Zinc protoporphyrin reflects the toxic effects of lead on an erythrocyte enzyme system. Levels usually begin to rise when the blood lead level exceeds 40 μ g/100 mL. Once elevated, zinc protoporphyrin tends to remain above background levels for several months (the 120-day life span of RBCs).
The lead, manganese, zinc, and copper mixture was chosen for an interaction profile because these metals frequently occur together in completed exposure pathways at hazardous waste sites. Because these metals are commonly found in soil, the exposure scenario of greatest concern for this mixture is long-term, low-level oral exposure ( ATSDR ...
Zinc (Zn) is an abundant metal, found in the Earth's crust, with a myriad of industrial and biological uses. At room temperature, zinc is brittle and blue-white in color, but it can be polished to a bright finish. A base metal, zinc is primarily used to galvanize steel, a process that protects the metal against unwanted corrosion.
