The Impact

Over the pastdecade, particular attention has been paid to studies of the chemical composition of medical plants to identify the possible negative consequences of using raw plant material polluted with heavy metals for the production of medical drugs. In our study, we analyzed the chemical composition of the medical plants growing in the impact area of the Novocherkassk power station. Specifically, the plants Artemisia austriaca, Poa pratensis and Elytrigia repenswere examined for the analysis.The content and distribution of Zn and Cd, which are most distributed in industrial emissions and belong to the first class of hazardous elements, were measured. The maximum permissible content (MPC) of Zn in the raw material of Artemisia austriaca and Elytrigia repens was found, as was the maximum content of Cd in all analyzed plants growing in the 5km area around thepower station. The plant Artemisia austriacawasfound to have Zn and Cd accumulation in itsabovegroundcomponents, while in Poa pratensis and Elytrigia repens, accumulation was in the roots. The morphobiometric parameters of the plants were mostly dependent on the soil properties, followed by the degree of technogenic load. The content of Zn and Cd in the medical drugs was higher than the MPC without visible features of heavy metal pollution and so these plants weredangerous for human health.

Abstract 3-Mercaptopropyl-trimethoxysilane and [3-(2-aminoethylamino)propyl]trimethoxysilane were used to functionalize the surface of silica from Piotrowice in Poland to stabilize heavy metals (HMs) and arsenic in soil. The soil for the study was sampled from the impact zone of Głogów Copper Smelter and Refinery. The soil samples were exposed to five-step Tessier sequential extraction. The speciation studies were limited to five sequentially defined fractions in which metal content was determined. The addition of unmodified silica did not affect significantly the concentration of metals in individual fractions. Significant changes were noted upon introduction of functionalized silica in the soil. The hybrid formulations obtained significantly reduce the release of heavy metals and arsenic from soil sorption complex. The results indicate the potential use of functional formulations for reduction of metal migration in soil in the areas of exceeded concentration of heavy metals and arsenic in the soil, caused by industrial activity.

Background: The transformation of natural elements, the migration of soil substances used in industry most often refer to metals, as a result of which “metallization” of landscapes occurs in industrial regions. Methods: The article proposes an analysis of studies, conducting agroecological monitoring of soil and plants in the zone affected by the action of Ryazan power plant in 2015-2019. Experiments included the analysis of the soil and climatic conditions of the area, sampling in the zone of five rings of the pipe of the polluting enterprise, the analysis of the content of some trace elements in the coal during combustion and the products of their combustion, as well as heavy metals in the biomass of the main types of plant communities in the zone of influence and mobile forms of metals in the soil of the zone, depending on the main directions of influence. Result: According to the results, the greatest distribution of mobile forms of heavy metals in the impact zone of Ryazan State District Power Plant (RGRES) was observed in the southern and southeastern directions in radii from 2.5 km to 30 km, in the southwest direction it was in radii from 500 m to 7 km and in the northern and northwestern directions it was within a radius of 500 m to 2.5 km from the station.

The results of studies of peat located in the impact zone of municipal landfill are presented. It is established that according to the peat genetic horizons profile the distribution of the mobile fractions of heavy metals is manifested in a gradual decrease with depth. The content of heavy metals (manganese, copper, zinc, lead, cobalt, mercury) in the peat does not exceed the MAC, except for cadmium, which is spread by waste from the landfill. The source of cadmium in landfills is waste containing lacquers and paints, fluorescent lamps, batteries etc. Cadmium sulfide is the basis for yellow paints used in vehicle dyeing, textile production, soap making. Peat is characterized as very poor in micromycetes distribution. Some micromycetes detected are indicators of high mineral content and low heavy metal content. Analysis of peat micromycetes by growth rate showed that the slowest growing micromycetes owns the largest proportion - 70%. The distribution by color showed that dark-colored micromycetes of the Moniliaceae, characterized by toxicity, predominate. According to the humus reserve, peat is slightly humus. It is not recommended to use such peat for crop cultivation. Instead, peat can be a source of fuel under conditions of industrial development and compliance with existing rules and state standards.

Abstract The results of the study of the gross content of 14 chemical elements in lichen Platismatia interrupta collected around the geothermal power station “Mendeleevskaya” on Kunashir Island are presented. The highest exceedance was noted for As in the research area. The gross content of As varies from 0.8–2.6 mg/kg in control areas and up to 5–9 mg/kg in the impact zone, i.e. the maximum excess in lichen is noted by 11.6 times. For other elements, there were no strong exceedances in the impact zone compared to the control areas. According to the results of regression analysis, a statistically reliable inverse exponential relationship between the content of As and the distance to the power station (adjusted R2: 0.86, p-value: 0.001) is traced. The average value of the enrichment coefficient for As exceeds 100, which indicates the non-substrate origin of this element.

The transient multiphase flow behavior in a single-strand tundish during ladle change was studied using physical modeling. The water and silicon oil were employed to simulate the liquid steel and slag. The effect of the turbulence inhibitor on the slag entrainment and the steel exposure during ladle change were evaluated and discussed. The effect of the slag carry-over on the water-oil-air flow was also analyzed. For the original tundish, the top oil phase in the impact zone was continuously dragged into the tundish bath and opened during ladle change, forming an emulsification phenomenon. By decreasing the liquid velocities in the upper part of the impact zone, the turbulence inhibitor decreased considerably the amount of entrained slag and the steel exposure during ladle change, thereby eliminating the emulsification phenomenon. Furthermore, the use of the TI-2 effectively lowered the effect of the slag carry-over on the steel cleanliness by controlling the movement of slag droplets. The results from industrial trials indicated that the application of the TI-2 reduced considerably the number of linear inclusions caused by ladle change in hot-rolled strip coils.

Abstract Tuvalu and Nauru are isolated developing island nations located in the South Pacific Ocean. In contrast to the established larger Pacific destinations such as Fiji and Tahiti, the tourism industries on both Tuvalu and Nauru are in their infancy. Tourism development in these remote island nations faces a myriad of challenges which include a lack of infrastructure, environmental susceptibility, economic vulnerability, difficulties with access and considerable distances from major tourist markets. This paper reviews tourism on Tuvalu and Nauru and evaluates their current situation regarding potential tourism development through workshops with relevant stakeholders, surveys and subsequent SWOT analysis. The results of the paper outlined a large number of challenges faced by Tuvalu and Nauru due to their geographic location but also highlighted that both Islands possess fascinating and unique features that have the potential to attract niche tourism markets. A key finding of this paper is that the tourism stimulus or potential attraction can also be the chief threat to the islands’ economic survival hence the two edges of the sword. Further research is required to assess the effect of the withdrawal of the Refugee Processing Centre on Nauru’s economy and to evaluate the impact of climate change on Tuvalu’s society and potential adaption strategies.
