According to a new study by the Lancet Commission, pollution was responsible for approximately 9 million premature deaths in 2019.
The study, published Tuesday in the Lancet Planetary Health journal, found that one in six premature deaths globally were caused by pollution in 2019, a figure unchanged since 2015.
Air pollution accounted for the majority of premature deaths at 6.7 million, and water pollution accounted for 1.4 million deaths.
Experts expressed alarm over the rising number of deaths from chemical pollution as lead poisoning took almost one million lives.
The study also reported that 90 percent of these deaths occured in low- and middle-income countries, while cause shifted from indoor air pollution or contaminated water to industrial and chemical pollution.
