Period 5 APES
Define : PAHs are a group of chemicals that are formed during the incomplete burning of coal, oil, gas, wood, garbage, or other organic substances, such as tobacco and charbroiled meat. There are more than 100 different PAHs.
Purpose : PAH compounds are a generally hazardous class of organic compounds found in petroleum and emissions from fossil fuel and conversion processes.
PAHs are one of the most widespread organic pollutants. In addition to their presence in fossil fuels they are also formed by incomplete combustion of carbon-containing fuels such as wood, coal, diesel, fat, tobacco, and incense.
Breathing: breathing smoke, auto emissions or industrial air. Most exhausts contain many different PAH compounds. People with the highest exposures are smokers, people who live or work with smokers, roofers, road builders and people who live near major highways or industrial sources.
Touching: can be absorb through physical contact. Exposure can come from handling contaminated soil or bathing in contaminated water. It occurs when the person is not cleansed.
Drinking/Eating: Charcoal-broiled foods, especially meats, are a source exposure. Shellfish living in contaminated water may be another major source of exposure. Drinking water may also contain the toxin.
Sometimes vegetables do not contain it either.
High Exposure can cause Lower IQ & Childhood asthma
A 52-year-old man comes to your office for a health evaluation, his first in 3 years. The patient has worked at a coal tar manufacturing plant for the past 34 years. He has been exposed to varieties of PAH’s & as a result many side affects has been happening to him.
Solution: He is put under treatment
And care till further notice, so far
He is only on medication.“Dyspnea, weight loss, and weakness in a 52-year-old male coal tar manufacturing plant worker”
