Abstract

Objective: To investigate coliform contamination in drinking water from vending machines in the Rajvithi area of Bangkok.Study Design: Cross-sectional studyMethods: Associated environmental factors were observed and self-administered questionnaires conducted. In total, 123 drinking-water samples were collected to test coliform bacteria contamination.Results: Coliform bacteria were detected in 28.5% of samples. Links were found between coliform contamination and filter cleaning practices in 57 maintenance persons' responses. Filters cleaned < 3 times per year were at higher risk of coliform contamination (OR 14.49, 95% CI 1.76-125.00). A negative association was found between coliform contamination and vending-machine filters' being cleaned within 100 days (OR 0.21, 95% CI 0.05-0.83).Conclusion: A negative association was found between coliform contamination and vending-machine filters' being cleaned within 100 days (OR 0.21, 95% CI 0.05-0.83). These results emphasized the importance of effective vending-machine maintenance and monitoring drinking-water quality.

Abstract

Carbon monoxide (CO) is the main pollutant from motor vehicle emissions which is dangerous if inhaled by humans. This study aims to analyze the ecological and health risks caused by carbon monoxide gas pollution to parking attendants on roads in Gorontalo City. This type of research is an observational study using the Ecological Risk Assessment (ERA) and Health Risk Assessment (HRA) approaches through field studies. The number of samples was 60 respondents and air samples were taken from 12 locations and each location consisted of 2 points. Data were analyzed descriptively through studies (ERA) and (HRA). The results showed that there were 8 locations that had CO concentrations that exceeded the threshold value. Thus the level of CO on roads in Gorontalo City is included in the unsafe category. Characterization of ecological risk due to CO exposure on roads in Gorontalo City is classified as dangerous for the environment where 4 locations are in the low hazard category (HQ 0.1-1.0) and 8 locations are in the medium hazard category (HQ 1.1-10). The highest real-time exposure CO intake was at the Jamu Solo Store location, namely 1.8501799100 mg/kg/day with an RQ value of 2.2291324200 (at risk), while the lowest was at the Extra Bakery location 0.0746788000 mg/kg/day with an RQ value of 0.0899744600 (no risk). It is recommended for parking attendants to wear masks while working and reduce smoking habits.

Abstract

Smoking leads to disease and disability as well as harm nearly every organ of the body. Furthermore, smoking of tobacco is known to cause pulmonary dysfunction and lead to complications, pain, or even death. This study aimed to measure the risk factors for the respiration of carbon monoxide among smokers. A cross-sectional design was implemented by involving 156 smokers in Karyajaya Subdistrict, Palembang City. The dependent variable was carbon monoxide levels (ppm), while the independent variables were smoking frequency, duration, and the last period of smoking. The carbon monoxide levels (ppm) measured with a PiCO + Smokerlyzer® device from Bedfont Scientific Limited were the research tool and the independent variables of the questionnaire. The Pearson Correlation and multiple linear regression were used for the analysis. The results of the multiple linear regression analysis revealed that smoking duration assessment is related to carbon monoxide respiration after controlling smoking frequency, the last period of smoking, and the distance of residence to sources of exposure. The smoker's respiration of carbon monoxide level was 72.5% influenced by the duration, frequency, last period of smoking, and distance of residence to sources of exposure. Reducing the frequency of smoking and stopping may prevent and control carbon monoxide respiration.

Abstract

The COVID-19 pandemic, originated in China, has spread to worldwide, including Indonesia. Until July 2021, the growth rate has been gradually increasing, and cases have been found in all 34 provinces of Indonesia. This cross-sectional study aimed to investigate the knowledge, attitude, and practices (KAP) of health personnel in the primary health care towards the COVID-19 pandemic in Indonesia using online self-report questionnaire. A total of 440 respondents contributed to this online survey. The average level of KAP were 7.7 out of 10.0, 14.3 out of 15.0, and 31.9 out of 36.0, respectively. There was no significant association between respondents’ characteristics (sex, marital status, and age) and their KAP for all variables showed p-value>0.05. It can be concluded that the level of KAP was good, despite the respondents’ characteristics that had no association with KAP.
