The utilization of biomass for power generation has become more prevalent globally. To survey the status of evidence concerning resulting health impacts and to depict potential research needs, a scoping-review was conducted. Biomass life cycle phases of interest were the conversion and combustion phases. Studies from occupational and residential settings were considered. The scoping review was conducted systematically, comprising an extensive literature search, a guided screening process, in-duplicate data extraction, and critical appraisal. Two reviewers executed most review steps. Nine articles of relevance were identified. In occupational settings of biomass plants, exposure to endotoxins and fungi might be associated with respiratory disorders. An accidental leakage of hydrogen sulfide in biogas plants may lead to fatalities or severe health impacts. Living near biomass power plants (and the accompanied odorous air pollution) may result in an increased risk for several symptoms and odor annoyance, mediated by perception about air pollution or an evaluation of a resulting health risk. The methodological quality of included studies varied a lot. Overall, the body of evidence on the topic is sparse and future high-quality research is strongly recommended.

Além disso, a existência de associação entre perdas auditivas e outras variáveis (idade, tempo de trabalho na função, exposição extra-ocupacional ao ruído, uso de equipamento de proteção individual e queixa de zumbido) foi verificada. Utilizaram-se dados de 73 Operadores de Tráfego, previamente submetidos a exames audiométricos e a um questionário, disponíveis em banco de dados do Serviço de Saúde Ocupacional da Universidade de São Paulo. Os resultados sugerem que a exposição extra-ocupacional a ruído, mas não a exposição ocupacional a ruído urbano, tem efeito no aparecimento das perdas auditivas.</p></span></span>
