Abstract

Investigations were carried out in order to evaluate biodegradability of two pesticides - pure active substance 2,4-dichlorophenoxyacetic acid (2,4 D) and specific preparation created at the base of 2,4-D - Aminopielik 720. Biodegradation was carried out according to OECD standards - Method 301E and 303A. After biodegradation toxicity of intermediates was also determined. Investigated preparations were biodegradable in coupled units test Biodegradation rate, observed at the base of COD standard analysis, was over 90%. Intermediates didn't show significant toxicity with reference to fish, algae and daphnia.
