Chemical Pollution

Potential biodiversity issues

  • Damage to habitats by introduction of toxicity into habitats/substrate
  • Mortality of or injury to species (plants, birds, invertebrates, fish)
  • Secondary damage or disturbance to habitats and/or species during “clean up” operations

Potential mitigation measures

  • Assess the sensitivity of the area affected or likely to be affected by the pollution: is it in or in proximity to a statutorily designated site; is it in or in proximity to an area of particular importance (e.g. one likely to hold high concentrations of bird species). See bird density maps and Oil Spill Response GIS
  • Alert Environment Agency and/or Counter Pollution Branch of MFA to biodiversity issues
  • In consultation with EA/CPB, if operationally feasible seek to direct polluting materials away from most sensitive sites (in the estuary in particular those likely to support highest concentrations of bird species – see maps)
  • In consultation as above and if appropriate following advice from Natural England, minimise any physical disturbance or further chemical pollution during remedial actions
  • If mortality or injury of species is likely or confirmed, make best efforts to inform RSPB and RSPCA.
