A study was conducted to determine the effects of strapped spectacles on the fit factors obtained during quantitative fit testing on three different brands of full facepiece negative pressure respirators. The three brands of respirators wer...
Influence of characteristics of inhaled fibres on development of tumours in the rat lung [0.03%]
吸入纤维特性对大鼠肺肿瘤发生的影响
B G Miller,A D Jones,A Searl et al.
B G Miller et al.
The objective was to examine and quantify the influence of fibre dimensions, persistence in the lung, and dissolution and cell toxicity in vitro, on the risks of developing lung tumours in rats. Data were brought together from the studies c...
Influence of fibre length, dissolution and biopersistence on the production of mesothelioma in the rat peritoneal cavity [0.03%]
纤维长度、溶解性和生物持久性对大鼠腹膜腔间皮瘤生成的影响
B G Miller,A Searl,J M Davis et al.
B G Miller et al.
A range of respirable man-made mineral fibres were tested for evidence of carcinogenicity by injection into the peritoneal cavity of male SPF Wistar rats; and differences in carcinogenicity were related to the dimensions and biopersistence ...
Biopersistence and durability of nine mineral fibre types in rat lungs over 12 months [0.03%]
九种矿物纤维类型在大鼠肺部的生物持久性和耐久性为期一年的研究
A Searl,D Buchanan,R T Cullen et al.
A Searl et al.
The study objectives were to assess the ability of intratracheal injection methods to discriminate between nine fibre types in respect of pulmonary biopersistence, and to provide approximate estimates of relative biopersistence and durabili...
