This paper presents an analysis of the effects of the COVID-19 pandemic on the air quality of the Metropolitan Region of São Paulo (MRSP). The effects of social distancing are still recent in the society; however, it was possible to observe patterns of environmental changes in places that had adhered transportation measures to combat the spread of the coronavirus. Thus, from the analysis of the traffic volumes made on some of the main access highways to the MRSP, as well as the monitoring of the levels of fine particulate matter (PM2.5), carbon monoxide (CO) and nitrogen dioxide (NO2), directly linked to atmospheric emissions from motor vehicles–which make up about 95% of air polluting agents in the region in different locations–we showed relationships between the improvement in air quality and the decrease in vehicles that access the MRSP. To improve the data analysis, therefore, the isolation index parameter was evaluated to provide daily information on the percentage of citizens in each municipality of the state that was effectively practicing social distancing. The intersection of these groups of data determined that the COVID-19 pandemic reduced the volume of vehicles on the highways by up to 50% of what it was in 2019, with the subsequent recovery of the traffic volume, even surpassing the values from the baseline year. Thus, the isolation index showed a decline of up to 20% between its implementation in March 2020 and December 2020. These data and the way they varied during 2020 allowed to observe an improvement of up to 50% in analyzed periods of the pollutants PM2.5, CO and NO2 in the MRSP. The main contribution of this study, alongside the synergistic use of data from different sources, was to perform traffic flow analysis separately for light and heavy duty vehicles (LDVs and HDVs). The relationships between traffic volume patterns and COVID-19 pollution were analyzed based on time series.

Possible Cause

On March 24, 2020, a partial lockdown was decreed in the state of São Paulo, Brazil, as a measure to hinder the spread of COVID-19, which consisted in prohibiting crowding and advising people to stay home, except for urgent or extremely necessary matters. Based on studies performed in other countries, this study aims to assess the impacts of the lockdown on the air quality of five cities in the state of São Paulo. Our study was conducted by using particulate matter and nitrogen dioxide as air quality indicators, and by correlating the contaminants concentrations with weather data. The results showed an increase in these contaminants in all cities within the first weeks after the lockdown compared with the weeks before the decree and with the same period in previous years. This result is inconsistent with the literature. Therefore, a secondary goal was set to investigate the possible cause (or causes) of such deterioration in air quality, which led to the increased number of wildfires. The anomalous dry weather favored the burning of vegetation in agricultural rural areas and in small, vegetated areas near the municipalities, and limited pollution scavenging by rainfall, both of which contributed to higher pollution concentration. We hypothesize the possible effects of worse air quality on the aggravation of COVID-19, but further research is necessary to obtain a complete assessment.

Objetivo: analisar as características sociodemográficas associadas à percepção da qualidade de vida de mulheres atendidas na atenção primária. Metodologia: estudo transversal, quantitativo, desenvolvido com 113 mulheres em uma unidade de saúde do interior de São Paulo. Utilizou-se um questionário sociodemográfico e a versão abreviada do instrumento de avaliação de qualidade de vida. Para análise dos dados, foram empreendidos testes de associação. Resultados: a maioria das participantes era de classes sociais menos favorecidas e apresentava boa percepção de qualidade de vida e saúde. Os fatores renda, escolaridade e idade foram os mais relevantes na associação com a qualidade de vida. Conclusão: Apesar de mencionarem boa qualidade de vida e saúde, foram identificados piores resultados nos domínios físicos, psicológicos e meio ambiente.  Os achados reforçam a necessidade de que as ações de saúde estejam contextualizadas aos aspectos sociais/territoriais e vinculadas a políticas mais amplas de redução da vulnerabilidade social. WOMEN'S QUALITY OF LIFE AND ASSOCIATED SOCIO DEMOGRAPHIC CHARACTERISTICSObjective: to analyze the sociodemographic characteristics associated to the perception of the quality of life of the women attended in the Primary Health Care. Methodology: this cross-sectional quantitative study was carried out with 113 women aged 20 to 65 years in a health unit in the interior of São Paulo. A sociodemographic questionnaire and the abbreviated version of the WHOQOL-bref quality of life assessment instrument were used. For data analysis, association tests were undertaken. Results: the majority of participants were from less favored social classes and had a good perception of quality of life and health. The factors income, schooling and age were the most relevant in the association with quality of life. Conclusion: in view of the sociodemographic characteristics associated with quality of life in the present study, it is emphasized that health actions should be linked to broader policies to reduce social vulnerability, enabling empowerment strategies and, above all, increasing women's access to education and income.Descriptors: Quality of Life; Health Centers; Social Vulnerability; Women; Primary Health Care.CALIDAD DE VIDA DE LAS MUJERES Y LAS CARACTERÍSTICAS SOCIODEMOGRÁFICAS ASSOCIADASObjetivo: analizar las características sociodemográficas asociadas a la percepción de la calidad de vida de mujeres que acuden a atención primaria.

Air pollution is one of the main environmental problems in large urban centers, affecting people’s health and impacting quality of life. The Metropolitan Area of São Paulo (MASP) presents frequent exceedances of air-quality standards in inhalable particulate matter (PM10), a consequence of pollutant emissions modulated by meteorological conditions. This study aims to identify and characterize PM10persistent exceedance events (PEE) inthe MASP between 2005 and 2017, relating them to meteorological conditions. The criteria used to select the events were: (i) events that occurred in at least 50% of the air-quality monitoring stations chosen for this study and, (ii) among the events that met the first criterion, those with a duration equal to or greater than five days, which correspond to the 80% percentile of the event duration distribution. A total 71 persistent episodes of exceedance were selected. The results show that the exceedance of PM10 lasted up to 14 consecutive days and was predominant in the austral winter, accompanied by an increase in maximum temperature (T), a decrease in wind speed (WS) and relative humidity (RH), and a wind direction predominantly from the northwest during the peak concentration of the pollutant. On average, a concentration increase of 60% was observed at the peak of the PEE.

The consumption of lamb meat in Brazil has increased in the last years but little information about the microbiological quality of this product is available. To evaluate the hygienic-sanitary conditions of lamb carcasses, the quantification of microorganism populations indicators (mesophiles and psychrotrophs; total and thermotolerant coliforms; Escherichia coli; moulds and yeasts) and the pathogenic microorganisms indentification (Salmonella sp. and Listeria spp.) were performed. A total of 60 lamb carcasses were sampled from one abattoir in São Paulo. Swab samples were collected from three points (forequarter, back and hindquarter) on the muscle surface after carcasses final washing. Statistical analysis consisted of descriptive evaluation of the results whose counts were grouped by intervals of microorganism populations. Counts ranged from 1.0 x 10¹ to 8.0 x 10(4) colony-forming unit cm-2 (CFU cm-2) for mesophiles; 1.0 x 10(0) to 4.4 x 10(4)CFU cm-2 for psychrotrophs; < 1.0 x 10(0) to 4.4 x 10(4)CFU cm-2 for moulds and yeasts; < 0.3 to > 32.0 most probable number/cm² (MPN cm-2) for total and thermotolerant coliforms and Escherichia coli. Salmonella sp. and Listeria spp. were not found in any of the carcasses. Most carcasses presented low counts for all microorganisms. Overall results may be explained by the small size of the industry where the study was taken. Results suggest that good microbiological quality lamb meat is possible to be obtained, but improvement in hygienic-sanitary conditions is still required.
