[Terrapreta] Using Activated Charcoal to Inactivate Agricultural Chemical Spills

[shengar at aol.com]

Inactivating Pesticide Spills

"If a pesticide is spilled accidently, if the wrong
pesticide is applied, or if a pesticide is applied at
an excessive rate, the best solution is to apply a
material that will adsorb or inactivate the pesticide. Once the pesticide has been adsorbed, it is
biologically inactive and cannot cause environmental contamination by running off in surface
waters or leaching into groundwater.

Activated charcoal (activated carbon) is the
universal adsorbing material for most pesticides.
Powdered activated charcoal is made up of very
small carbon particles that have a high affinity
for organic chemicals such as pesticides. Activated charcoal has a large surface area to which
organic molecules can bind. When it is applied to
pesticide-contaminated soil, the pesticide
molecules are attracted to the charcoal particles
and bind to them when they come into contact"

"Activated charcoal is manufactured by
many companies, such as ICI Americas, Inc. and
West Virginia Pulp and Paper Company. It is
available through your local agricultural chemical
dealer. Two commonly used agricultural 
carbons are Gro-Safe (ICI Americas) and NuChar
S-A (Westvaco). Activated charcoal usually costs
about $1 per pound or less."





Hi All, 

I thought this was pertinent? to the post concerning? biochar? &? Roundup? a few weeks ago.



I
thought I would send the above Activated charcoal producers a post? to
make sure they were apprised of the current progress in TP soils
technology in hopes to get them interested.




Cheers,

Erich
