“…The air quality monitoring network in Brazil is limited in terms of number of parameters monitored, territorial coverage and representativeness in measurements (Siciliano et al 2019). Data available for the cities of Rio de Janeiro and São Paulo are obtained by the environmental agencies of the state of São Paulo (CETESB 2020), the state of Rio de Janeiro (INEA 2020) and the city of Rio de Janeiro (SMAC 2020), using standard methods and equipment according to Brazilian legislation (CONAMA 2018).…”

As COVID-19 spread all over the world, most of the countries adopted some kind of restrictions to avoid the collapse of health systems. In Brazil, São Paulo and Rio the Janeiro, the two most populated cities in the country, were the first to determine social distancing. In this study, the impact of the social distancing measures on the concentrations of the three main primary air pollutants (PM 10 , NO 2 and CO) was analyzed. CO levels showed the most significant reductions (up to 100%) since it is related to light-duty vehicular emissions. NO 2 also showed reductions (9.1%-41.8%) while PM 10 levels were only reduced in the 1st lockdown week. The decrease of pollutants was not directly proportional to the vehicular flux reduction, because it depends on other factors such as the transport of air masses from industrial and rural areas. The differences observed can be explained considering the fleet characteristics in the two cities and the response of the population to the social distancing recommendations.

“…Particulate matter up to 2.5 µm (PM 2.5) and total suspended particulate matter (PTS) were collected by Pall Life Sciences glass ber membrane lters with 24-hour cycles, using a large volume sampler for determination of the concentration of respirable particles (up to 2.5 µm) in ambient air (AGV MP2.5), with separation head and volumetric ow controller (CVV), and a large volume sampler (AGV) for the determination the concentration of PTS in ambient air, both manufactured by Energica. The sampling method was carried out by the rules for sample collection (EPA 2006) and in accordance with the National Environment Council (CONAMA) (Siciliano et al 2020).…”

The emission of residues has contributed immensely to the fact that man is susceptible and exposed to toxic chemical products, among them, arsenic. One of the main anthropic sources of arsenic in the world is mining, which can contribute to the contamination of soil, water, air, and food. An example of environmental arsenic contamination in Brazil occurs in the city of Paracatu - MG, due to the operation of a gold mine. Thus, the objectives of this study were: (i) to assess the physical-chemical parameters and the concentration of arsenic in samples of superficial fresh water (sub-basin of the Paracatu River), and soil samples, during winter and summer; (ii) evaluate the arsenic concentration in samples of particulate matter; (iii) determine the concentration and species of As in biological samples and (iiii) evaluate the toxicity of surface waters using the Allium cepa test. There was no change in the physical-chemical parameters. The water samples collected during the winter and all soil samples showed values of As above those allowed by organs regulatory agencies. The values of As in the particulate material showed great variations between the regions under study but were within the limit established by the ATSDR for urban areas. Inorganic and organic As was found above the limit allowed in biological samples The analysis of water toxicity by the Allium cepa test indicated the presence of cytotoxic and genotoxic compounds, demonstrating a great risk for the population exposed to the waters of the Rico stream.

“…Mexico (12 μg/m 3 ) and Canada (8.8 μg/m 3 ) have also defined relatively low standards for the annual average PM 2.5 concentration [ 31 , 32 ]. In South America, Brazil determined the final standards of PM 2.5 and PM 10 in 2018, which 24-h and annual average are the same as those prescribed by WHO [ 33 ]. However, Chile had relatively higher standards of PM 2.5 (24-h: 50 μg/m 3 ; annual: 20 μg/m 3 ) than these above countries [ 34 ].…”

Particulate matter (PM) is a major factor contributing to air quality deterioration that enters the atmosphere as a consequence of various natural and anthropogenic activities. In PM, polycyclic aromatic hydrocarbons (PAHs) represent a class of organic chemicals with at least two aromatic rings that are mainly directly emitted via the incomplete combustion of various organic materials. Numerous toxicological and epidemiological studies have proven adverse links between exposure to particulate matter-bound (PM-bound) PAHs and human health due to their carcinogenicity and mutagenicity. Among human exposure routes, inhalation is the main pathway regarding PM-bound PAHs in the atmosphere. Moreover, the concentrations of PM-bound PAHs differ among people, microenvironments and areas. Hence, understanding the behaviour of PM-bound PAHs in the atmosphere is crucial. However, because current techniques hardly monitor PAHs in real-time, timely feedback on PAHs including the characteristics of their concentration and composition, is not obtained via real-time analysis methods. Therefore, in this review, we summarize personal exposure, and indoor and outdoor PM-bound PAH concentrations for different participants, spaces, and cities worldwide in recent years. The main aims are to clarify the characteristics of PM-bound PAHs under different exposure conditions, in addition to the health effects and assessment methods of PAHs.
