Common Air Pollutants Air pollution has been a serious problem for a number of years. The air that people breathe in is made from two main types of gases. These gases are nitrogen and oxygen with traces of other gases a well. Air pollution occurs when... Read More | Share it now!
Surgical face masks work better than cheap face masks as protection against air pollutantsWednesday, August 24, 2016 (Health Day News) – According to a new scientific study, face masks made of inexpensive cloth do very little to protect people from pollutants in the air. Although they may be hoping to prevent themselves from smelling the foul air, this does not suffice as an effective protection against air pollution. Nowadays, it is quite a regular scenario in Asia for people to wear their washable or disposable cloth masks while walking along the street. With the increasing rate of air pollution in Asian nations, these masks are being worn as a barrier against particles in the air that may lead to diseases. Unfortunately, according to studies published in the Exposure Science and Environmental Epidemiology Journal, these masks do little to prevent people from contracting illnesses due to air pollution. In fact, cloth masks bought in stores are made of cheap materials that can barely provide the benefits they are supposed to offer. Researchers at the University of Massachusetts also discovered that these inexpensive store-bought face masks perform poorly as protective devices for pollutants. This was the result of the study conducted by health scientists at the said university located in Amherst. Richard Peltier, co-author of this study on the effectiveness of cheap cloth masks against air pollutants, stated that using such masks may pose public health risks. People assume that they are well protected each time they use the mask. However, in areas where the air pollution level is high, these cloth masks have no purpose at all. The Environmental Health Sciences Assistant Professor at the University of Massachusetts also added that plain face masks have limited benefits for people. When it comes to smaller airborne pollutants, such cloth masks do not offer maximum protection. Unfortunately, many people place so much trust in these masks that they may stand next to a diesel truck and assume they are shielded from toxic chemicals and fumes. SOURCE:...
