The chemical spill following a train derailment in East Palestine, Ohio, has led to concerns about water, air and soil. The spill has drawn comparisons to other environmental disasters despite government officials saying testing has shown that municipal water is safe to drink and the air is clean.
Here's a look at other environmental disasters from the past 50 years:
Chernobyl Nuclear Disaster, 1985
The Chornobyl nuclear incident in Ukraine is likely the most well-known environmental disaster. In 1986, an explosion at the Chornobyl Nuclear Power Plant released a large amount of radioactive material into the atmosphere. More than 30 people died immediately following the explosion and tens of thousands of people in the region were exposed to dangerous levels of radiation. While the long-term health issues are still being studied, it's believed that the disaster led to an increase in cancer and other ailments. The surrounding area of the Chornobyl Nuclear Power Plant is still considered uninhabitable.
Exxon Valdez Oil Spill, 1989
The Exxon Valdez oil spill occurred in March 1989 when an oil tanker ran around in Alaska. It's estimated that the tanker spilled 11 million gallons of crude oil into the ocean. Thousands of birds and marine animals died because of the spill. Exxon reportedly paid about $4 billion for the cleanup and habitat restoration efforts. However, many environmentalists claim the effects of the spill are still being felt today.
Baia Mare Cyanide Spill, 2010
The Baia Mare, Romania, cyanide spill is considered one of the worst environmental disasters Europe has ever experienced. In January 2000, the failure of a dam at a gold mine caused the release of water containing high levels of cyanide into the nearby Somes River. It quickly spread downstream, killing a large number of aquatic life. Dozens of people were reportedly hospitalized after eating contaminated fish from the river.
Deepwater Oil Spill, 2010
The Deepwater Horizon oil spill was an environmental disaster that began with an explosion on a BP oil rig in the Gulf of Mexico in 2010. Eleven workers were killed in the explosion that sent about 5 million barrels of oil into the ocean for 87 days. The spill devastated marine and wildlife habitats in the Gulf. BP and its partners reportedly spent about $70 billion on cleanup costs over 10 years.
