Bioremediation of organoarsenic pollutants from wastewater: a critical review

Abstract

Toxic inorganic and organic species of arsenic are present in the environment. Arsenic adversely affects health of millions of people across the world. Inorganic As species are naturally present in the earth crust and organic arsenic species are generated after entry of inorganic species in the organisms. Synthetic organoarsenic species are applied herbicide and pesticide in agriculture fields and used as animal feed additive due anti-parasitic nature. The present review briefly discusses removal of commonly used organoarsenic species by physicochemical techniques, microbial transformation, and degradation along with the recent insight of microbial application strategies for minimizing the arsenic accumulation in plants. © 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.
