We analyzed the incidence of structural and numerical chromosomal aberrations (CAs) in workers of a plantation of flowers located in Quito; Ecuador, in South America. This study included 41 individual occupationally exposed to 27 pesticides, some of which are restricted in many countries and are classified as extremely toxic by the World Health Organization; among these are aldicarb and fenamiphos. The same number of individuals of the same age, sex, and geographic area were selected as controls. Workers exposed to these pesticides showed an increase frequency of CA compared with ... <0.001). We conclude that screening for CA is ,an adequate biomarker for evaluating and detecting genotoxicity resulting from exposure to pesticides, Levels of erythrocyte acetylcholinesterase were also determined as a complementary metabolic study. Levels below the optimal (>
