Shrek drinks a tube well water that contains 50 µg/L of arsenic. Assume that he is exposed to arsenic for 35 years, drinks 2 L/day of water, 7 days/wk, 50 weeks per year (every year he visits his in-laws for a few weeks), and weighs 70 kg. Also assume 80% of the arsenic is absorbed. What is the LADD (in mg/kg-d) over 70 years? 0.000712 0.00057 0.000685 0.000548
