In short, volatile organic compounds are molecules composed wholly or partly of carbon atoms combined with carbon atoms or other elements. These elements evaporate significantly at room temperature and are mostly insoluble in water. Of course, if you want a proper and thorough scientific explanation of what is VOC, you need a dedicated article, so please check out our article on What is Volatile Organic Compound (VOC)?
Volatile organic compounds are everywhere. Paint, paint strippers, cleaning supplies, insecticides, building materials, photocopiers, copy paper, printers, glue, tape, plaster, wood varnish, nail polish, lipstick, air freshener, permanent marker-you choose ! Most of us don't even notice these daily necessities, they are just plain features in our landscape. But the report shows that all these objects, and many more, hide harmful volatile organic compounds behind their boring appearance.
In most cases, humans ingest VOCs through inhalation or through eye or skin contact. However, like almost all pollutants, volatile organic compounds are the most dangerous when inhaled, because the vaporized compounds can pass through the lung's membrane and enter the bloodstream. Generally speaking, ingestion of volatile organic compounds can cause effects ranging from mild skin irritation and respiratory tract irritation to systemic corruption of the central nervous system and various forms of cancer. If you want to know more about the hazards of volatile organic compounds, here is a longer introduction.
Okay, so VOCs are everywhere, and they are harmful-but what is my level of exposure?
The main occupations frequently exposed to volatile organic compounds include:
Well, the first step in safety protection must be monitoring to ensure that at least exposure is kept as low as possible. Under industrial conditions, the most feasible and widely used method is continuous emission monitoring (CEM), which is a method for detecting the concentration of pollutants in the air. The instrument designed to perform CEM is mainly composed of a sample probe that collects a certain volume of air, an analyzer (whether it uses infrared absorption, chemiluminescence, fluorescence, β-ray absorption, etc.) to determine the relevant concentration and a certain filter system that hinders the threat system. Material. There are many types of such systems, so you are sure to find exactly what you are looking for. For a more complete understanding of continuous emission monitoring, please go to our long discussion on what is continuous emission monitoring.
