Spirulina Platensis and Bioremediation of Phosmet, Ethion, Methyl Parathion pesticides

Abstract

In this study, the bioremediation efficiency of some pesticides in Toxic Industrial Chemical category of CBRN (Chemical, Biological, Radioactive, Nuclear) threats with blue-green microalgae was investigated. Although these pesticides are highly harmful to human, living and environmental health, they are highly persistent in nature. Recently, the increasing demand and use of pesticides in the agricultural field poses risks in production, transportation and storage areas. The microalgae we have used are already known for its ability to metabolize pesticides, as well as its use in important areas, especially in the medicine and pharmaceutical industry. Using environmentally friendly bioremediation technique to eliminate or minimize the harmful effects of pesticides contributes to nature and the future. The fact that the selected microalgae and pesticides have not been investigated before proves the originality of our study. Pesticide remediation amount measurements were made by electrochemistry method and it was determined that Spirulina platensis removed Phosmet, Ethion and Methyl Paration by 70.0%, 61.0%, 50.0%, respectively, at the end of the 7th day.
