tasks was to analyse the water we were drinking. He soon arranged for a
regular delivery of water to us, for, amongst other impurities, he found
there was a fair amount of arsenic the water garnered off the roof, so I
would not drink yours without careful analysis by a professional.

Question - Do people often die of arsenic poisoning?

Answer - No only once!.

Bill

Arsenic is a cumulative poison so the answer is yes. You die by
degrees.

Come now Harry read what is written. No one dies often :-)

A common way for gardeners to get arsenic is by burning old pressure
treated fence posts in the garden. The arsenic gets into the soil &
thence into their vegetables.

Also present in smoke and soot from burning coal.
Gardeners used to put soot on the garden. Some still do.
