Hi,
Whilst there is certainly a theoretical risk in practice the EA
report in 2014* seems to show only a marginal risk for allotments.

Subject: PAS 100:2011 Lead
PTE and Allotment Lead C4SL
Hello List
We are helping out with a
local community garden project. They are looking to use Certified
PAS100 compost materials.
The PAS100:2011 specification includes a
upper limit lead PTE (potentially toxic element) quality standard for
general use of 200 mg/kg.
Has anybody had any dealings/discussions
with WRAP, AfOR or BSI to see how this Lead PTE sits with the allotment
C4SL of 80 mg/kg?. It sits well with the Residential C4SL with home
grown produce of 200 mg/kg.
I'm not particularly concerned about the
lead PTE at 200 mg/kg for compost, but just interested if the allotment
80 mg/kg C4SL has been raised with WRAP, AfOR or BSI or whether they
have already officially commented (couldn't find anything on their
websites).
(should I really be posting this on 1st April !)
Thanks in
advance
Chris Dainton
