Environmental impact
Air pollution from air scrubbers, chimneys, fume cupboards, vehicles and engines are mainly localised but still contribute to the emission of carbon dioxide, sulphur dioxide, other harmful gases and pollutants to the atmosphere. Carbon emissions and the release of greenhouse gases are global concerns affecting climatic change and the ecosystem. Accidental release of toxic chemical fumes is harmful to human health and wildlife.

Spread of airborne Legionella bacteria caused by aerosol spray from cooling towers and water fountains can be harmful to health.

Noise pollution from construction and student activities can be a public nuisance.

Performance Status
Air sampling tests are taken at source emission ports of air scrubbers and chimneys. Selective laboratories with fume cupboards that emit potentially toxic fumes are tested for indoor air quality. Water sampling tests are also carried out on cooling towers and fountains for air-borne Legionella bacteria.

Construction activities which potentially cause air and noise pollution are controlled and monitored through environmental site control measures. Exposure to noise emission from air compressors, plant rooms and engine and machine operation are generally low and minimal. Control measures are in place to ameliorate adverse effects. Baseline for noise level has been established at respective sources.

Objectives & Targets – 2007 to 2010
For laboratories, we will continue to monitor, review and ensure emission levels are within legal parameters and set internal control parameters as necessary. More on EMS & Legal Compliance.

2005 – 2006 Financial Year 1 April 2005 to 31 March 2007
Objectives & Targets Performance & Efforts
Ensure air and noise emission levels are within legal parameters and SP’s own requirements respectively and set baseline for measuring performance. Sampling Test Results have been satisfactory. Laboratory emission levels remain relatively low and there is no need to set baseline. More on EMS & Legal Compliance.
