Scientific & Technical Support: Chemisty - Residue Analysis
Residue chemistry guidelines monitor the safety of chemical use in human
food and animal feed, and attempt to assess the dietary risks associated
with chemical use. While residue chemistry is a critical element
to chemical and
pesticide registration, its data includes far more than information on the
magnitude of residues in crop commodities. TSG’s scientists have years of
experience designing, monitoring, reporting and defending metabolism,
residue,
environmental fate and transport studies to meet world-wide
regulatory requirements. We have expertise in method choice and data review
for any project that involves chemical measurements, beginning at the
definition phase and continuing through sampling, analysis and reporting.
Our consultants have broad experience and a varied perspective in
developing residue chemistry data that not only meets specific guidelines,
but directly addresses the regulatory concerns on which guidelines are
based.
We assist
in the following:
▲
Determining the nature of the residue studies in crops and, if applicable,
in
livestock
▲
Ensuring stability of field-incurred residues during storage prior to analysis
▲
Validating analytical methods with
– Incurred radio-labeled residues
▲
Determining residues in
– Water, fish and irrigated crops
– Confined and field rotated crops
– Processed commodities
Determining residues resulting from use of
pesticides in food-handling
establishments
If necessary, we can respond to agency concerns
regarding the conduct and outcome of required studies used to support
information on the concentration of residues in crop and livestock
commodities.
