PM2.5 a name you must know…
What is PM2.5?
Particulate Matter (PM) 2.5 is a term used to describe the mixture of solid particles and liquid droplets in the air with a diameter of 2.5 micrometers or less, small enough to invade even the smallest airways.
Where does PM2.5 come from?
Outside, fine particles primarily come from car, truck, bus and off-road vehicle exhausts. Other operations that involve the burning of fuels such as wood, heating oil or coal and natural sources such as forest and grass fires. Fine particles also form from the reaction of gases or droplets in the atmosphere from sources such as power plants.
Indoor, some sources of fine particles are tobacco smoke, cooking, burning candles or oil lamps, and operating fireplaces and fuel-burning space heaters.
How can PM2.5 affect my health?
Particles in the PM2.5 size range are able to travel deeply into the respiratory tract, reaching the lungs. Exposure to fine particles can cause short-term health effects such as itchy eye, throat and lung irritation, coughing, sneezing, runny nose and shortness of breath. Exposure to fine particles can also affect lung function and worsen medical conditions such as asthma and heart disease. Scientific studies have linked increases in daily PM2.5 exposure with increased respiratory and cardiovascular hospital admissions, emergency department visits and deaths. Studies also suggest that long term exposure to fine particulate matter may be associated with increased rates of chronic bronchitis, reduced lung function and increased mortality from lung cancer and heart disease. People with breathing and heart problems, children and the elderly may be particularly sensitive to PM2.5.
VOC another name you must know…
What is VOC?
Volatile Organic Compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short and long-term adverse health effects. Concentrations of many VOCs are consistently HIGHER indoors than outdoors.
Where does VOC come from?
Organic chemicals are widely used as ingredients in household products, such as paints, varnishes, wax, air fresheners, cleaners, disinfectants, cosmetics, hobby products, and pesticides. All of these products can release organic compounds while you are using them and sometimes even when they are stored.
How can VOC affect my health?
Exposure to VOC can cause short-term health effects such as red eyes, stuffed up nose, throat and lung irritation, coughing, sneezing, runny nose and shortness of breath. In some cases, headaches, loss of coordination and nausea are also often seen.
