Showing papers in "Science of The Total Environment in 1972"

TL;DR: Cachexia and depletion of the lymphoid system and liver damage were the most important findings in these animals.

TL;DR: Some problems associated with multi-element analysis of biological materials by spark source mass spectrometry, X-ray fluorescence analysis and radioactivation analysis are discussed and particular attention is paid to the importance of the laboratory environment.

TL;DR: In this article, the effects of reservoir construction on downstream water temperatures were investigated and a case study of the Yorkshire Lune employing field observations collected over a two-year period is described.

TL;DR: In this article, the initial results of a monitoring program with respect to toxic substances in the river Rhine are presented together with experimental details on the analytical methods used, covering the period, September 1969-March 1972.

TL;DR: An ion exchange and extraction chromatographic separation method suitable for the simultaneous determination of up to 40 elements in reactor-irradiated biological material was developed in this paper, which requires a separation time of exactly 5 minutes for up to 3 samples when dissolved.

TL;DR: Pesticide residues in wildlife are important as indications of the potential hazard to wildlife from pesticides, and are also used to survey the degree of environmental contamination, but quantitative statements are fraught with difficulties.

TL;DR: Several analytical methods were employed to determine the concentrations of cholinesterase inhibitors in several Dutch surface waters.

TL;DR: The results imply that phospholipid phosphate and ester groupings, and aromatic substituents in protein are the most likely important binding sites for DDT.

TL;DR: The toxic potential of a limited number of mycotoxins, biologically active natural products and trace elements has been reviewed from a primary focus of selection as to their contamination of the food supply whether by direct consumption or via domestic animals used for milk production or meat consumption.

TL;DR: In this article, the authors found that radish and lettuce plant parts, grown in soil treated at three rates with cadmium chloride in pot tests, depend upon the interaction of these treatments with 5 rates of soil-applied lime.

TL;DR: Results are reported for the concentration of 32 elements present in commercially available concentrates of DNA and RNA in sub-cellular materials and the need to establish base lines for the concentrates is discussed.

TL;DR: Investigations on samples of hair from normal and protein-deficient children in Indonesia are described, hoping some of the changes in metal content might be useful in diagnosing incipient protein deficiency.

TL;DR: It is stressed that not only are chemical pollutants capable of producing any one or more of a variety of acute and chronic toxicities, but they may also interact in vitro and in vivo to produce synergistic or potentiating effects.

TL;DR: A dose dependent increase in rat hepatic microsomal demethylase activities associated with an increase in relative liver weight was found after repeated i.p. injections of piperonyl butoxide, similar to that seen after treatment with DDT.

TL;DR: The correlation coefficient between the corrected estimated maximum daily SO 2 concentration and the true maximum concentration was found to be r = 0.94, showing that the proposed method yields satisfactory estimates of these concentration parameters.

TL;DR: In this paper, it has been shown that the world-wide atmosphere is similar at moderate distances (a few kilometres in the vertical or a few tens of kilometers in the horizontal direction) from particular sources.

TL;DR: An accurate and simple method using atomic absorption spectroscopy has been developed to determine lead concentrations found in commercial gasolines as mentioned in this paper, using 48 gasoline samples collected from the Ottawa area.

TL;DR: Hepatic microsomal drug metabolizing enzymes induced in rats by p, p′-DDT reach peak activity 5 days after injection, and return to control values on the 15–19th day, and reinduction with different characteristics occurred and persisted for 50 days.

TL;DR: A review is made of some of the scientific and administrative procedures which have been suggested as possible methods of eliminating persistent economic poisons, such as DDT, from the environment.
