Avaliação dos parâmetros sanguíneos e ventilatórios de trabalhadores rurais expostos a agrotóxicos

Abstract

Agrochemicals are used in agriculture to increase crop yields, however the inadequate use of these products has become a threat to the public health, especially for rural workers, due to misinformation about their harmfulness. Thus, the present study aimed to evaluate the levels of intoxication of rural workers by pesticides throught the quantification of blood biomarkers and the activity of respiratory capacity. The chemical groups of the pesticides studied were organophosphates, carbamates and triazoles. The mean age of the exposed population was 39.95 years. The average contact time with pesticides in the exposed group was 17.87 years. A cross-sectional study was carried out with N = 130 rural workers divided into n = 65 (EXPECTED GROUP) and n = 65 (CONTROL GROUP) who did not have direct contact with pesticides in the last 12 months. To obtain this information, an epidemiological-occupational questionnaire was applied. The biological markers analysis was performed through blood collection. Regarding the evaluation of pulmonary function and capacity were performed through Spirometry and Manovacuometry devices. It is believed that the measured exposure measures are significantly associated with loss of pulmonary function, presenting a prevalence of obstructive and / or restrictive ventilatory disorders. These findings could indicate the vulnerability of the respiratory system to these contaminants, especially when not used to protective measures in the use of these substances, causing a loss of the quality of life of rural workers exposed to agrochemicals. In view of this scenario, it would be necessary to develop a public health program to monitor the work environment and monitor these workers.
