Atmospheric dispersion study of air pollutant pm10 generated in aluminum recycling

Despite all the progress made in reducing air pollutant emissions over the last decades, air pollution still represents one of the major environmental problems in urban centers. Air quality can be assessed at local, regional, national and international levels by estimating emissions, using mathematical models and measuring the environmental concentrations of major pollutants using physicochemical methods. Through such measures, it is possible to verify whether standards and limit values for air pollutant concentrations, established or recommended by national governments. Possible effects depend not only on the concentration and duration of the impact, but also on many different factors such as climate, nutritional status, predisposition, age, the simultaneous impact of other pollutants and others that play an important role. From these considerations, the objective of this work is to conduct a study of the concentrations of isokinetic monitored atmospheric pollutants at the chimney outlet, the production process of the Alutech Aluminio LTDA Company, with the pollutants monitored at the stations of the Duque City Quality Telemetric Network. de Caxias, correlating them with the meteorological variables, proposing control measures and procedures to mitigate the impacts on the surrounding population. Crossing this data will allow modeling of each source, dispersion, coverage and distance from the source. It will be possible to analyze the behavior of the dispersion plumes with the variation of the source height, seeking the minimum variation for better dispersion of the pollutants. It will be possible to plan actions on days of thermal inversion, such as feed ratio / production capacity, retention time and fugitive emissions from the control system, so that there is better dispersion of pollutants.
