【摘要】：通過對比分析我國個體采樣方法與美國個體采樣方法對粉塵檢測結(jié)果的影響,找出中美對于粉塵個體采樣不同方法之間的區(qū)別及聯(lián)系。本研究對北京市豐臺區(qū)4個電焊車間的勞動者分別按照中國《工作場所空氣中有害物質(zhì)監(jiān)測的采樣規(guī)范》(GBZ159-2004)和美國《Occupational Exposure Sampling Strategy Manual》規(guī)定的采樣對象選取原則和采樣方法進(jìn)行個體采樣,其中,在中國采樣對象確定原則中,將"不能確定接觸有害物質(zhì)濃度最高和接觸時間最長的勞動者時"的采樣方案定義為第一種方案,將"能夠確定接觸有害物質(zhì)濃度最高和接觸時間最長的勞動者時"的采樣方案定義為第二種方案;美國采樣對象選取的原則按照"最高風(fēng)險概率等于10%,置信區(qū)間為95%時確定采樣對象人數(shù)。數(shù)據(jù)的分析及處理采用統(tǒng)計學(xué)SPSS 16.0軟件進(jìn)行,定量資料的分析采用雙側(cè)t檢驗,定性資料分析采用雙側(cè)χ2檢驗,P0.05為差異有統(tǒng)計學(xué)意義。結(jié)果顯示,采用中國第一方案采樣的檢測結(jié)果均值范圍(1.85±1.46)mg/m3~(5.72±3.81)mg/m3,采用美國方案為(1.85±1.46)mg/m3~(5.44±3.12)mg/m3,中國第一方案的結(jié)果略高于美國方案,差異無統(tǒng)計學(xué)意義;采用中國第二種采樣方案檢測結(jié)果中,某消毒設(shè)備廠、某汽車公司的檢測結(jié)果 (6.34±1.33)mg/m3和(7.42±2.40)mg/m3,略高于美國方案檢測結(jié)果 (3.80±2.01)mg/m3和(3.84±2.67)mg/m3,某車輛裝備公司和某構(gòu)件廠的結(jié)果 (5.41±5.23)mg/m3和(1.00±0.25)mg/m3,略低于美國檢測結(jié)果(5.44±3.12)mg/m3和(1.85±1.46)mg/m3,差異無統(tǒng)計學(xué)意義。在95%可信區(qū)間上限值比較中,中國采樣結(jié)果均較美國采樣結(jié)果有增高的趨勢。在采樣對象較少的情況下,中國個體采樣方法與美國個體采樣方法所得出結(jié)果差異無統(tǒng)計學(xué)意義,但中國個體采樣數(shù)據(jù)及95%可信上限值普遍高于美國個體采樣數(shù)據(jù)。與美國采樣方法比較,我國現(xiàn)行采樣規(guī)范有一些不足,應(yīng)加快我國"采樣規(guī)范"修訂的步伐,滿足職業(yè)衛(wèi)生工作發(fā)展的需要。
[Abstract]:The influence of individual sampling method in China and American individual sampling method on dust detection results was analyzed. To find out the difference and relation between Chinese and American methods of individual dust sampling. In this study, workers in four welding workshops in Fengtai District, Beijing, were sampled according to the Chinese Standard for Monitoring harmful substances in the Air in the Workplace. > (. GB 159-2004). And the United States < Occupational Exposure Sampling Strategy. Manual > the sampling object selection principle and sampling method for individual sampling. Among them, in the principle of sampling object determination in China, the sampling scheme "the highest concentration of exposure to harmful substances and the longest exposure to the laborer" is defined as the first scheme. (B) to define the sampling programme "when workers are able to determine the highest concentrations and longest exposure to hazardous substances" as the second option; The principle of sample selection in the United States is "maximum risk probability is equal to 10%." The sample size was determined when the confidence interval was 95. The data were analyzed and processed by statistical SPSS 16.0 software, and the quantitative data were analyzed by bilateral t test. Qualitative data analysis using bilateral 蠂 2 test (P0.05) was statistically significant. The results showed that. The mean range of the sampling results using the first Chinese scheme is 1.85 鹵1.46 mg / m ~ 3, 5.72 鹵3.81 m ~ 3 路m ~ (3) 路m ~ (3) 路m ~ (3) ~ (-1) ~ (-1). The result of the first scheme in China was slightly higher than that in the United States (5.44 鹵3.12) mg / m ~ (3). The difference was not statistically significant. In the test results of the second sampling scheme in China, the test results of a disinfection equipment factory and an automobile company were 6.34 鹵1.33 mg / m ~ 3 and 7.42 鹵2.40 mg / m ~ 3 respectively. It was a little higher than that of the United States (3.80 鹵2.01g / m ~ 3) and 3.84 鹵2.67g / m ~ (3). The results of a vehicle equipment company and a component factory are 5.41 鹵5.23 mg / m ~ 3 and 1.00 鹵0.25 mg / m ~ 3 respectively. It was slightly lower than that in the United States (5.44 鹵3.12 mg / m ~ 3) and 1.85 鹵1.46 mg / m ~ (3) respectively. There was no significant difference in the upper limit of the 95% confidence interval. The sampling results in China are higher than those in the United States, but there is no significant difference between the Chinese individual sampling method and the American individual sampling method in the case of fewer sampling objects. However, the Chinese individual sampling data and the 95% credible upper limit value are generally higher than the American individual sampling data. Compared with the American sampling method, the current sampling standards of our country have some shortcomings. In order to meet the needs of the development of occupational health work, we should speed up the revision of sampling norms in China.
