Leland Legacy and NUTRAC

SKC has collaborated with Mickey Leland National Urban Air Toxics Research Center (NUTRAC) to develop the Leland Legacy sampling pump, further advancing personal exposure measurement.

In the United States CongressIn the 1990 Clean Air Act Amendment (CAAA), the non-profit Leland Center was responsible for investigating and researching the health risks faced by the public in air contaminated with toxic gases The Leland Center is a private/public collaborative research institution that leads companies, academia, and government scientists to jointly develop a reasonable peer review toxic air research plan, which is supported by private institutions and the U.S. Environmental Protection Agency (EPA).
