Heavy Metals Toxicity and the Environment
Cadmium in urine (usually adjusted for dilution by calculating the cadmium/creatinine ratio) indicates accumulation, or kidney burden of cadmium [100, 101]. It is estimated that about 2.3% of the U.S. population has elevated levels of urine cadmium (>2µg/g creatinine), a marker of chronic exposure and body burden [ 102 ].

Heavy metals and coal
Lead. Electrical utilities emit lead in flue gas from the burning of fuels, such as coal, in which lead is a contaminant. For example, a boiler burning a million pounds of lignite coal will release 420 pounds of lead into the atmosphere. The American Academy of Pediatrics has stated that there is no "safe level" of lead for children.
