Neal:
Your comment is true. Notice, however, that these researchers and others
quoted in the article can not provide any data to suggest that these trace
concentrations of chemical substances in biosolids produce any human health
or environmental impacts. These researchers are raising "red flags" about
the presence of these constituents in biosolids hoping to get research $$ to
demonstrate a problem. However, there are no impacts. While analytical
chemistry methods are capable of identifying these constituents in biosolids
or biosolids composts at the ppm, ppb, and ppt levels, the bottom line is
that no one can demonstrate any negative effects on humans, animals, or
vegetation when these biosolids/composts are land applied.
I will be publishing a paper in the November/December time frame that will
suggest that the detection of micro pollutants in biosolids/biosolids
composts is a non-issue and that our time would be better spent on the
issues of pathogens and aesthetic impacts such as odors from biosolids land
application and biosolids composting. I trust that no one in the biosolids
or biosolids composting profession should be losing any sleep over this
article.
Cheers
Alan
