Researchers at the University of Washington and UW Tacoma are studying arsenic levels in mud, water, and lake creatures in southern Puget Sound. Eating contaminated fish and snails from these lakes can pose a health risk.
Contamination of local smelter emissions can be the cause of high concentrations of arsenic found at the bottom of lakes in King and Pierce counties. Arsenic is a chemical that is associated with an increased risk of cancer.
Researchers have found that despite the similarities between Angle Lake and Lake Killarney, creatures living in shallow lakes (Bonney, Steel, Killarney, etc.) are at a higher level than creatures living in deep lakes (Angle Lake, etc.). I found that I was more likely to have arsenic at the bottom arsenic level. The team detected levels associated with an increased cancer risk for the following activities:
- Eat the snails of the surveyed lake once a month
- Eat crayfish from Lake Steel and Lake Killarney once a month
- Eat sunfish from Lake Killarney twice a month
The team is currently working with the Ministry of Health and the Ministry of Ecology on actions to protect human health. Researchers are also beginning to work on affordable and effective ways to clean the lake.
