This story Bill probably got from me - I got it from a newspaper article
in Sydney in mid 1980's - the cadmium component in super phosphate
fertiliser accumulates in the soil, the sulphuric acid acidifies the soil
and the cadmium mobilises to be taken up by plants - the vegies tested
has 350 times the WHO acceptable cadmium level for human consumption.

Arsenic is a big one on old banana farms around here.
Haven't had a chance to check it out yet but Russ Grayson alerted us to a
series of articles in Sydney Morning Herald on health & environmental
hazards of fertilisers in our food
