摘要

摘要:本研究的目的是评估一种流行的生物指示剂-白蜡苔藓作为生活小区空气污染的生物传感器的可能性,该生物传感器的分析物来自烟草烟雾。采用环境研究中常用的主动生物监测方法——苔藓袋法;该方法的基础是将在清洁地区收集的苔藓暴露在受重金属等污染的地点。然而,这个实验涉及在生活区暴露苔藓,每天大约抽10支烟(第一间房间-厨房)。为了比较,苔藓样本也被放置在另一个可能没有被污染的房间(卧室)。暴露3个月后,采用原子吸收光谱法测定苔藓中的重金属:Mn、Fe、Ni、Cu、Zn、Cd、Pb和Hg。此外,这些分析也在室内吸烟者和其他吸烟者的头发样本中进行了测定;测定的金属浓度与使用非吸烟者头发样本进行的研究结果进行了比较。根据已开展的研究证实,除其他外,暴露在生活区的苔藓会积聚来自烟草烟雾的重金属,如Ni、Zn、Pb和Hg。与不吸烟者的头发样本相比,吸烟者头发样本中的重金属浓度更高。

Mosses as Biomonitor of Air Pollution with Analytes Originating from Tobacco Smoke
Abstract The aim of the carried out research was the assessment of the possibility to use a popular bioindicator - Pleurozium schreberi mosses as a biosensor of the air pollution in living quarters with the analytes originating from tobacco smoke. The moss bag method of active biomonitoring, popular in environmental studies, was applied; the method is based on exposing mosses collected in clean areas in the locations polluted with, for example, heavy metals. However, this experiment involved exposing mosses in living quarters, in which approximately 10 cigarettes were smoked daily (first room - kitchen). For the purpose of comparison, moss samples were also placed in another room (bedroom), which was potentially not polluted. After three months of exposure, the following heavy metals were determined in mosses: Mn, Fe, Ni, Cu, Zn, Cd, Pb and Hg, using the atomic absorption spectrometry method. Additionally, these analytes were also determined in hair samples from the persons smoking in the room and from other smokers; the determined metal concentrations were compared with the results of the studies carried out using hair samples collected from non-smokers. On the basis of carried out research it was confirmed that, among others, the mosses exposed in living quarters accumulate heavy metals, such as Ni, Zn, Pb and Hg, which originate from tobacco smoke. Higher heavy metal concentrations were determined in hair samples from smokers, compared to hair samples from non-smokers.
