The impact of involuntary exposure to pesticides was studied in a group of professional sprayers (S) (25 ± 5 years old) exposed to various agrochemicals for about 10 years. The results were compared with a group of non exposed people (C). S group showed hematological, renal, pancreatic and hepatic biomarkers within the reference values established for the general population, including cholinesterase activity. In spite of that, all the biochemical tests were statistically different compared to C. On the other hand, oxidative stress biomarkers (OSB) such as plasma tocopherol and the total reducing ability of plasma were significantly decreased, while protein carbonyls, thiobarbituric acid-reactive substances, total glutathione and the sum of nitrites and nitrates were increased in the exposed group. Results demonstrated that screening laboratory tests could not be fully sensitive in detecting sub-clinical exposure to pesticides, and also suggest that OSB could be validated and included in health surveillance protocols.
► We study a group of pesticide exposed workers (S) in comparison with non-exposed group (C).
► We analyze routine and oxidative stress biomarkers (OSB) in it efficiency to detect exposure effects.
► Routine laboratory tests are not fully sensitive in detecting sub-clinical effects.
► We suggest that OSB could be validated and included in health surveillance protocols.
► Efforts may be canalized to primary prevention and to increment the screening sensibility of the health checkup.
