A sample of water is analyzed and found to contain 18.6 ppb of arsenic. If a person were to drink 2.0 L of this water per day for 1.4 years, what is the maximum amount of arsenic they could accumulate in their body?
Assume that 1 year = 365 days
anwser________ grams or arsenic
1 ppb = 1 ug/L
18.6 ppb = 18.6 ug/L x 2.0L/day x 365 days/yr x 1.4 yrs = ? ug As/yr.
