“…Analysis of volatile organic compounds (VOCs) present in industrial/ waste odorous emissions has become an increasingly studied topic due to their possible impact on human health [1][2][3][4][5][6][7][8]. An increasing number of industrial/waste management activities are subject to odour emission monitoring.…”

“…Aside from methane, non-methane hydrocarbon (NMHC) is another major issue for the environment, because it re ects the level of pollution from tra c (Hamid et al, 2020) and urban activity (Kansal, 2009;Waked et al, 2016). In a broader aspect, there is a wide variety of VOCs in ambient air near industrialized areas due to the use of chemicals (Ou-Yang et al, 2020). For example, the species of chemical emissions from petroleum chemical industries (Wei et al, 2018) are very different from those released from electronic industries (Jian et al, 2015).…”

This paper presents the design and field monitoring results using a compact gas chromatograph equipped with a novel tandem sampler that enables the simultaneous and continuous analyses of methane at ppmv level and multiple volatile organic compounds (VOCs) at ppbv level. The tandem sampler consists of a capillary preconcentrator filled with multistage adsorbents and a subsequent sampling loop. In this system, ambient methane breakthroughs the adsorbents and fills the sampling loop while the ppbv levels of VOCs are preconcentrated by adsorbents. The field study was conducted in a developing industrial area near a midsize township that was surrounded by paddy fields. Continuous analysis data provided in 25 min intervals revealed the independent sources of various industrial chemicals. The rapid analysis capability of this instrument can establish concentration distribution patterns within only a few days of field study. Right skewed concentration distributions of low ppbv VOCs and a symmetrical Gaussian distribution of methane at ppmv using this single near real-time GC instrument. This study describes the development of a fast and cost-effective method to simultaneously assess the real-time variations in VOCs and methane in general environments.

“…Due to the relevance of their emissions, it is worth focusing on samples of gaseous emissions from oil refineries [ 20 , 21 , 22 ]. Indeed, the oil refining industry, at the European level, is responsible for about 2% of the overall VOCs emission generated by industrial activities [ 23 ].…”

Refineries are characterized by relevant odour impacts, and the control and monitoring of this pollutant have become increasingly important. Dynamic olfactometry, a sensorial analysis that involves human examiners, is currently the most common technique to obtain odour quantification. However, due to the potential presence of hazardous pollutants, the conduction of occupational risk assessment is necessary to guarantee examiners’ safety. Nevertheless, the occupational risk for olfactometric examiners, specifically correlated with oil refineries emissions, has not been investigated yet. Therefore, this paper applies a new methodology of risk assessment for workers involved in dynamic olfactometry, focusing on odorous refineries emissions. The chemical characterization of refinery emissions was obtained by TD-GC-MS, analysing odorous samples collected at different refinery odour sources. A database of chemical pollutants emitted from a refinery plant was built up, and the minimum dilution values to be adopted during the analysis of refinery odorous samples was calculated. In particular, this evaluation highlighted that, in this scenario, a non-negligible carcinogenic risk may exist for panellists exposed to refineries’ samples, and the carcinogenic risk is sometimes higher than what is acceptable. Therefore, a minimum dilution value between 1.01 and 5, according to the specific sample, must be set to guarantee the examiners’ safety.
