Arsenic
Most concerning exposure is from water

Content: Very high exposure to arsenic can cause noticeable changes to skin and nails, such as yellowing of the fingernails or certain pattern of skin changes that resemble warts, called "hyperkeratosis." Arsenic is harmful to the nervous system. Symptoms of arsenic exposure include tremors, headaches, and numbness. Other effects may include blood vessel damage, high blood pressure, anemia, stomach upsets, and diabetes. Children could be impacted
Prenatal and early childhood exposures to arsenic can increase the risk of lung cancer and respiratory disease in later life. Arsenic exposure has also been associated with lower IQ scores in school-aged children and can affect learning. The current standard is intended to protect the developing fetus and young children from these effects. Medical Tests
Urine can be tested for arsenic up to a week after the exposure. Arsenic can also be measured in hair and fingernails within a few months of exposure. The results of arsenic urine tests may be misleading if you have eaten seafood, marine fish or ocean-derived vitamin supplements in the past five days.
