Just what is the effect of ash from the #NorthBayFires landing on plants in our gardens? Is the food we’ve grown safe to eat?
Today I went to an event about the “Citizen Science” produce sampling project. Here’s a link to an original invitation for sites to get involved. It was really good but I can’t type up all my notes. Basically, very little is known about the effects of fires on garden/farm produce. A graduate student was “voluntold” by a produce project founder to look into air quality issues from the time of the fires so that any toxins in samples could be compared to the air quality during that time. The samples are from a nice smattering of places around Sonoma County (and, I’m sure, beyond). There is a basic list of things that are common chemicals in houses, furniture, clothes, etc, and there is a list of things they’ll test for. I seem to remember lead, PAH’s, lead, arsenic, cadmium, and cobalt. PS, more research is needed about the effects of flame retardants and the Phos-Chek that was applied.
There is at least one group doing bioremediation by putting (mushroom) inoculated straw wattles in/around streams. There will also be a project that will do soil sampling (I think they said it will be linked to the results of the produce test? or at sites that were sampled?). It sounds like sites that had more than one type of greens, ie lettuce and kale, will be prioritized. Someone from UC Davis has already collected ash from impacted sites to examine with mass spectrometry. “Science is amazing!” as the kids from the Pokemon cartoon TV show said.
I still need wood chips. Now I’m nervous about sources (were the trees from burned areas? was phos-chek dropped on them? etc) and about my compost in the future- are people bringing fire-damaged plant materials to the big composting sites? Should that stuff go to a toxic waste disposal site? It was mentioned that adding organic material to the soil is a key way to mitigate the effects of, or even basically break down some of the bad compounds into things that are not as bad. So I need to keep covering my soil 🙂
Funding for the produce project is yet to come. They figured out that each site’s produce testing will cost some $2000. There is a Giving Tuesday campaign to raise money for the produce testing project (although the project is not mentioned on the link I’m including?). The goal for this Tuesday is $2000 to be able to get one site’s samples tested, but I would like to think they will raise more. They will also be requesting grant money. Please help support the project if you can. Please comment here or contact the folks in the first link to find out more about the project.
Meanwhile, in my garden…
