“…In contribution to our result, cold seasons are associated with high pollution episodes, being the highest levels of pollutants occurring in winter [30] [31] [32] [33]. During low temperature and winter days, thermal inversion is commonly observed, and, in this period, the concentration of pollutants tends to be higher, leading to a poor air quality environment [34]. Also, parks could intensify low temperature and contribute to pollution concentration due to the shading and cooling effect caused by trees that act as barrier of pollutants [35] [36].…”

Traffic-related air pollution is an alarming source of pollutants exposure and consequently to the development of several adverse health effects. Otherwise, green spaces are reported to improve health status. Although, in an urban scenario most of these areas are located near air pollutants sources, as vehicle fleet. Thus, the aim of the present study was to determine, during one year, the levels of nitrogen dioxide (NO 2) and ozone (O 3) in the main parks from Porto Alegre-Brazil. This study focused on three urban parks: Germânia, Moinhos de Vento and Marinha do Brasil Park. Nitrogen dioxide and ozone measurements were accessed by passive monitoring in four campaigns including all seasons and performed at distances of 0 m, 15 m, 30 m, 45 m, 60 m and 75 m from the main road at each park. NO 2 and O 3 concentration among the parks was not different (p > 0.05), as well as the mean concentration of NO 2 and O 3 of all parks in the six sites did not differ (p > 0.05). However, season 1 and 3 showed increased NO 2 and O 3 concentration. Temperature were decreased in season 1 and 3 (p < 0.05), while humidity, pressure and insolation showed no difference among seasons (p > 0.05). Traffic flow was higher in Moinhos de Vento Park and Marinha do Brasil Park compared to Germânia Park (p < 0.05). Overall, the seasonal variation could directly interfere in NO 2 and O 3 concentration in urban parks from Porto Alegre.

“…At these sites, significantly higher PM 2.5 levels occurred during autumn and winter. This behavior is often associated with higher levels of combustion for central heating (domestic and industrial) and stronger thermal inversion conditions, which cause an accumulation of air pollutants in the lower layers of the atmosphere and are much stronger and frequent in colder months [33][34][35][36]. At both sites, a well-defined U-shaped profile is even observed during the period from March to October.…”

Particulate matter with an aerodynamic diameter of less than 2.5 µm (PM2.5) is associated with adverse effects on human health (e.g., fatal cardiovascular and respiratory diseases), and environmental concerns (e.g., visibility impairment and damage in ecosystems). This study aimed to evaluate temporal and spatial trends and behaviors of PM2.5 concentrations in different European locations. Statistical threshold models using Artificial Neural Networks (ANN) defined by Genetic Algorithms (GA) were also applied for an urban centre site in Istanbul, to evaluate the influence of meteorological variables and PM10 concentrations on PM2.5 concentrations. Lower PM2.5 concentrations were observed in northern Europe. The highest values were found at traffic-related sites. PM2.5 concentrations were usually higher during the winter and tended to present strong increases during rush hours. PM2.5/PM10 ratios were slightly higher at background sites and the lower values were found in northern Europe (Helsinki and Stockholm). Ratios were usually higher during cold months and during the night. The statistical model (ANN + GA) allowed evaluating the combined effect of different explanatory variables (temperature, wind speed, relative humidity, air pressure and PM10 concentrations) on PM2.5 concentrations, under different regimes defined by relative humidity (threshold value of 79.1%). Important information about the temporal and spatial trends and behaviors related to PM2.5 concentrations in different European locations was developed.

“…Air pollution has detrimental impacts on human health (Liu et al, 2019, b;Khaniabadi et al 2019;Gu et al 2019) with health effects ranging from cardiovascular diseases (CVD) (Curto et al 2019), respiratory diseases (RD) (Croft et al 2019), and mortality (Chen et al 2019). The increase in the levels of ambient air pollution is associated with increased adverse health effects (Trinh et al 2019;Chen et al 2019); and there is documented evidence that decreased exposure to air pollution decreases population mortality and morbidity and it increases life expectancy (Brønnum-Hansen, et al 2018;Hoffmann 2019). Increases in air pollution levels are associated with increases in health effects of susceptible groups such as children, the elderly, pregnant women, and people with chronic diseases (Stieb et al 2019;Koman et al 2018;Hooper et al 2018).…”

Studies have confirmed that adverse human health effects that are associated with exposure to air pollution may differ depending on other factors such as age, gender, environmental conditions, and socio-economic factors. This study was conducted to assess the association between ambient air pollution and cause-specific mortality in the three big cities in South Africa and to determine the susceptible groups thereof. Cause-specific mortality data for all ages and PM10, NO2, and SO2 in Cape Town, Durban, and Johannesburg for the period from 1 January 2006 to 31 December 2010 were obtained. Statistical analyses were done to estimate the associations between air pollutants and cause-specific mortality. Susceptibility was therefore investigated in stratified analyses by sex and age (≥60 years) and environmental conditions (heat and cold) followed by models with interaction terms. Our estimates showed independent associations between these air pollutants, environmental conditions, and susceptible groups.
