    Notes: The paper describes and discusses the effect on the local benthic community of the discharge of a dense, saline, effluent into a nearshore area of the North Sea. The monitoring programme continued through the twenty-year period from 1970 until 1989 and includes effectively five years pre-discharge data. Samples were taken from fixed stations with a grab sampler and the invertebrate fauna were identified, wherever possible, to species. In addition, the particle size distribution of the sediment in each sample was determined. The discharge has had a clear effect on the benthic community.This extensive dataset, with its clear gradient of effect, also offers the opportunity of comparing the effectiveness of species and family level identification when studying the effect of disturbance. In this case the impacted area was as readily identifiable from the family as the species level data.

    Notes: This paper describes an investigation into the use of benthic invertebrates to assess impact and recovery following transient pollution events in watercourses. The study showed that benthic macro-invertebrates can be used to assess pollution impact and recovery in streams, provided that (a) the BMWP score is 40 or more (prior to the incident) and (b) there are adequate reference conditions. Monitoring should cover the whole area impacted by the pollutant to allow for spatial variation in benthic macro-invertebrate communities supported by the watercourse. A decision-making strategy for the use of macro-invertebrates in pollution-incident monitoring is provided.

    Notes: Abstract Tees bay on the north-east coast of England receives the waters from the highly industrialised Tees estuary. Since 1970 there have been considerable reductions in both the industrial and domestic sewage discharges to the estuary. The benthic populations of Tees bay have been routinely monitored since 1971, grabbing surveys have been completed at six areas in the spring, summer and autumn of each year. In 1979 the survey was extended to include stations within the Tees estuary itself. Tees bay appears to have a stable benthic fauna. Though the simple analysis of faunal statistics has demonstrated fluctuations within the benthos, neither this analysis nor classification analysis has indicated that there were any long-term changes in abundance or diversity. Classification analysis has also failed to differentiate between the fauna of the different areas within Tees bay. However, studies of biomass and T. fabula growth rate did indicate a difference between the areas close to the mouth of the Tees and those remote from it. The studies of the Tees estuary benthos indicated an improvement in both the abundance and the diversity of the fauna. However, the monitoring took place over a limited period and further work is necessary to ensure that this improvement does not simply represent natural fluctuations within the estuarine benthic population.
