Air Sample Analysis- Air Quality Monitoring
The monitoring of pollutants in the ambient environment can be undertaken by continuous automated analysers, or by means of passive samplers. The passive sampler is the simplest, most reliable and cost effective system for monitoring several pollutants over long sampling periods.
The passive sampler does not require electric power or a sample pump. A collection media adsorbs gas molecules over long periods, typically 3 months in urban areas. Following exposure, the sampler is returned to the laboratory for analysis.
Passive samplers are simple to deploy and operate, and are extremely effective for a range of major pollutants.
MSS specialises in the analysis of passive sample tubes. Airborne pollutants that can be monitored using this technique include nitrogen oxides, sulphur dioxide, ozone, ammonia, benzene, toluene, ethyl benzene and xylene.
Contaminated Land
Contaminated land is a potentially valuable resource for new development, but the extent and degree of contamination must be evaluated before site is reused. The Pollution Prevention and Control Regulations (England & Wales) 2000 requires testing to establish the concentration of particular contaminants in soil. The Environment Agency of England and Wales is proposing to extend its Monitoring Certification Scheme (MCERTS) to the chemical testing of soils.
MSS has expertise and experience in the analysis of contaminated land samples to support the activities of developers and regulators involved in the redevelopment of contaminated sites.
MSS recognises the need for rapid on-site attendance and reporting of results when assessing soil and groundwater contamination. We can provide experienced site chemists, often same-day service and fast-track analysis.
In addition the following services are available for clients engaged in the development of contaminated sites:
- Personal monitoring for dust, gases and vapours
- Environmental boundary fence monitoring for most pollutants
- Noise and vibration testing
