What are the significant sources now we have unleaded petrol?

I have to ask whether using grey water collected from lead flashed
roofs could contribute significant lead to, say, the vegetable plot?


Almost certainly. Aren't brassicas hevay metal concentrators?

In cattle (apparently - for I certainly didn't know this):

"Feed contamination is also a potential problem, indeed contaminated
rice bran from Burma was the primary source of the last major outbreak
of lead poisoning in the UK in 1989."

And mercury in tuna. Of course I eat tuna three times a day - don't you?



I keep brassica consumption down because they are goitrogens. :-)

And it seems unlikely that we will be importing Burmese rice bran for a
while.

Without the mercury, how would you know when it is cooked?

Hypothyroidism is a seriously debilitating condition with an insidious
onset.
Although common it frequently goes undiagnosed.
