The present study focuses and assures the need for pesticide degradation from various water bodies used for irrigation and the available technologies to treat them effectively. A thorough review of the literature is done on pesticide residues present in various irrigation water sources like rivers, groundwater, river sediments, and soil which signifies the existence of pesticides in the ecosystem.This indicates the severity of water pollution due to various sources around and their adverse effect on the ecosystem. However, several technologies are available to treat these pesticides based on the classification. A Cross comparison between the technologies is done to determine the efficient technology for the treatment of irrigation water.

Electroactive polymers (EAPs), when subjected to electrical stimuli, undergo physical deformations. These polymers are broadly classified as electronic and ionic electroactive polymers, depending on the mode of transport of charges when the electric stimulus is applied. They are further classified into subcategories based on the way a particular material responds to electrical stimuli, and due to this diversification, EAPs find applications in many sectors. In this paper, the classification of Electroactive polymers is explained along with applications in a) Drug delivery due to biocompatibility, b) Actuators & sensors due to generation of high strain and adequate sensitivity to the electric field, c) Artificial muscles due to their low density and high strain capability, d) Coatings due to anticorrosive properties of conductive EAPs, e) Energy harvesting, are briefly discussed.
