This effect likely reflects two factors: First, lead in the blood is more accessible for chelation than is lead in the brain, based on the indications that chelators remove lead primarily by forming a soluble lead chelate that can be more readily eliminated via urinary or fecal routes, and by creating increased concentration gradients that favor lead efflux from tissues into the circulation.
