“…Third, this study used only measures of NO x and PM 2.5 and cannot inform about risks related to other criteria pollutants, notably carbon monoxide. Relatedly, our measure of NO x could be a marker of other, unmeasured traffic-related air pollutants, 45 such as elemental carbon and lead. Because lead was not banned from gasoline in the UK until 2000 (at approximately 6 years of age for E-Risk study children), participants with higher NO x exposure also likely had higher early life lead exposure.…”

Association of Air Pollution Exposure in Childhood and Adolescence With Psychopathology at the Transition to Adulthood

Key Points Question Is exposure to outdoor air pollution in childhood and adolescence associated with the development of psychopathology at the transition to adulthood? Findings In this cohort study of 2039 UK-born children followed up for 2 decades, early-life exposure to nitrogen oxides was significantly associated with general psychopathology at 18 years of age, representing greater internalizing, externalizing, and thought disorder symptoms. The associations were not attributable to individual or family-level factors or to disadvantageous neighborhood characteristics. Meaning These findings suggest that exposure to nitrogen oxides in early life may be a nonspecific risk factor for the development of psychopathology as young people begin the transition to adulthood.

“…In some countries, like China, there is a strong tradition for outdoor exercise and few indoor facilities (10). It is recognized that increased exposure to traffic-related air pollution (TRAP), i.e., the air pollution originating from the emissions of motor vehicles and resulting from fossil fuel combustion, may exert negative effects on respiratory health (11).…”

Traffic-related air pollution (TRAP) is increasing worldwide. Habitual physical activity is known to prevent cardiorespiratory diseases and mortality, but whether exposure to TRAP during exercise affects respiratory health is still uncertain. Exercise causes inflammatory changes in the airways, and its interaction with the effects of TRAP or ozone might be detrimental, for both athletes exercising outdoor and urban active commuters. In this Mini-Review, we summarize the literature on the effects of exposure to TRAP and/or ozone during exercise on lung function, respiratory symptoms, performance, and biomarkers. Ozone negatively affected pulmonary function after exercise, especially after combined exposure to ozone and diesel exhaust (DE). Spirometric changes after exercise during exposure to particulate matter and ultrafine particles suggest a decrease in lung function, especially in patients with chronic obstructive pulmonary disease. Ozone frequently caused respiratory symptoms during exercise. Women showed decreased exercise performance and higher symptom prevalence than men during TRAP exposure. However, performance was analyzed in few studies. To date, research has not identified reliable biomarkers of TRAP-related lung damage useful for monitoring athletes' health, except in scarce studies on airway cells obtained by induced sputum or bronchoalveolar lavage. In conclusion, despite partly counteracted by the positive effects of habitual exercise, the negative effects of TRAP exposure to pollutants during exercise are hard to assess: outdoor exercise is a complex model, for multiple and variable exposures to air pollutants and pollutant concentrations. Further studies are needed to identify pollutant and/or time thresholds for performing safe outdoor exercise in cities.

“…In urban areas, TRAP, which comprise a mixture of vehicle exhausts, secondary pollutants, evaporative emissions from vehicles, and non-combustion emissions (such as road dust), is a main source of outdoor air pollution. 37 Since it is impossible to measure all the components of TRAP, surrogates have been used to represent TRAP-related exposure. 38 The most commonly used surrogates include measured or modeled concentrations of pollutant surrogates, including NO 2 , CO, elemental carbon, PM, and ultrafine particles, and direct measures of traffic, including proximity/distance of the residence to the main road and traffic volume within the buffer.…”

Exposure to outdoor air pollution has been consistently associated with asthma. In this study, we reviewed the epidemiological studies published within the last 5 years on the association between outdoor air pollution and exacerbation and onset of asthma. A large number of studies have been published within the last 5 years. Short-term exposure to outdoor air pollution is associated with exacerbation of pre-existing asthma, manifested as worsening of symptoms and increasing of asthma-related emergency room visits and hospital admissions. Furthermore, increasing evidence suggests that long-term exposure to outdoor air pollution can result in onset of asthma. Children are more susceptible to outdoor air pollution. Future studies should be conducted to explore the mechanisms underlying the association between air pollutants and onset of asthma, including gene involvement. In addition, disentangling the effect of a mixture of air pollutants and identifying the key components of air pollution will complete the existing evidence. More importantly, a better understanding is required on the future impact of air pollution on asthma under a changing climate.
