> 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.
