Oxford Street named one of the most polluted places in the world

Oxford Street is now officially known as the area with the highest known concentration of Nitrogen Dioxide (NO2) in the world. A toxic pollutant that can trigger asthma and heart attacks.

Our country’s showcase shopping area has been named a world leader for diesel pollution due to the shopping strip being permanently congested with taxis and buses, whose diesel engines release large amounts of this gas.

We now know just how bad it is, however, for years’ retail and catering staff, office workers, council and utility workers, shoppers and tourists on this and other busy and polluted roads have been completely unaware of the dangers and risks associated with this invisible killer.

Successive Governments and Mayors have avoided the hard steps to tackle this blight that not only affects Oxford Street, but large swathes of London. Instead, the Government and civil service has downplayed the seriousness of the problem and systematically mislead both its own population and the European Commission. Continue reading

Contaminant Sources – Air Pollutants

Air pollution can be categorised as being either particulate (solids) or molecular (gas). Particles are induced into the human respiratory system through breathing. Gaseous or molecular pollution also enters the body in breathing air, but it is able to penetrate beyond the lungs, into the bloodstream and around the entire body.

Camfil - ContaminantsParticulate and molecular pollutants are both present at airports. The principal source is the combustion of fossil fuels.  Jet and diesel engines both release fine particulates in their exhaust. For jet engines the particulates result from incomplete combustion of kerosene fuel. Combustion efficiency reduces at lower engine power levels which are used during landing, taxiing and idling. Diesel engines release high levels of particulates at all duties.

The particulates result from the combustion of both fuel and engine oil.

Diesel particulates fall into several categories:

  • Dry particles or soot
  • Semi-volatile aerosols that have carbon nuclei with oily hydrocarbons condensed on the surface.
  • Carbon particles with sulphur acid molecules condensed on the surface. The sulphur arises for impurities in the fuel. Continue reading

Camfil Case Study published in Government’s Energy Savings Opportunity Scheme (ESOS) Guide

The Department of Energy & Climate Change (DECC) has published the Government Response to the Energy Savings Opportunity Scheme (ESOS) consultation with guidance for potential scheme participants.  The guide includes a Case Study on the successful implementation of ISO 5001 by Camfil UK.

DECC has published the Government Response to the Energy Savings Opportunity Scheme (ESOS) consultation and laid regulations in Parliament to give legal effect to the scheme, and published guidance for potential scheme participants.

A copy of the Government Response and DECC Guidance can be found at: www.gov.uk/government/consultations/energy-savings-opportunity-scheme.

ESOS is an energy assessment scheme that is mandatory for organisations in the UK that meet the qualification criteria. The Environment Agency is the UK scheme administrator.  Organisations that qualify for ESOS must carry out ESOS assessments every 4 years. These assessments are audits of the energy used by their buildings, industrial processes and transport to identify cost-effective energy saving measures. Continue reading
