In that year, Wanklyn and Chapman speculated on the adverse effects of the heavy metals "arsenic, lead, copper, zinc, iron and manganese" in drinking water. They noted an ...
Trivalent chromium, or chromium(III), is an essential trace mineral in the human diet. [3] In some nutritional supplements, chromium(III) occurs as chromium(III) picolinate (in which chromium is bound to picolinic acid) or chromium(III) nicotinate (in which chromium is bound to nicotinic acid). Nicotinic acid is also known as the B vitamin niacin.
Although the safety of daily chromium doses of up to 1,000 μg has been shown, there are some reports of serious adverse effects by using chromium picolinate, including kidney failure from a six-week course of 600 μg per day and liver disease after using 1,200 to 2,400 μg per day over four to five months.

[41] [42] Average hexavalent chromium levels in Hinkley were recorded at 1.19 ppb, with an estimated peak of 20 ppb.
