MALDONADO ORTEGA, Valeria; OCHOA FUENTES, Yisa María e CERNA CHAVEZ, Ernesto. Determination of organophosphate pesticides to pest control workers of the state of Coahuila, México. Horiz. sanitario [online]. 2020, vol.19, n.2, pp.217-222. Epub 13-Nov-2020. ISSN 2007-7459. https://doi.org/10.19136/hs.a19n2.3640.
Object
To determine the level of organophosphorus pesticides in urine samples, in order to propose the appropriate use of safety measures to reduce occupational hazards caused by constant exposure to these products.
Materials and methods
A colorimetric technique was used to determine four organophosphorus pesticides: methamidophos, malathion, chlorpyrifos and naled, in urine samples collected in the state of Coahuila. A visible ultraviolet spectrophotometer was used for analysis.
Results
The data obtained in this investigation showed that the four products analyzed were present in the urine samples, in a concentration range of 11.4 to 654.15 μl / ml.
Conclusions
Positive results were obtained in the sixteen urine samples, finding presence of the four organophosphorus pesticides studied, which could indicate a lack of use of safety measures in workers.
