Objective

To establish hematotoxic alterations through clinical and paraclinical exploration in workers who are exposed to organophosphorus pesticides, carbamates and pyrethroids (OPCP) due to their work in production, packaging, distribution and fumigation processes in Cundinamarca-Colombia between 2016 and 2017.

Materials and Methods

A cross-sectional descriptive epidemiological study was carried out on a sample of 92 workers from six companies, mostly aged between 18 and 30 years, of which 61 % were males and 39 % females, and 71 % were workers in the operational area and 29 % in the administrative area. Univariate, bivariate and multivariate analyses were performed.

Results

Clinical exploration reported findings in 17 % of the sample group, of which only 2 % presented with erythrocyte cholinesterase outside the reference range. The values of hematological parameters such as peripheral blood smear (PBS) and complete blood count (CBC) were outside the range in 15 % and 47 % of the sample, respectively.

Discussion

The results suggest that there are hematological alterations in this group that could possibly be associated with chronic exposure to OPCP.
