To reduce human health impacts, mining laws in some areas require buffer zones between surface mining operations and populated areas; thus, the effects of PM exposure may be lessened or infrequent ( Aneja et al., 2012 ). Particulate Matter (PM) Standards - Table of Historical PM NAAQS History of the National Ambient Air Quality Standards for Particulate Matter During the Period 1971-2012. Final Rule Primary/ Secondary Indicator Averaging Time Level Form; 1971 36 FR 8186 Apr 30, 1971: Primary: TSP : 24-hour: 260 Sulphur oxides (SOx) and Particulate Matter (PM) – Regulation 14 SO x and particulate matter emission controls apply to all fuel oil, as defined in regulation 2.9, combustion equipment and devices onboard and therefore include both main and all auxiliary engines together … PPM means Primary Particulate Matter.

Because particles originate from a variety of activities and processes, their chemical and physical compositions vary. The NAAQS for PM10 replaces older particulate standards based on total suspended particulates (TSP) in the atmosphere. In 1987, the EPA replaced the TSP standards because particulate matter of less than 10 microns diameter contained in a cubic meter of air (mg/m3) that can be inhaled deeply into the lungs has greater health effects than larger Federal Standards for Particulate Matter. 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).

Health Effects of PM: Inhalation of particulate pollution can have adverse health impacts, and there is understood to be no safe threshold below which no adverse effects would be anticipated [1] . 2016-09-12 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 … Particulate matter (also known as particle pollution or PM), is a complex mixture of solid particles and liquid droplets in the air. Often characterized according to size, particulate matter is made up of a number of different components, such as: View the latest PM 2.5 (Fine Particulate Matter) data. Instructions on how to use the map are below.. Please note that air quality data may be missing for many reasons that are beyond our control including local power or communications outages, instrument calibration cycles or failure.

It can be either human-made or naturally occurring.
