Research ArticleOpen accessChemical Contaminants and Toxicity of Ganga River Sediment from Up and Down Stream Area at KanpurK. R. Beg, S. AliThe objective of this study was the sediment quality assessment of Ganga River at Kanpur city where effluents from tannery industries are discharged. Sediment samples from upstream and downstream area were collected and analyzed for trace metals and toxicity bioassay. Among various trace metals examined Cr in downstream sediment was 30-fold higher than in upstream sediment and its concentration was … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,601 accessesView PDFCite
Research ArticleOpen accessToxicity of Reference Sediment SamplesK. R. Beg, S. AliThis study was done to determine toxicity of certified reference sediment to be used for quality assurance in sediment toxicity testing program. Certified Reference Harbor Sediment (HS-4B for PAHs) and Estuarine Sediment (LGC-6137 for Trace Metals) were procured commercially from LGC Company, UK, and repeatedly analyzed against solid phase Microtox toxicity assay to determine EC50 values. Both PAHs rich and … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,718 accessesView PDFCite
