Two broad surveys were conducted in February and June 1985 and repeated in 1986 to obtain information on the distribution, habitats and communities in the Lagos lagoon in relation to environmental factors.

These ranged from fine, medium and coarse sands to admixtures of silt and clay which provided a wide selection of habitats.

The percentage of total organic matter was closely associated with the sediment types and the influence of waste inputs. The distribution of several species was influenced by the salinity regime and nature of bottom deposits. Benthic macro-infauna was dominated by molluscs, which were most common in the shallow shoal sands of the northeastern portions of the study area. Species characteristic of stressed environments, notably <em>Capitella capitata, Nereis</em> sp. and <em>Polydora</em> sp., were more abundant in the polluted western industrialized portions. Several species showed seasonal population fluctuations.

Although dispersal of these muds is well documented in marine environments of moderate to high energy, the fate of drilling muds in shallow, low-energy Arctic environments has received little attention. This study focused on three drilling effluent disposal sites around Stefansson Sound in the Alaskan Beaufort Sea. All sites were in shallow (less than 5 m), low-energy marine environments. Sediment concentrations of six metals often present in drilling effluents (aluminum, arsenic, barium, chromium, lead and zinc) were examined. Metal concentrations obtained from replicate grab samples along 100 m transects were compared with those taken at four shallow-water offshore island control sites, and with data from other studies.</p><p>The results indicate persistence of barium, chromium, lead and zinc at certain stations at all three discharge sites, and elevated concentrations of aluminum at one of the three sites when sampled 2–4 years after the discharges. Metal concentrations, when elevated, were typically highest near the discharge points, continued in the direction of wind-induced longshore transport, and generally diminished with distance from the discharge site. However, distributions displayed some patchiness indicative of in place melting of ice-rafted muds or reworking of sediments by currents or icegouging.</p><p>Further work will be needed to evaluate the biological impacts of drilling effluents. However, the slow dispersal of these materials suggests there is a need for closer evaluation of drilling effluent persistence problems at shallow, lowenergy locations in the Beaufort Sea.</p></div>","PeriodicalId":100982,"journal":{"name":"Oil and Chemical Pollution","volume":"7 3","pages":"Pages 225-247"},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0269-8579(05)80028-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79479547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of various parameters on the absorption of phenols by PUfoam was examined. Maximum absorption can be achieved at a flow rate of I ml/min in the range pH 3–9, which is marginally increased as the temperature of the effluent variesfrom 30 to 60°C. As phenol concentration is increased, though the total quantity of phenol absorbed increases, the percentage absorption decreases. It is also observed that at low concentrations of some phenols, satisfactory extraction can be achieved even with increasing volumes of aqueous phase. Based on the extraction data, an extraction mechanism was proposed. Model schemes for the removal and recovery of phenols from industrial effluents (10–100 kl), both by dynamic and static methods, are proposed.</p></div>","PeriodicalId":100982,"journal":{"name":"Oil and Chemical Pollution","volume":"7 4","pages":"Pages 349-365"},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0269-8579(05)80049-8","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76658814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
