This study documents an unrecognized source of polychlorinated biphenyls (PCBs) to indoor and outdoor environments from mass-market paperback book adhesives. The PCB content of common consumer products like books is less documented than industrial products. Patents describe PCBs as components for hot-melt adhesives used for “perfect” bound paperback bookbinding. However, the PCB formulations, concentrations, and dates of use for these adhesives have not been confirmed by chemical analysis. We tested production-dated paperback books manufactured between 1946 and 1974 from six major publishers. Chemical analysis of the binding adhesive confirms the widespread presence of PCBs in paperback books. PCBs were detected in adhesives from all tested books manufactured between 1948 and 1974 (n = 21). High PCB concentrations (6.1–18 wt %/wt), consistent with use as a plasticizer, were found in half the samples (n = 12). We tentatively identified polychlorinated terphenyls (PCTs) in four samples with lower, ppm-level PCB concentrations. From 1948 to 1974, we estimate that over 6 billion mass-market paperback books were sold domestically, many of which remain in homes, libraries, and stores. Therefore, book adhesives may be a potential PCB source to indoor air and to the environment via paper mill effluent, landfills, and recycled paper.

开本,开源:大众市场平装书胶粘剂中的PCB使用

这项研究表明,大众市场的平装书胶粘剂无法识别室内和室外环境中的多氯联苯(PCB)来源。与工业产品相比,书籍等普通消费产品的PCB含量记录较少。专利将PCB描述为用于“完美”装订平装本装订的热熔胶的成分。但是,这些粘合剂的PCB配方,浓度和使用日期尚未通过化学分析确定。我们测试了1946年至1974年之间由六家主要出版商生产的生产日期平装书。对粘合剂的化学分析证实了平装书中PCB的广泛存在。在1948年至1974年之间生产的所有经测试的书本的胶粘剂中都检测到了PCB(n= 21)。在一半的样品(n = 12)中发现与用作增塑剂一致的高PCB浓度(6.1–18 wt%/ wt )。我们初步确定了PCB浓度较低,ppm级的四个样品中的多氯联苯(PCT)。从1948年到1974年,我们估计国内销售了60亿本大众市场平装书,其中许多仍然存在于住宅,图书馆和商店中。因此,书胶可能是造纸厂废水,垃圾填埋场和再生纸对室内空气和环境的潜在PCB来源。
