Very interesting project! Is it possible to differentiate between specific anthropogenic Pb sources using Pb isotopes in honey?
Hi Elizabeth, Thanks for visiting/reading the presentation! Sources can be somewhat differentiated using honey, but (as is the case with biomonitors) honey is more useful when used in conjunction with other tools and information. Examples of other helpful info might be: a receptor model with some knowledge of various local point sources, topsoil survey, land use history, etc. Pb isotopes in environmental samples are almost overwhelmingly governed by the [legacy] leaded gasoline mixing line, so deviations from that trend (i.e. via local Pb input sources), are often difficult to tease apart. Further reading: https://www.nature.com/articles/s41893-019-0243-0 https://agupubs.onlinelibrary.wiley.com/doi/abs/10.1029/2020GH000264 Contact me if you have any further questions. -K. Smith

Thanks for sharing your presentation! I was wondering if you could do a similar spatial analysis (source) for other contaminants, like organic persistent pollutants? Pesticides are mentioned in your presentation but didn't see if you have been successful in tracking other pollutant sources with honey. I am asking because in some cities (I live in St Petersburg, FL, USA) there is a boom of local producing honey, but also there is a long tradition of having the perfect lawns by using pesticides, etc.

Interesting project! Have you had the chance to compare the Pb isotopes to recent aerosols or other atmospheric proxies to determine spatial and temporal trends?
