<\/p>\n\n\n\n

High levels of both PM2.5 and PM10 in the air can be harmful to your health, especially when you’re exposed to them over a long time. That’s why there are regulations and guidelines in place to limit the amount of these particles in the air, helping to keep the air cleaner and protect your health.<\/p>\n\n\n\n

\"What<\/figure>\n\n\n\n

What are PM2.5 and PM10?<\/h2>\n\n\n\n

PM2.5 (Particulate Matter 2.5): These are extremely small airborne particles with a diameter of 2.5 micrometers or smaller. They are about 30 times smaller than the width of a human hair. PM2.5 particles can stay suspended in the air for a long time and are small enough to be inhaled deep into your lungs. They can come from sources like vehicle emissions, industrial processes, and even natural sources like dust and pollen.<\/p>\n\n\n\n

PM10 (Particulate Matter 10): These are slightly larger particles with a diameter of 10 micrometers or smaller. While they are larger than PM2.5, they are still very small and can also be inhaled into your lungs. PM10 particles come from similar sources as PM2.5, including dust, vehicle emissions, and industrial activities.<\/p>\n\n\n\n

World Health Organisation<\/h2>\n\n\n\n

The World Health Organization (WHO) provides air quality guidelines<\/a> for particulate matter, including PM2.5 and PM10, which are recognized globally. These WHO guidelines are designed to protect public health and are based on scientific evidence regarding the health effects of exposure to particulate matter. They are intended to help countries set their own air quality standards and regulations that aim to minimize the health risks associated with air pollution.<\/p>\n\n\n\n

Here are the WHO air quality guidelines for PM2.5 and PM10:<\/p>\n\n\n\n

* \u00b5g\/m\u00b3 – micrograms per cubic meter<\/p>\n\n\n\n

What is the PM2.5 Annual Limit?<\/h2>\n\n\n\n

The PM2.5 annual limit is the highest amount of tiny particles (PM2.5) allowed in the air during one year. Countries and regions often have their own air quality standards or adopt guidelines set by international organizations such as the World Health Organization (WHO).<\/p>\n\n\n\n

Australia<\/h2>\n\n\n\n

The air quality standards<\/a> are set by the National Environment Protection (Ambient Air Quality) Measure, which is a legislative instrument developed by the National Environment Protection Council (NEPC) in Australia.<\/p>\n\n\n\n
