Abstract:
This paper has two parts. The first briefly describes geochemical and geophysical investigations at the territory of gold tailings impoundment produced with cyanidation by the abandoned Komsomolsk Gold Extraction Plant, KGEP (Kemerovo region, Russia). The second part reflects on our recent studies in the area of the low-level waste repository of the Novosibirsk Plant of Chemical Concentrates, NPCC (Novosibirsk, Russia). The relatively low sulfide content in the Komsomolsk tailings result in a low acid producing potential (AP). The situation is complicated by the displaced Berikul tailings of the former Berikul GEP. In these tailings, the sulfide content is 25%, they have high AP and the formation of acidic surface ponds (pH ∼2) with high concentrations of metals and metalloids (as up to 4.1 g/L). Based on electrical resistivity tomography, the uncontrolled leakage of acidic and highly mineralized solutions through a natural geological fault into groundwater horizons was revealed. Uranium contamination of groundwater is prevalent worldwide because of uranium extraction for nuclear energy and weapons. An experimental modeling has been carried out to convert U(VI) to species with low solubility via metabolic process. The removal of nitrates, sulfates and U(VI) reduction due to the stimulated microbiological activity was proved. Within 13 days after the start of serum injections, reducing conditions was indicated and the sharp decrease in nitrate concentrations was observed. Sulfate reduction was established approximately 50 days later as indicated by the increase in sulfide concentrations. Model calculations by computer code “HCh” have approved precipitation of β-UO2.25(s) at Eh+115 mV and precipitation of UO2(s) after the fall of Eh to -397 mV. The developed model can be used as a starting point of assessment of the redox sensitive elements behavior in the process of bioremediation.

Abstract:
Mesoporous TiO2 films were dip-coated diverse conductive glass substrates such as Indium Tin Oxide (ITO) and F-doped Tin Oxide (FTO) as well soda-lime glass (SL). The mesoporous TiO2 films were assessed for their photodegradation for CH3CHO oxidation in gas phase as a probe molecule and compared with both nonporous TiO2 film deposited on FTO and commercial Pilkington Glass. The thickness and surface areas of the mesoporous TiO2 films was determined to be around 228±10, 184 ±15 and 205 ±15 nm and 215, 352 and 295 m2/cm3 deposition on SL, FTO and ITO, respectively. The prepared mesoporous TiO2 film deposited on SL, FTO and ITO are more photonic efficiency than nonporous TiO2 film and Pilkington Glass. The photonic efficiency of mesoporous TiO2 film is the following order FTO> ITO > SL. The photonic efficiency of TiO2/FTO is greater 21 and 3 times than that commercial Pilkington Glass ActivTM and nonporous TiO2/FTO, respectively. In addition, the outstanding photocatalytic activity of mesoporous TiO2/FTO substrate is shown in recycling tests in which no significant reduce in the photonic efficiency was recognized after five repetitive times for 10 hours continuously, indicating a promising materials for potential applications.

Abstract:
Air pollution can directly or indirectly affect human health, causing physical discomfort and leading to disease or even death. Studies have shown that when the human body is exposed to highly polluted air for a long time, the mortality rate increases. Furthermore, air pollution has become the fourth primary risk factor for all deaths after heart attack, dietary risk and smoking, according to the latest statistics. In recent years, there have been frequent haze weather events in many places where the air quality was mostly between ‘moderate’ and ‘unhealthy for sensitive groups. Studies show that under such air conditions, the mortality rate from cardiovascular and cerebrovascular diseases and the prevalence of asthma and respiratory diseases both increase. This paper‘s foremost objective focus on air pollutants classifications: Primary and Secondary defining its various sources like: Acid rains, Green House effect, Smog and its types, …etc. The global greenhouse effect – also called global warming – concerns us now because atmospheric CO2 concentrations are increasing faster than ever, and because most of the increase is due to industrial growth. Many scientists predict that unless we do something to impede global warming, it may: – Increase the number and intensity of dangerous heat waves – Increase severe storm activity – Damage certain crops – Raise the average sea level. These in turn will increase weather- related deaths, damage coastal cities and towns, and ruin coastal ecosystems. It is still hard to find a consensus on global warming. Different experts use different models and even different data sets. Some believe global warming is imminent and predict that it will cause catastrophic damage. Others are far less concerned. Until the science is more definitive, the global-warming debate will continue to be governed by Robinson’s Rule of Expert Testimony: “For any given PhD, there is an equal and opposite PhD. While, the at-most objective of the paper will focus on applying Environmental Management system to control air pollution.
