Abstract

AIMS

The aim of our study was to investigate indoor air quality (IAQ) by comparing pyrogen concentration and microbiological contamination in offices in public buildings.

METHODS AND RESULTS

Air samples were collected during cold and warm seasons in 39 offices in four European cities. Pyrogens were measured by the in vitro pyrogen test (IPT), moulds and bacteria by classical microbiology. In 92% of the investigated offices, pyrogen and microbial contaminations were below 150 EEU m(-3) and 10(3) CFU m(-3), respectively, whilst in 75%, moulds did not exceed 10(2) CFU m(-3).

CONCLUSIONS

The IPT is a rapid, reliable tool for measuring pyrogens that could be used as an 'early warning' indicator of IAQ.

SIGNIFICANCE AND IMPACT OF THE STUDY

This is the first study on pyrogenic compound detection in offices using IPT, which could serve for developing future indoor air guidelines.

摘要

目的

本研究旨在通过比较公共建筑办公室的热原浓度和微生物污染，来研究室内空气质量（IAQ）。

方法和结果

在四个欧洲城市的 39 间办公室中，于寒冷和温暖季节采集空气样本。采用体外热原试验（IPT）测量热原，采用经典微生物学方法测量霉菌和细菌。在所调查的 92%的办公室中，热原和微生物污染分别低于 150 EEU m(-3)和 10(3) CFU m(-3)，而在 75%的办公室中，霉菌含量未超过 10(2) CFU m(-3)。
