What Is It?

Modified organic chemicals are of great benefit in the dry cleaning , painting, air conditioning, and degreasing industries. However, many have been proven to have harmful effects, including causing cancer. When toxic substances become airborne (toxic air pollutants), emissions from one area can be carried to another area unseen and undetected.

The Air Toxics Laboratory transports scientific measuring instruments out into the neighborhoods in order to to detect and measure airborne toxic substances.

An individual sample can be composited for 24 hours every 6 days at the 5 fixed sites spread throughout the city, and one duplicate is sampled at Kooker Park.  

Monitoring technician at workThe lab can analyze for more than 60,000 organic compounds. It is equipped with an Agilent Technologies 5973N mass spectrometer and Entech Instruments 7200 cryogenic concentrator which, under computer control, collects and concentrates air samples to detect extremely small quantities of organic compounds.

Current Uses

The primary purpose for this system is to collect data on organic compounds that are potentially harmful to the public health, many of which are also a factor in ozone formation.
