PM2.5: Particulate matter, or PM, is a mix of particles and droplets in the air. PM varies in shape and size, but those of 10 micrometers in diameter or smaller can adversely affect your health because they can be inhaled. PM 2.5 refers to fine particulate matter—that with a diameter of two-and-one-half microns or less.
Sufficient exposure to PM2.5 can irritate the eyes, nose, throat, and lungs, leading to allergy-like symptoms and shortness of breath in otherwise healthy people. It can also exacerbate existing medical problems, such as asthma and heart disease. The World Health Organization considers PM2.5 the world’s single biggest environmental health risk.
Indoor PM2.5 levels can be influenced by outdoor sources like vehicle exhaust, wildfires, and power plant emissions. But many indoor activities produce PM2.5 as well: Cooking, burning fireplaces, and smoking are just a few common sources.Code: Select all
Formaldehyde (HCHO) and volatile organic compounds (VOC) are certainly the most common and the most dangerous substance groups with regard to indoor air exposure.
volatile organic compounds, gases emitted from a variety of materials that can have short- and long-term health effects. According to the Environmental Protection Agency, concentrations of many VOCs can be up to 10 times higher indoors than outdoors.
Sources of VOCs include many common household products, including hairspray, cosmetics, cleaning fluids, disinfectants, paints, and varnishes. Burning fuels like wood and natural gas also produces VOCs. Formaldehyde is onne of the most common VOCs and can be found in many building materials, including plywood, glues, and insulation. Formaldehyde is also used in some drapes and furniture fabrics. You can read more about formaldehyde and its sources in this article from the U.S. Consumer Product Safety Commission.
Short-term exposure to the low levels of VOCs can cause throat irritation, nausea, fatigue, and other minor complaints. Long-term exposure to high concentrations of VOCs has been linked to more severe respiratory irritation as well as liver and kidney damage. Products can emit VOCs even when they’re in storage, though to a lesser extent than when they’re actively being used.
