Background: Epidemiological studies have reported the associations between nitrogen dioxide (NO2) and pediatric asthma incidence, but unable to ascertain indoor NO2 sources. We estimated the pediatric asthma incidence and corresponding economic losses attributable to NO2 from indoor and outdoor sources in urban areas in China.
Cirium develops a methodology to calculate the most accurate, historic, and predicted flight emissions data in the marketplace. This will allow airlines to track the fuel efficiency of their operations and customers to track and choose the lowest possible carbon footprint when they travel. This supports climate action and SDG 13.
This paper uses a novel approach to re-examine the relationship between income inequality and pollution and shows that protecting the environment can have an added advantage of creating a just and inclusive society. Pollution threatens health and livelihoods of vulnerable groups, in turn making them even more vulnerable, creating a vicious cycle. We investigate if sustainable environmental policies can mitigate the impact of pollution on these vulnerable groups, while addressing inclusion.
This chapter focuses on the adverse effects of air pollution on the developing brain and discusses the evidence from human and animal studies suggesting that exposure to elevated air pollution during pre- and early postnatal development is associated with a number of behavioral and biochemical adverse effects.
Background: The effect of long-term exposure to air pollution on the development of chronic obstructive pulmonary disease (COPD) is still controversial, and the role of the interactions of air pollution with genetic risk and lifestyle in COPD risk is unclear. Methods: We included 452762 participants derived from the UK Biobank. Annual concentrations of air pollutions, including particle matter (PM2.5, PM10), nitrogen oxides (NOx), and nitrogen dioxide (NO2), were assessed using land-use regression model.
Background: Individuals with COPD have increased sensitivity to traffic-related air pollution (TRAP) such as diesel exhaust (DE), but little is known about the acute effects of TRAP on exercise responses in COPD. Research Question: Does exposure before exercise to TRAP (DE titrated to 300 μg/m3 particulate matter
Background: Numerous studies have quantified the associations between ambient temperature and enteric infections, particularly all-cause enteric infections. However, the temperature sensitivity of enteric infections might be pathogen dependent. Here, we sought to identify pathogen-specific associations between ambient temperature and enteric infections.
Background: Over 3 million people die every year from diseases caused by exposure to outdoor PM2·5 air pollution, and more than a quarter of these premature deaths occur in China. In addition to clean-air policies that target pollution emissions, climate policies aimed at reducing fossil-fuel CO2 emissions (eg, to avoid 1·5°C of warming) might also greatly improve air quality and public health. However, no comprehensive accounting of public health outcomes has been done under different energy pathways and local clean-air management decisions in China.
In this paper, the authors assess the impact of degrading air quality on modal shares and equivalent CO2 emissions per capita per trip for ten global cities using a scenario-based approach.
Map of study areas with changes in annual mean of PM2·5 from 2014 to 2017
Background: Air pollution might accelerate cognitive ageing; it is unclear whether large-scale interventions, such as China's Clean Air Act (CCAA), can mitigate cognitive deterioration. We aimed to evaluate the effect of CCAA on changes in cognitive function in older adults. Methods: In this population-based, quasi-experimental study, we did a difference-in-differences analysis of the data collected during the 2014 and 2018 waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS). The study design used a counterfactual analysis feature by dividing CLHLS participants into two groups.
