Water Arsenic Linked to Higher Urinary Arsenic Totals Among the U.S. Population
Arsenic is a toxic element that can be found in water sources, particularly in areas where there are natural deposits of arsenic in the soil. Exposure to arsenic can cause a range of health problems, including cancer, skin lesions, and cardiovascular disease. In the United States, public water systems are required to meet strict standards for arsenic levels, but recent research has shown that even low levels of arsenic in drinking water can have harmful effects on human health.
What is Arsenic?
Arsenic is a naturally occurring element that is found in rocks and soil. It can also be released into the environment through human activities such as mining and smelting. Arsenic is a toxic substance that can cause serious health problems when ingested or inhaled. It is classified as a carcinogen by the International Agency for Research on Cancer (IARC).
How Does Arsenic Get into Drinking Water?
Arsenic can enter drinking water sources through natural processes such as erosion and weathering of rocks and soil. It can also be released into the environment through human activities such as mining and smelting. In some areas, arsenic-rich groundwater is used for drinking water, which can lead to high levels of exposure.
The Link Between Water Arsenic and Urinary Arsenic
A recent study published in Environmental Health Perspectives found that exposure to low levels of arsenic in public drinking water was associated with higher urinary arsenic totals among the U.S. population. The study analyzed data from over 14,000 participants in the National Health and Nutrition Examination Survey (NHANES) from 2003 to 2014.
The researchers found that even at levels below the current U.S. Environmental Protection Agency (EPA) standard of 10 micrograms per liter (µg/L), exposure to arsenic in drinking water was associated with higher urinary arsenic totals. The study also found that certain populations, such as non-Hispanic whites and those living in rural areas, were more likely to have higher urinary arsenic totals.
The Health Effects of Arsenic Exposure
Exposure to arsenic can cause a range of health problems, including cancer, skin lesions, and cardiovascular disease. Long-term exposure to high levels of arsenic has been linked to an increased risk of lung, bladder, and skin cancer. Arsenic exposure can also cause skin lesions, peripheral neuropathy, and cardiovascular disease.
Protecting Yourself from Arsenic Exposure
There are several steps you can take to protect yourself from arsenic exposure:
- Test your well water: If you have a private well, it is important to have your water tested for arsenic. The EPA recommends testing every three years.
- Use a water filter: If your well water contains high levels of arsenic, you can use a water filter to remove it. Look for a filter that is certified by NSF International for arsenic removal.
- Choose bottled water: If you are concerned about the quality of your tap water, you can choose to drink bottled water instead.
- Practice good hygiene: Arsenic can be absorbed through the skin, so it is important to practice good hygiene by washing your hands frequently and taking showers instead of baths.
Conclusion
Exposure to low levels of arsenic in public drinking water is associated with higher urinary arsenic totals among the U.S. population. Arsenic is a toxic element that can cause serious health problems when ingested or inhaled. It is important to take steps to protect yourself from arsenic exposure by testing your well water, using a water filter, choosing bottled water, and practicing good hygiene.
