RISK ASSESSMENT OF COMMONLY USED MAJOR PESTICIDES IN TOMATO AND PURITY ANALYSIS OF CARBOFURAN

Abstract

The aim of the present study was risk assessment that is hazard clianieteriz.ation and human exposure assessment of chemical Iv treated tomato available in dilThrent areas of Bangladesh and also to conduct purity analysis of carboluran. a frequently used pesticide by the liiriners in tomato field. To do the risk assessment prinianly a list ol available pesticides iii three dilkrent region of Bangladesh Nly mensingh. Narshindgdi and Jessore) was prepared by field visit and stirs cv. Secondarily to determine the potential health risks associated ith the exposures to these pesticides a scenario based on MSDS (material saft data sheet) evaluation was 2ivcn. Moreover. A Dl (acceptable (faily intake). M RI ( inaximuni residue level) and RI]) (reference (lose) value of' agro-clienticals ere also used which werc refirred by different organizations like WI 10. EPA.

All the pesticides available in the markets were Ilitind as authorized pesticides and none of them were fhund to be extremely hzwardotis according to the WI 10 recommended classi lication except carboluran. Iherefore to lind out present quality status of carbofliran (5(i) products available in market. purity analysis of randomly chosen thirteen samples was done by (K '-El!). Among them the highest concentration was found 6.82%. No carbofuran content vas found in Iwo samples. Most accurate concentration was 5.04%. The present stud indicates that there is a high chance to have residual effects of pesticides in tomato as a result of prehanest or posiharvest application. Most of the farmers do not know about health risk issue of using agro-chemicals. It is important to aware the farmers to follow the recommended close ol' registered pesticides and the consumers to proper handling and processing of tomato fOr saI consumption. In lorniation on health risk, exposure assessment was also highlighted for public awareness. Suggestions were provided on the handling and processing such as washing. cooking. boiling, packing. storage etc. for the sakt of the consumers. her words: Pesticide residue. survey. \ISDS. WHO.
