我们知道,接触大量的石棉粉尘可引起石棉肺、肺和胸膜的恶性肿瘤、喉和胃肠道癌。多年来认为由铁蛋白包裹石棉纤维形成石棉小体是接触石棉的标志,主要见于从事石棉操作的工人。Thomson 报告在大部份城市居民肺中能够找到石棉小体,提出了无明显职业接触的人也有可能吸入石棉,此意见由于在城市空气和供水中发现石棉纤维而得到证实。 We know that exposure to large quantities of asbestos dust can cause asbestos lung, lung and pleural malignancies, laryngeal and gastrointestinal cancers. For many years, the formation of asbestos bodies from ferritin-covered asbestos fibers is a sign of asbestos exposure, which is mainly seen in workers engaged in asbestos operations. Thomson reported that asbestos bodies can be found in the lungs of most urban residents, suggesting that people with no apparent occupational exposure may also inhale asbestos, as evidenced by the discovery of asbestos fibers in urban air and water supplies.
