Avaliação da qualidade do ar através da dispersão espacial de NO2, SO2 e O3 no município de São Gonçalo do Amarante (CE).

Abstract

Faced with the process of globalization, the demand for services and products has increased exponentially in recent centuries, promoting changes in the production system, mainly changing its scale. The industries currently produce as final products of their process some atmospheric pollutants, such as analytes under study, nitrogen dioxide, sulfur dioxide. In addition, according to secondary reactions, these compounds at low altitude promote the production of tropospheric ozone, leading to possible damage to human health. In the present study, these compounds were quantified as to their concentration according to the exposure of 40 passive samplers in the municipality of. In a period of 15 days during two campaigns between July and August, September and October. The passive sampling performed corresponds to the distribution of samplers made in the laboratory with the purpose of gas capture by gas diffusion and selective chemical reactions. With the concentrations of these pollutants, it was possible to elaborate maps of the spatial distribution of these pollutants, relating to meteorological conditions recorded through a mobile meteorological station distributed in the sampling network and of relief and topography conditions. With this data it is possible to infer about the dynamics of these compounds in the atmosphere and the influence of the Industrial Complex and Port of Pecém (CIPP) on the concentrations of these gases according to the distance gradient of the project. In addition, it is possible to observe how the behavior of the gases occurs in the nuclei of urban densification, related to possible damage to human health.
