Este trabalho apresenta valores da variação de concentração, caracterização elementar e avaliação da toxidade in vitro no material particulado 10 μm (MP10) coletado em dois sítios na área urbana de Catalão-GO. O período amostrado foi entre 05/08/17 a 28/03/18. Os valores de concentração de MP10 estavam em conformidade com a legislação do CONAMA. A espectrometria de fluorescência de raios X identificou a presença majoritária de ferro e menores quantidades de fósforo e enxofre, caracterizando o MP10como resultado da ressuspenção de solo, emissão veicular e emissões do setor industrial. No estudo de toxidade verificou-se que o MP10 não inibiu o desenvolvimento de culturas bacterianas. Referências 1. Queiroz, P. G. M.; Jacomino, V. M. F.; Menezes, M. A.

The Individual

The oxidant air pollutants, ozone and peroxyacetyl nitrate, are produced in the atmosphere through the interaction of light with nitrogen oxides and gaseous hydrocarbons. These oxidants are phytotoxicants and are known to deleteriously affect plant growth, physiology, and biochemistry. In many instances they induce changes which lead to the death of cells, tissues, organs, and frequently the entire plant. The most obvious damage and biochemical changes are generally observed with leaves.Electron microscopic examination of leaves from bean (Phaseolus vulgaris L.) tobacco (Nicotiana tabacum L.) and cotton (Gossipyum hirsutum L.) fumigated for .5 to 2 hours with 0.3 -1 ppm of the individual oxidants revealed that changes in the ultrastructure of the cells occurred in a sequential fashion with time following the fumigation period. Although occasional cells showed severe damage immediately after fumigation, the most obvious change was an enhanced clarity of the cell membranes.

Individual Particle Analysis

Individual-particle analysis is well established as an alternative to bulk analysis of airborne particulates. It yields size and chemical data on a particle-by-particle basis, information that is critical in predicting the behavior of air pollutants. Individual-particle analysis is especially important for particles with diameter < 1 μm, because particles in this size range have a disproportionately large effect on atmospheric visibility and health.
