Air Pollution Study: The Effect of Ozone on the Lung

2016-02-04 18:08:24 | BioPortfolio


The purpose of the study is to better understand the mechanisms of lung injury from ozone exposure. Subjects will participate in two exposure sessions: filtered air and 0.2 ppm ozone. Subjects will be asked to produce sputum through coughing after each exposure. The samples will be analyzed for macrophage activity.


Subjects will be asked to come to the Rutgers EOHSI clinical center (Piscataway, NJ) for 5 study visits. A physical exam to determine eligibility will be done at the first study visit. If the subject is healthy and able to produce a sputum sample, he/she will then be scheduled for 2 3-hour exposure visits. One exposure will be to clean air and the other exposure will be to 0.2 ppm ozone. During the exposures, subjects will be requested to ride an exercise bicycle intermittently (approximately every 15 minutes). A follow-up visit for sputum collection will be scheduled either 24, 48, or 72 hours after each exposure visit. Blood, urine, and exhaled breath samples will also be collected at each visit.

Medical and Biotech [MESH] Definitions

A shift in the balance between production and destruction of STRATOSPHERIC OZONE that results in a decline of the amount of OZONE in the lower stratosphere.

Ozone in the Earth's stratosphere. It is produced continuously by the action of solar ULTRAVIOLET RAYS on oxygen in the stratosphere. The stratospheric ozone (especially at the ozone layer) blocks much of the solar UV radiation of wavelengths of 320 nanometers or less from being transmitted to lower ATMOSPHERE of the Earth.

Water pollution from a variety of diffuse sources carried over or through the ground and into water sources such as LAKES; RIVERS; WETLANDS; coastal waters; and GROUNDWATER. Such diffuse sources include roadways and parking lots (GASOLINE; HEAVY METALS; and motor oil), lawns or agricultural land (excess FERTILIZERS, livestock excrement, and PESTICIDES), landfill seepage, and construction sites (chemicals and trash used in construction processes).

Substances used to clean dentures; they are usually alkaline peroxides or hypochlorites, may contain enzymes and release oxygen. Use also for sonic action cleaners.

Examination of foods to assure wholesome and clean products free from unsafe microbes or chemical contamination, natural or added deleterious substances, and decomposition during production, processing, packaging, etc.
