What were the results of arsenic testing in urine in Churchill County?
Thirty-four percent of the Churchill County population tested for arsenic in their urine had a level above our reference value of 50 μg/L. Normal urine levels of arsenic are less than 50 μg/L. A level between 50 and 200 μg/L should be monitored by your physician but does not necessarily represent a health risk. A level over 200 μg/L is considered abnormal and may require treatment if symptoms of arsenic poisoning are present. The best test to confirm too much arsenic exposure is a 24-hour urine collection and analysis after 3 days of a seafood-free diet.
