“…These results are in alignment with the results from our Radiello findings except for ethylbenzene. BTEX concentrations measured in a wastewater treatment plant in Turkey by Ulutaş et al revealed concentrations of BTEX components were 2.78, 11.6, 3.72, and 11.9 µg/m 3 for benzene, toluene, ethylbenzene, and xylenes, respectively [36].…”

This study assessed the cleaner and sustainable environment by measuring emission levels of benzene, toluene, ethylbenzene, and xylene (BTEX) from informal food traders using charcoal as the primary source of energy at a flea market in Fordsburg, Johannesburg. Volatile organic compounds (VOCs) were measured using a real-time monitor (MiniRae 3000 photoionization detector); an indoor air quality (IAQ) monitor was used to monitor environmental parameters and passive samplers in the form of Radiello badges, which were used to determine BTEX emissions from charcoal used during food preparation. Measurements were taken at 1.5 m above ground assuming the receptor’s breathing circumference using PID and Radiello. PID data were downloaded and analyzed using Microsoft Excel (Version 2019). Radiellos were sent to the laboratory to determine the BTEX levels from the total VOCs. The total volatile organic compound (TVOC) concentration over the combustion cycle was 306.7 ± 62.8 ppm. The flaming phase had the highest VOC concentration (547 ± 110.46 ppm), followed by the ignition phase (339.44 ± 40.6 ppm) and coking with the lowest concentration (24.64 ± 14.3). The average BTEX concentration was 15.7 ± 5.9 µg/m3 corresponding to the entire combustion cycle. BTEX concentrations were highest at the flaming phase (23.6 µg/m3) followed by the ignition (13.4 µg/m3) and coking phase (9.45 µg/m3). Ignition phase versus the flaming phase, there was a significant difference at 95% at a p-value of 0.09; ignition phase versus the coking phase, there was a significant difference at 95% at a p-value of 0.039; and coking phase versus the flaming phase, there was a significant difference at 95% at a p-value of 0.025. When compared to the occupational exposure limits (OELs), none of the exposure concentrations (BTEX) were above the 8 h exposure limit. The findings of this study suggest that charcoal, as a source of energy, can still be a useful and sustainable fuel for informal food traders. Shortening the ignition and flaming phase duration by using a fan to supply sufficient air can further reduce exposure to VOCs.

“…Continuous sampling is based on the association of the sampling and analysis systems through an instrument called a monitor, analyzer or continuous sampler, placed at the sampling site for a period suitable for the desired measurements. The advantage of this method is the measurement of variations in pollutant concentrations over a short period of time, being useful in identifying concentration peaks, warning situations and accidents, in assessing the conformity of air quality with short-term standards, in providing data for modeling and calibration, and in assessing the temporal distribution of atmospheric levels of a given pollutant [47,[49][50][51].…”

Hydrogen sulfide (H2S) is a colorless gas with a characteristic unpleasant odor (like rotten eggs) that is extremely toxic and corrosive. Due to its toxicity, H2S irritates the eyes and/or affects the nervous and respiratory systems. Concentrations on the order of 700 to 1500 ppm can kill a human in a matter of minutes. The media has presented several examples of H2S leaks that jeopardize human lives, threaten the integrity of industrial assets, and endanger the environment. This work aims to show the importance of knowledge of the origins and physicochemical properties of hydrogen sulfide in the direct and indirect relations with man, the environment and industrial equipment.

“…Climate change, in combination with urbanization, population growth, and water consumption is projected to intensify the strain on natural water resources [4,5]. Interannual and intra-annual changes in surface waters can be dramatically affected by climate change and human activity with far-reaching implications for habitats and human society [6,7].…”

The current work aims to examine the effect of meteorological parameters as well as the temporal variation on the Burdur Lake surface water body areas in Turkey. The data for the surface area of Burdur Lake was collected over 34 years between 1984 and 2019 by Google Earth Engine. The seasonal variation in the water bodies area was collected using our proposed extraction method and 570 Landsat images. The reduction in the total area of the lake was observed between 206.6 km2 in 1984 to 125.5 km2 in 2019. The vegetation cover and meteorological parameters collected that affect the observed variation of surface water bodies for the same area include precipitation, evapotranspiration, albedo, radiation, and temperature. The selected meteorological variables influence the reduction in lake area directly during various seasons. Correlations showed a strong positive or negative significant relationship between the reduction and the selected meteorological variables. A factor analysis provided three components that explain 82.15% of the total variation in the data. The data provide valuable references for decision makers to develop sustainable agriculture and industrial water use policies to preserve water resources as well as cope with potential climate changes.
