Toxicity of Paraquat and Dicamba on Caenorhabditis Elegans LC50 Value

Abstract

Paraquat and dicamba are chemicals commonly used in agriculture for plant control. The US Environmental Protection Agency (EPA) has classified paraquat into a restricted use class for use only by practitioners, as it is highly toxic. In this study, the effects of different concentrations of paraquat and dicamba toxic substances on C. elegans were studied. In tests, C. elegans were directly exposed to different concentrations of paraquat and dicamba for 6h, 12h, 18h, 24h. In particular, it was determined at which paraquat and dicamba doses that half of the C. elegans individuals (LC50) died. In the analysis results, paraquat LC50 values were found as LC50 6h= LC50 6h= 7412 µM, LC50 12h= 459 µM, LC50 18h= 123 µM, LC50 24h= 61 µM. Similarly, dicamba LC50 values were found as LC50 6h= 14610 µM, LC50 12h= 1404 µM, LC50 18h= 906 µM, LC50 24h= 463 µM.
