Trace Metals Hypertension
It has been claim that both cadmium and lead, which are environmental, pollutants, may cause high blood pressure.
Many of these associations have not been confirmed by detailed studies that have taken concurrent alcohol intake into account.
The main source of cadmium to the human body is cigarette smoke.
The evidence for the trace metal hypertension hypothesis must now be regarded as very fragile although a positive correlation between blood lead and blood pressure does appear to be genuine even after correction for possible confounding variables.
Conversely however, there is fairly good evidence that blood pressures are lower in areas where the drinking water is hard (i.e., has a higher calcium content), although the mechanisms for this association unknown.
