  1. Adjusted models include age, BMI, second-hand smoke exposure, maternal educational status, parity, anemia status, ferritin status, type of sanitation used at home, use of herbal remedy or medication, and household income. The average arsenic concentration and range for each quartile is: Q4 = 144.7 μg/L (32 μg/L – 1,400 μg/L); Q3 = 12.0 μg/L (2.1 μg/L – 31 μg/L); Q2 = 1.5 μg/L (0.9 μg/L – 2.0 μg/L); and Q1 = 0.7 μg/L (0.5 μg/L – 0.89 μg/L).
