【摘要】：目的分析2008—2012年粵西地區(qū)某市部分企業(yè)工作場所噪聲和粉塵危害情況。方法收集、整理2008—2012年粵西地區(qū)某市299家企業(yè)噪聲和粉塵檢測結(jié)果數(shù)據(jù),采用SPSS 19.0軟件進(jìn)行統(tǒng)計(jì)學(xué)分析。結(jié)果2008—2012年累計(jì)檢測企業(yè)299家,檢測噪聲和粉塵作業(yè)點(diǎn)共1 730個(gè),超標(biāo)點(diǎn)數(shù)742個(gè),超標(biāo)率為42.9%。990個(gè)檢測點(diǎn)噪聲強(qiáng)度為(82.8±7.1)dB(A),超標(biāo)率為36.2%;噪聲超標(biāo)率隨著年份的增加而增加(P0.01),2012年噪聲超標(biāo)率最高,為48.6%;小型企業(yè)噪聲超標(biāo)率高于中型企業(yè)(39.5%vs 18.9%,P0.01);不同行業(yè)噪聲超標(biāo)率差異有統(tǒng)計(jì)學(xué)意義(P0.01),以木制家具制造業(yè)超標(biāo)率最高,為62.3%。740個(gè)檢測點(diǎn)粉塵檢測結(jié)果中位數(shù)為2.0 mg/m3,超標(biāo)率為51.9%;2008年粉塵超標(biāo)率最高,為61.9%;小型企業(yè)粉塵超標(biāo)率高于中型企業(yè)(55.6%vs 13.6%,P0.01);不同行業(yè)粉塵超標(biāo)率差異有統(tǒng)計(jì)學(xué)意義(P0.01),以建材行業(yè)和木制家具制造業(yè)超標(biāo)率較高,分別為58.1%和54.4%。結(jié)論該市建材行業(yè)和木制家具制造業(yè)工作場所噪聲和粉塵危害較嚴(yán)重,應(yīng)加強(qiáng)職業(yè)病防控工作,確保作業(yè)人員健康。
[Abstract]:Objective to analyze the noise and dust hazards in some enterprises in a city in western Guangdong province from 2008 to 2012. Methods the data of noise and dust detection were collected and sorted out from 2008to 2012 in a city in western Guangdong province. The data were analyzed by SPSS 19.0 software. Results there were 1 730 detection noise and dust operation points and 742 points exceeding the standard in 2008.The noise intensity of 990 detection points was 42.9%. The noise intensity of 990 detection points was 36.2% (82.8 鹵7.1) dB (A),). The noise excess rate increased with the increase of the year (P0.01), and the noise excess rate in 2012 was the highest (48.6%), and the noise excess rate in small enterprises was higher than that in medium-sized enterprises (39.5%vs 18.9%, P0.01). There was a significant difference in noise excess rate among different industries (P0.01), the highest rate was 62.3% in wooden furniture manufacturing industry, and the median of dust detection results at 740 detection points was 2.0 mg/m3, exceeding standard rate was 51.9%; In 2008, the rate of dust exceeding standard was the highest (61.9%), and that of small-sized enterprises was higher than that of medium-sized enterprises (55.6%vs 13.6%, P0.01). There was a significant difference in the rate of dust exceeding standard in different industries (P0.01). The rate of exceeding standard in building material industry and wooden furniture manufacturing industry was 58.1% and 54.4% respectively. Conclusion the noise and dust hazards in the workplace of building materials industry and wooden furniture manufacturing industry in this city are serious. It is necessary to strengthen the work of occupational disease prevention and control to ensure the health of workers.
