¶ … Testing and sampling devices for monitoring volatile and semi-volatile organic compounds in indoor air by Zabiegala and Namiesnik (2012). The article begins by noting that indoor air quality is usually worse than outdoor air quality, and that issues with indoor air quality affect humans physiologically in ways that are often detrimental. Chemical compounds are" emitted from building and construction materials, and from indoor equipment." As industrial hygienists know, there are many different devices by which indoor environments can be tested for air quality.
Tests of building materials are done using either mathematical modeling or laboratory experiments using emission test chambers. In the field, however, testing is more complicated. The authors discuss the different types of analytical instruments that are used in the field for emissions testing. These include field and laboratory emission cells (FLECs), which are used to test for contaminants on flat surfaces. There are many types of FLECs on the market. Passive flux samplers works well in the field and the authors outline the different types of these on the market as well.
Another type of testing method is direct thermal desorption, which is used for "dry, homogenous materials" and works by trapping materials and heating...
The authors conclude with a table that compares the different types of tests on the basis of time frame, cost, difficulty, lab space and different usage characteristics. The findings highlight the value of passive flux samplers for the field, as well as FLECs.
It is important that the right testing method be chosen because indoor air quality affects performance in a business. Poor air quality can lead to negative health outcomes, in particular where there are dangerous pathogens in the air. Performance can also be affected, as poor air quality can manifest in workers as drowsiness, which lowers productivity and increases the risk of injury, which lowers productivity further. Because of this importance, it is vital that businesses check their ventilation systems regularly. Improper ventilation is a major contributing factor to poor indoor air quality. Systems typically work on a building-wide level, but regardless having an effective system in place, one that deals with a wide range of pathogens and pollutants, will improve workplace health outcomes and likely will improve profitability as well.
Oddly, there are not always guidelines with respect to pollutants. In some cases, this makes sense, such as with mold spores. There are 100,000 types…

IAQ for Students There are many factors and considerations that can be assessed when it comes to the quality of a student's living environment. Many people point to things like temperature in the classroom, the books being used, the availability of materials, the quality of the teachers, the condition of the schools and so forth. However, one condition that is missed a lot of the time would be the indoor air
Air pollution pertains to substances and gases in the air that threaten health and life. Among these are pollutants and irritants, such as nitrogen oxides, sulfur dioxide, and carbon dioxide; particulates, volatile organic compounds (VOCs), toxic substances and some natural substances, like pollen. But most of the pollution comes from the by-products of industrialization - fossil fuel combustion, transportation, transportation, power plant emissions and those from other industrial processes. The
Industrial Hygiene Indoor air quality testing is necessary to ensure that the air in working environments is free from pollutants, or that if there are pollutants that workers can take the precautions necessary to protect themselves. This paper will examine the air quality readings from the test site, outlining the issues that may be present. The first thing to consider is the role that humidity plays in air quality testing. It has

Air Pollution The air that surrounds us is a mixture of 78% nitrogen; 21% oxygen; less than 1% of carbon dioxide, argon, and other gases; and varying amounts of water vapor. Any other particles, gases or unoriginal constituents hanging in the air which are not part of its original composition are called 'Pollutants' and this kind of air is called Polluted Air. Even inhaling small amounts of such air pollutants can
Communicable Disease: Measles Although measles has been almost completely eradicated from the Americas, dozens of cases still occur each year in the United States due in large part to transmissions of the disease from travelers returning from abroad. Because it is highly contagious, outbreaks of measles must be addressed as quickly as possible. This paper provides a review of the relevant peer-reviewed and scholarly literature to describe a communicable disease
