Particulate Matter is Responsible for Causing Lung Diseases in Humans and Animals

Jul 04, 2018

Urban air pollution is raising concern worldwide. People today are more informed about the threats of environmental pollution than they were during the last few decades. A part of this is due to the continuous research and publishing of material in the field. For example, air pollutants, today we all know about the PM particles and their growing pathological role.

In this post we have a look at the evolution and effects of PM particles on human and animal health.

Since the Industrial Revolution began we have been using the natural resources at an increased pace. This in turn has led to polluting of environmental elements. Use of fuels, mining and construction activities and rising electricity demand are the main causes of environmental air pollution. Particulate Matter is released during all these activities.

Particulate Matter

Particulate Matter is solid or liquid suspended in the atmosphere, it is also known as aerosol. Traffic emissions are one of the major reasons behind the release of PM particles in the air. Other main sources include thermal power plants, construction industry, and certain types of industrial activities.

Types of Particulate Matter

Diesel Exhausts Particles (DEP) are produced through engine combustion of diesel-based fuels. DEP may also contain transitional metals such as vanadium and zinc.

Residual Oil Fly Ash (ROFA) is a complex mixture of sulfates, nitrogen compounds, carbon and metals. Utah Valley Urban Air Particles (UAP) was first discovered in America but since then it has become a commonly used term for PM particles with high transitional metal levels.

Size and Effects

Size of Particulate Matter plays an important role in determining their lethality. PM particles of different sizes are present in the atmosphere. The ultra-fine PM-2.5 can penetrate the lungs and begin sedimentation. Moreover, prolonged exposure may lead to the mixing of PM particles in the bloodstream and reaching brain, heart, liver etc.

 Respiratory Effects

 PM particles can lead to local damage in to the lungs by entering the mucous layer. This can further result in damage to the whole respiratory apparatus causing diseases like COPD, asthma and fibrosis.


Asthma is one of the most common respiratory diseases in the world. Some studies have found a correlation between asthmatic symptoms and exposure to UAP.

Chronic Obstructive Pulmonary Disease

Chronic obstructive pulmonary disease (COPD) is characterized by an airflow limitation, an obstruction that is not reversible like in asthma. High air pollution is one of the primary causes of COPD.

Combating Air Pollution

Using smart home devices like air purifiers and air filtration units reduces the exposure to PM particles. These devices us state-of-the-art HEPA filters, which are also used in Nuclear Reactors, to trap even the minutest of dust particles. Furthermore, air purifiers from recognized brands like Livpure also come with an activated carbon filter to remove gaseous and liquid pollutants. Air purifiers can also be used to remove pet dander and pet odor from the ambient environment.

Thus, if you are living in a metro city, it is prudent to invest in a smart home product like an air purifier because till the time we solve the problem of air pollution collectively, these products are our only protection.
