The aim of this work was to record the quantities and composition of medical waste (MW) generated by public and private medical histopathology laboratories (HISTOLB) and to provide pertinent waste generation design coefficients (e.g. g/examinee) for those laboratories. This can be a useful coefficient when designing medical waste treatment facilities. The study was conducted on three public and four private HISTOLBs in the city of Thessaloniki (Greece) for a period of 5 months. One sampling week was selected randomly per month. During the study period, the examinees per week were 108 and 90 in the public and private HISTOLBs, respectively. According to the results, 57% of the total MW generated in both the public and private laboratories were toxic waste (TXW), namely the liquid formaldehyde that is used to preserve the tissue. The mixed hazardous waste (MHW) comprised 28% and 24%, respectively, of the total MW, in the public and private facilities, respectively. The infectious waste constituted around 15% of the total MW generated in both types of facilities. Urban type waste was always less than 4% by weight. The total mean MW generated in the public and private laboratories were 208 ± 543 (n = 1614) and 195 ± 512 (n = 1789) g/examinee, respectively. A large variance among the mean MW generation rates of the participating individual laboratories that belonged to the same category was observed. The dominant fraction of the infectious waste was the plastic containers that contained the tissue samples, being around 75% of the total infectious waste, followed by the latex gloves (being around 17% of the infectious waste).
本工作旨在记录公共和私营医疗组织病理学实验室（HISTOLB）产生的医疗废物（MW）的数量和组成，并为这些实验室提供相关的废物产生设计系数（例如，每检查者克）。当设计医疗废物处理设施时，这是一个有用的系数。该研究在希腊塞萨洛尼基市的三家公立和四家私立 HISTOLB 进行，为期 5 个月。每月随机选择一个采样周。在研究期间，公立和私立 HISTOLB 每周的检查者分别为 108 人和 90 人。根据结果，公立和私立实验室产生的总 MW 的 57%为毒性废物（TXW），即用于保存组织的液体甲醛。混合危险废物（MHW）分别占公立和私立设施总 MW 的 28%和 24%。公立和私立设施产生的总 MW 中，传染性废物约占 15%。城市类型废物的重量始终小于 4%。公立和私立实验室产生的总平均 MW 分别为 208±543（n=1614）和 195±512（n=1789）克/检查者。属于同一类别的参与个别实验室的平均 MW 生成率存在很大差异。传染性废物的主要部分是含有组织样本的塑料容器，占总传染性废物的约 75%，其次是乳胶手套（占传染性废物的约 17%）。
