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?

ICP VEGETATION

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
