Particulate Matter (PM) refers to a complex mixture of tiny particles and droplets in the air, which can adversely affect human health and the environment. PM is categorized by particle size, with PM10 and PM2.5 being common indicators of air quality, as they can penetrate the respiratory system causing various health issues.

Particulate Matter (PM)

Particulate matter (PM) consists of tiny particles or droplets in the air that are harmful to human health and the environment, originating from sources like vehicle emissions, industrial processes, and natural events. These particles can penetrate deep into the lungs and even enter the bloodstream, leading to respiratory and cardiovascular issues, and are a major component of air pollution monitored by environmental agencies worldwide.

Particle size is a critical parameter that influences the physical and chemical properties of materials, affecting their behavior in processes such as dissolution, sedimentation, and filtration. It is essential in fields like pharmaceuticals, materials science, and environmental engineering, where precise control over particle size distribution can impact product efficacy, stability, and environmental impact.

Air quality refers to the condition of the air within our surroundings, which affects human health and the environment. It is determined by the presence and concentration of pollutants and is influenced by natural and anthropogenic sources, weather conditions, and geographic factors.

Air Quality

The respiratory system is a complex network of organs and tissues that facilitate the exchange of oxygen and carbon dioxide between the body and the environment, essential for cellular respiration and energy production. It includes the airways, lungs, and respiratory muscles, working together to ensure proper oxygenation of blood and removal of metabolic waste gases.
