According to an editorial, exposure to environmental metals remains substantial because of widespread soil contamination; persistence of past uses (house paint and plumbing for lead); continuing industrial uses (plastics and batteries); and presence in tobacco and tobacco smoke, drinking water and ambient air, and dust near industrial sources and waste sites. In addition, cadmium content in fertilizers provide an additional exposure pathway through diet and tobacco since vegetables and grains bioconcentrate cadmium. Emerging tobacco products such as electronic cigarettes also increase metal exposure; the main source being the heating coil, from where metals leach into the inhaled aerosol. It note that despite widespread distribution of toxic metal contaminants, technical reports from environmental and public health agencies often disregard the mounting evidence of associated cardiovascular risk. Similarly, metal exposures are neglected by the organizations that produce cardiovascular prevention guidelines. It concludes that the current evidence suggests a clear need to minimise unnecessary metal exposures.
