Identification of organochlorine insecticide contamination on shallots land in Nganjuk Regency, East Java Province, Indonesia

Abstract

The high and excessive use of pesticides is reported to have contamination shallot agriculture in Nganjuk Regency, East Java Province, Indonesia. Information on the presence of organochlorine residues needs to be carried out in the context of controlling environmental contamination as a form of implementing a national food security and security program. The purpose of this study was to identify organochlorine residues in shallot land in Nganjuk Regency. Soil samples from the field were taken in March 2020. Soil samples were taken at random diagonally on a stretch of shallot agriculture. Each overlay represents a sampling point. Organochlorine residue analysis was carried out at the Integrated Laboratory, Indonesian Agricultural Environment Research Institute (IAERI) using the QuECheRS method. The results showed that the residual of the organochlorine active ingredient of Endosulfan reaches 0.1066 to 0.1646 mg kg−1, Dieldrin reaches 0.181 mg kg−1 and Endrin reaches 0.2249 mg kg−1. These residual numbers have exceeded the MRLs requirements approximately 0.0085 mg kg−1 (Endosulfan), 0.00290 mg kg−1 (Dieldrin) and 0.0075 mg kg−1 (Endrin). These results showed that pollute agricultural land need to get priority on land remediation for sustainable agriculture.
