Pesticide residues and their detection techniques in foods using sensors- a review

The use of pesticides in agricultural produce is continuously increasing and it raises the question of whether the food is safe or not. Only 0.1% of the sprayed pesticide reaches its target and the rest acts as a contaminant in soil and the environment, thus contaminating the future foods as well. The pesticide residue management is gaining attention as pesticide poisoning account for more than 3.5% of total deaths. The use of pesticides needs to be checked and applied in a controlled manner. Easy and rapid methods for the quantification of pesticides in foods need to be developed. In the present review, details about pesticides have been described in the first part. Secondly, the techniques and recent developments for the detection of pesticides have been summarized and finally, the emerging challenges and future perspectives for pesticide handling has been discussed with special emphasis on the use of Nano-sensors for pesticide detection.
