[Pharmwaste] chemicals in toothpaste and elsewhere

[Ronald Ney]

I just wanted to share information and am concerned because of the following.

Thousands of chemical and biological pollutants are not regulated when
disposed of in the environment or used in the environment and this is
a ticking time bomb. Safety cannot be judged on one chemical or one
biological alone. Exposure to these chemicals and their degradation
products, and/or biologicals in consumer products, in the environment,
etc. can present a risk to all. Safety of these chemicals and their
degradation products, and biologicals is unknown because the
aggregate, synergistic, antagonistic, co-metabolism and
co-biometabolism effects are never mentioned or studied to any extent
and are not used in risk assessments?  In other words, the total risk
picture is unknown for adults, children and fetuses, and the
environment.

I based this on my past experience.
1.	I have reviewed about 3,000 reports for pesticide petitions for
tolerance (chemical residues in crops), rotational crops, planting
restrictions, etc. I wrote many data requirements for this under FIFRA
(before USEPA).
2.	I have reviewed about 500 reports for environmental chemistry data
on fate and transport of pesticides in air, water, soil, plants and
animals. These data requirements were written and started by me.
3.	Almost all the data were validated via radiotracer studies.
