Air pollution biomonitoring in households of a São Paulo's district: relationship between morbidities, acumulation of trace elements and mutagenic damage in Tradescantia pallida

Abstract

The high level of pollutants in the atmosphere of São Paulo generates a serious threat to quality of life of its inhabitants. The proximity to pollution sources and practices such as smoking influence the quality of indoor air, being potentially harmful to health. The use of biomarkers has shown the impacts of pollution on living things, including plants of the genus Tradescatia. This study aims to assess the response of bioindicators T. pallida automotive air pollution and tobacco smoke in indoor and outdoor residential, relating it to pregnancy outcomes, perinatal morbidity and data of all residents of the homes studied. To this end, the exhibition will be made of the biomarkers in and out of 40 homes through a sortition, a health district in the southeastern region of São Paulo. The exposure time will be six months, with monthly collections of flowers and leaves for analysis. Tests will be used for quantification of micronuclei in tetrads of Tradescantia (Trad-MCN) and analysis of foliar accumulation of heavy metals by XRF.Also be measured levels of NO2 and PM 2.5 in residences studied. For the collection of morbidity data, a questionnaire will be applied in each household. A study of biomonitoring able indoor environment and chart a positive correlation with events such monitoring family health resident may be of high importance and impact to encourage the use of plant bioindicators for monitoring air quality.
