    Opis:
    Background. The Thai government has been developing its Eastern Economic Corridor (EEC), which spans three provinces, with the aim of improving connections with other Asian nations. Since this strategic development, the number of trucks, private car, and passenger car registrations have continued to grow, with a corresponding increase in related to benzene, toluene, ethylbenzene, and xylene (BTEX). Objectives. This study aims to compare the levels of trans, trans-muconic acid (t, t MA); toluene (TU); mandelic acid (MA); and methyl hippuric acid (MHA) in the urine of gas station employees, considering demographic and occupational factors. Material and methods. These employees worked either near or away from the fuel dispenser, and there 100 people in each group. Data were collected using interviews and testing environmental air and urine samples for benzene, toluene, ethyl benzene, and xylene (BTEX). Results. The results showed that BTEX concentrations were just detectable in all 200 cases (100%). The mean (±SD) urine level of t, t MA was 449.28 (±213.32) μg/g creatinine, while the median (min-max) was 428.23 (95.58-1202.56) μg/g creatinine. The mean TU was 0.011 (0.001) mg/L, while the median (min-max) was 0.011 (0.010-0.013) mg/L. MA levels were higher inside the pollution control zone than they were outside the zone (p=.009). Employees who practiced poor personal hygiene had relatively high urinary toluene and MHA levels (p=.009) and those who did not wear personal protective equipment (PPE) had relatively high MA levels (p=.040). Conclusion. The results of this study revealed statistically significant biomarkers influencing the levels of t, t MA; TU; MA; and MHA in urine. The recommendations of this study are that employers should provide their employees with suitable PPE, check regularly to ensure that it is worn, and strongly encourage employees to take care of their sanitation. Employees should take appropriate breaks and days off to minimize their exposure to BTEX.

    Opis:
    Background. The main job of employees working in the area of fuel service stations is to provide refueling services to customers. Therefore, operators at petrol stations may be exposed to chemicals for long periods, potentially affecting their health in nervous system. Objectives. This study aims to assess the risk of benzene exposure to the nervous system in gas station operators. Data were collected from 100 fuel service personnel working at fuel dispensers and 100 employees working outside fuel dispensers, accounting to 200 cases. Material and methods. Data were collected using interview questionnaires. Urine samples were used for the analysis of t,t-muconic acid. Results. The results showed that t,t-muconic acid concentration is 431.23 ± 233.69 μg/g.cr (449.28 ± 213.32 μg/g.cr at fuel dispensers vs 413.18 ± 252.20 μg/g.cr outside fuel dispensers). The risk characterization results showed that most of the risks were at level 1 (low risk), as observed in 108 people (54.0%). The results of the analysis of the relationship between t,t-muconic acid concentrations classified by 3 levels of percentile and neurological disorders of the study group, the results showed that there was a statistically significant relationship (p-value <0.05). Conclusion. Therefore, the benzene neurotoxic risk assessment model could be utilized in field practice.

    Opis:
    Background. Petrol station (PS) workers are categorized as “unskilled labor”, which leads to low wages, economic instability, and a lack of adequate access to healthcare services (HCS) despite exposure to dangerous chemicals. A lack of information on the HCS access of PS workers is concerning. Objective. This study was undertaken to elucidate factors that influenced access to health care for fuel station workers in gas stations in Rayong province, Thailand. Material and methods. Two-hundred PS workers (100 serving at fuel dispensers and 100 working at other locations) were interviewed to evaluate their health conditions and factors affecting HCS access. The study cohort comprised 137 (68.5%) women and 63 (31.5%) men. The mean age was 30.29±10.97 years and the average monthly salary was 341.16 ± 124.72 USD. Results. The average distance between a respondent’s residence and government hospital was 10.49 ± 8.571 km. Most respondents (63.5%) were in good physical health, and 79.5% reported having “positive mental health”. However, 73% reported neurological disorders and 57% reported respiratory symptoms. During the previous 12 months, 44.5% of respondents had HCS access; 80.9% of participants reported that they had accessed HCS to obtain treatment for an illness, and 18% went for a health checkup. Government centers were rated as “satisfactory” by 78.8% of PS workers, and 75.5% received medical coverage under a social-security scheme. Moreover, 38.5% obtained HC information from their colleagues. HCS access was attributed to the cost of receiving HCS as well as the sex, marital status, illness severity of PS workers. Conclusions. Workers should have access to comprehensive HCS. Policy frameworks and systems for HCS should take account of employees’ sex, marital status, and the type and severity of their illnesses.
