That quote was taken from "Spiritual Nutrition and the Rainbow Diet".

>W.Newsome. But I fear it's gonna be difficult.

Unfortunately, he didn't give the specifics for that study reference.

However, I found some other info regarding this subject:

Quoting from

The dithiocarbamates are a group of fungicides including mancozeb, metiram,
zineb and ziram which have a metabolite called ethylene thiourea (ETU). This
breakdown product is a known endocrine disruptor, carcinogen, mutagen and
teratogen, and can concentrate upon processing and heating. In other words,
if you cook a vegetable which has been sprayed with mancozeb (the most
common), you will be increasing the amount of the dangerous metabolite.

Over 60% of the 138 samples of fruit and vegetables analysed for
dithiocarbamates in the latest total diet survey contained them. The 17
fruit and vegetables ranked in order according to occurrence and mean
concentration are: broccoli, cabbage, tomato, celery, lettuce, onions,
cucumber, apples, oranges, mushrooms, potatoes, courgettes, kumara,
nectarines, pears, capsicum and kiwifruit.
