Note change of scale to 100 leaves per plant
ICP VEGETATION
For data analysis purposes, a single number for ‘injury’ is useful
Weighting for severity of injury
Suggestion:
A: 1 x % leaves with 1-5% injury
B: 3 x % leaves with 5-25% injury
C: 5 x % leaves with >25% injury or dead
‘Injury score’ = A + B + C

• Injury not related to AOT40
• Plants with a lot of injury don’t have as many seeds
• Exposure results at an individual site are linear
• More data needed to further investigate this – flux?

In broad agreement with the ‘crops’
group bean parameterisation
ICP VEGETATION
• Exposure duration: 58 – 110 days (standardise??)
• Start date: 4th May – 11th August (standardise further??)
• Pot size??
• Soil mix: Variable (‘good quality’ and nutrients needed??)
• Germination was good at all sites
• Some batches died for unidentified reasons
Final thoughts
• Some batches died for unidentified reasons
• Some sites didn’t have nearly as much injury as expected – why?
• Some sites showed lots of injury on R – is this ozone or something else?
• Is there an interaction with other pollutants e.g. NOx?
• Can get good linear relationships with exposure studies at individual sites
• More comprehensive dataset needed – investigate fluxes
