Oil pollution accumulates in the air, in the soil, and in people’s bodies. When it reaches a certain level, it causes illness or death. The Kurds of northeast Syria were valiant against IS, but today they face a potentially even more deadly scourge, putting the lives of four million local residents at risk. Syria’s contested crude oil is leaking from dilapidated pipelines and contaminating rivers and streams. When the rivers flood, as they did in April, they spread their poison over agricultural crops, just as thousands of rudimentary refineries belch their own toxic fumes into the air. Sporadic protests have resulted in makeshift refineries being shut down, only for them to pop up elsewhere. Locals in affected areas say that many dangerous illnesses caused by the pollution are multiplying. Residents requested anonymity, fearing retribution from authorities - a telling sign of how caustic the danger is.

It is called the largest mass poisoning in history. Wells drilled in the Indian subcontinent in the 1970s exposed millions to arsenic leaching into their drinking water from surrounding rocks and soil; this has caused skin lesions, cancer, cardiovascular diseases, and neurodevelopmental delays. A new study now suggests that up to sixty million Pakistanis might also be exposed to contaminated water. The World Health Organisation warned in the 1990s that up to 77 million people in Bangladesh were in danger of drinking water with unsafe levels of arsenic, and 200 million people in Nepal, Bangladesh, India and Vietnam were exposed to concentrations exceeding the recommended limit. Experts hope this new study will motivate Pakistan’s authorities to test wells in high-risk areas and to warn communities. If people are aware of the risks they could use water from deeper aquifers that are in contact with older sediments, or invest in treating groundwater to remove arsenic.
