Evaluating a chemical’s environmental fate is necessary to determine the extent
of
exposure and impact on the environment. TSG’s scientists offer 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.
TSG’s staff provides expert knowledge for compliance
with Canadian, U.S. and EU Good Laboratory Practices (GLP), clearance of food
ingredients and indirect food additives under agency regulations, compliance
with CEPA, TSCA and REACH specifications on testing of
new chemical products,
and litigation support in matters involving environmental contamination and
possible liabilities of chemical products affected by
Proposition 65 in
California.
Our consultants work with clients to determine the desired
label use
recommendations, and design comprehensive field programs that will achieve
this goal. As a recognized leader in the practical application of GLP to
regulatory studies, TSG’s scientists conduct independent study audits and
provide training in GLP compliance on an industry-wide basis. Our staff
includes individuals who have direct experience in GLP from industrial and
regulatory backgrounds, and this perspective forms an integral part of every
field study designed and managed by TSG.
Our scientists coordinate
all aspects of field regulatory studies, from design and protocol
development to implementation and reporting. With a thorough knowledge of
study results coupled with a well-developed understanding of how the conduct
and presentation of a study affect its interpretation, TSG’s staff
implements, monitors, prepares and reviews study reports to ensure
registration. Since TSG's expertise extends far beyond simple field studies,
our staff maintains a global perspective. By properly setting study
priorities and schedules, we ensure effective oversight and timely study
completion. Our consultants guide a study throughout all phases, including
reviewing findings and producing quality results that are acceptable to
regulatory agencies.
By integrating the planning, execution and
outcome of field studies into the overall registration strategy, each field
program is considered one part of a comprehensive strategy for each product.
This helps TSG’s consultants offer a unified data package to the agencies,
which can accelerate the registration process.

TSG provides comprehensive product registration services, from determining data obligations and developing compliant labels, to compiling and submitting the registration application.
The goals of EPA's TSCA IUR program are to collect quality screening-level, exposure-related information on chemical substances in commerce in the United States and to make that information available for use by EPA and the public. The IUR data are used to support risk screening, assessment, priority setting and management activities at EPA and constitute the most comprehensive source of basic information on chemicals in commerce available to EPA.
TSG has offices throughout North America and Europe, including Sacramento, CA, Washington, DC, Canada, United Kingdom, Spain and Slovenia. Through these locations and our affiliates, TSG works with companies in 36 countries worldwide including China, Japan, Australia, New Zealand and Latin America.
REACH (Registration, Evaluation, Authorization and restriction of Chemicals) is an EU Regulation that came into effect on June 1st, 2007, imposing strict guidelines on the manufacture or import of chemicals, preparations and articles in or to the EU.
Drinking Water and Toxic Enforcement Act of 1986, better known as Proposition 65, was approved by voters to address the growing concerns about exposure to toxic chemicals. Proposition 65 requires California to publish a list of chemicals, updated at least once a year, known to cause cancer, birth defects or other reproductive harm. Proposition 65 also requires California businesses to post notification about significant amounts of chemicals in the products they sell, in their homes or workplaces, or that are released into the environment.
