It depends on the form of Zinc.
Lonny, do you know?
The low amount of eelgrass we have been seeing for several years now is the longest stretch of time that the eelgrass population has been depleted.
Does the EDTA chelation have a preference for Cd versus other heavy metals (e.g. Zn or Pb?)
Earl, Do I know what?
Why it’s gone?
I've been studying the eelgrass in the St. Johns for 10 years now.
So what happened to it?
I have not found anything scientific except for some speculation that it dies back after long periods of heavy rains.
If you look at the "State of the River" Report on St. Johns River they have info on heavy metals in fish.
Thank you. I coundn't find any on the river from Federal Point the the south end of Lake George last year. I have not been on the river since October so it might be coming back
The USGS has a "My Watershed" website has advisories on several fish species caught in the St. Johns.
Longin, thanks. Good source to know about.
AA tests are very expensive.
