The Short- and Long-Run Impacts of Air Pollution on Human Health: New Evidence from China.

Under the background of the far-reaching impact of the COVID-19 epidemic on global economic development, the interactive effect of economic recovery and pollution rebound makes the research topic of air pollution and human health receive attention again. Matching a series of new datasets and employing thermal inversion as an instrumental variable, this study investigates the physical and mental health effect of air pollution jointly in China. We find that in the short run, the above inference holds for both physical and mental health. These short-run influences are credible after a series of robustness checks and vary with different individual characteristics and geographical locations. We also find that in the long run, air pollution only damages mental health. Finally, this study calculates the health cost of air pollution. The above findings indicate that in China, the effect of air pollution on physical and mental health cannot be ignored. The government needs to consider the heterogeneity and long-run and short-run differences in the health effects of air pollution when formulating corresponding environmental and medical policies.

Impact of Air Pollution on Mental Health in India

There is extensive evidence linking air pollution exposure to physical health. Less is known about the mental health impacts of poor air quality, especially in developing countries. We use data from India and estimate the causal impact of air pollution exposure on feeling sad, experiencing cognitive difficulties, and feeling unable to control and cope with important things in life. We instrument for air pollution exposure using the annual number of nighttime thermal inversions and show that air pollution exposure in the previous calendar year significantly worsens mental health in the current year. We examine potential mechanisms and find that air pollution exposure negatively impacts self-reported physical health, worsens respiratory conditions, and increases the likelihood of experiencing sleeping difficulties. Accounting for mental health impacts of pollution exposure is critical to accurately estimating the true health costs of air pollution and designing optimal environmental policy.

The short-term impact of air pollution on medical expenditures: Evidence from Beijing

We identify the short-term effects of PM2.5 concentrations on medical costs in Beijing by analyzing two datasets: one detailing daily air quality indexes over a four-year period and the other containing individual-level records of all health care visits and medical transactions that occurred under a government insurance program that covers most city residents. We find that both higher levels of air pollution and longer-lasting pollution episodes significantly increase health care visits and medical expenditures. An analysis of multiple-day pollution episodes shows that marginal health care visits and marginal health costs start to increase as the pollution event lasts for consecutive days. Omitting the variation in the magnitude of the marginal effects of pollution exposure over the course of a pollution episode would lead to the underestimation of the total health costs of air pollution. Our findings provide empirical evidence that both the intensity and the duration of pollution episodes are critical considerations when designing policies to reduce the health costs of air pollution.

The impact of air pollution on individual subjective well-being: Evidence from China

Linkages between air pollution and individual subjective well-being (SWB) are theorized as a key component of the United Nations Sustainable Development Goals. Using the China Family Panel Studies (CFPS) covering 12,668 residents who were interviewed for five consecutive times during 2010–2018, we find significant negative effects of air pollution on individual SWB via the change of the respondent's physical health level, physical exercise behavior and obesity risk. Specifically, a one standard deviation increase in county's annual average PM2.5 concentrations, instrumented by thermal inversion, is associated with a 2.45 standard deviations decrease in individual SWB level. In particular, people who are male, young people, less educated group, urban resident and live in eastern or western China are more sensitive to air pollution. This paper provides new insights into the health costs of air pollution.

Health Cost Estimation of Traffic-Related Air Pollution and Assessing the Pollution Reduction Potential of Zero-Emission Vehicles in Toronto, Canada

Fossil fuel vehicles, emitting air toxics into the atmosphere, impose a heavy burden on the economy through additional health care expenses and ecological degradation. Air pollution is responsible for millions of deaths and chronic and acute health problems every year, such as asthma and chronic obstructive pulmonary disease. The fossil-fuel-based transportation system releases tons of toxic gases into the atmosphere putting human health at risk, especially in urban areas. This analysis aims to determine the economic burden of environmental and health impacts caused by Highway 401 traffic. Due to the high volume of vehicles driving on the Toronto Highway 401 corridor, there is an annual release of 3771 tonnes of carbon dioxide equivalent (CO2e). These emissions are mainly emitted onsite through the combustion of gasoline and diesel fuel. The integration of electric and hydrogen vehicles shows maximum reductions of 405–476 g CO2e per vehicle-kilometer. Besides these carbon dioxide emissions, there is also a large amount of hazardous air pollutants. To examine the impact of air pollution on human health, the mass and concentrations of criteria pollutants of PM2.5 and NOx emitted by passenger vehicles and commercial trucks on Highway 401 were determined using the MOVES2014b software. Then, an air dispersion model (AERMOD) was used to find the concentration of different pollutants at the receptor’s location. The increased risk of health issues was calculated using hazard ratios from literature. Finally, the health cost of air pollution from Highway 401 traffic was estimated to be CAD 416 million per year using the value of statistical life, which is significantly higher than the climate change costs of CAD 55 million per year due to air pollution.

