Abstract

MALAGON-ROJAS, Jeadran N.; GARROTE-WILCHES, Carolina Fernanda  and  VARONA, Marcela. A debt from the past: effects of organochlorines in workers of vector control program - Colombia. Rev. Univ. Ind. Santander. Salud [online]. 2014, vol.46, n.3, pp.227-235. ISSN 0121-0807.

Introduction: It is assumed that in Colombia organochlorides are not used due to the ratification of the Stockholm Convention and the Rotterdam Convention, forbidding the use of those substances. Objective: To evaluate exposure to organochloride pesticides used in the working population of the vector control program in Colombia, 2013. Methods: A descriptive cross-sectional study was performed in the group of workers from the vector-borne disease management program. To all participants were applied a standardized questionnaire to collect sociodemographic, occupational, clinical and toxicological variables. Thirteen organochloride levels in serum were measured by gas chromatography at the National Institute of Health of Colombia. Results: The report show using of organochloride insecticides in the 39.1%. One hundred percent of the workers who used organochlorides reported use of DDT. 7,5% reported use of aldrin. One hundred percent or the workers referred the absence of elements of personal protection when implementing chlorinated compounds. Organochlorides with higher levels were 4,4- DDT y α -HCH. The most common symptoms were: headache 28.7%, dizziness 29.9%, decreased strength in upper limbs 17.2% and neuropsychiatric symptoms 24%. An association between occupational exposure to DDT and neuropsychiatric symptoms were found. Conclusions: The average of DDT in blood of workers in Colombia is higher than those reported in the literature. Findings of neuropsychiatric symptoms and occupational exposure to organochloride are consistent with literature reports.
