CHAPTER Introduction Table of Contents Introduction The EPA (Environmental Protection Agency) conducted a study over the last 25 years (1975-2000) and determined that 107 measurable air pollutants, specifically carcinogens, exist in working environments. Combined with the advent of closed windows, modern office buildings and various cleaning solvents, the outcome has been energy efficient buildings and homes which contain levels of carcinogens.
Page 12: Particulate Sampling (Aerosols/Dust Vapors)
Introduction Particulate Sampling (Aerosols/Dust Vapors) Particulate Sampling (Aerosols/Dust Vapors) The EVM is a portable-area monitoring instrument with a laser-photometer that measures and stores concentration levels of airborne-dust over time. It is designed to measure and help you identify the air pollutants, existing as matter (gases and aerosols) in the environment.
Page 13: Particulate Sizes
Introduction Particulate Sampling (Aerosols/Dust Vapors) Particulate Sizes Aerosols and gases are experienced in industrial processes, workplaces, and in everyday life. Keeping in mind that inhalable dust is 100 microns and smaller, this dust is usually filtered through the hairs and membranes in your sinuses.
Page 14: Particulates And Cut-Point
Gas Sensors Sampling Particulates and Cut-Point Particulates and Cut-Point In consideration of how the size of particulates affect the human body, it is important to select a particulate size cut-point. Essentially, the particle size selector on the EVM is a top-mounted rotary impactor.
