Evaporation of gasoline at gas stations is the origin of air pollutants in gas station environment. This study is intended to estimate BTEX emission levels at gas stations and mapping BTEX emissions at all gas stations in Semarang. 4.09 D Tank Program with supported data collected by survey and secondary data used to calculate the estimated emissions. We also measured BTEX levels in the gas station location sample with charcoal tubes as adsorbent and PCXR4 mini pump sampler. The emissions from dispensers and storage tanks in gas stations have different emission characteristics. The amount of emissions from dispensers for VOC pollutants is 3.9261 tons/year and benzene is 0.0561 tons/year (case study UNDIP gas station). While the emission from a storage tank for VOC pollutants was 232.91 tons/year, benzene was 1.79 tons/year, toluene was 33.36 tons/year, ethylbenzene was 0.39 tons/year, and xylene was 1.43 Tons/year. The estimation results of the model with the results of direct BTEX measurements in the field showed that the field measurement results were smaller than those estimated. Some assumptions used in the calculations contribute to estimating uncertainty. The measured BTEX concentration still meets the quality standard (Minister of Manpower and Transmigration Regulation No. 13 of 2011).

The discussion about the use, or not, of Personal Protective Equipment (PPE) by gas station attendants has been growing, in the contemporary context, due to the expansive increase in the consequences generated by the absence of this essential equipment at gas stations. The present study highlighted the importance of raising awareness among the attendants regarding their working conditions, mainly due to the high exposure to toxic compounds. At this core, resistance to use PPE by these workers comesfrom sociocultural issues that notoriously influence the conditionsimposed by this service. In this logic, the case study, determined by the book of Research Methodology by Marconi and Lakatos (2003), thistheme is based on data collection at gasstationsin the city of Salvador- BA, in 2021, to highlight the situations faced by these professionals and, consequently, the impacts on their quality of life and health. The resistance to the use of this equipment harms the present and future well-being of the attendants.

Exposure to benzene, toluene, ethylbenzene, and xylene (BTEX) has been reported in gas stations. Exposure to BTEX can result in adverse health outcomes in workers such as cancer and neurological effects. The health risk assessments of exposure to BTEX could be useful in choosing suitable control measures. In this review, data from previous studies of gas station environments in Iran were collected from years 2000 to 2020. The health risk assessments were conducted through the estimation of cancer and noncancer risks using a Monte Carlo simulation based on the US Environmental Protection Agency method. The results showed that exposure to BTEX in some cities of Iran was greater than the occupational exposure limits. The results of cancer risk assessments demonstrated that cancer risk was not increased. However, results of noncancer risk assessments demonstrated that neurological toxicity from exposure to BTEX was significant in different cities of Iran. The health risk assessments indicated that workers at gas station are at health risk.

 AbstrakPenggunaan kendaraan bermotor roda dua di Indonesia semakin berkembang pesat. Semakin tinggi tingkat penggunaan transportasi yang beroperasi disuatu daerah, maka akan semakin tinggi pula potensi pencemaran udara di daerah tersebut. Jika pembakaran pada kendaraan bermotor tidak sempurna maka dapat dihasilkan senyawa yang berbahaya yaitu benzene (C6H6), toluene (C7H8), ethylbenzene (C8H9), dan xylene (C8H10) atau biasa disingkat BTEX. Tujuan penelitian ini adalah untuk mengidentifikasi senyawa BTEX dan senyawa hidrokarbon lainnya dalam asap kendaraan bermotor dengan menggunakan kromatografi gas-spektrometer massa (GC-MS). Hasil identifikasi menunjukkan adanya hubungan yangsangat kuat antara standard dengan hasil pengukuran yaitu dengan R2 di atas 0,99. Identifikasi menunjukkan senyawa BTEX yang terbentuk adalah Benzene, Toluene, Etil Benzene, Xylene.Kata kunci: kendaraan bermotor, hidro karbon, BTEX, GC-MS.AbstractThe use of two wheels motorized vehicles or motorcycles in Indonesia is growing rapidly. It has been known that the greater the number of two wheels motorized vehicles the higher the potential for air pollution. If the combustion occur incomplete, hazardous compounds can be generated, namely benzene (C6H6), toluene (C7H8), ethylbenzene (C8H9), and xylene (C8H10) or commonly abbreviated BTEX. The purpose of this study was to identify BTEX compounds and other hydrocarbon compounds in motor vehicle fumes using gas chromatography-mass spectrometers. The identification results indicate a very strong relationship between the standard and the measurement results, with R2 above 0.99. Identification shows that BTEX compounds formed are Benzene, Toluene, Ethyl Benzene, Xylene. Keywords: motorcycles, hidro karbon, BTEX, GC-MS.

The technological revolution 4.0 brings great opportunities, but also cybercrimes to economic sectors, especially to banks. Using secondary data and survey results of 305 bank clients, the main findings of this paper are: (i) there are several types of cybercrimes in the banking sector; (ii) Vietnam is one of the top countries worldwide having hackers and being attacked by hackers, especially the banking sector. Three most common attacks are skimming, hacking and phishing. Number of cybercrime attacks in Vietnam are increasing rapidly over years; (iii) Vietnamese customers are very vulnerable to cybercrime in banking, as more than 58% seem to hear about cybercrimes, and how banks provide services to let them know about their transactions. However, more than 50% do not have any deep knowledge or any measures for preventing cybercrime; (iii) Customers believe in banks, but do not think that banks can deal with cybercrime issues well. They still feel traditional transactions are more secure than e-transactions; (iv) the reasons for high cybercrimes come from commercial banks (low management and human capacity), supporting environment (inadequate), legal framework (not yet strong and strict enough on cybercrimes), and clients (low level of financial literacy). Therefore, several solutions should be carried out, from all stakeholders, for improving the cybersecurity in Vietnamese banks.
