A qualidade de vida de uma população está diretamente relacionada com a infraestrutura urbana em que a mesma está inserida. Nesse sentido, o objetivo do estudo foi avaliar a saúde pública da área urbana do município de Tucuruí no Paraná, sob o ponto de vista das condições do saneamento ambiental e a composição de um sistema com menor quantidade de variáveis para discriminar áreas com distintos níveis sanitário-ambientais, e relacionar esses indicadores com a ocorrência de agravos à saúde nessas áreas. O município de Tucuruí foi selecionado para a área de estudo devido à deficiência de sua infraestrutura sanitária, alta taxa de crescimento da população, e a forte incidência de doenças tropicais relacionadas diretamente com as condições sanitárias.
In recent years, wetlands have received increasing attention in environmental engineering. Both natural and constructed wetland systems are now being used to treat a wide range of industrial, urban, and agricultural effluents. In the present study, we measured the heavy metal uptake of a wetland area in Brazil that receives runoff water from runways and paved areas. We analyzed the water, sediments, and emergent macrophytes and compared the data with the results of other studies of the retention of pollutants by wetlands. We also determined the heavy metal accumulation by the dominant macrophyte using transfer coefficients to determine metal transfer among sediments, roots, and leaves. We found that although the wetland removed significant amounts of pollutants from the airport's drainage water through sedimentation, precipitation, and uptake by plants, additional work must be done to increase water retention times in the wetland to improve the wetland's ability to immobilize pollutants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
