PRODUCTION OF CHEMICAL EMISSIONS OF BLACK-COAL MINE AND THEIR INFLUENCE ON THE PUBLIC HEALTH IN THE CONDITIONS OF THE OSTRAVA INDUSTRIAL REGION

BACKGROUND: Post-coal mine activities must be carried out by considering good management principles, to avoid negative environmental impacts, especially to avoid land surface imbalance, to avoid destruction of flora and fauna, and more importantly, to maintain the public health. The post-mining regulations based on the priorities of public health and environmental sustainability are designed to increase the human resource quality for the interests of regional development. AIM: This study aims to describe the post-coal mine policy in East Borneo and to formulate the post-coal mine policy as a form of control over ex-mine land from the aspect of environmental health. METHODS: This study uses the qualitative research design. It is a sociolegal type of research with the case study approach toward the currently developing post-coal mine reclamation. This study uses the fishbone analysis. RESULTS: The results of this research show that the supervision toward the ex-mines is still weak. It leads to expanding environmental destruction and some of the companies’ ignorance toward reclamation and post-mining obligations. This condition impacts the water quality, as it is the people’s necessity in fulfilling their basic needs. CONCLUSION: There needs to be a post-coal mine regulation through policies which prioritize environmental sustainability and public health. It includes the optimization of the ex-mine supervision, new regulations as the implementation of the central government’s constitutional regulation, and inspection of environmental health in achieving quality human resources of the region.

Coal Mine Fire

Abstract Background In 2014, the Hazelwood coal mine fire was an unprecedented six-week severe smoke event in the Latrobe Valley, southeastern Australia. We aimed to determine whether maternal exposure to fine particulate matter (PM2.5) attributable to coal mine fire smoke was associated with gestational diabetes mellitus (GDM), hypertensive disorders of pregnancy and abnormal placentation. Methods We defined a cohort of all births >20 weeks in the Latrobe Valley from 1 March 2012 - 31 Dec 2015 utilising administrative perinatal data. Average and peak PM2.5 was assigned to residential address at delivery using a chemical transport model. Maternal, meteorological and temporal variables were included in final log-binomial regression models. Results 3,612 singleton pregnancies were included; 766 were exposed to the smoke event. Average maternal PM2.5 exposure was 4.4 µg/m3 (IQR 2.1). Average peak PM2.5 exposure was 44.9 µg/m3 (IQR 35.0). An interquartile range increase in average and peak PM2.5 was associated with a 7% and 16% increased likelihood of GDM respectively (Average PM2.5 95%CI 1.03, 1.10; <0.0001; Peak PM2.5 95%CI 1.09, 1.22; <0.0001). No association for hypertensive disorders or abnormal placentation was observed. Conclusions This is the first study to examine obstetric complications relating to a discrete smoke event. These findings may guide the public health response to future similar events. Key messages Exposure to a smoke event was associated with an increased risk of GDM. The public health implications may be substantial with a changing climate.
