“…In a study conducted at two different schools in Osijek, Croatia the levels of benzene in the indoor air were found as 0.44 μg/m 3 and 1.63 μg/m 3 , whereas the ambient benzene level was 0.65 μg/m 3 in both the cases. The higher concentration in the second school was attributed to the new floor lamination and the position of the windows, which were near to possible benzene sources (Brdarić et al., 2019).…”

Benzene is a proven carcinogen. Its synergistic action with other pollutants can damage different components of the biosphere. Literature comparing the air quality standards of benzene, its monitoring methods and global concentrations are sparse. This study compiles the worldwide available air quality standards for benzene and highlights the importance of strict and uniform standards all over the world. It was found that out of the 193 United Nation member states, only 53 countries, including the European Union member states, have ambient air quality standard for benzene. Even where standards were available, in most cases, they were not protective of public health. An extensive literature review was conducted to compile the available monitoring and analysis methods for benzene, and found that the most preferred method, i.e, analyzing by Gas Chromatography and Mass spectroscopy is not cost effective and not suitable for real-time continuous monitoring. The study compared the concentrations of benzene in the indoor and outdoor air reported from different countries. Though the higher concentrations of benzene noticed in the survey were mostly from Asian countries, both in the case of indoor and outdoor air, the concentrations were not statistically different across the various continents. Based on the analyzed data, the average benzene level in the ambient air of Asian countries (371 μg/m3) was approximately 3.5 times higher than the indoor benzene levels (111 μg/m3). Similarly, the outdoor to the indoor ratio of benzene level in European and North American Countries were found to be 1.2 and 7.7, respectively. This compilation will help the policymakers to include/revise the standards for benzene in future air quality guideline amendments.

“…In recent decades, indoor HCHO concentration has been investigated intensively all over the world (Brdarić et al, 2019;Lee et al, 2018;Norbäck et al, 2017;Qin et al, 2020;Yang et al, 2015). Studies demonstrate that the variation of HCHO concentration in indoor air varies depending on the age and type of buildings, ventilation, indoor air temperature, relative humidity (RH) etc.…”

“…VOCs originate from both indoor and outdoor sources [7]; they are of particular concern due to their potential impact on human health. Formaldehyde and benzene [8], for example, are some of the most studied pollutants since they are classified in Group 1 of human carcinogens by the International Agency for Research on Cancer [9]. For many of these chemicals, the risk on human health and comfort is almost unknown and difficult to be predicted because of the lack of toxicological data.…”

This article addresses the issue of VOC emissions from upholstery materials (natural leather) used for the manufacturing of upholstered furniture. The main intention of this paper is to compare VOC emissions released from different types of natural upholstery leathers. This research has assessed the impact of various factors (e.g. the organic origin of leather, the type of tanning, the type of upholstery leather and the leather finish etc.) on the amount of VOC emissions from natural leathers used for the production of upholstered furniture. 1 m 2 samples of natural leather were prepared for testing before being placed into a small test chamber (1 m 3 volume). VOC emission measurements were taken in a small test chamber with predefined conditions (an ambient temperature of 23ºC and 50% relative air humidity). With the use of sorbent Tenax TA were, the values of VOC emissions released by the test sample of different types of leather into desorption tubes was then recorded. VOC emissions were analysed in an Agilent GC 6890 N gas chromatograph using an Agilent 5973 Network mass spectrometer using cryofocusing, thermal desorption and a GC-MS data library (NIST 05). The analyses conducted provide qualitative and quantitative data regarding the concentration of selected VOC representatives measured in µg.m -3 . The quantitative difference in all emitted organic compounds is shown by the measured values of the TVOC parameter.
