1 The strengths decrease in order crocidolite chrysotile, amosite.

2 The residual substances of crocidolite are mainly silicon.

3 The results showed that Chinese crocidolite asbestos was able to induce lung fibrosis in rats.

4 A method of identification for low content chrysotile, crocidolite and amosite in brake rubber of bicycle by the united way of polarized light microscope and X-ray diffraction had been established.

5 The three most important varieties are chrysotile, crocidolite and amosite.

6 There is at present uncertainty regarding the hazard to health presented by crocidolite.

7 Objective To further examine and study the pathogenic change of crocidolite dust, the fiber self-imperceptible changes, remained features and the new surface morphology of crocidolite surface in rat.

8 The principal forms of asbestos are chrysotile (white asbestos) and crocidolite (blue asbestos).

9 Dissolved and combined with biological acting in rat, the thermal stability temperature of crocidolite becomes quite lower.

10 A total of 7 lung tumours occurred, 3 of which were found in chrysotile group, 2 in crocidolite group, 1 in tremolite and 1 in actinolite group.

11 The Air Pollution Control Ordinance bans the import and sale of the more potentially dangerous types of asbestos, namely amosite and crocidolite , from May 1996.

12 Objective To explore the risk of developing malignant neoplasm in a cohort with the history of environmental exposure to crocidolite asbestos.

13 In the course of the interaction between organism protein and crocidolite, the protein symmetry decreases and the structure loosens.

14 The experiment was designed to examine the fibrogenic action of Chinese crocidolite and chrysotile asbestos by intratracheal injection into rats.

15 Objective To explore the mechanism of cell proliferation cycle change of human embryonic pulmonary fibroblasts(HEPF)induced by crocidolite.
