Federal Standards PM 10 PM 2.5 Annual Revoked 15 μg/m3 24-Hour 150 μg/m3 35 μg/m3 In June 2002, the California Air Resources Board (CARB) adopted new, stricter standards for particulate matter that would affect both the coarse as well as fine particulate fraction (Table 2). A source-oriented CMAQ was established for primary particulate matter (PPM). • Source and region contributions to EC, POC and PPM in China were quantified.

Mass and composition in urban environments tend to be divided into two principal groups: coarse particles and fine particles. The barrier between these two fractions of particles usually lies between 1 µ m and 2.5 µ m. •PM (filterable) emission rate = 0.61 lbs/hr = 0.0023 lbs/ton •PM (condensible) emission rate = 0.90 lbs/hr = 0.0033 lbs/ton Example: Site-Specific Stack Test Rate Unit Conversion Particulate Matter (PM) Emission Calculations Mecklenburg County Land Use and Environmental Services Agency Air Quality Division Presented by: Evan Shaw Particulate matter (PM) is a term used to describe the mixture of solid particles and liquid droplets in the air. It can be either human-made or naturally occurring.

6 It’s important to note that wind can carry particulate matter in from geographic regions that may seem far away 6 —for example, during forest fires, here in Manitoba we Particulate Matter (PM) Standards Health-Based Federal and State Standards Based on health considerations, both the state and the federal government set ambient air quality standards for PM10, and more recently, these standards have been revisited to address the health-related concerns regarding PM2.5. Particulate matter may come in different sizes, depending on its components, but they only have two size classifications, which are PM2.5 and PM10. Particulate Matter 2.5. Also referred to as fine particulate matter, particulate matter 2.5 or PM2.5 is named as such because it only measures 2.5 micrometers in diameter, or even less than that.

More 1.1 These particles come in many different size ranges such as coarse, fine and ultrafine. "Fine" particulate matter, as 2.5 PM is referred to by health agencies, means something particularly dangerous to sensitive groups that demands protection. The particulates, and whatever toxins they may be carrying with them, can’t just penetrate your lungs. They can also pass into your bloodstream. Particulate matter, or PM, isn’t just one contaminant. It’s a range of particles of dust, dirt, and liquids that become suspended in the air.

Particulate matter (PM), also known as aerosols, is a mix of fine dust and tiny liquid droplets suspended in the air. Even though much particulate matter is so small as to be invisible to the naked eye, it is possible to see others in high concentrations like smoke from a chimney, a candle, or cigarette. These particles are called PM10 (we say "P M ten", which stands for Particulate Matter up to 10 micrometers in size).
