Freshwater terrestrial assessment

• establishing a protocol towards monitoring air quality using lichens, Pembrokeshire
  

  Integrated desk and pilot study. Lichen diversity indices were assessed based on widely distributed communities and selected lichen samples analysed for trace metals to detect likely pollutant sources.
  (Texaco Ltd, Elf Oil (UK) Ltd, Gulf Oil Ltd)

• monitoring algal communities following Sea Empress oil spill
  

  The rate of algal colonisation after the oil spill was evaluated to provide an indication of the degree of ecosystem disturbance.
  (Countryside Council for Wales)

• assessment of river eutrophication and water chemistry on the River Ouse, Cambs
  

  Pollution levels and the extent of eutrophication in the Anglian region was evaluated using time series data on diatom communities and water chemistry.
  (Environment Agency)

• Malaysia: Mining impact assessment
  

  Determined chemical species mobilised from sulphide deposits and their biological impact on freshwater systems. Bioindicators were used to evaluate contamination levels.
  (Department for International Development)

• Belize: Environmental impact assessment of mining sites
  

  Assessment of the impact of borehole drilling on rainforest communities and aquatic systems including chemical analysis of groundwater.
  (BPH Minerals)

• preparation of evidence for public enquiry
  

  Survey and assessment of invertebrates on exposed riverine sediments in relation to proposed extension of ball clay working with associated river diversions and mineral waste tipping, Devon.
  (English Nature)

• analysis of macroinvertebrate samples
  

  Processing and species level identification and production of validated taxon lists of RIVPACS kick samples from Thames Region sites of varying water quality.
  (Environmental Agency)

• monitoring impact of dust on Burnham Beeches ecosystem
  

  Base-line monitoring programme to record lichen diversity against which future changes may be assessed arising from possible gravel extraction nearby. Chemical analysis of samples.
  (Corporation of London)

• assessing roof and patio deposits, West London
  

  Survey and chemical analysis of growth of lower plants thought by local residents to be of recent origin due to activities associated with Heathrow Airport.
