Particulate matter pollution

Why is particulate matter harmful to humans? How does particulate matter get into the air? How to reduce particle pollution? Reducing emissions of inhalable particles improves public health as well as visibility. Particle pollution — also called particulate matter (PM) — is made up of particles (tiny pieces) of solids or liquids that are in the air.

PM stands for particulate matter (also called particle pollution ): the term for a mixture of solid particles and liquid droplets found in the air. Some particles are released directly from a specific source, while others form in chemical reactions in the atmosphere. Particle pollution (also called particulate matter or PM) is the term for a mixture of solid particles and liquid droplets found in the air. Particle Pollution (PM) Particle pollution , also called particulate matter or PM, is a mixture of solids and liquid droplets floating in the air.

There are different standards for PM and PM 2. Limiting PM pollution in the air protects human health and the environment. Particulate Matter (PM) Basics to learn about particle types). Numerous scientific studies have linked particle pollution exposure to a variety of problems, including: premature death in people with heart or lung disease. The biggest health threat from smoke is from fine particles. These microscopic particles can penetrate deep into your lungs.

They can cause a range of health problems , from burning eyes and a runny nose to aggravated chronic heart and lung diseases. Exposure to particle pollution is even linked to premature death. Many of them can harm our health, especially very small particles that can enter deep into the lungs. Once inhale these particles can affect the heart and lungs and cause serious health effects. Particles come in many sizes and shapes and can be made up of hundreds of different chemicals.

Others are so small they can only be detected using an electron microscope. Fine particulate matter (PM) in the ambient air is implicated in a variety of human health issues throughout the globe. These particles vary greatly in size, composition, and origin. However, many studies show that the relationship is deeper and far more complicated than originally thought.

These health effects include cardiovascular and respiratory hospitalizations, and premature death. As a California statewide average,. The primary reason for the rise in particulate pollution , type of air pollution , is because of human activities. Common small particles can include lea dust, dirt, and sand. When these components combine, air pollution forms.

Air quality is determined by studying air pollutants present in air which is called as Air Quality Testing. The EPA characterizes particulate matter into two high-risk parameters, generally associated with the size of the particle. Regulation of fine PM in the atmosphere requires information on the dimension of the problem with respect to variations in concentrations and sources. Air quality in the database is represented by the annual mean concentration of particulate matter ( PMand PM i.e. particles smaller than or micrometers, respectively).

Faced with serious particulate matter pollution , China has taken substantial measures to improve energy efficiency and reduce emissions of air pollutants in the last decade.
