Abstract

Data presented in this paper indicate chronic pesticide levels present in oyster (Crassostrea virginica) tissue from all Texas bay areas sampled, including Galveston Bay. Random samples of fish and bird tissue show the scope of contamination is much greater than first suspected. These data indicate only the degree and sequence of pollution in specific areas. The need is shown for (1) an intensified investigation of persistant pesticides present in streams entering the areas sampled and (2) the effects of chronic levels of pesticide toxicants on the marine environment.
