Fugitive dust, which primarily contains PM10 particles and subgroup particles PM2.5, imposes several health risks. Basically, PM10 denotes the size of particles which is 10 microns (10^-2 mm) or smaller.

The main source of their emission is vehicular traffic that blows sand deposits nearby roads & highways. The wind created by coming & going of vehicles make these minute dust particles airborne, which then can enter the human respiratory system and cause several diseases including asthma. Other main sources of fugitive dust emission are construction sites.

In the US, there are several strict regulations by Government for fugitive dust control. So apart from avoiding health issues, preventing government’s penalties is another reason to pay heed to dust control.

Traditionally, there are many methods for fugitive dust emission control. Here is a brief descriptive of some popular methods.

Natural Dust Control Methods

These methods chiefly follow the approach ‘prevention is better than cure’. Such methods include plantation & mulching areas with the absence of vehicular traffic or applying gravels etc. in the areas where mulching, planting etc. are not feasible. Other techniques include watering the surface regularly, constructing wind screens to reduce emission, etc.

Chemical Dust Suppression

There are several chemical dust suppressants commercially available today. They provide a comparatively efficient solution to natural methods; however, their performance depends on various factors such as geological conditions, the mechanical stability of surface, etc. Besides, chemical suppressants have many other shortcomings such as, they are corrosive or ignitable. They may also contain toxins, so can also be hazardous to the environment.

Dust Control Polymers

The most recent & most advanced methods for dust control solutions are polymers. Soil Stabilization Innovations is proudly the pioneer of the practice of using polymers for dust control. Our line of acrylic polymers are more effective than chemical suppressants in every sense. They last longer, work with all soil types, are not non-corrosive, do not leach, and most of all – are environment friendly. As a matter of fact, with some soil types our line of polymers even promote the germination.

Commercially & scientifically, using polymers for duct control is the best industry practice. Those who are still practicing natural methods but find them inefficient, or those who are using chemical suppressants, should definitely switch to dust control polymers.
