London exceeds 2017 air pollution limit in 5 days

Last week, London breached its annual air pollution limit within just five days, as hourly levels of toxic nitrogen dioxide exceeded 200 micrograms per cubic metre more than 18 times on Brixton Road in Lambeth.

The annual limit was broken just 120 hours into the New Year, highlighting the severity of the capital’s air pollution problem which stems largely from diesel-powered vehicles.

Simon Birkett, director of Clean Air in London, called for a ban on alfresco dining during peak pollution times and claimed that “emergency measures are needed.”

Worryingly for building owners and managers, the effect of outdoor air pollution can also have a significant impact on indoor air quality, as incidents such as these make a mockery of the state of so-called ‘fresh’ air introduced via windows and other ventilation.

Even mechanical ventilation such as heating, ventilation and air-conditioning (HVAC) systems cannot always prevent outdoor pollutants such as volatile organic compounds (VOCs) from entering occupied spaces. So how can building occupants be protected from health problems such as asthma, and other respiratory conditions, not to mention a drop in productivity and rising absence rates?

Gibbons Ultraviolet Solutions provides ultraviolet germicidal irradiation (UVGI) systems for the disinfection of air and surfaces in occupied spaces such as offices, schools, restaurants and healthcare facilities.

One such solution is CoilCare®, a permanent, low-maintenance unit which is mounted within the air handling unit (AHU) of a HVAC system and applies ultraviolet-C (UVC) light to the cooling coil. This destroys contaminants and allows clean air to circulate through the system.

Each CoilCare® installation is designed to order to fit any AHU and its continued use can prevent the re-growth of contaminants.

Find out more about CoilCare® by calling Head of Gibbons Ultraviolet Solutions Colin Hardman on 07940 544206 or email colin@gibbonsgroup.co.uk