When particulate matter strikes cities: Social disparities and health costs of air pollution

We investigate the heterogeneous effects of particle pollution on Italian daily hospitalizations and their costs by exploiting public transportation strikes as plausibly-exogenous shocks in pollution exposure. We find that a one standard deviation increase in PM10 causes additional 0.79 hospitalizations per 100,000 residents, and the effect is stronger for the elderly, low educated individuals and migrants. Furthermore, we find that young individuals, an arguably healthy age group, exhibit economically meaningful responses to air pollution with an effect ranging between 0.45 and 1.04. Our results imply a large role of avoidance behavior driving heterogeneous marginal health effects. Total daily costs of a one standard deviation increase in PM10 represent 0.5% of the total daily health expenditure, and 85% of this additional spending comes from more patients hospitalized, while the remaining 15% can be attributable to more costly, and likely more complex, hospitalizations.

Transition in air pollution, disease burden and health cost in China: A comparative study of long-term and short-term exposure.

Ambient air pollution is one of the leading environmental risk factors to human health, largely offsetting economic growth. This study evaluated health burden and cost associated with the short-term and long-term exposure of major air pollutants (fine particulate matter [PM2.5] and ozone [O3]) during 2013-2018. We developed a database of gridded daily and annual PM2.5 and O3 exposure in China at 15km×15km resolution. Then, we estimated the age- and cause-specific premature deaths and quantified related health damage with an age-adjusted value of statistical life (VSL) measure. The health cost estimated in this study captured direct cost, indirect cost and intangible cost of the premature death attributable to ambient PM2.5 and O3. We found that the national premature deaths attributable to long-term and short-term exposure to PM2.5 decreased by 15% and 59%, whereas the national premature deaths attributable to long-term and short-term exposure to O3 increased by 36% and 94%. Despite a 15% reduction of attributable deaths, the health cost attributable to long-term exposure to PM2.5 did not change significantly as a result of GDP growth and population aging. On the other hand, the long-term O3 related health cost in 2018 doubled that in 2013. Our study suggests that while premature deaths fell as a result of China's clean air actions, the health costs of air pollution remained high. The growing trends of O3 highlighted the needs for strategies to reduce both PM2.5 and O3 emissions, for the sake of public health and social well-being in China.

Consensus and entrepreneurship: The contrasting local and national politics of UK air pollution

Air pollution in the UK has recently re-emerged as a major policy problem. Insights from the agenda-setting literature are used here to explain the extent to which air quality has become a national political issue, and a local issue in London. The article explores the development of a problem stream in which scientific experts and non-governmental actors have since the late 2000s, provided evidence related to the economic and particularly health costs of air pollution, and increasingly framed the problem as urgent. Key focusing events have also contributed to increasing media coverage and public concern. Explanations are offered for the limited policy response at the national level compared to London. The research is based on primary data which includes 16 elite interviews with key actors, manifestos from London Mayoral and UK general elections, and local and national government policy documents. In London there is broad cross-party consensus and relatively high public concern, and a mayor acting as a policy entrepreneur, able to build upon pre-existing congestion charging policy. In contrast, at the national level there is a shared understanding that air pollution constitutes a problem, but less consensus on its scale amongst the public and across political parties, fragmented policy making and responsibility for the issue and little agreement on the appropriate policy response.

When Particulate Matter Strikes Cities. Social Disparities and Health Costs of Air Pollution

We investigate the heterogeneous effects of daily particular matter (PM) pollution on Italian hospitalizations and their costs. We exploit public transportation strikes as plausibly-exogenous shocks in PM. We find that young individuals, an arguably healthy age group, exhibit economically meaningful responses to changes in air pollution. A higher prevalence of pollution-induced hospitalizations also exists among the elderly, low educated individuals and migrants coming from low income countries. Our results imply a large role for differential avoidance behavior driving heterogeneous marginal effects. PM exposure also affects the intensive margin since pollution-induced hospitalizations are not only more frequent but they are characterized by a higher complexity, generating additional costs.

Polluted Morality: Air Pollution Predicts Criminal Activity and Unethical Behavior

Air pollution is a serious problem that affects billions of people globally. Although the environmental and health costs of air pollution are well known, the present research investigates its ethical costs. We propose that air pollution can increase criminal and unethical behavior by increasing anxiety. Analyses of a 9-year panel of 9,360 U.S. cities found that air pollution predicted six major categories of crime; these analyses accounted for a comprehensive set of control variables (e.g., city and year fixed effects, population, law enforcement) and survived various robustness checks (e.g., balanced panel, nonparametric bootstrapped standard errors). Three subsequent experiments involving American and Indian participants established the causal effect of psychologically experiencing a polluted (vs. clean) environment on unethical behavior. Consistent with our theoretical perspective, results revealed that anxiety mediated this effect. Air pollution not only corrupts people’s health, but also can contaminate their morality.

