Title: Assessment of synthetic organic compounds, and endocrinology and histology of carp in Lake Mead

Abstract

This study investigated the presence and biologic effects of synthetic organic compounds transported by Las Vegas Wash to Lake Mead National Recreation Area. Water, bottom sediment, and carp (Cyprinus carpio) were analyzed for synthetic organic compounds. Semipermeable membrane devices (SPMDs) were used to sample the water column. Blood samples were collected from Carp for analysis of sex steroid hormones and vitellogenin. Samples of external abnormalities and organs (liver, gill, kidney, small intestine, and gonad) were collected for histologic analysis. Compounds known to affect endocrine systems (PAHs, phthalate esters, PCBs, dioxins and furans) were detected in SPMD, bottom-sediment, and/or carp samples. The number and concentrations of compounds generally were greater in samples from Las Vegas Wash and Bay, than in samples from Callville Bay, a reference site in Lake Mead. High levels of PAHs detected in SPMDs from Callville Bay could indicate the existence of contaminant sources other than Las Vegas Wash.
