Internal Mechanism

Carbon monoxide was one of the indicators of air pollution that most often comes from motor vehicles. Indirectly, increasing the number of motorcycles would be followed by an increase in the number of workshops that provide maintenance services. The process of maintenance and repair in the workshop causes carbon monoxide (CO) levels in the air to be higher from the standard so it was easily inhaled by workers and the internal mechanism reacts became carboxyhemoglobin (HbCO). This study aims to analyze the effect of CO levels in the workshop air and smoking habits of workers on HbCO levels in the blood of workshop mechanic workers. This research was an observational analytic study with 18 respondents as workshop mechanic workers who were male. Respondents in this study were identified based on age, years of service, length of work, use of Personal Protective Equipment (PPE), and nutritional status. The results showed that most respondents aged 25-36 years -old (38,9%), had a year of service ≥ 5 years (55,6%), had smoking habits (72,2%), did not use PPE (88,9%) and had a normal nutritional status (47,2%). CO levels in the air had a significant correlation on HbCO levels (p <0,000) as well as smoking habits also had a significant correlation on HbCO levels (p <0,000). It was recommended for workers to reduce smoking habits, improved healthy lifestyles, and used masks to reduce exposure to pollutants.

Test Result

Background: Scavengers in landfills have high risk to pollution exposure. Carbon monoxide (CO) is one of important pollutants produced by burning process. Exhaled CO levels in scavengers is predicted to increase, caused by pollution exposure in workplace area. There has been no data on exhaled CO levels in scavengers, especially in Bantar Gebang, Bekasi.Methods: This study used cross-sectional design to the scavengers who work and live in Ciketing Udik, Bantar Gebang, Bekasi. This study was conducted in January - March 2015, by doing interviews and giving questionnaires, and conducted exhaled CO test.Results: Total sample was 108 subjects. Exhaled CO test result was 46 subjects (42.6%) had exhaled CO 5-10 ppm, 36 subjects (33.3%) > 10 ppm, and 26 subjects (24.1%) ≤ 4 ppm. Multivariate analysis between exhaled CO levels with characteristics of the subjects found smoking habits were significantly correlated with CO exhalation levels (p=0,000).Conclusion: There were 33.3% scavengers who had exhaled CO > 10 ppm. Smoking habits were the only factor that significantly correlated with CO in scavengers’ exhalation.

The purpose of this study was to evaluate the physiological strain index (PSI) for different age groups during exercise-heat stress (EHS). PSI was applied to three different databases. First, from young and middle-age men (21 ± 2 and 46 ± 5 yr, respectively) matched ( n = 9 each, P > 0.05) for maximal aerobic power. Subjects were heat acclimated by daily treadmill walking for two 50-min bouts separated by 10-min rest for 10 days in a hot-dry environment [49°C, 20% relative humidity (RH)]. The second database involved a group ( n = 8) of young (YA) and a group ( n = 7) of older (OA) men (26 ± 1 and 69 ± 1 yr, respectively) who underwent 16 wk of aerobic training and two control groups ( n = 7 each) who were matched for age to YA and OA. These four groups performed EHS at 36°C, 40% RH on a cycle ergometer for 60 min at 60% maximal aerobic power before and after training. The third database was obtained from three groups of postmenopausal women and a group of 10 men. Two groups of women ( n = 8 each) were undergoing hormone replacement therapy, estrogen or estrogen plus progesterone, and the third group ( n = 9) received no hormone replacement. Subjects were over 50 yr and performed the same EHS: exercising at 36°C, 40% RH on a cycle ergometer for 60 min. PSI assessed the strain for all three databases and reported differences were significant at P < 0.05. This index rated the strain in rank order, whereas the postacclimation and posttraining groups were assessed as having less strain than the preacclimation and pretraining groups. Furthermore, middle-aged women on estrogen replacement therapy had less strain than estrogen + progesterone and no hormone therapy. PSI evaluation was extended for men and women of different ages (50–70 yr) during acute EHS, heat acclimation, after aerobic training, and inclusive of women undergoing hormone replacement therapy.

Plastic pollution is an emerging stressor that increases pressure on ecosystems such as coral reefs that are already challenged by climate change. However, the effect of plastic pollution in combination with global warming is largely unknown. Thus, the goal of this study was to determine the cumulative effect of microplastic pollution with that of global warming on reef-building coral species and to compare the severity of both stressors. For this, we conducted a series of three controlled laboratory experiments and exposed a broad range of coral species (Acropora muricata, Montipora digitata, Porites lutea, Pocillopora verrucosa, and Stylophora pistillata) to microplastic particles in a range of concentrations (2.5-2,500 particles L-1) and mixtures (from different industrial sectors) at ambient temperatures and in combination with heat stress. We show that microplastic can occasionally have a negative effect on the corals' thermal tolerance. In comparison to heat stress, however, microplastic constitutes a minor stressor. While heat stress led to decreased photosynthetic efficiency of algal symbionts, and increased bleaching, tissue necrosis, and mortality, treatment with microplastic particles had only minor effects on the physiology and health of the tested coral species at ambient temperatures. These findings underline that while efforts to reduce plastic pollution should continue, they should not replace more urgent efforts to halt global warming, which are immediately needed to preserve remaining coral reef ecosystems.
