珍珠岩吸音板不含有石棉不会对人体环境造成健康威胁
 珍珠岩吸音板不含有石棉 For a number of years the health effects of asbestos have been well known. 若干年来对健康的影响，石棉已众所周知。 Because of 由于 the seriousness of the issue and because asbestos is a naturally occurring mineral, 这个问题的严重性，因为石棉是一种天然存在的矿物， concerns have often been expressed as to whether asbestos may be, or is, a contaminant 关注往往对是否石棉可能会，或是一种污染物 in other mineral products. 在其他矿物产品。 From time to time the Perlite Institute has been asked whether perlite contains asbestos 不时珍珠岩吸音板研究所一直在问，是否含有石棉珍珠岩吸音板 contamination or whether perlite is free from asbestos. 珍珠岩吸音板污染或者是否是免费的石棉。 Most typically, these questions are 典型的是，这些问题的 asked of individual suppliers, who in turn must test their product(s) for possible 要求个别供应商，谁也必须检验他们的产品（县）的可能 contamination and provide the results to the inquirer. 污染和提供的调查结果。 Because of this, the Perlite Institute 正因为如此，珍珠岩吸音板研究所 has had very little actual data on the subject. 已经很少实际数据关于这个问题的。 In order to provide this information, both to 为了提供这方面的资料，以 its member companies, to users of perlite products, and, most importantly, to the general 其成员公司，向用户珍珠岩吸音板产品，以及重要的是，向大会 public, the Institute has undertaken a project to collect available data both on perlite ore 公众，研究所开展了一个项目，收集现有的数据都珍珠岩吸音板矿 and expanded perlite products. 和膨胀珍珠岩吸音板产品。 This report summarizes the results of the findings. 本报告总结的结果，调查结果。 The 那个 data is based upon perlite products mined and processed at various locations throughout 数据是根据珍珠岩吸音板产品的开采和加工在全国各地 the World. 世界。 To date, there is no evidence that perlite contains asbestos either from contamination or 迄今为止，没有任何证据表明，珍珠岩吸音板含有石棉无论从污染或 as a secondary component. 作为次要的组成部分。 The following test results have been compiled from tests 下面的测试结果已汇编从试验 conducted by individual member companies: 进行个别会员公司： Sample No. 样品编号 Perlite Type 珍珠岩吸音板型 Detection Limit Asbestos Type(s) 检出限石棉类别（县） Methodology 方法论 ** ** 1 1 ore 铁矿石 <0.0001 % “ 0.0001 ％ ND 北达科他 * * EPA 600/R-93/116 环保局600/R-93/116 2 2 ore 铁矿石 1 % 1 ％ ND 北达科他 XRD X射线衍射 3 3 ore 铁矿石 1 % 1 ％ ND 北达科他 PLM 产品生命周期管理 4 4 ore 铁矿石 any fiber 任何纤维 ND 北达科他 SEM 扫描电镜 5 5 ore (coarse) 铁矿石（粗） any fiber 任何纤维 ND 北达科他 SEM 扫描电镜 6 6 ore (fine) 铁矿石（罚款） any fiber 任何纤维 ND 北达科他 SEM 扫描电镜 7 7 ore 铁矿石 any fiber 任何纤维 ND 北达科他 SEM 扫描电镜 8 8 ore (coarse) 铁矿石（粗） any fiber 任何纤维 ND 北达科他 SEM 扫描电镜 9 9 ore (fine) 铁矿石（罚款） any fiber 任何纤维 ND 北达科他 SEM 扫描电镜 10 10 concrete aggregate 混凝土骨料 - - ND 北达科他 XRD & TEM X射线衍射和透射电子显微镜 11 11 cryogenic 低温 - - ND 北达科他 XRD & TEM X射线衍射和透射电子显微镜 12 12 filteraid filteraid 1 % 1 ％ ND 北达科他 XRD X射线衍射 13 13 horticultural 园艺 1 % 1 ％ ND 北达科他 XRD X射线衍射 14 14 masonry fill 砌体填充 1 % 1 ％ ND 北达科他 XRD X射线衍射 15 15 micro balloons 微型气球 1 % 1 ％ ND 北达科他 XRD X射线衍射 * * ND = none detected 北达科他=无检测 ** ** EPA = EPA test method; XRD = x-ray diffraction; PLM = polarized light microscopy; 环保局=环保局测试方法; X射线衍射= X -射线衍射;的PLM =偏光显微镜; TEM = transmission electron microscopy; SEM = scanning electron microscope 透射电镜=透射电子显微镜，扫描电镜=扫描电子显微镜 These results are reassuring and confirm what has been previously accepted based upon 这些结果令人放心，并确认已根据先前接受 the different geologic origins of perlite and asbestos (ie, perlite is a form of rhyolite 不同的地质根源珍珠岩吸音板和石棉（即珍珠岩吸音板是一种形式的流纹岩 characterized by a fine microscopic and amorphous structure; ie a volcanic glass 其特点是罚款镜和非晶结构;即火山玻璃 whereas asbestos is a mineral and exists as a fibrous form of amphibole. 而石棉是一种矿物和存在形式的纤维状角闪石。 The two are 这两个方面 rarely, if ever, seen in the same deposit.). 很少，如果有的话，看到在相同的存款。 ） 。 The Perlite Institute will continue to monitor 研究所的珍珠岩吸音板将继续监测 this issue and as future tests become available, the results will be made available to the 这个问题，并为未来的测试到位，其结果将提供给 public. 市民。
