[High frequency hearing among rural workers exposed to pesticides].

Pesticides may cause a number of health problems and are considered oto-agressive agents. The objective of this study was to investigate the high frequency hearing characteristics of workers both with and without exposure to pesticides, that presented normal conventional audiometry. It involved a cross-sectional study with 87 workers, of both genders, between 19 and 59 years, with formal or informal jobs and some of whom worked with family agriculture, either using pesticides or not, who had taken High-Frequency Audiometry tests.

The hearing of rural workers exposed to noise and pesticides.

n work environments, different physical and chemical agents that may pose a risk to workers' hearing health coexist. In this context, occupational hearing loss stands out. It has mostly been attributed to only noise exposure, although there are other agents, that is, pesticides that might contribute to occupational hearing loss.

[Hearing care and quality of life among workers exposed to pesticides].

The objective of this study was to determine the relationship between exposure to pesticides and the occurrence of hearing loss among rural workers of Povoado Colônia Treze, Lagarto, State of Sergipe, Brazil. A total of 351 adult workers aged 18 to 59 years were selected, with current or past work activity in rural areas, with or without use of pesticides. The hearing evaluation included a form to record air-borne tonal thresholds using normality criteria recommended by Merluzzi 1979.
