I've just seen news item on research linking cadmium (in diet) to breast cancer:
Quote:
In the new study, Julin and her colleagues followed nearly 56,000 Swedish women for more than 12 years. Those who had the highest level of exposure to cadmium from their diets had a 21% increased risk of breast cancer.

Knowing cadmium is one of the toxins of concern with waste incinerators, just googled.
Found a news item from last month:
Quote:
Maryland environmental officials are investigating following the discovery of elevated levels of cadmium from a municipal waste incinerator at Fort

[so don't go thinking the incinerator planned for Hong Kong is really so much advanced over the four that were shut down in HK by early 1990s, over concerns re excessive dangerous pollutants]
Also a research report on cadmium and incinerators:
Quote:
In the process of incineration, cadmium is volatilized as cadmium chloride to a considerable extent. In a series of in situ measurements it has been demonstrated that 99% of this cadmium condenses on dust particles and can be removed together with fly ash. The cadmium concentration in clean flue gas dusts amounts to about 2000 μg g−1. Therefore dust emission values should not be higher than 20–30 mg dust Nm−3. The ultimate disposal of filter ash increasingly poses difficulties on account of the mobility of cadmium.
