Possible Toxicological Effect of Pesticides, Fipronil On Earthworm (Eudrilus eugeniae)

Abstract

Pollution is the preface of infect into an environment, may also defined as an unwanted modify in the physical, chemical and biological characteristics of air, water and soil which influence human life, lives of other useful alive plants and animals, industrial progress, alive conditions and florescent property Water is the most necessary & major necessaries of life. One can rarely survive without water also for a few days. At that 2/3 of the world’s float up region is enclosed by water but yet we are blank. An incubation study was conducted to know the toxicity level of Fipronil in soil fauna by using earthworm species Eudrilus eugeniae as a biomarker. The earthworm were incubated in the spiked soil, with concentration of 17ml, 18ml, 19ml, 20ml for a period of 24hours and 48 hours. From the study, 50% mortality was observed in 17ml. The LC₅₀ concentration were calculated from that it was clear that Fipronil is toxic to earthworm.
