“…The overall geological setting and the hydrogeological situation of the investigation area has been described previously (Wycisk et al 2003;Heidrich et al 2004). Briefly, the complex system is characterized by two main superimposed aquifers of different heterogeneity, which are partly affected by the former activity of open-cast lignite mining.…”

“…The Bitterfeld/Wolfen region (Sachsen-Anhalt, Germany) comprises a contaminated area of about 25 km 2 as a result of the former chemical industry (Wycisk et al, 2003). Chlorinated aliphatic compounds constitute the most abundant and relevant contaminated group encountered over large parts of the contaminated area but other contaminants such as benzene, toluene, ethylbenzene, and xylene (BTEX) also occur on a regional scale and form overlapping plumes (Heidrich et al 2004).…”

The variability of hydrogeochemical conditions can affect groundwater microbial communities and the natural attenuation of organic chemicals in contaminated aquifers. It is suspected that in situ biodegradation in anoxic plumes of chloroethenes depends on the spatial location of the contaminants and the electron donors and acceptors, as well as the patchiness of bacterial populations capable of reductive dechlorination. However, knowledge about the spatial variability of bacterial communities and in situ biodegradation of chloroethenes in aquifers is limited. Here, we show that changes of the bacterial communities, the distribution of putative dechlorinating bacteria and in situ biodegradation at the border of a chloroethenes plume (Bitterfeld, Germany) are related to local hydrogeochemical conditions. Biotic reductive dechlorination occurred along a 50 m vertical gradient, although significant changes of the hydrogeochemistry and contaminant concentrations, bacterial communities and distribution of putative dechlorinating bacteria (Dehalobacter spp., Desulfitobacterium spp., Dehalococcoides spp., and Geobacter spp.) were observed. The occurrence and variability of in situ biodegradation of chloroethenes were revealed by shifts in the isotope compositions of the chloroethenes along the vertical gradient (δ 13 C ranging from −14.4‰ to −4.4‰). Our results indicate that habitat characteristics were compartmentalized along the vertical gradient and in situ biodegradation occurred with specific reaction conditions at discrete depth. The polyphasic approach that combined geochemical and biomolecular methods with compound-specific analysis enabled to characterize the spatial variability of hydrochemistry, bacterial communities and in situ biodegradation of chloroethenes in a heterogeneous aquifer.

“…Literature provides evidence on some heavy contamination episodes by HCH due to formulation factories and their illegal muck dumping (Table 1). Such HCH dumpsites have been found all over the world and have been reported from Brazil (Rio de Janeiro; Oliveira et al 2003); Spain (Pontevedra; Concha-Grana et al 2006;Vega et al 2007), Bilbao (Mohan et al 2006); Germany (Chemnitz; Boltner et al 2005; Bitterfeld; Kalbitz and Popp 1999;Wycisk et al 2003); the US (North Carolina; Earth fax 2002), and India (Lucknow; CAPE http://www.panna.org/ campaigns/docsLindane/lindaneDirtySecret.pdf).

Recently, alpha-, beta- and gamma-HCH have been nominated by the POPs Reviewing Committee for inclusion into the Stockholm Convention to address the HCH contamination on a global level. Therefore, there is an urgent need to stop the production of lindane and remediate contaminated soil sites. Based on the monitoring studies, the promising species like W. somnifera and S. torvum may be selected for the on-site phytoremediation of HCH-contaminated soil. The mismanagement of HCH residues from the organochlorine industry and their contemporary relevance often after decades of their deposition is one key example demonstrating the necessity to evaluate the waste deposits of the respective organochlorine productions and need for a strict waste management, and the necessity of an integrated pollution prevention and control strategy for the whole organochlorine industry including also the developing countries.

“…Recently, geographic mapping has been increasingly used for epidemiology studies, particularly after the development of geographic information system (GIS) technologies that enable data analysis by means of spatial strategies and more comprehensive visual representation of information. GIS is commonly used in environmental epidemiology to assess exposure to pollutants in air (McEntte and OgnevaHimmelberger 2008), water (Wycisk et al 2003;Paliwal et al 2007), and soil (Jarup 2004).…”

The incidence of esophageal squamous cell carcinoma (ESCC), which is the eighth most common malignancy worldwide, is highest in China. The purpose of this study was to investigate the association between nitrogen compounds in drinking water with the incidence of ESCC by geographical spatial analysis. The incidence of ESCC is high in Shexian county, China, and environmental factors, particularly nitrogen-contaminated drinking water, are the main suspected risk factors. This study focuses on three nitrogen compounds in drinking water, namely, nitrates, nitrites, and ammonia, all of which are derived mainly from domestic garbage and agricultural fertilizer. The study surveyed 48 villages in the Shexian area with a total population of 54,716 (661 adults with ESCC and 54,055 non-cancer subjects). Hot-spot analysis was used to identify spatial clusters with a high incidence of ESCC and a high concentration of nitrogen compounds. Logistic regression analysis was used to detect risk factors for ESCC incidence. Most areas with high concentrations of nitrate nitrogen in drinking water had a high incidence of ESCC. Correlation analysis revealed a significant positive relationship between nitrate concentration and ESCC (P = 0.01). Logistic regression analysis also confirmed that nitrate nitrogen has a significantly higher odds ratio. The results indicate that nitrate nitrogen is associated with ESCC incidence in Shexian county. In conclusion, high concentrations of nitrate nitrogen in drinking water may be a significant risk factor for the incidence of ESCC.
