1,1-Dichloropropene (1,1-DCP) is a contaminant present in both ground and surface waters used as sources for drinking water. Structural similarity to several compounds with known mutagenicity and carcinogenicity, and recent demonstration of mutagenic

Ault brook trout (Salvelinus fontinalis) were exposed to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) with a contaminated trout pellet diet to determine the effects of TCDD on reproduction, to document tissue-specific TCDD distribution, and to establis

The toxicity of 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin (TCDD) to the early life stages of F1 generation brook trout (Salvelinus fontinalis) was determined, when dosed by maternal transfer. Effects were compared across six treatments, including a cont

Uptake and elimination rate constants for [3H]-2,3,7,8-tetrachlorodibenzo-p-dioxin ([3H]TCDD) were estimated by exposing medaka (Oryzias latipes) to [3H]TCDD in flowing water with no solvent carriers. Uptake was determined from body burdens measured

Outputs from a physiologically based toxicokinetic (PB-TK) model for fish were visualized by mapping time-series data for specific tissues onto a three-dimensional representation of a rainbow trout. The trout representation was generated in stepwise

The bioavailability of 2,3,7,8-TCDD from municipal incinerator fly ash to freshwater fish was determined. It was observed that carp exposed to fly ash containing all 22 TCDD isomers, or the solvent extract of the fly ash, retain only 2,3,7,8-TCDD. Ex

The bioavailability of 2,3,7,8-TCDD from sediment to freshwater fish was studied in laboratory exposures. Carp (10g) exposed to Wisconsin River sediment (39 pg/g) for 55 days accumulated 7.5 pg/g. Maintaining exposured fish in clean water for an addi

A long-term laboratory exposure of lake trout to Lake Ontario sediment and smelt (food chain) provided comprehensive bioaccumulation relationships for 2,3,7,8-TCDD. The laboratory exposure was designed to investigate the rates of TCDD uptake via wate
