How does the quality of our air impact COVID-19?

Air quality is a topic on everyone’s mind at the moment. The air we breathe is composed of around 78% nitrogen, 21% oxygen and 1% other gases. And whilst airborne pollutants have been found in the atmosphere which are harmful to human health and the environment for some time, the spotlight is currently on the pathogen SARS-CoV-2 and how it interacts with the air all around us.

There were hypotheses in March, when the World Health Organisation declared the coronavirus a pandemic, as to whether the virus was able to be transmitted via airborne particles, as early studies had linked a positive correlation between the virus and air pollution. However, five months later and there doesn’t seem to be a ‘one size fits all’ answer. This is due to the quality of air that the virus is introduced to.

An Introduction to Air Quality

Air quality is one of the most significant health challenges of our time. Repeated exposure to air pollutants is reported as one of the top potential causes of several chronic health problems such as lung cancer, cardiovascular disease, and respiratory infections. According to the World Health Organisation (WHO), in 2016 air pollution was linked to over 4.2 million deaths per year and this figure accounted for 11.6% of all deaths.

Air Quality Monitoring with TSI’s BlueSky: A Case Study from Shawcity

As an in-house project, we recently decided to monitor the air quality inside Shawcity from March using the TSI BlueSky Air Quality Monitor. This was at a time when we had a smaller group of staff working at the office due to COVID-19 restrictions, and would help us identify any issues within the workplace before we had our full contingent of staff return. We didn’t necessarily expect to find anything of major concern as we have a clean, non-industrial workplace in a fairly rural setting. We deployed three BlueSky monitors in our reception area, service area and warehouse.

Mercury Vapour Detection

Mercury, also known as Quicksilver due to its being a liquid at normal temperature and pressure (20°C and 1 bar respectively - NIST), was once heavily used throughout the world. Although it has been replaced in the vast majority of applications due to concerns about its toxicity, including very recently in energy-saving lightbulbs, it can still be found in some industrial processes.
