Arsenic contaminated drinking water is a major public health concern in 70 countries, including the US. 100 million people world wide are thought to be affected. Chronic
arsenic poisoning due to long-term exposure in drinking water causes
cancer of the skin,
lungs,
bladder and
kidney as well as other skin changes like
hyperkeratosis according to the
World Health Organization (WHO).
A new study conducted in Bangladesh has found that
folic acid supplements dramatically reduces the blood arsenic levels in exposed individuals. The study was funded by the National Institute of Environmental Health Sciences (NIEHS) at the
National Institutes of Health (NIH). Researchers found that treatment with
400 mcg. of folic acid reduced blood arsenic levels by 14%. Folate is a
B vitamin found in leafy vegetables, citrus fruits, beans and whole grains. Researchers found that
folic acid supplementation decreased the detoxification of arsenic to a form that could be more readily excreted in urine.
Effected countries include Argentina, Australia, Bangladesh, Chile, China, Hungary, India, Mexico, Peru, Thailand and
the USA (mostly western states). On a related note, a different group of researchers has discovered that ferns,
specifically the fronds Pteris vittataremove arsenic from soil and water, soaking it up through their roots and absorbing it through their fronds. These pretty ferns are available through
Edenspace at $4.95 a piece, are easy to grow and tolerate sunlight.
