Resumen:
The use of pesticides undeniably comes with some risks. It is understood
that people who work with pesticides typically have much higher
exposure than general public. The present work evaluated the prevalence
of adverse events occurring during occupational exposure as an
estimation of health impact. Also associations with several demographic
characteristics, lifetime exposure years, working practices and
protection level, considering a personal protection equipment (PPE)
index, were investigated. Our results shown that the study population is
relatively young (34.9±11.04 y); 71% have up to 10 years of exposure
and 80% are under 45 years of age, being 11.8% illiterate or with
incomplete primary school. PPE is not adequate used in around 70% of the
workers. Agrochemical prescription, indicated by an agricultural
engineer, is only used by 38% of workers and the percentage of use of
modern technologies (such as crop sprayers equipped with cabs and
activated charcoal filter) is low. Forty four percent answered to have
irritative symptoms (skin, eyes, nausea and vomiting) frequently, 35%
requiring medical consultation and 5.4% hospitalisation. Other symptoms
such as headache, tiredness, nervousness or depression were also
reported. The lifetime exposure is associated with irritative signs,
like headache, nervousness and depression and, the low protection, with
irritative eye symptoms, headache, nervousness and depression. The use
of modern application technologies was negatively associated with skin
irritation. Low levels of PPE use, lifetime exposure and lack of safe
environments with appropriate technologies, involves higher levels of
cumulative exposure, resulting in greater negative impact on their
health.
