英国彩色玻璃工人的铅危害很少有研究进行了彩色玻璃工人的铅暴露。最近，兰德里根和他的同事们对美国一家工作室进行了调查，他们得出结论，血铅浓度在职业暴露的可接受范围内。“我们调查了英国最大的四个彩色玻璃车间，发现铅暴露的可能性比以前认识到的要大。所有的工作坊都生产彩色玻璃，并修复教堂和其他历史建筑的窗户;其中两个与大教堂相连。对每名工人进行问卷调查，以确定工作细节（包括使用防护服和口罩）、个人习惯（吸烟和咬指甲）和铅中毒症状。在参加国家质量控制计划的健康和安全执行局职业医学和卫生实验室对静脉血样本进行了铅含量分析。在最大的车间，在一天内进行玻璃安装工作时采集了五个背景和五个个人空气样本，两名男子在拆除历史建筑的彩色玻璃窗时佩戴了个人采样器。共有47名接触过放射性物质的工人（39名男子和8名妇女）参加了该项目，只有一名工人拒绝参加。下表显示了血铅浓度的分布;平均值为14 μ mol/l（30 μ g/ 100 ml）（范围0*5-3 4 μ mol/l; 10-70 μ g/100 ml）。9名工人的浓度为1-9 Hmol/l（40 Htg/100 ml）或更高，其中包括一名育龄妇女，根据英国批准的工作守则2，她不得不暂时停止铅工作;她完全在车间内工作，担任玻璃工。没有铅中毒的症状。未发现平均血铅值与工作类型或持续时间之间的关系。吸烟者的浓度高于非吸烟者，但差异无统计学意义。车间内5名玻璃工人个人空气中铅的平均浓度为0 0 3 mg/m3（范围0- 0 1 ~ 0- 0 5 mg/m3），一般空气中铅的平均浓度均为0 0 1 mg/m3。两名拆窗工人空气中铅浓度范围为0 0 1 ~ 0 0 6 mg/m3。所有这些都远低于空气中0-15 mg/m3 r的现行标准。2从拆除的窗户和车间地板灰尘中取出的水泥散装样品中含有2X20%和0X14%的铅。
Lead hazard in British stained glass workers Few studies have been undertaken into lead exposure among stained glass workers. In a recent survey of a studio in the United States Landrigan and his colleagues concluded that the blood lead concentrations were within acceptable limits for occupational exposure.' We have surveyed four stained glass workshops, the largest in Britain, and found that the potential for lead exposure is greater than previously recognised. All the workshops manufactured stained glass and restored windows in churches and other historical buildings; two were attached to cathedrals. A questionnaire was administered to each worker to ascertain job details (including use of protective clothing and masks), personal habits (smoking and nail biting), and symptoms of lead poisoning. Venous blood samples were analysed for lead at the Health and Safety Executive's occupational medicine and hygiene laboratories, which participate in a national quality control scheme. At the largest workshop five background and five personal air samples were obtained during one day while glazing work was performed, and personal samplers were worn by two men on a day when they removed a stained glass window from a historic building. Altogether 47 exposed workers (39 men and eight women) took part and there was only one refusal. The table shows the distribution of blood lead concentrations; the mean was 14 ,umol/l (30 I.lg/ 100 ml) (range 0*5-3 4 ,umol/l; 10-70 ,ug/100 ml). Nine workers had concentrations of 1-9 Hmol/l (40 Htg/100 ml) or over, including one woman of reproductive age who had to be temporarily suspended from work with lead in accordance with the British approved code of practice2; she worked entirely inside the workshop as a glazier. There were no symptoms of lead toxicity. No relation was found between the mean blood lead values and the type or duration of work performed. Smokers had a higher concentration than non-smokers, but the difference was not statistically significant. The mean concentration of lead in the personal air samples of five glaziers inside the workshop was 0 03 mg/m3 (range 0-01-0-05 mg/m3), and the general atmosphere samples were all 0 01 mg/m3. The range of lead concentrations in air samples for the two men removing windows was 0 01-0 06 mg/m3. All of these were well below the current standard for lead in air of 0-15 mg/M3r.2 Bulk samples of cement from the removed windows and workshop floor dust contained 2X20% and 0X14% …
