UV and temperature effects on chloroacetanilide and triazine herbicides degradation and cytotoxicity.

ABSTRACT: The purpose of this study was to explore the stability and toxicity of the herbicides and their degradation byproduct after exposure to different environmental factors. Triazines (atrazine, propazine, simazine) and chloroacetanilides (acetochlor, alachlor, metolachlor) which are commonly used herbicides were evaluated for cytotoxicity in different UV (254 nm and 365 nm) and temperature (4 °C, 23 °C, and 40 °C) conditions as well as degradation rates. Atrazine with the highest LD₅₀ (4.23 μg mL^-1) was less toxic than the other tested triazine herbicides Chloroacetanilides tested were more toxic than tested triazines, with LD₅₀ 0.08-1.42 μg mL^-1 vs 1.44-4.23 μg mL^-1, respectively. Alachlor with LD₅₀ 0.08 μg mL^-1 show
