With reference to the Particulate Matter, consider the following state...
Introduction:
Particulate matter refers to the sum of all solid and liquid particles suspended in the air. These particles can be of various sizes and origins, and many of them are hazardous to human health and the environment. In this context, two statements are given, and we need to determine which of them are correct.
Statement 1: Particulate matter is the sum of all solid and liquid particles suspended in air, many of which are hazardous.
Explanation:
Particulate matter (PM) is composed of a wide range of particles suspended in the air. These particles can vary in size, shape, and chemical composition. They can be emitted directly into the air or formed through complex chemical reactions in the atmosphere.
Particulate matter can originate from various sources, including natural processes (such as dust storms, sea salt spray, and volcanic eruptions) and human activities (such as combustion of fossil fuels, industrial processes, and agricultural practices).
Many particulate matter particles are hazardous because of their size and composition. Fine particles with a diameter of 2.5 micrometers or smaller (PM2.5) can penetrate deep into the respiratory system and even enter the bloodstream, causing adverse health effects. These effects can range from respiratory and cardiovascular diseases to premature death.
Therefore, Statement 1 is correct.
Statement 2: This complex mixture includes both organic and inorganic particles, such as dust, pollen, soot, smoke, and liquid droplets.
Explanation:
Particulate matter is a complex mixture that can include both organic and inorganic particles. Organic particles refer to those derived from living or once-living organisms, while inorganic particles are composed of non-living materials.
Examples of organic particles in particulate matter include pollen, spores, and organic compounds emitted from vegetation and biomass burning. Inorganic particles can include dust, soot (black carbon), metals, sulfates, nitrates, and other chemical compounds.
Particulate matter can also contain liquid droplets, such as those formed through condensation of gases or as a result of chemical reactions in the atmosphere. These liquid droplets can include sulfuric acid, nitric acid, and organic acids.
Therefore, Statement 2 is correct.
Conclusion:
In conclusion, both statements given about particulate matter are correct. Particulate matter is indeed the sum of all solid and liquid particles suspended in the air, many of which are hazardous. This complex mixture includes organic and inorganic particles, such as dust, pollen, soot, smoke, and liquid droplets.

With reference to the Particulate Matter, consider the following state...
Particulate Matter:
- Particulate matter is the sum of all solid and liquid particles suspended in air many of which are hazardous.
- This complex mixture includes both organic and inorganic particles, such as dust, pollen, soot, smoke, and liquid droplets.
- These particles vary greatly in size, composition, and origin.
Hence both statements are correct.
