摘要：

Inhalation of quartz and cristobalite dusts is commonly linked with health effects although the mechanisms involved are poorly understood. Grinding of these piezoelectric silica polymorphs produces particulates with transient piezoelectric charges. This is likely to cause vigorous reaction with atmospheric gases and, through interaction with surface charges and 'dangling bonds', may lead to the formation of highly deleterious ozonide, superoxide and hydroxyl radicals. It is hoped that this study will encourage experimental work to quantify piezoelectric effects in silica dusts and to develop a method for their neutralisation during cutting and grinding processes.
