Kilogram

The kilogram or kilogramme (symbol: kg) is the base unit of mass in the International System of Units (SI), and is defined as being equal to the mass of the International Prototype of the Kilogram (IPK, also known as "Le Grand K" or "Big K"), a cylinder of platinum-iridium alloy stored by the International Bureau of Weights and Measures at Saint-Cloud, France.

National Exposure Research Laboratory

The U.S. Environmental Protection Agency's National Exposure Research Laboratory (NERL) is a national laboratory that conducts research and development to find improved methods, measurements, and models to assess and predict exposures of humans and ecosystems to pollutants and other conditions in air, water, soil, and food.

Portable emissions measurement system

A portable emissions measurement system (PEMS) is a vehicle emissions testing device that is small and light enough to be carried inside or moved with a motor vehicle that is being driven during testing, rather than on the stationary rollers of a dynamometer that only simulates real-world driving.

Toxic Substances Control Act of 1976

The Toxic Substances Control Act (TSCA) is a United States law, passed by the United States Congress in 1976 and administered by the United States Environmental Protection Agency, that regulates the introduction of new or already existing chemicals.
