[CANUFNET] Safety Testing of Fruits & Nuts/heavy metals +othercontaminant testing.

[For Trees Company Ltd.]

Hello Andrea,
I concur with Mark. Extensive testing of trees and tree fruit growing in a 
subdivision in Calgary built on the former site of an oil refinery showed 
lead and hydrocarbon traces far below any health concerns, even though lead 
contamination was measurable in the soil.

Andrea,

Beverly Hale from Guelph U has done a lot of work on vegetation uptake.
You can also try contacting Mike Payne at OMAFRA.
In my experience fruit trees do not uptake many contaminants well and
even those that are uptaken well are often at low concentrations by in
individual fruits.  I hope this was helpful.

Dear Canufnet folks,

GreenHere has been using Andy Kenney's tree inventory in its taget
area for the past 2 years, and there are almost 500 fruit trees -
pears, plums, apricots, apples, serviceberries, peaches, cherries,
walnuts, hackberry, butternut, etc.

Food security/hunger and nutrition issues for the local communities
could be partially addressed through the creation of a community fruit
& nut harvesting program. (25% of families live on incomes of less
than $20k.)

However, the area is mixed industrial/residential with 3 railway
corridors running through it.  Air and soil contamination is a concern
with regards to the safety of fruit to be harvested from the area.

Does anyone have any experience with testing for industrial
contaminants in fresh fruit and/or what are the threshhold limits for
certain contaminants i.e. heavy metals like lead and mercury?

Any guidance or expert referrals that you may have with regards to
ensuring the safety of food harvested and/or suggested tests to do
would be most appreciated.

Yours truly,

Andrea Dawber
