Anthropogenic organic contaminants in sediments of the Lippe river, Germany

Sorption and degradation of triclosan in sediments and its effect on microbes

“…In sediment from the Shijing River (Pearl River system) in China, TCS varied from 345 to 1329 ng g À 1 with an average concentration of 739 ng g À 1 (Zhao et al, 2010). In a tributary of the Rine River, TCS was detected up to 450 ng g À 1 in sediment (Kronimus et al, 2004). Study on the dated sediment cores from urbanized estuaries indicated the preservation and accumulation of TCS (Cantwell et al, 2010).…”

Organic Contaminants in Riverine and Groundwater Systems

“…In detail, Cl 2 -to Cl 6 -benzenes, octachlorostyrene, hexachloro-1,3-butadiene and bis(chloropropyl)ethers were quantified. A distinct association to emissions derived from industrial areas situated at the lower river section has already been proposed by Kronimus et al (2004).…”

“…38) was identified in four water samples from the area of the river mouth (see Table 1). Its occurrence in Lippe river sediments was reported by Kronimus et al (2004). The main input pathways of hexachlorobutadiene into the aquatic environment are effluents of the organic chemical industry (Verschueren, 1996;Lee and Fang, 1997).…”

An Overview of the Persistent Organic Pollutants in the Freshwater System

“…These contaminants enter the fresh water system both from point and non-point sources. Point sources are defined in a spatially explicit manner both in terms of chemical residues from organic contaminants they contribute and by epidemiological factors thereof, like morbidity, mortality or community disruption [16]. Effluents from municipal sewagetreatment plants, industrial sources, storm sewer systems, mining and construction sites, etc.…”
