Avaliação da qualidade do ar na cidade de Alegrete/RS utilizando biomonitoramento vegetal

Abstract

The concentration of material in the atmosphere directly affects air quality, causing consequences to the environment and human health, being associated with increased morbidity and mortality due to respiratory, cardiovascular, infectious diseases and lung cancer. Biomonitoring of air quality is a viable procedure for the control and improvement of air quality. Due to the lack of evaluation methods and oral reports of irritating white particulate matter in the city of Alegrete / RS, the objective of the present study was to evaluate the air quality in the city, using techniques such as biomonitoring by the micronucleus technique of Tradescantia pallida and the chemical accumulation in tree barks to investigate the air quality in the city. The Tradescantia pallida test showed no results either geographic or temporally. The chemical composition of MP accumulated in bark of trees indicated different sources emitting for the points studied.
