Exposure to Volatile Compounds
Exposure studies reveal that people come into contact with toxic volatile organic compounds and pesticides more indoors than outside. Most people's exposure to breathable particles during the day is higher than ambient levels in t..... read more.
Emissions Samplers
Carbon monoxide measurer uses an electrochemical cell as a gas sensor. The small electric current generated by the cell varies with the ambient level of carbon monoxide. By monitoring this current, an internal microcomputer can ca..... read more.
Sources of Benzene Emissions
Benzene, a volatile organic compound that causes cancer in humans, is quite common. But the sources that produce the greatest quantity of emissions (automobile exhaust and industry) contribute only modestly to the exposure of th..... read more.
