Arsenic in detergents: possible danger and pollution hazard
Science (New York, N.Y.)
|April 17, 1970
Summary
Arsenic contamination was found in household detergents and the Kansas River. Detected levels approach the U.S. drinking water standard, raising health concerns.
Area of Science:
- Environmental Chemistry
- Public Health
Background:
- Arsenic is a toxic metalloid with significant health implications.
- Household products and natural water sources can be pathways for arsenic exposure.
Purpose of the Study:
- To quantify arsenic levels in common household detergents and the Kansas River.
- To assess potential human exposure risks based on detected arsenic concentrations.
Main Methods:
- Analysis of presoaks and household detergents for arsenic concentration.
- Measurement of arsenic levels in Kansas River water samples.
Main Results:
- Arsenic detected in detergents at 10-70 parts per million.
- Kansas River water showed arsenic levels of 2-8 parts per billion.
- Detected concentrations approach the U.S. Public Health Service's recommended drinking water standard of 10 parts per billion.
Conclusions:
- Common household detergents may contribute to environmental arsenic.
- Kansas River water arsenic levels are nearing a critical threshold for safe drinking water.
- Further investigation into arsenic sources and mitigation strategies is warranted.
