Resumo
Particulate matter is an air pollutant that harms the health of humans, animals and plants, affects the climate and causes annoyance when settled on objects, materials and surfaces of common use. In metropolitan areas, particulate matter is originated mainly from industrial sources, carriers, soil suspension and construction sources by means of which the wind effects (direction and speed) promote the dispersion and sedimentation of the particles. This thesis investigates and evaluates the perception of annoyance caused by particulate matter in metropolitan and industrialized regions in order to identify the determinants of the perceived annoyance and its relation to the levels of particulate matter (PM10, PTS and Settled Particles). Data were collected through surveys conducted face-to-face and by telephone in the period 2011-2014 as well as concentration data of the measured pollutants in fixed stations monitoring air quality. Data were analysed through the application of multivariate statistical techniques, named multiple correspondence analysis, principal component analysis and both multiple and simple logistic regression. The results showed that approximately 90% of respondents reported being annoyed by air pollution, mainly by dust. Generally, the variables listed as determinants of annoyance are: importance of air quality, industrial risk perception, perception of pollution, occurrence of health problems, gender, occupation and age. The exposure versus response analysis showed that there was a significant relationship between the perception of annoyance (reported by respondents) and particulate matter concentration levels (PM10, PTS and Settled Particles). This work contributes scientifically and socially in order to provide guidelines for setting a standard of air quality despite of the annoyance caused by settled particles in the area of Greater Vitoria (Brazil). Finally, by the analysis of the combined effect of pollutants, estimated values for the relative risk of annoyance showed that an increase in the particle deposition rate contributes significantly to increasing the risk of annoyance.
