印刷业工人由于长期接触重金属铅的职业关系,如在工作埸所缺乏防护设备装置以及妥善之卫生制度,经过一定的时间后,常易出现铅中毒的临床体征,从而损害机体健康。虽然目前不少的调查研究资料业已征实,印刷业的铅中毒病例大多在轻度中毒的范围内,但不能设想这些中毒患者在未经采取防治措施后中毒程度和机体的机能改变会就此终止。根据作者以往对中毒原因的调查了解,除了操作环境内铅蒸气、铅尘的呼吸道吸入是导致中毒的主要因素外,个人卫生习惯的不良,铅微粒长期随物吞食引起体内铅蓄积也是不能被忽视的原因。为此在设法控制生产场所的铅烟雾或蒸 Due to long-term occupational exposure to heavy metal lead, such as the lack of protective equipment and equipment and proper hygiene in workplaces, printing workers often experience clinical signs of lead poisoning after a certain period of time, thus impairing their health. Although a lot of survey data have been collected, most cases of lead poisoning in the printing industry are within the scope of mild poisoning. However, it can not be assumed that these poisoning patients will terminate in this period without any control measures and the changes of the body’s function .
