DALBO, Juliana; FILGUEIRAS, Lívia Alves  e  MENDES, Anderson Nogueira. Effects of pesticides on rural workers: haematological parameters and symptomalogical reports. Ciênc. saúde coletiva [online]. 2019, vol.24, n.7, pp.2569-2582.  Epub 22-Jul-2019. ISSN 1413-8123.  http://dx.doi.org/10.1590/1413-81232018247.19282017.

Exposure to pesticides by the rural population is increasing worldwide. Pesticides can induce the development of different diseases such as cancer and diseases of the central nervous system. This study analysed the clinical symptoms and haematological changes of a rural population in Conceição do Castelo, Espirito Santo, Brazil. For evaluation of symptomatology exposure to pesticides, 142 rural workers were interviewed. Of these, 22 workers were selected for haematological tests randomly as to evaluate haematological changes during the period of exposure to pesticides. Haematological analyses showed that erythrocytes, haemoglobin, haematocrit, mean corpuscular (VCM) volume, mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC) are in accordance with the reference intervals in haematology. Variations in the concentrations of rods and neutrophils indicates that exposure to pesticides increases the amount of those cells. Haematological disorders in rural workers exposed to pesticides can be correlated with reported symptoms. The results described in this study are relevant to the health public and reinforce the concern about the indiscriminate use of pesticides.
