Abstract
ABSTRACT: Spot ( Leiostomus xanthurus ) and hogchoker ( Trinectes maculatus ) from the Elizabeth River, Virginia, which is heavily contaminated with polynuclear aromatic hydrocarbons (PAHs), exhibit greatly reduced phagocytic and chemotactic activity of kidney macrophages. In addition, kidney macrophages from Elizabeth River spot were markedly deficient in generating a zymosan-induced chemiluminescent (CL) response, as were macrophages from York River spot exposed in the laboratory to Elizabeth River sediments. The CL response of hogchoker and oyster toadfish ( Opsanus tau ) macrophages was significantly depressed by exposure to 400 μg/liter tributyltin (TBT), while croaker ( Micropogonias undulatus ) CL activity was depressed at 40 μg/liter TBT. These assay techniques are proposed as potential bioindicators of environmental pollution.
