Heavy metal intoxication

Abstract

Although some debate exists with regards to the subject, elements which are classified under ‘heavy metals’ have come to be those which pose a threat to humans in terms of toxicity. Intoxication with heavy metals is not a typical diagnosis as it is fairly uncommon. This can impose a risk on people who fail to be diagnosed and removed from the source of exposure, increasing morbidity and mortality. For the purposes of this review, Cadmium and Mercury will be discussed. A brief introduction of each element’s chemical and physical properties will be given, as well as its sources in the environment and any uses. Each metal’s toxicity will be illustrated using actual cases of poisoning. Any treatments for intoxication will be explained at the end of each section.
