Abstract
In Iran, organochlorine insecticides such as lindane are used for agriculture purpose, in rice-field to destroy the pests. Due to high stability and long life, lindane can remain in rice crop and creates health problem for human after eating rice. Due to the rate of consumption of this group of pesticides in Mazandaran province, Iran, a sectional inspection was performed at Tarom rice crop of Sari and Neka cities. This pesticide was drew out sampling rice of the different regions of these cities with using organic solvent N-hexane, then examined with gas chromatography. The results showed that nearly all samples have the residues of this lindane at ppb level which is non toxic but continuoue use may cause health problems such as liver disorder or gastrointestinal cancer.
