Dose response function: Inverse relationship between IQ and blood lead levels (B-Pb) for B-Pb between 20 μg/L and 300 μg/L. The red line represents the linear-log dose response relationship as estimated based on pooled international data by Lanphear et al. (2005) [7]. The blue line represents the linear-interval dose response relationship as suggested by Gould et al. (2009) [22] which assumes uniform decreases between 20 and 100 μg/L, between 100 and 200 μg/L and above 200 μg/L. The dotted lines represent the 95% confidence limits for both dose response relationships
