What is PM10 particulate matter?
What is PM10 particulate matter?
Using a nationwide network of monitoring sites, EPA has developed ambient air quality trends for particle pollution, also called Particulate Matter (PM). PM10 describes inhalable particles, with diameters that are generally 10 micrometers and smaller.
How does PM10 affect human health?
PM10 particles are so small that they effectively act as a gas. Exposure to high concentrations of PM10 can result in a number of health impacts ranging from coughing and wheezing to asthma attacks and bronchitis to high blood pressure, heart attack, strokes and premature death.
What is PM10 particulate pollution?
PM10 is any particulate matter in the air with a diameter of 10 micrometers or less, including smoke, dust, soot, salts, acids, and metals. Particulate matter can also be formed indirectly when gases emitted from motor vehicles and industries undergo chemical reactions in the atmosphere. Various sources include: 4,5.
What are particulates in the lungs?
In the workplace, most often the term “particulates” refers to particles, dust, mist or fume that has become suspended in the surrounding air. The hazard with airborne particulates is that a person may breathe in the chemical that may have ill effects on an individual’s health.
What causes high PM10?
PM10 also includes dust from construction sites, landfills and agriculture, wildfires and brush/waste burning, industrial sources, wind-blown dust from open lands, pollen and fragments of bacteria.
What is a safe level of PM10?
Technically, there isn’t a safe level of PM10, as any amount of particulate matter in your air isn’t a good thing. Keeping your exposure to PM10 concentrations below 54.0 µg/m³ is the best way to prevent any short or long-term health effects from developing.
What does particulate matter do to the body?
Health studies have shown a significant association between exposure to particle pollution and health risks, including premature death. Health effects may include cardiovascular effects such as cardiac arrhythmias and heart attacks, and respiratory effects such as asthma attacks and bronchitis.
Why particulate matter is bad?
Particulate matter contains microscopic solids or liquid droplets that are so small that they can be inhaled and cause serious health problems. Some particles less than 10 micrometers in diameter can get deep into your lungs and some may even get into your bloodstream.
What are some examples of PM10?
Some common examples of PM10 are:
- Mold spores.
- Bacteria.
- Dust.
- Smoke.
- Airborne viral particles.
What’s the difference between PM2 5 and PM10?
To answer these questions, the main difference between PM2. 5 and PM10 is size. So, PM10 refers to particles with an aerodynamic diameter smaller than 10 μm, and PM2. 5 refers to particles with an aerodynamic diameter smaller than 2.5 μm.
How much PM10 is safe?
What is pm 10 pollutant?
Common sources of PM 10 particles include: dust from unsealed roads smoke from fires sea salt car and truck exhausts industry.
What are the causes of particulate matter?
Particulate matter particles can either originate from antropogenic (caused by humans) or from natural sources. Volcanic eruptions, soil erosion, sea salt or the import of desert sand are all examples of possible sources of particulate matter.
What is PM10 pollutant?
Particulate Matter (PM10 and PM2.5) Pollution. Particulate matter, sometimes referred to as particle pollution or PM, is a complex mix of very small particles, water vapor, and gases. Common small particles can include lead, dust, dirt, and sand.
What is PM10 air pollution?
Using a nationwide network of monitoring sites, EPA has developed ambient air quality trends for particle pollution, also called Particulate Matter (PM). PM10 describes inhalable particles, with diameters that are generally 10 micrometers and smaller.
