Organochlorine residues in River Po sediment: testing the equilibrium condition with fish. 1986

S Galassi, and M Migliavacca

Organochlorine residues have been determined in sediment samples collected in the River Po, during 1980-1982 at five sampling stations. Significant higher levels have been observed in a deposition area after the confluence of a very polluted tributary. No significant differences could be observed with respect to the sampling period. Residue concentrations in sediment were correlated with the organic matter content. By using soil partition coefficients and bioconcentration factors in fish, pesticide and PCB concentrations in fish have been calculated from sediment values and compared with measured values from a previous investigation. Tentatively a quality criterion for PCB in sediment is proposed.

D011078 Polychlorinated Biphenyls Industrial products consisting of a mixture of chlorinated biphenyl congeners and isomers. These compounds are highly lipophilic and tend to accumulate in fat stores of animals. Many of these compounds are considered toxic and potential environmental pollutants.

D002849 Chromatography, Gas Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix. Chromatography, Gas-Liquid,Gas Chromatography,Chromatographies, Gas,Chromatographies, Gas-Liquid,Chromatography, Gas Liquid,Gas Chromatographies,Gas-Liquid Chromatographies,Gas-Liquid Chromatography
D003634 DDT A polychlorinated pesticide that is resistant to destruction by light and oxidation. Its unusual stability has resulted in difficulties in residue removal from water, soil, and foodstuffs. This substance may reasonably be anticipated to be a carcinogen: Fourth Annual Report on Carcinogens (NTP-85-002, 1985). (From Merck Index, 11th ed) 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane,4,4'-DDT,4,4'-Dichlorodiphenyltrichloroethane,Benzochloryl,Chlorophenothane,TbisC-ethane,p',p'-DDT,4,4' DDT,4,4' Dichlorodiphenyltrichloroethane,TbisC ethane
