“…55 As concentrações de PTS foram significativamente maiores (p < 0,05) nos meses da estação seca em relação aos meses da estação chuvosa, que apresentaram médias de 118,06 µg m -3 e 59,35 µg m -3 , respectivamente. Esse resultado está de acordo com evidências científicas sobre a interferência da sazonalidade na concentração de partículas atmosféricas, [56][57][58] que pode ter se dado devido à diferença nos níveis de pluviosidade entre as estações, que foi de 55,80 mm e 414,20 mm (Tabela 1) nos períodos seco e chuvoso, respectivamente. 39 As condições pluviométricas nos dias em que as coletas foram realizadas também se apresentaram dentro do esperado para as estações e dessa maneira não houve grandes variações nas concentrações de PTS na atmosfera, durante a amostragem (Tabela 1).…”

SPATIAL AND SEASONAL EVALUATION OF CONCENTRATIONS OF TOTAL SUSPENDED PARTICLES AND ASSOCIATED METALLIC ELEMENTS IN THE AIR OF A SOUTHEASTERN BRAZILIAN CITY. The present study evaluated the concentrations of Total Suspended Particles (TSP) and associated metals in three distinct regions of Ribeirão Preto city (Center City, Campus and Airport) in the dry and rainy seasons. There were no significant differences (p < 0.05) in TSP and metals concentrations between the sampling sites, except for Cu, Cr and Zn. Seasonal variation was observed for TSP and the following associated metals: As, Be, Cu, Mn, Ni, Pb, Sn and V, being the highest concentrations observed in the dry period. The TSP concentrations did not exceed the air quality standards in São Paulo state, but these can cause harm to the population health, especially in the dry season. Cadmium was the only element that exceeded the WHO air quality guidelines in two consecutive samplings in the Center City and the Airport during the dry season. In this way, preventive measures should be taken through public policies to improve local air quality control and reduce the health risks to the population.

“…As the results show, the particulate-bound PAHs in this study were lower compared to the PAH levels measured in other cities around the world. Cazier et al (2016) found that the concentration of total PM 2.5 -bound PAHs measured in Northern France ranged from 0.2 to 437.7 ng/m 3 . For the two periods, the levels of concentration of PAHs present in the particles collected under urban-industrial influences were higher than those for particles collected under rural influences (Cazier et al, 2016).…”

Exposure to air pollution is associated with increased morbidity and mortality. Once the fine atmospheric particulate matter (FP) is inhaled, some of its compounds can pass through the lungs and reach the bloodstream where they can come into contact with immune cells. Exposure to FP particularly affects sensitive populations such as the elderly. Aging affects the immune system, making the elderly more vulnerable.The project aims to determine the effects of FP exposure on human T cells while looking for biomarkers associated with exposure. Blood samples from 95 healthy subjects in three different age groups (20-30, 45-55 and 70-85 years) were collected to determine a potential age effect. T lymphocytes were isolated to be exposed ex vivo for 72 hours to 45 μg/mL of FP collected in Dunkirk and chemically characterized. Overexpression of the CYP1A1, CYP1B1 and CYP2S1 genes was therefore measured after exposure of the T cells to FP. These genes code for enzymes known to be involved in the metabolic activation of organic compounds such as polycyclic aromatic hydrocarbons detected in the FP sample. T-cell profiling allowed us to suggest a mixed T-helper 1/2 profile caused by exposure to FP. With regard to the influence of age, we have observed differences in the expression of certain genes, as well as an increase in interleukin-4 and -13 concentrations in the elderly. These results showed that exposure of T lymphocytes to FP causes effects on both transcriptomic and cytokine secretion levels.
