Abstract
Fresh and esturarine water algae maintained in laboratory microcosms simulating river-lake/estuary-bay systems were exposed to 14C-fenitrothion formulated with Atlox and tank mixed with Aerotex or Dowanol (11.5:1.5:1.5 wt/vol/vol). Generally, the tank mix co-solvents determined the amount of uptake and the array of derivatives formed by the algae. Typically, exposed to an Aerotex mix the ratio of ethyl acetate extractable (NP) fraction to ethyl acetate unextractable (P) fraction was 3.5:1.0; to a Dowanol mix the ratio was 1.5:1.0. Within any comparable time period, freshwater algae turned over more of the 14C-ring of fenitrothion than did the estuarine genera. Turnover was enhanced when Aerotex was the tank mix co-solvent.This publication has 2 references indexed in Scilit:
