TL;DR: This paper is concerned with the application of multi-element investigations to problems of human morbidity and the emphasis in the analysis has been optimised towards precision of assay, rather than accuracy, in order that differences in the abundance of elements in similar matrixes may be favourably compared.

TL;DR: It is shown that fluoride added during processing may contribute toward substantial unexpected ingestion of fluoride in infant nutritional regimens and may be larger than the maximum safe daily intake recommended by some authorities.

TL;DR: A number of organic compounds that have been proved to be responsible for odour problems in effluent water, river water and drinking water, and different types of chlorinated compounds are shown to be of importance in relation to offensive water odour.

TL;DR: Primary consideration has been given to aspects of their production and/ or occurrence, reactivity, disposal, concentration, transfer, longevity, biochemical and toxicological nature of their residues in the various biosphere compartments.

TL;DR: The review describes suitable analytical methods for determining trace quantities of selenium in air, water and biological materials and some specific and established ones are given in detail.

TL;DR: This review has attempted to evaluate but a small number of mutagens and potential Mutagens in terms of their occurrence, use patterns, distributions and impact in the environment.

TL;DR: Organic pollutants in seven industrial wastewaters being discharged into the Calcasieu River in Louisiana were identified by gas chromatography-mass spectrometry and chemical characterization provided information beyond that obtainable from traditional pollution measurements and information especially suitable for pollution legislation enforcement.

TL;DR: Arsenic trioxide concentrations in air have been measured without adequate consideration of the physical properties of arsenic compounds in the ambient condition, and quantitative analyses are meaningless.

TL;DR: The spatial pattern revealed has been tentatively accounted for in terms of a number of environmental factors of which geology was found to be the most important, although landuse, topography and climate also exerted an influence.

TL;DR: Ultraviolet and fluorescence spectra of the extracted oils indicated that polycyclic aromatic hydrocarbons were a minor constituent of the organic extract, while mass spectrometry provided supporting evidence of the presence of some components identified in the chromatograms.

TL;DR: In this paper, the distribution and excretion of mercury in rats after oral intake of dimethyl mercury have been investigated and compared with the results obtained with monomethyl mercury by other authors.

TL;DR: The techniques which have been developed the most and which have demanded the most attention are discussed in this review and the present stage of the art is discussed together with the potential of the methods.

TL;DR: In this article, the influence of orally administered dimethyl mercury on the motor coordination of rats was tested and an ED 50 = 65.9±1.7 mg Hg/kg for standard equilibration test of the motor control has been found.
