  author={S{\"o}ren Jensen and Alf G. Johnels and Mats T. Olsson and G. Otterlind},
Analyses of pesticide residues in a wide range of marine organisms from the coastal waters of Sweden show that there is a marked contamination in the Baltic. There are signs of an increase in polychlorinated biphenyls (PCB) from north to south in this area. Exceptionally large amounts of residues were found in white tailed eagles from the archipelago of Stockholm. 
Levels of PCBs and DDTs in mussels from the N.W. Mediterranean
Abstract The concentration of synthetic chlorinated hydrocarbons has been monitored in mussels collected on the north-west Mediterranean coast. DDT and PCB contamination is widespread in this region
Organochlorine Pesticide Residues in Harbour Porpoises from the Bay of Fundy Region
P pesticide residues occur in many forms of life in the marine ecosystem and are concentrated through progressive trophic levels until relatively high levels accumulate in lipid-rich tissues of predatory seals, toothed whales and sea birds.
Chlorinated hydrocarbons in fish-eating birds from the Gdańsk Bay, Baltic sea
Concentrations of HCB, DDT and PCB in tissues of the fish-eating birds staying at their winter quarters in the South Baltic are revealed.
Organochlorines in British grey seals
Abstract Further samples of the organochlorine content in tissues of grey seals from places around the British coast, show high levels of PCBs compared with DDT and dieldrin. Greater concentrations
DDT and PCB in south Swedish streams
Gammarus pulex (Amphipoda) was used as an indicator organism in a regional study of the distribution of chlorinated hydrocarbon residues in different streams in southernmost Sweden, suggesting that transport routes and accumulation processes are much more complicated and inter-specifically variable phenomena than often assumed.
Industrial and agricultural pollution: a threat to the health of children living in the Arctic region
Various environmental pollutants of industrial or agricultural origin such as persistent organic pollutants (POCs) are causing great concern owing to their toxicity to humans and animals. At the
Organochlorine compounds in mussels from Scottish coastal waters
Abstract The extent of pollution of Scottish coastal waters by pesticides and PCBs was assessed using Mytilus edulis as a biological indicator. The prepared samples were examined by GC-ECD (gas
Persistent Organochlorines in Marine Mammals
Various immunological, reproductive and teratogenic dysfunctions have been noted in biota, such as the double crested cormorant and Caspian tern in the Great Lakes region of North America, and the beluga whale from the St Lawrence estuary, generally believed to result from exposure to persistent organochlorines such as polychlorinated biphenyls, poly chlorinated dibenzo-p-dioxins and their related compounds.
Polychlorinated biphenyls in North Atlantic seabirds
Abstract Polychlorinated biphenyls are usually thought to be discharged in industrial effluents and therefore to be commonest in inshore waters close to centres of industry. It now appears that high
Assessment of Environmental Pollutants in Humans from Four Continents : Exposure levels in Slovakia, Guinea-Bissau, Nicaragua and Bangladesh
Humans are continuously exposed to complex mixtures of anthropogenic chemicals. This thesis focus on human exposure to persistent organic pollutants (POPs). POPs ability to bioaccumulate and biomag


Organochlorine Residues in Marine Organisms
The residues of dieldrin in livers and eggs of adult birds are independent of the age of the bird, and marine animals do not appear to be better indicators of environmental contamination by insecticides.
Chlorinated Hydrocarbons in British Wildlife
Polychlorobiphenyl compounds have been detected in British wildlife. In birds' livers and eggs they are often in greater quantities than organochlorine pesticide residues. Polychlorobiphenyls are
Organochlorine Pesticides in Seals and Porpoises
Seals and porpoises in Scotland and Canada, far from the sites of application of pesticides, can accumulate high concentrations of residues in their blubber which cannot be confined to their place of discharge.
Organochlorine insecticide residues in wild birds in Britain.
Organochlorine insecticide residues in a wide range of wild birds and their eggs from all over Britain have been determined by gas-liquid chromatography and paper chromatography. Higher residues were
Polychlorinated Biphenyls in the Global Ecosystem
Polychlorinated biphenyls are widely dispersed in the global ecosystem, and are powerful inducers of hepatic enzymes which degrade oestradiol, which could account for a large part of the aberration in calcium metabolism which has been observed in many species of birds since the Second World War.
Uptake of pp′-DDT and its Post-mortem Breakdown in the Avian Liver
To determine the possible effect of the concentration of residues in various organs on the survival and reproduction of birds, toxicological studies are being carried out by feeding pp′-DDT to Bengalese finches to determine the sub-lethal and lethal ranges of chronic dose rates.
Organochlorine Insecticide Residues in the Eggs of Sea Birds
To explain the anti-tumour effect of RNA it is not necessary to suggest that changes it induces are preserved for a long time, but a decrease over a short period in the ability of implanted cells to autonomous growth simil:ir to short-time changes induced in bacteria by specific RNA from the outside is sufficient for protective mechanisms of the animal to perform their function.
Mercury content in feathers of Swedish birds from the past 100 years
The appearance of increased mercury accumulations in birds mainly in the beginning of the 1940's indicates that alkyl-Hg compounds used as seed dressings are chiefly responsible for that increase.
Ecology and the industrial society
A review is presented of a book which contains material presented at a symposium entitled Ecology and the Industrial Society. The symposium was held April 13-16, 1964 at the University College of
Abstract An evaluation of toxicity by injection of the chemical into the yolk sac of fertile eggs prior to incubation gave the following results: Water, propylene glycol, corn oil, peanut oil,
