Accumulation and Depuration of DDTs in the Food Chain from Artemia to Brook Trout ( Salvelinus fontinalis )

Dietary accumulation of tetrabromobisphenol A and its effects on the scallop Chlamys farreri

“…Obviously, dietary uptake played a role on the accumulation of TBBPA in scallops, though cannot be compared with the role of water phase, but should not be neglected. The result was in line with observations obtained by Wang and Simpson (1996), Gilek (1996, 1997) and Okay et al (2000). These authors found that food addition enhanced the bioaccumulation of hydrophobic organic contaminants in suspension-feeding mussels.…”

“…Food may play an important role in the accumulation of organic compounds in suspension-feeders such as scallops, and many studies have considered the relatively importance of food versus water-borne organic contaminant uptake (Wang and Simpson, 1996;Gilek, 1996, 1997;Okay et al, 2000). In the present study, TBBPA levels in seawater and scallop tissues in different groups were presented in Table 1.…”

“…changes in water pumping, particle filtration and ingestion rates. However, higher food-associated contaminant intake rather than changes in pumping rate was considered to result in differences in the bioaccumulation of contaminant in other researches (Wang and Simpson, 1996;Okay et al, 2000). The algae concentration used in previous studies ranged between 140 and 150,000 cells mL − 1 Gilek, 1996, 1997;Okay et al, 2000).…”

Aquatic pollution may favor the success of the invasive species A. franciscana

“…These compounds seem to be ubiquitous in the biotic compartment of aquatic environments and have been detected in Artemia specimens in previous studies (Wang and Simpson, 1998). The contamination pattern observed in marine saltworks along the Mediterranean coast shows a great variety of organic compounds, with around a dozen of them (including chlorpyrifos) repeatedly present (Serrano et al, 2011(Serrano et al, , 2012.…”

Assessment of DDT accumulation by brine shrimp(Artemia salina)from filtered water and sewage effluent

“…Sewage * Corresponding Author 15 Downloaded by [Northeastern University] at 12:19 03 January 2015 effluent is considered as the major source of organochlorine pollutants to the coastal waters, where DDT was recorded as one of the highest concentrations found in aquatic biota living around sewage outfall (Mearns, 1981;Swartz et al, 1985;Miskiewicz and Gibbs, 1994) Direct partitioning or adsorption of these organochlorine pollutants in the aqueous medium plays a major role in the uptake of lipophilic compounds by the lower level of small aquatic organisms, mainly plankton, because of the relatively higher biomass in the smaller sizes (Bruggeman et al, 1984;Harding, 1986;Opperhuizen and Stokkel, 1988;Hoke et al, 1994). Concentrations of DDT on a wet whole-body-weight basis have been shown to be increased in higher-ranking aquatic predators (Tanabe and Tstsukawa, 1984;Wang and Simpson, 1996). However, information is scarce on the mechanism of DDT's accumulation in the lower levels of zooplanktonic biota or the role of these biota in transporting these pollutants to other larval stages of aquatic fish in the food chain system.…”
