ABSTRACTThe nineties have brought us to an era of environmental crisis. We are faced with problems of air pollution, both indoor and outdoor, acid rain, water pollution, hazardous wastes, toxic landfills and leaking storage tanks in our soil, to name a few. Our rapid advances into the industrial and technological age have contributed to these problems. However, our advancing technology in the areas of remediation and such “green” engineering tools as ceramic membranes can certainly make a significant contribution in terms of environmental clean-up and a healthier world.

The balanced environmentally sustainable economic development of Ukraine can be achieved by increasing the efficiency of the nature protection efforts, which requires the improved methods for assessment, modeling and forecasting of environmental performance and environmental pollution indicators. The article’s objective is to make a statistical forecasting of environmental pollution indicators in Ukraine, to outline the areas of nature protection work in this country. Air pollution, water pollution and hazardous wastes in Ukraine are forecasted considering the main factors of influence, selected with reference to the Strategy of the State Environmental Policy of Ukraine: GDP, the number of implemented resource-saving technologies, energy intensity of GDP, current spending on environmental protection. The project estimates for air pollution, water pollution and hazardous wastes were derived by use of regression models and factors projection. Results of the forecasting show that the emission of pollutants and carbon dioxide in the air, water pollution and pollution with hazardous wastes will be significantly reduced by 2022 if the current trends and patterns of development remain unchanged. Results of the forecasting confirm the need to introduce a series of measures concerned with waste treatment, air pollution and water pollution, to improve the regulatory system in nature protection activities in Ukraine.

Although coal has powered the nation for generations and today offers well-paying jobs—often the best opportunities in more rural areas—coal negatively affects human health and the environment at every point in its life cycle: when it is mined, processed, transported, burned, and discarded (Freese, Clemmer, and Nogee 2008). Local communities— often low-income communities and/or communities of color—have for decades borne the brunt of these negative impacts, including air pollution, water pollution, and work- place injuries, illnesses, and fatalities.

The presence of dump stations around resident's houses besides resulting air pollution, it is also affectingthe cleanliness of water used by society to meet their daily needs. Location where we researched is at ex-Pasirimpun Dump Station, Karang Pamulang Village, Kecamatan Cicadas, Bandung. Although Pasirimpun Dump Station has been closed and turned function into Taman Abdi Negara, it is feared that there is a water pollution caused by leach zone. Geophysical measurements by geoelectric method are performed to prove the leaching zone. This study aims to determine the depth of the leaching zone, its position against the groundwater level, and what potential harm can caused by the leaching zone. The methodology that is used are direct observation, interviews, and literature studies. Our measurements is done by using schlumberger conguration and Induced Polarization (IP) method on morphology that tend to be at with a length of 141 meters stretch and a spaceof 3 meters. Groundwater faces are mapped to be correlated with the depth of the existing leaching zone. From the results of literature studies, there is a leaching zone in the area with a depth of about 30 meters. By knowing this leaching zone, we hope that there will be cooperation between government and society to avoidthe impacts of leaching zone on the water which they consumed. One way to know, is to drill deeper water level from the leach zone.

Air pollution is a well-known problem for human health, especially for children living in highly polluted urban areas. This study aimed to assess the relationship between airborne pollutants concentration and biomarkers of DNA damage in the buccal mucosa cells of pre-school children. DNA damage was investigated with comet test in saliva leukocytes taken from sputum of 3- to 6-year-old children living in Brescia, Northern Italy, collected during two consecutive winter seasons (2012–2013). The daily levels of PM10, PM2.5, NO2, CO, SO2, benzene and O3 in urban air were collected for the whole period. A questionnaire filled in by the children’s parents was used to evaluate indoor and outdoor exposure. DNA damage in saliva leukocytes was evaluated in 152 children and the means of tail intensity and visual score as DNA damage were 6.2 ± 4.3 and 182.1 ± 30.9, respectively. No demographic and indoor or outdoor exposure variable was associated with the two measures of DNA damage. No significant association between air pollution and DNA damage in children’s buccal leukocytes was found. In this study, the comet assay does not appear to be a valuable biomarker to detect DNA damage in children exposed to high levels of air pollutants, such as PM10, PM2.5 and NO2.

Air and water pollution have detrimental effects on health, while physical activity opportunities have a positive relationship. The purpose of this study was to explore whether physical activity opportunities moderate the relationships among air and water pollution, and measures of health. Aggregate data were collected at the county level in the United States (n = 3104). Variables included the mean daily density of fine particle matter (air pollution), reported cases of health-related drinking water violations (water pollution), subjective ratings of poor or fair health (overall health), the number of physically and mentally unhealthy (physical and mental health, respectively), and the percentage of people living in close proximity to a park or recreation facility (access to physical activity). Air and water pollution have a significant positive effect on all measures of residents’ poor health, while physical activity opportunities only have a negative effect on overall health and physical health. Access to physical activity only moderates the relationship between air pollution and all health outcomes. Since physical activity behavior can be more rapidly changed than some causes of pollution, providing the resident population with better access to physical activity can represent an effective tool in environmental health policy.