Estimating the Health Cost of Air Pollution: The Case of Morocco

Globally, ambient fine particulate matter (PM2.5) is the fifth leading cause of death. Household air pollution from use of solid fuels is the tenth ranked cause of death. Together, ambient and household air pollution caused 6.4 million deaths worldwide. In the Middle East and North Africa region, an estimated 125,000 lives are lost annually to diseases associated with ambient and household air pollution. This paper estimates the economic cost of air pollution in Morocco, a country marked by rapid economic development and urbanization. Using the most updated causal relationships between long-term exposure to PM2.5 and premature mortality, the paper estimates that air pollution costs society about US$1.14 billion annually, or 1.05 percent of the country’s GDP in 2014. Ambient air pollution is responsible for nearly three quarters of this cost, as a result of large exposure to high PM2.5 levels in cities like Casablanca, Tangier, and Marrakesh. Household air pollution is a problem particularly for rural households using solid fuels for cooking and heating. Based on these results, the paper identifies the most affected areas and the most vulnerable groups in the country.

Human Health Cost of Air Pollution in Kazakhstan

Kazakhstan, like other former Soviet Republics, inherited a number of serious environmental problems. Air pollution is one of these serious problems, leading to significant environmental health effects on the population of Kazakhstan. This study provides a baseline analysis of health damages from air pollution, based on readily available information. Mean estimates of mortality risk attributable to air pollution are about 16,000 cases per year with a 95% confidence level of the risk not exceeding 25,500. Even taking into account all the uncertainties related to the collection and processing of primary data, as well as the application of risk analysis methodology, we conclude that air pollution in Kazakhstan constitutes a significant contribution to the environmental burden of diseases. In relative terms, the impact of air pollution on premature mortality in Kazakhstan is notably higher than in Russia and the Ukraine.

The health and visibility cost of air pollution: a comparison of estimation methods

Air pollution from motor vehicles, electricity-generating plants, industry, and other sources can harm human health, injure crops and forests, damage building materials, and impair visibility. Economists sometimes analyze the social cost of these impacts, in order to illuminate tradeoffs, compare alternatives, and promote efficient use of scarce resource. In this paper, we compare estimates of the health and visibility costs of air pollution derived from a meta-hedonic price analysis, with an estimate of health costs derived from a damage-function analysis and an estimate of the visibility cost derived from contingent valuation. We find that the meta-hedonic price analysis produces an estimate of the health cost that lies at the low end of the range of damage-function estimates. This is consistent with hypotheses that on the one hand, hedonic price analysis does not capture all of the health costs of air pollution (because individuals may not be fully informed about all of the health effects), and that on the other hand, the value of mortality used in the high-end damage function estimates is too high. The analysis of the visibility cost of air pollution derived from a meta-hedonic price analysis produces an estimate that is essentially identical to an independent estimate based on contingent valuation. This close agreement lends some credence to the estimates. We then apply the meta hedonic-price model to estimate the visibility cost per kilogram of motor vehicle emissions.

EXTERNAL HEALTH COSTS OF A STEEL MILL

Intermittent operation of a steel mill in a mountain valley in central Utah provides a unique opportunity to measure the external health costs of air pollution. A nearby valley provides a control. This paper analyzes data on hospital admissions and daily deaths for the two valleys, using negative binomial regression models of daily hospital admissions and deaths. Hospital admissions for respiratory diseases increase significantly when the mill is in operation. Mortality also increases during mill operation. Estimated excess hospitalization costs are about 2 million dollars per year, and the increased cost of mortality exceeds 40 million dollars per year.

Health costs of air pollution: a study of hospitalization costs.

This study of the hospitalization costs of exposure to air pollution in Allegheny County, Pennsylvania was conducted to determine whether persons exposed to air pollution incurred higher hospital utilization rates and additional costs for treatment. A hospitalization data-base comprising 37,818 total admissions for respiratory, suspect circulatory diseases, and comparison circulatory diseases was tested in a cross-section type analysis for relationships between rates of hospitalization, length of stay, and levels of air quality in the neighborhoods of patients' residence. Air quality was identified using data from 49 monitoring stations. Corrections were made for race, age, sex, smoking habits, median income, and occupation. The results show that hospitalization rates, length of stay, and costs of respiratory and suspect circulatory system diseases were significantly greater among populations residing in the more polluted zones of the County. At average costs for hospitalization in this area in 1972, the total increased cost for the 1.6 million persons in the County was estimated at $9.8 million ($9.1 million for increased hospitalization rates and $0.7 million for increased length of stay). The total health costs resulting from air pollution exposure in this area would be much greater when non-hospitalization costs are also included.

Evaluation of nationwide health costs of air pollution and cigarette smoking.

Total nationwide health costs due to air pollution and cigarette smoking were evaluated by determining the percentages of the total respiratory disease cost for 1970 due to the separate and the synergistic effects of smoking and air pollution. Previous studies known to the authors did not properly account for the well established synergistic effect of smoking and air pollution, and also assumed that the urban factor (ratio of urban incidence to rural incidence) was due primarily or exclusively to air pollution. Recent evidence strongly indicates that air pollution is not the primary cause of the urban factor, although it does make a contribution. Taking a minimum of 10% and a maximum of 50% of the urban factor to be due to air pollution, the total 1970 nationwide health cost due to air pollution was found to be between $62 million and $311 million, and the nationwide health cost due to cigarette smoking was found to be $4.23 billion.
