“…Children exposed to the highest level of MISR-derived PM 2.5 on average were −3.54% (95% CI: −6.24%, −0.49%) lower in FEV 1 compared to those exposed to the lowest level. In the same CHS cohort and during the same follow-up period, Franklin and Fruin [4] found a significant association between NO x on FVC when adjusted for traffic-related noise exposure. We found a similarly significant relationship between NO − 3 and FVC where an IQR increase in NO − 3 (0.64 µg/m 3 ) is associated with 53 mL decrease in FVC (95% CI: −98, −7).…”

“…Using mixed-effects models, we adjusted for study community with a random intercept and for biological characteristics such as age, gender, height, BMI, and race/ethnicity as fixed effects. Based on previous studies of the CHS, log transformation of FEV 1 and FVC as well as quadratic terms for height and BMI were considered [1,3,4,6]. We separately fitted similar models with central-site PM 2.5 to compare with MISR-derived PM 2.5 models.…”

“…Numerous studies have examined the association between exposure to traffic-related air pollution and children's respiratory health [1][2][3][4]. Long-term exposure to air pollution, indicated by concentrations of nitric oxides (NO, NO 2 , NO x ), ozone (O 3 ), particulate matter with aerodynamic diameter less than 2.5 µm (PM 2.5 ), and particulate matter with aerodynamic diameter less than 10 µm (PM 10 ), has been shown to lead to reduced lung development in children [5].…”

Studies of the association between air pollution and children’s health typically rely on fixed-site monitors to determine exposures, which have spatial and temporal limitations. Satellite observations of aerosols provide the coverage that fixed-site monitors lack, enabling more refined exposure assessments. Using aerosol optical depth (AOD) data from the Multiangle Imaging SpectroRadiometer (MISR) instrument, we predicted fine particulate matter, PM 2.5 , and PM 2.5 speciation concentrations and linked them to the residential locations of 1206 children enrolled in the Southern California Children’s Health Study. We fitted mixed-effects models to examine the relationship between the MISR-derived exposure estimates and lung function, measured as forced expiratory volume in 1 second (FEV 1 ) and forced vital capacity (FVC), adjusting for study community and biological factors. Gradient Boosting and Support Vector Machines showed excellent predictive performance for PM 2.5 (test R 2 = 0.68 ) and its chemical components (test R 2 = –0.71). In single-pollutant models, FEV 1 decreased by 131 mL (95% CI: − 232 , − 35 ) per 10.7-µg/m 3 increase in PM 2.5 , by 158 mL (95% CI: − 273 , − 43 ) per 1.2-µg/m 3 in sulfates (SO 4 2 − ), and by 177 mL (95% CI: − 306 , − 56 ) per 1.6-µg/m 3 increase in dust; FVC decreased by 175 mL (95% CI: − 310 , − 29 ) per 1.2-µg/m 3 increase in SO 4 2 − and by 212 mL (95% CI: − 391 , − 28 ) per 2.5-µg/m 3 increase in nitrates (NO 3 − ). These results demonstrate that satellite observations can strengthen epidemiological studies investigating air pollution health effects by providing spatially and temporally resolved exposure estimates.

“…The built environment in urban areas (i.e. ‘grey’ surfaces, which comprise industrial, transport and urban features) appears to have side effects on children’s health, mainly due to increasing exposure to air pollution, noise and high temperatures, lower access to natural environments, and accentuated sedentary life [ 13 – 16 ]. Apart from air pollution, there have been few investigations on the association between “urbanicity” and respiratory and allergic symptoms in childhood [ 2 , 17 ].…”

Associations of greenness, greyness and air pollution exposure with children’s health: a cross-sectional study in Southern Italy

BackgroundDue to the complex interplay among different urban-related exposures, a comprehensive approach is advisable to estimate the health effects. We simultaneously assessed the effect of “green”, “grey” and air pollution exposure on respiratory/allergic conditions and general symptoms in schoolchildren.MethodsThis study involved 219 schoolchildren (8–10 years) of the Municipality of Palermo, Italy. Data were collected through questionnaires self-administered by parents and children. Exposures to greenness and greyness at the home addresses were measured using the normalized difference vegetation index (NDVI), residential surrounding greyness (RSG) and the CORINE land-cover classes (CLC). RSG was defined as the percentage of buffer covered by either industrial, commercial and transport units, or dump and construction sites, or urban fabric related features. Two specific categories of CLC, namely “discontinuous urban fabric - DUF” - and “continuous urban fabric - CUF” - areas were found. Exposure to traffic-related nitrogen dioxide (NO2) was assessed using a Land-Use Regression model. A symptom score ranging from 0 to 22 was built by summing affirmative answers to twenty-two questions on symptoms. To avoid multicollinearity, multiple Logistic and Poisson ridge regression models were applied to assess the relationships between environmental factors and self-reported symptoms.ResultsA very low exposure to NDVI ≤0.15 (1st quartile) had a higher odds of nasal symptoms (OR = 1.47, 95% CI [1.07–2.03]). Children living in CUF areas had higher odds of ocular symptoms (OR = 1.49, 95% CI [1.10–2.03]) and general symptoms (OR = 1.18, 95% CI [1.00–1.48]) than children living in DUF areas. Children living in proximity (≤200 m) to High Traffic Roads (HTRs) had increased odds of ocular (OR = 1.68, 95% CI [1.31–2.17]) and nasal symptoms (OR = 1.49, 95% CI [1.12–1.98]). A very high exposure to NO2 ≥ 60 μg/m3 (4th quartile) was associated with a higher odds of general symptoms (OR = 1.28, 95% CI [1.10–1.48]). No associations were found with RGS. A Poisson ridge regression model on the symptom score showed that children living in proximity to HTRs (≤200 m) had a higher symptoms score (RR = 1.09, 95% CI [1.02–1.17]) than children living > 200 m from HTRs. Children living in CUF areas had a higher symptoms score (RR = 1.11, 95% CI [1.03–1.19]) than children living in DUF areas.ConclusionsMultiple exposures related to greenness, greyness (measured by CORINE) and air pollution within the urban environment are associated with respiratory/allergic and general symptoms in schoolchildren. No associations were found when considering the individual exposure to greyness measured using the RSG indicator.Electronic supplementary materialThe online version of this article (10.1186/s12940-018-0430-x) contains supplementary material, which is available to authorized users.

Changes in the modern way of life happened due to the industrial revolution, along with the evolution and increase in the use of technology. Despite the existing benefits, these changes caused the accumulation of pollutants and the proliferation of environmental pollution. From this perspective, the problem of exposure of humans to pollutants and contaminants in everyday life and working environments has been emerged. Air pollutants are a special category of which an interesting subcategory is the pollutants of nitrous oxides, rising sharply in the years of industrialization and automation of human life. In the present study, we will examine the properties of air pollutants, and in particular those of nitric oxides, referring to their environmental impacts and hence to the working environment, since the effects are similar along with some public health issues emerging from human exposure to the oxides of nitrogen.
