The effect of parathion on green algae

Summary Uptake of the pesticide parathion from aqueous solution by uni-cellular green algae has been investigated. The removal of parathion from solution by Chlorococcales does not occur through passive or by active permeation into the cells but by adsorption, which can be described by the. Freundlich-adsorption-isotherm equation. Investigations of partially purified cell walls phow that neither mucus, cellulose walls nor plasmamembranes adsorb parathion. The lipid containing trilaminar sheath (TLS) adsorbs the pesticide. The relevance of these results to ecological problems is discussed.
