TL;DR: Tributyltin and its degradation products were measured in seawater samples in 1986-1987 at different locations of the French Atlantic coast, including marinas and oyster culture areas as discussed by the authors.

TL;DR: The introduction of management measures to mitigate deteriorating coastal water quality and the adverse environmental impacts of aquaculture development has now become a matter of urgency to the region.

TL;DR: On controle les teneurs en mercure, cadmium, plomb, hydrocarbures polycycliques aromatiques, PCB, DDD, DDE and DDT dans les especes MyTilus edulis, Mytilus galloprovincialis and Crassostrea gigas.

TL;DR: The first finds of attached populations of the Japanese brown seaweed Sargassum muticum are reported from Norway, indicating the rapid spread of this invasive species in Europe during the last 15 years is discussed.

TL;DR: In 1988 extremely low horizontal advection primarily favoured an accumulation and high aggregation of detritus, and greatly reduced oxygen concentration in the bottom layer of the entire region, an event not observed to such a degree since 1977.

TL;DR: Tolerance to copper and zinc in the polychaete Nereis diversicolor is inherited, which makes it possible to use the occurrence of metal tolerant individuals to map the ecological impact of contamination by these metals.

TL;DR: Macro- and meiobenthos were sampled from Ria Formosa, Portugal along putative sewage pollution gradients in summer 1987 and winter 1988 as discussed by the authors and assessed using multidimensional scaling ordination, ABC plots, and a variety of univariate indices of community structure.

TL;DR: The level of organochlorine bioaccumulation seen in some of the cetaceans analysed is much higher than found previously; this may have serious health implications for populations of those species around the coasts of NW Europe.

TL;DR: Mud snails were collected along gradients of tributyltin (TBT) pollution in the York River-Sarah Creek region of Chesapeake Bay and evidence was found for the sterilization of I. obsoleta by imposex, but the percentages of females in the samples declined significantly with increasing frequency of imposex.

TL;DR: A summary of recent toxic red tides in the southwestern Pacific region is given, showing that the dinoflagellate Pyrodinium bahamense var.

TL;DR: No consistent differences between the two coral reef communities were found; however, high frequencies of blemishes and abnormalities were found and high levels of organochlorine pesticides and heavy metals were detected in several of the reef coelenterates from both sites.

TL;DR: In this article, the authors evaluated the increase in the load of nutrients carried into the Adriatic by the largest Italian river by using analytical data for orthophosphate phosphorus, nitrates and ammonia collected from 1968-1987 at the closure section of the River Po basin.

TL;DR: A review of the available literature on Hong Kong's marine coastal pollution can be found in this paper, where the authors discuss the development of new cities, Shatin and Tai Po, on the shores of the partially enclosed Tolo Harbour.

TL;DR: For corals exposed to daily run-off from an enriched iron effluent, the response is diminished, suggesting that these animals may have developed a tolerance to the metal.

TL;DR: Samples of blubber from common seals (Phoca vitulina) and grey seals (Halichoerus grypus) found dead on the Farne Islands have been analysed for a range of organochlorine pesticides, individual chlorobiphenyl congeners and total polychlorinated biphenyls (PCB).

TL;DR: The accumulation rate increased exponentially for both organic and total tin with decreasing concentration of tin in the seawater, and bioconcentration factors from 5,000–60,000 are much higher than found in other similar studies performed in laboratory.

TL;DR: The coastal waters of Hong Kong receive the sewage discharges from almost 6 million inhabitants, effluents from industry, and agricultural wastes, and these waters exhibit significantly elevated concentrations of trace metals and organochlorines in certain areas, on both local and regional scales as mentioned in this paper.

TL;DR: In this paper, the formation of large agglomerates (clusters) during the generally recommended drying procedures was explained by the grain size effect on trace metals (cadmium, copper, lead, zinc, and iron).

TL;DR: In this paper, the sensitivity of a sediment monitoring station in this respect is a function of the interactions between the change in the net deposition rate of the contaminant, the accumulation rate of sediment, the thickness and intensity of the mixing zone in the bottom sediment and technical factors such as time between samplings, thickness of analysed samples, and reproduceability of applied chemical methods.

TL;DR: REMOTS® technology is a combination of sediment-profile imagery and computer image analysis that can deduce the dynamics of biological and physical seafloor processes from imaged structures.

TL;DR: A study of 57 salmon farms in Scotland has shown that acute organic enrichment, usually accompanied by sediment outgassing, occurred beneath most cages and development of these conditions is considered likely to result in "self-pollution" of the fish farm as discussed by the authors.

TL;DR: This paper reported the analyses of hydrocarbons in the tissues of reef building corals, reef sediments and seawater samples collected in September 1986 as part of the initial impact assessment of a major oil spill in Panama.

TL;DR: In this paper, the siting of caged fish farming in macro-tidal environments may reduce the environmental impact of the industry on benthic communities at the farm site, however there exists the potential for accumulation of farm wastes in nearby sedimentary sinks.

TL;DR: In this article, box cores collected from the Santa Monica and San Pedro Basins during 1986 and 1987 were analyzed for organic carbon, 210 Pb and more than 20 major and minor elements.

TL;DR: The rapidly increasing population and developing agroindustrial activities in Thailand exert considerable stress on the aquatic environment as mentioned in this paper, causing high BOD5 values and bacterial contamination close to populated areas.
