/or other industries surrounding this area. So it is urgent to take necessary steps to find out immediate options for possible mitigation.

Laser Microprobe Mass Analysis

Using Laser Microprobe Mass Analysis (LAMMA), we studied the chemical composition of lead-induced intranuclear inclusions in rat kidney tissue prepared by three different wet chemical fixation procedures for transmission electron microscopy. Fixation with glutaraldehyde-Na2S gave the same results as fixation with glutaraldehyde only: a high lead concentration could be detected. Therefore, for lead strongly bound to proteins, precipitation procedures are not essential. Post-fixation with osmium tetroxide drastically changed the composition of the inclusions: the lead concentration decreased substantially, while sodium, calcium, and barium were introduced. The osmium tetroxide fixative was found to be the source of the contamination. It also contained aluminum, and we suggest that other proteins (e.g., in neurofibrillary tangles) might be able to take up Al out of solution and that care must be exercised in interpreting the microanalytical results of osmium-fixed material. For the microanalysis of the lead inclusions, fixation with glutaraldehyde only provides a good compromise between preservation of the ultrastructure and maintenance of the element distribution.

Systemic Nature

Research in the sphere of the Arctic industrial development often leads to the identification of clear regulatory gaps of a systemic nature. A particular example is the issue of legislative regulation of the involvement of secondary raw materials, fuel and energy resources in economic use and property turnover in the context of resource conservation and resource efficiency. In this case, secondary resources are not subject to independent regulation in general, but only as one of the elements of activities related to environmental protection. Accordingly, the conditions for the development of a system of production and consumption wastes’ effective management, the creation of a recycling industry, including the reuse of such waste, have not been formed yet. The results of the analysis given in this research paper clearly indicate the lack of development of mechanisms for stimulating the use of non-target materials and substances. Industrial enterprises that use secondary resources in production do not currently receive special advantages within the framework of the implemented industrial policy. System benefits are universal and directly related to commodity production only. However, it is necessary to apply measures to encourage industrial activities to implement projects involving the reuse of secondary resources in production, including in the Russian Arctic.

Lead exposure can damage cells directly by effecting DNA or indirectly by modifying proteins and enzymes. In Bangladesh, many working children are exposed to a very high level of lead during their early life due to their involvement with lead-oriented professions. This imposes a severe threat to the growth and development of the children. Therefore to study the effect of lead, we enrolled 60 age-matched male children, from an area of old Dhaka city, where battery-recycling shops are located, depending on their blood lead concentration. If the children had a plasma lead concentration above the WHO recommended threshold level of 10 µg/dl, we grouped them as test subjects and others as control subjects to determine the effect of lead on different biochemical parameters of the body. Compared to the controls, acculumlation of the lipid peroxidation product, malondialdehyde, increased significantly in test subjects ( p < 0.01). Lead exposure also increased the protein carbonyl content ( p < 0.05) and significantly decreased the plasma glutathione levels of test subjects compared to the controls ( p < 0.05). While comparing the lead-exposed group against controls, it was found that the percentage of damaged DNA, as measured using the Comet assay, significantly increased in tail ( p < 0.01) and decreased in head regions. All of these results suggest that high-plasma lead content may induce an oxidative stress to the study population, which may lead to DNA damage.

AbstractLeads are a key feature of the Arctic ice pack during the winter owing to their substantial contribution to the surface energy balance. According to the present understanding, enhanced heat and moisture fluxes from high lead concentrations tend to produce more boundary layer clouds. However, described here in our composite analyses of diverse surface- and satellite-based observations, we find that abundant boundary layer clouds are associated with low lead flux periods, while fewer boundary layer clouds are observed for high lead flux periods. Motivated by these counterintuitive results, we conducted three-dimensional cloud-resolving simulations to investigate the underlying physics. We find that newly frozen leads with large sensible heat flux but low latent heat flux tend to dissipate low clouds. This finding indicates that the observed high lead fractions likely consist of mostly newly frozen leads that reduce any pre-existing low-level cloudiness, which in turn decreases downwelling infrared flux and accelerates the freezing of sea ice.

In the present work we highlight the effectiveness of integrating different techniques and tools for better surveying, mapping and collecting data in volcanic areas. We use an Immersive Virtual Reality (IVR) approach for data collection, integrated with Geographic Information System (GIS) analysis in a well-known volcanological site in Santorini (Metaxa mine), a site where volcanic processes influenced the island’s industrial development, especially with regard to pumice mining. Specifically, we have focused on: (i) three-dimensional (3D) high-resolution IVR scenario building, based on Structure from Motion photogrammetry (SfM) modeling; (ii) subsequent geological survey, mapping and data collection using IVR; (iii) data analysis, e.g., calculation of extracted volumes, as well as production of new maps in a GIS environment using input data directly from the IVR survey; and finally, (iv) presentation of new outcomes that highlight the importance of the Metaxa Mine as a key geological and volcanological geosite.
