What is particulate matter, and why is it a health concern?
The visible smoke from leaf burning is composed of tiny particles that contain toxic pollutants. If inhaled, these microscopic particles can reach deep into the lungs and remain there for months or even years. Breathing particulate matter increases the chances of respiratory infection, and causes other problems such as coughing, wheezing, chest pain, and shortness of breath. Particulate matter can also trigger asthma attacks in some people.
The visible smoke from leaf burning is composed of tiny particles that contain a number of pollutants. If inhaled, these microscopic particles can reach the deepest regions of the lung and remain there for months or even years. Breathing particulate matter can increase the chances of respiratory infection, reduce the volume of air inhaled and impair the lungs’ ability to use that air. Particulate matter can also trigger asthma attacks in some people. Q: What are hydrocarbons and why are they harmful? A: Hydrocarbons are chemicals that can exist as both gases and solid particles. Because leaves are often moist and burn without proper air circulation, they often burn poorly, producing high levels of hydrocarbons. Some of these hydrocarbons, such as aldehydes and ketones, cause irritation of the eyes, nose, throat, and lungs. A substantial portion of the hydrocarbons in leaf smoke consists of polynuclear aromatic hydrocarbons, some of which are known carcinogens. Q: What is carbon monoxid
