Potentially Harmful Elements and Human Health

摘要: Potentially harmful elements, or more generally trace are now considered to be among the most effective environmental contaminants, and their release into environment is increasing since last decades. Metals released by different sources, both natural anthropic, can dispersed in accumulated plants and, ultimately, human body, causing serious health problems as intoxication, neurological disturbances also cancer.
