The presence of asbestiform fibers in the environment is a problem of increasing concern. A variety of health problems in man and laboratory mammals have been linked to asbestos contamination. Few studies on the environmental impact of asbestos contamination have been conducted. we investigated the effects of crysotile asbestos on a planktonic alga (Cryptomonas erosa). Crysotile represents 95% of the asbestos mined for industrial use. Cryptomonas erosa is a representative planktonic alga commonly found in the Great Lakes area. Scanning electron micrographs show t hat asbestos fibers attach to the walls of algal cells. Cryptomonas and asbestos aggregate into clumps and settle. Statistical analysis of Cryptomonas density in asbestos treated and control samples show an exaggerated variance due to treatment with crysotile asbestos (N=24, F'=2.42, P>F'=.0349). We are presently using transmission electron microscopy to investigate the possibility of morphological damage in Cryptomonas cells due to crysotile asbestos contamination.
