TL;DR: This review provides a basis for substantiating both kinetically and pathologically the differences between chrysotile and amphibole asbestos, and suggests that the risk of an adverse outcome may be low with even high exposures experienced over a short duration.

TL;DR: The indoor environment can be very polluted with pollution levels indoors higher than those outdoors, particularly so when there are combustion processes associated with cooking heating or smoking, and poor ventilation as discussed by the authors.

TL;DR: In the subjects studied there was no major difference in the rate of elimination although the amount of cinnamic acid converted was less in those with phenylketonuria, which may reflect reduced first-pass absorption by the liver in untreated phenyl ketonuria enabling increased uptake to occur in other parts of the body.

TL;DR: Three grades of ceramic fibre have been examined for their composition, structures and biological effect in several in vitro assay systems and devitrification occurring during the use of these materials in high-temperature environments will not necessarily enhance their adverse biological activities despite the production of one phase of crystalline silica.

TL;DR: It is concluded that a simple quantitative relationship between the labelling of these metabolites and the synthesis of labelled tyrosine from labelled phenylalanine in liver is unlikely.
