[HubbardBrookCOS] Long-term foliar chemistry--which elements are key?

[Bailey, Scott -FS]

A number of the elements listed by Peter and Linda are much more prevalent in the sample processing environment than they are in foliage. Pb, Hg, Al, Fe, Zn, Cu are probably among these. These will require different protocols than what has been used for foliar monitoring in the past. I am not sure what the purpose is of this proposal. If it is just general environmental monitoring, it may be easier and give more information to monitor some of these elements in soil rather than foliage.  Rich Hallett has done a lot of work to refine procedures for measuring Al in foliage and would be a good resource for that element. He found several sources of Al contamination in the lab that were swamping out Al in foliar digests.

I don't think it is essential, but lead and mercury have great societal interest and the long-term record at Hubbard Brook is an excellent tracer of efforts to control atmospheric pollution.

Dear Associates:

As we work on compiling the long-term foliar chemistry record, we will need to fill in gaps of parameters that were not measured by analyzing (or re-analyzing samples). I am writing to you to get your feedback on what elements you consider essential or most important for the long-term dataset.
Below are the ones that have most frequently been measured. We will certainly include the bolded analyses. Please weigh in if you have elements in addition to the bolded ones things that you would like to have data for.

Thanks,

Linda
