What health risks are associated with arsenic consumption in drinking water?
Long-term exposure to arsenic from drinking-water and food can cause cancer and skin lesions. It has also been associated with cardiovascular disease and diabetes. In utero and early childhood exposure has been linked to negative impacts on cognitive development and increased deaths in young adults.
Where does arsenic in well water come from?
How does arsenic get into well water? Your private well water comes from underground water supplies. Arsenic can get into groundwater through the erosion of natural mineral deposits or from industrial activities.
Can arsenic be found in drinking water?
For most people, food and water are the biggest sources of arsenic exposure. There are two forms of arsenic: Inorganic arsenic is the type found in drinking water and is the more harmful type of arsenic. It is also found in rice, cereal grains, and other foods.
What causes arsenic contamination in groundwater?
The main anthropogenic sources for contamination of groundwater with As are mining, burning of fossil fuels, use of arsenical fungicides, herbicides and insecticides in agriculture, and wood preservatives .
How long does arsenic stay in your system?
Both inorganic and organic forms leave your body in your urine. Most of the inorganic arsenic will be gone within several days, although some will remain in your body for several months or even longer. If you are exposed to organic arsenic, most of it will leave your body within several days.
How does arsenic interfere with the body?
Soluble inorganic arsenic can have immediate toxic effects. Ingestion of large amounts can lead to gastrointestinal symptoms such as severe vomiting, disturbances of the blood and circulation, damage to the nervous system, and eventually death.
Does a Brita filter remove arsenic?
We confirm the ability of the ZeroWater® filter to reduce the arsenic concentration by 99%, and observed that the Brita filter reduced the arsenic concentration by 22.6% and 28.6% when the influent arsenic concentration is 10 μg/L and 100 μg/L, respectively.
Can you remove arsenic from well water?
The most cost-effective method for removing arsenic from a private water supply appears to be reverse osmosis, commonly called RO. RO can be thought of as filtration at a molecular level. It works by forcing water through a special, selective membrane.
How do you test for arsenic in water at home?
The total concentration of arsenic in drinking water can be detected by simple Gutzeit method, and some similar colorimetric methods of comparing stains produced on treated paper strips.
How much is too much arsenic in well water?
If arsenic in your water is above 100 ppb (0.100 ppm), you should not use it for long-term irrigation. The amount of arsenic in soil may build up over a period of years and pose a direct hazard to humans by accumulating in food crops.
Does arsenic have any health benefits?
Arsenic is also contained in traditional Chinese medicine formulas and used for psoriasis; syphilis; asthma; joint pain (rheumatism); hemorrhoids; cough; itchiness; cancer; to reduce swelling (as an anti-inflammatory agent); and as a general tonic and pain-killer.
How do you test for arsenic?
The most reliable way to test for recent arsenic exposure is through a urine test. If you had a fish meal or ate fish supplements within a few days of having a urine test, the test may show a high level of arsenic.
How do you tell if you have been poisoned by arsenic?
Symptoms of arsenic poisoning
- red or swollen skin.
- skin changes, such as new warts or lesions.
- abdominal pain.
- nausea and vomiting.
- abnormal heart rhythm.
- muscle cramps.
- tingling of fingers and toes.
What foods are high in arsenic?
The highest levels of arsenic (in all forms) in foods can be found in seafood, rice, rice cereal (and other rice products), mushrooms, and poultry, although many other foods, including some fruit juices, can also contain arsenic.
How is arsenic treated in groundwater?
Both species of arsenic can be removed from drinking water through adsorption using a granular ferric oxy-hydroxide media. In this process, the media is typically utilized on a single-use basis to treat pre-chlorinated groundwater containing arsenate in the range of 11 to 40 ppb with neutral pH conditions.
