According to current research a significant fraction of coronavirus infections are due to aerosols, small liquid droplets. These microparticles are present in our surroundings when we breathe, laugh, speak and of course cough. Because of their very light weight they can remain suspended in the air for long periods of time and contain potentially infectious viruses. Top-ranking virologists assert that just as many infections are caused by aerosols as by droplet transmission.
The risk of infection from aerosols is especially high wherever many people are in the same room – an estimated eight litres of air per nose per minute is exhaled. Contained in the exhaled air is CO2, carbon dioxide, and wherever a large quantity of exhaled CO2 is present in the air, many aerosols are also present.
Regular intensive ventilation is important and with the W&T climate sensors for VOC and CO2 solutions you can record and monitor indoor air quality and receive alarm messages when the air quality is below a critical value.
What are VOCs and where do they come from?
The English abbreviation “VOC” stands for volatile organic compounds, which are present in the air in gaseous or vapor form at room temperature.
Many solvents, liquid fuels and synthetically manufactured substances may be present as VOCs, but also many organic compounds which are formed in biological processes. Humans and animals give off VOC through breathing or directly from the skin.
