Showing papers in "Environmental Pollution in 1979"

TL;DR: The earthworm Lumbricus rubellus takes up and retains lead from soil containing a high concentration of lead, regardless of the copper, zinc and manganese concentrations in the soil, these metals appear to be regulated in the tissues as mentioned in this paper.

TL;DR: In this article, the authors found that lead from automotive sources in roadside soil and vegetation is found to follow a double exponential function of the following form: Pb = A 1 e − k 1 D + A 2 e −k 2 D.

TL;DR: The effect of Louisiana crude oil on the growth of S. alterniflora Loisel and selected anaerobic soil processes in a Louisiana salt marsh was investigated in this article.

TL;DR: The feeding habits and migrations of the great skua make it a suitable indicator of offshore pollution in the north-east Atlantic and Mercury levels in primary feathers correlate with those in liver so may be used to monitor without killing birds.

TL;DR: Arsenic, cadmium, copper and zinc occur at elevated levels in the waters of Carnon River and the upper reaches of Restronguet Creek, these concentrations decreasing progressively towards the estuary of Carrick Roads as discussed by the authors.

TL;DR: Lead poisoning due to the ingestion of lead fishing shot was shown to be the cause of death of a number of mute swans Cygnus olor Gmelin and consistently elevated liver levels of iron and zinc and a marked loss of body weight were all directly proportional to the increase in kidney lead concentration.

TL;DR: The highest concentrations of zinc (7023 ppm/ dry weight) and lead (16,000 ppm/dry weight) were recorded in plants growing nearest the mines, reflecting the extent of metal pollution in the water as discussed by the authors.

TL;DR: In this article, the content of total water extractable SH compounds was estimated in healthy and SO 2 -affected leaves of Picea, Pinus, Larix and Betula.

TL;DR: In this paper, a factorial experiment involving varied levels of soil fertility showed that when the amount of nitrogen available in the soil is low, the plants can tolerate, and even benefit from, nitric oxide in the atmosphere.

TL;DR: A procedure for observing the effects of dissolved copper and other metal ions on the submersed aquatic macrophyte Elodea canadensis has been described in this article, where metal concentrations have been determined which inhibit light-induced oxygen evolution from plant segments after short-term exposure (24h), and which produce phytotoxicity in whole plants over a longer period (28 days).

TL;DR: High lead concentrations in the food of litter-dwelling Collembola appear not to have any harmful effects and the concentration of lead in faeces and in the mid-gut epithelium may be of importance for the food-chain associated with collembolan products.

TL;DR: Exposure to cadmium had no effect on the number of days to onset or frequency of reproduction but it did cause a reduction in the percentage of adults producing young, theNumber of broods per adult, the Number of young per brood, thenumber of progeny per adult and the intrinsic rate of natural increase.

TL;DR: Roe deer antlers from three southern forest regions in Poland exposed to industrial pollution and from Bialowieza Forest were investigated with regard to heavy metal and sulphur content.

TL;DR: In the starling liver there are seasonal variations in the concentrations of zinc, copper, iron, cadmium and mercury, and some of these variations may be related to seasonal changes in the fat and protein content of the liver.

TL;DR: It is concluded that SO 2 and NO 2 in combination may be more toxic to plants than would be predicted by summing their individual effects on growth.

TL;DR: In whole animals, all metals analysed, except magnesium, were higher in concentration at the Cwmystwyth site where high amounts of lead, zinc and manganese but low concentrations of calcium and phosphate were found in vegetation.

TL;DR: The diminution of chlorophyll and protein contents and increased activities of enzymes G6PDH, ICDH, ALT, AST and GlDH have been used as indicators of low pollution levels which do not produce visible damage on plants as mentioned in this paper.

TL;DR: In this article, the concentrations of zinc, cadmium, lead and iron were determined in whole soft parts of mussels, Mytilus edulis (L), and in growing tips of the alga Fucus vesiculosus (L.) from a total of 20 locations in the area of the Sound between Sweden and Denmark.

TL;DR: In this paper, the relative sensitivity of leaf photosynthesis to fumigation with sulphur dioxide (SO 2 ) and ozone (O 3 ) was determined over a range of light intensity and relative humidity for sugar maple Acer saccharum Marsh, black oak Quercus velutina Lamb and white ash Fraxinus americana L.

TL;DR: In this article, leaves from eight soybean cultivars differing in sensitivity to sulphur dioxide injury were treated by introduction of sulphite (dissolved SO2) through the petiole.

TL;DR: Zinc concentration of salmon feeding to satiation once daily and exposed to zinc increased during the first two months of exposure before reaching a maximum, while zinc concentration of Salmon offered sub-excess rations increased linearly during a three-month period.

TL;DR: In this paper, the authors investigated the relationship between the distance of the plants and orchards from the road and the number of arthropods associated with them, and found that arthropod densities varied with the distance to the road.

TL;DR: In this article, the authors describe a study of the reinvasion of one lichen, Lecanora muralis (Schreb.) Rabenh, into the West Yorkshire conurbation.

TL;DR: In this article, a practical method of using morning glory Pharbitis nil var Scarlet O'Hara as an index of photochemical oxidants as well as to find the threshold concentration for injury to the plant was established.

TL;DR: A disused pyrite mine in the Conwy Valley, North Wales, was found to contain copious amounts of "acid streamer" of heterotrophic bacterial origin this paper.

TL;DR: In 1970, vegetation in the vicinity of the ERCO phosphorus reduction plant at Long Harbour, Newfoundland (47°26′N, 53°47′W) began to show symptoms of fume damage, e.g. tip-burn and margin-burn as mentioned in this paper.

TL;DR: L'effet toxique de cet insecticide se manifeste aussi sur la fecondite, sur la fertilite des oeufs et sur le deroulement de l'embryogenese (frequence des embryons doubles and multiples: 11·6% avec 1 ppm, 23·5% awith 2 ppm).

TL;DR: In this article, the effects of 10 pphm SO 2 and 10pphm NO 2, applied both singly and in combination, on whole plant transpiration rates of Phaseolus vulgaris L. were investigated.

TL;DR: In this paper, the structure, strength and chemical composition of egg shells of gannets Sula bassana, shags Phalacrocorax aristotelis and great black-backed gull Larus marinus have been studied in relation to egg residues of DDE.

TL;DR: The extent to which particulates from zinc and lead smelters are serious contaminants of Quercus robur and Pinus silvestris foliage was investigated in this article, where chloroform and ultrasonic vibration was used to remove wax and particulate from the foliage surface.
