Gas Station

<p>Air pollutants exposure on the gas station generally comes from motor vehicle emissions, such as toluene, benzene, xylene or polycyclic aromatic hydrocarbons (PAH) compounds. These compounds are metabolized by the liver to form free radicals, thus are harmful to health. Gas station operators have a substantial risk of air pollutants exposure released by motor vehicle emissions. The objective of this research is to find out the levels of superoxide dismutase (SOD) in gas station operator on Semarang, Indonesia. This research was analytic observational cross-sectional study conducted from April to August 2015. The number of samples obtained in this research was 21 gas station operators and 10 volunteers who live in the countryside. Blood SOD levels biochemically determined using Randox kit SOD. The results showed that the average of SOD level in gas station operators was 0.76 u · mL<sup>–</sup><sup>1</sup> and volunteers was 0.87 u · mL<sup>–</sup><sup>1</sup>. Statistical test results of SOD levels showed the significant value p = 0.860. The SOD levels of gas stations operators are lower than the SOD levels of volunteers who live in the countryside. Gas stations operator does not significantly influence SOD levels.</p>

Bioindicators can be used to determine levels of air pollution of an area by analyzing the content of pollutants lead in bioindicators. Lichenes growing on the bark as bioindicators for measuring the concentration of lead in air pollutants resulting from motor vehicle emissions. The aim of research to determine differences in the levels of lead (Pb) using bioindicators Lichenes Madiun. Samples were taken by random sampling technique. Pb content measurement using Atomic Absorption Spectrophotometer (AAS). The results showed Pb levels in different areas of the City of Madiun there are significant differences. Traffic levels affect the levels of Pb .

In the context of the outbreak of coronavirus disease 2019 (COVID-19), strict lockdown policies were implemented to control nonessential human activities in Xi’an, northwest China, which greatly limited the spread of the pandemic and affected air quality. Compared with pre-lockdown, the air quality index and concentrations of PM2.5, PM10, SO2, and CO during the lockdown reduced, but the reductions were not very significant. NO2 levels exhibited the largest decrease (52%) during lockdown, owing to the remarkable decreased motor vehicle emissions. The highest K+ and lowest Ca2+ concentrations in PM2.5 samples could be attributed to the increase in household biomass fuel consumption in suburbs and rural areas around Xi’an and the decrease in human physical activities in Xi’an (e.g., human travel, vehicle emissions, construction activities), respectively, during the lockdown period. Secondary chemical reactions in the atmosphere increased in the lockdown period, as evidenced by the increased O3 level (increased by 160%) and OC/EC ratios in PM2.5 (increased by 26%), compared with pre-lockdown levels. The results, based on a natural experiment in this study, can be used as a reference for studying the formation and source of air pollution in Xi’an and provide evidence for establishing future long-term air pollution control policies.

Objective: The purpose of this research is to investigate the correlation between fat intake and plasma superoxide dismutase (SOD) enzyme activity with telomere length of Minangkabau ethnic men in West Sumatera, Indonesia. Materials and Methods: This cross-sectional study was conducted in Padang City in 2016, using a sample of 107 Minangkabau ethnic men, aged between 40 and 50 years. The total fat, saturated fatty acids (SFA), monounsaturated fatty acid (MUFA), and polyunsaturated fatty acid (PUFA) intake were collected using a food frequency questionnaire, and blood sample analysis to measure telomere length and plasma SOD activity. Results: This research indicated that an average telomere length was 584.59±305.92 bp, fat intake consists of total fat was 27.01±6.68% calorie, SFA was 24,7510.07% calorie, MUFA was 10.24±5.41% calorie, and PUFA was 7.35±3.54% calorie. Average of plasma SOD activity was 5.85±3.41 u/mL. There were no correlations between fat intake (total fat, SFA, MUFA, and PUFA) with telomere length (p>0.05), but there was a significant positive correlation between plasma SOD enzyme activity with telomere length (r=−0.202, p=0.037). Conclusion: Fat intake within normal limits does not correlate with telomere length, and plasma SOD activity is a risk factor for telomere shortening in ethnic Minangkabau men.

ABSTRACT Background: Development during infancy occurs rapidly. Parent ability to meet their nutritional needs is needed to obtain optimal infants development. This study was to investigate the difference of development in children aged 6 months received exclusive breastfeeding versus formula milk Subjects and Method: A cross-sectional study was conducted at Ciptomulyo health center, Malang, East Java, from April to May 2017. A sample of 17 infants who received exclusive breastfeeding and 19 infants who received formula milk was selected by total sampling. The dependent variable was child development. The independent variables were exclusive breastfeeding and formula milk. Child development was measured by Denver Development Screening Test. Mean difference of child development between groups was measured by Mann Whitney. Results: Development score in children aged 6 months who received exclusive breastfeeding (Mean= 0.53; SD= 0.24) was higher than children who received formula milk (Mean= 0.47; SD= 0.01), and it was statistically significant (p= 0.003). Conclusion: Development score in children aged 6 months who received exclusive breastfeeding is higher than children who received formula milk. Keywords: child development, exclusive breastfeeding, formula milk Correspondence: Milatur Rosyidah. Masters Program in Public Health, Universitas Sebelas Maret. Jl. Ir.
