        What is the Difference in Particulate Matter PM2.5 and PM10?

        What is the difference between pm2.5 and pm10?

        What is Particulate Matter?

        Airborne particulate matter (PM) is not a single pollutant, but rather is a mixture of many chemical species. It is a complex mixture of solids and aerosols composed of small droplets of liquid, dry solid fragments, and solid cores with liquid coatings. Particles vary widely in size, shape and chemical composition, and may contain inorganic ions, metallic compounds, elemental carbon, organic compounds, and compounds from the earth’s crust. Particles are defined by their diameter for air quality regulatory purposes. Those with a diameter of 10 microns or less (PM10) are inhalable into the lungs and can induce adverse health effects. Fine particulate matter is defined as particles that are 2.5 microns or less in diameter (PM2.5). Therefore, PM2.5 comprises a portion of PM10.

        What is the Changing Risk and Burden of Wildfire in the United States?

        What is the Changing Risk and Burden of Wildfire in the United States?

        A new study published by the Proceedings of the National Academy of Sciences of the United States of America (PNAS) is predicting a grim future for wildfires and the resulting toxic smoke. 

        Over the past four decades, burned area from wildfires has roughly quadrupled in the United States. This rapid growth has been driven by a number of factors, including the accumulation of fuels due to a legacy of fire suppression over the last century and a more recent increase in fuel aridity shown for the western United States), a trend which is expected to continue as the climate warms.

        These increases have happened parallel to a substantial rise in the number of houses in the wildland–urban interface (WUI). Using data on the universe of home locations across the United States and updated national land cover maps, we update earlier studies and estimate that there are now ∼49 million residential homes in the WUI, a number that has been increasing by roughly 350,000 houses per year over the last two decades.

        Australian Bushfire Smoke Blankets Sydney

        Australian Bushfire Smoke Blankets Sydney

        Smoke over Sydney, Australia, caused by raging bushfires, has become so thick that it is setting off smoke detectors in the central business district, reported South China Morning Post on December 10.

        Residents in parts of eastern Australia abandoned their homes on Tuesday as soaring temperatures and strong winds threatened to fan bushfires in a giant blaze north of Sydney, the country's biggest city.

        Air quality in parts of Sydney plunged as the city awoke on Tuesday to another thick blanket of smoke, disrupting transport services and prompting health warnings...

        NEW Air Pollution App is also Wildfire Warning System

        Breezeometer Air Pollution and Wildfire Warning App

        Breezometer, a free app that offers real-time air quality data, announced that it will be offering fire alerts to help users determine if they're in harm's way. Wildfires are becoming larger and more frequent than ever, and can have lingering effects on the air quality. The fire alerts are based on information from NASA and local sources and -- combined with the app's own algorithms -- can determine which direction the smoke is traveling and its impact on air quality.

        Through the app, users who live between 20 to 60 miles of a wildfire can receive timely updates on its progress. Wildfire pollution was only recently discovered to travel...

        How Air Pollution Effects Your Pets

        Effects of Air Pollution on Pets and Dogs

        People aren't the only ones who can suffer ill effects from exposure to air pollution. Many pet owners have concerns about the effects of air pollution on their animals, and scientists are beginning to study the potential risks for pets that have exposure to air pollution.

        Research has confirmed the dangers of air pollution for humans. People who are exposed to excessive air pollution have an increased risk of developing respiratory issues such as wheezing, coughing, shortness of breath, and chest tightness. Cardiovascular disease is another potential health issue connected to exposure to air pollution. Those with pre-existing cardiovascular disease as well as elderly people and young children may even be at risk for premature death from pollution exposure..

        Urban Air Pollution and Pets

        Sources of Air Pollution

        Air pollution originates from many different sources. Fumes from wildfire smoke, vehicle traffic, power plants, construction, the burning of coal and gasoline. Homes can be filled with pollution from sources such as wood-burning stoves and fireplaces, tobacco smoke, and cooking. Pets living in urban areas have a higher exposure to and risk from smog and exhaust pollutants, while animals living in rural areas may be exposed to chemicals due to the spraying of herbicides, fungicides, and insecticides.

        Scientific Studies about Air Pollution

        Studies have shown that pets living in homes with cigarette-smokers have increased health risks, perhaps even greater than those for humans living in the same homes. This is because pets spent more time near the floor, where smoke concentrations are higher. Cats exposed to secondhand smoke have been shown to have reduced lung function when compared to felines living in smoke-free homes, according to scientific research. Scientists are also exploring links between common indoor activities such as smoking and the use of cleaning products and certain cancers in dogs.

        Pets are also at risk from outdoor air pollution. In a recent study of dogs in Mexico City, scientists examined the brains of local dogs to compare them with the brains of dogs in cities with less pollution. The brains of dogs living in Mexico City showed inflammation, amyloid plaques, and neurofibrillary tangles, which are associated with Alzheimer's disease in humans.

        Another study conducted by the University of Massachusetts and the Tufts University Cummings School of Medicine involved 700 dog owners and their use of pesticides. The results showed that about a third of the dogs had canine malignant lymphoma, a type of cancer. The study also showed that the dogs had a 70 percent higher chance of developing lymphoma if the owners used pesticides in their yards.

        Affect of Air Pollution on Animals and Pets

        Cats have also been found to be more likely to develop asthma when exposed to indoor or outdoor pollutants. Felines living in homes where a wood-burning fireplace is in use or smoking occurs are often found to have a marked decrease in lung function.

        Taking Steps to Reduce Pets' Exposure to Air Pollution

        Because many pets spend the majority of their time indoors or in their yard, it's important for owners to take steps to minimize exposure to air pollution both inside and out.

        • Change air filters often.
        • Vacuum frequently to remove hair and other pollutants.
        • Avoid smoking indoors.
        • Choose chemical-free cleaning products when possible.
        • Reduce carbon emissions when possible by carpooling, taking a bus, or biking.
        • Choose areas for outdoor exercise of pets where the air is cleaner (away from highways).
        • Use chemical-free products in the yard whenever possible.
