Bangladesh has ranked the sixth deadliest country for pollution-related fatalities in the world and third in Southeast Asia with 207,922 deaths in 2017, according to a new study, which warns that pollution remains the world’s largest environmental threat to health.
As many as 126 people died per 100,000 population in Bangladesh in 2017 -- fourth in the Southeast Asia, said the Global Alliance on Health and Pollution (GAHP) in a report released on Wednesday (Dec 18.)
Of the fatalities, air pollution accounted for 122,734 deaths, followed by another 38,048 caused by lead pollution. As many 33,583 people died of water pollution while occupational pollution claimed 13,558 lives in 2017, according to the report.
Pollution is responsible in 2017 for 15 percent of all deaths globally, and 275 million disability-adjusted life years, says the study styled '2019 Pollution and Health Metrics: Global, Regional and Country Analysis'.
The 2019 report, which uses the most recent Global Burden of Disease data from the Institute of Health Metrics Evaluation, underscores the extent and severity of harm caused by air, water, and occupational pollution.
“We’re facing serious risks from pollution and those risks are exacerbated by climate change. The US has historically been the gold standard in tackling pollution, and today we are sadly not doing enough and the fact that we’re going backward is unconscionable,” says Gina McCarthy, former US Environmental Protection Agency Administrator.
"This report reminds us that climate change isn’t just about faraway countries or forest fires and floods – it’s about our health and the health of our kids – here and now," McCarthy added.
According to the report, the top ten countries with the most pollution deaths include both the world’s largest and wealthiest nations, and some of its poorer ones.
India and China lead in the number of pollution deaths, with about 2.3 million and 1.8 million deaths respectively. The US, the world’s third most populous country with 325 million people, makes the top ten list with 197,000 pollution-related deaths, while ranking 132nd in the number of deaths per 100,000 people.
The GAHP report updates findings published in 2017 by The Lancet Commission on pollution and health. The Commission’s seminal report, which was based on 2015 data, deemed pollution the greatest environmental cause of death and disease in the world, responsible for 1 in 6 deaths.
“The report reminds us all that pollution is a global crisis. It does not matter where you live. Pollution will find you,” says Rachael Kupka, acting Executive Director of GAHP.
Ambient air pollution kills more people around the globe than any other form of pollution. In the United States — which has invested in air, water and soil cleanup through the EPA’s Superfund program — ambient air pollution was responsible for more than half of the pollution-related deaths in 2017.
“In order to tackle pollution, we must prioritize it as an issue that affects us all, integrating it into health planning, and increasing funding to allow more research into pollution, such as monitoring pollution and its effects, and developing ways to control pollution,” says Richard Fuller, Chair of the GAHP Board of Directors.
"Pollution prevention can be highly cost-effective – helping to improve health and reduce climate impacts, while boosting economies," Fuller added.
Chad tops this list of the most pollution-related deaths in proportion to their population with 287 deaths for every 100,000 people. India, the only country that appears on all three lists, had a toll of 174 deaths for every 100,000 people.
Air pollution–both ambient and indoor–is one of the largest and most obvious types of pollution affecting global health, the report said.
Others significant revelations of the report include; the 2017 Global Burden of Disease (GBD) estimate of 8.3 million premature deaths from pollution is likely a serious undercount.
The GBD data does not account for exposure to many forms of toxic pollution, including mercury, cadmium, chromium, radionuclides, and obsolete pesticides.
What appears to be a decline in pollution deaths from a 2015 GBD estimate of 9 million deaths (reported in the 2017 Lancet Commission report) to the 2017 GBD estimate of 8.3 million deaths is due to changes in calculation methodologies, primarily related to air pollution.
New analyses, conducted by IHME’s air pollution experts, Health Effects Institute, reviewed the overlap between indoor air and outdoor air with new data and methodologies. Changes were also made in modeling for various occupational pollutants and for lead. Each of these updated the IHME calculations.
Overall, the results show an improvement in the number of premature deaths from traditional types of pollution— sanitation and household air—from 2015 to 2017, GAHP said.
But modern pollution, which is caused by industrialization and urbanization, is on the rise. Modern pollution, now responsible for 5.3 million deaths a year, is poorly addressed in development agendas. While attention is growing, the modern pollution crisis still lacks substantive focus within international development agencies.
“Although pollution is one of the world’s leading killers, it does not get the resources commensurate with the impact,” says Dr Jack Caravanos, NYU Professor in the College of Global Public Health and GAHP Advisor.
“It is difficult to trace deaths to pollution because there are so many types of pollution and end results. A person dying from a disease, for example, may not be counted as a polluted-related death even if pollution was a major factor,” Caravanos added.
According to the report, the disability impacts from pollution also continue to be undercounted. The current figure of 275 million DALYs (Disability-Adjusted-Life-Years, the internationally recognized measure of overall disease burden) will increase as data collection becomes more sophisticated.
More than two-thirds of the adverse health impacts of pollution are experienced as non-communicable diseases (NCDs).
Pollution of all types was responsible for 21% of all deaths from cardiovascular disease, 26% of deaths due to ischemic heart disease, 23% of deaths due to stroke, 51% of deaths due to chronic obstructive pulmonary disease, and 43% of deaths due to lung cancer, the report revealed.
