This article is devoted to the study of water and sediment pollution in the channel of the Neva delta. Spectrophotometry was used to determine the concentration of pollutants in water. In the chemical analysis of the precipitate, atomic absorption spectroscopy and infrared spectroscopy were used. Analysis of the hydrochemical composition and sediment of the Smolenka River showed high concentrations of heavy metals and petroleum products. At the same time, the hydrochemical composition of the Smolenka River is highly unstable, but the concentration of oil products and lead in the sediments indicates the presence of local pollution sources. Based on our findings, we are guided by the restoration of the aquatic environment.
The problem of drilling waste utilisation is assumed to be resolved through the implementation of the complex of environment protection measures in production engineering. They include primarily the use in the process of well drilling of drilling mud on the basis of water-soluble biodegradable polymers and a four-stage drilling mud refining system. Secondly, the usage of the well site construction with trenching for allocation of expressed bore mud and a temporary ground tank for drilling waste water.
The research is devoted to assessing the negative impact of the amber-succinite deposit in the Kaliningrad region as one of the sources of complex pollution of the Baltic Sea waters. The Baltic Sea is one of the most polluted water bodies in Europe today. There are many natural and anthropogenic factors that cause this ecological situation. Industry is one of the significant contributors to the pollution of the waters of the Baltic Sea. The industrial wastewater discharged into the Baltic Sea often does not comply with the state ecological standards. The wastewater disposal system modernization by creating a recycled water supply is one of the most effective ways to reduce the negative impact of industrial wastewater on the Baltic Sea ecosystem nowadays. This technological solution allows to significantly reduce or to completely prevent the discharge of wastewater into the Baltic Sea.
It has been noted that the areas disturbed by open-pit mining together with the production processes in the extraction of mineral resources (drilling, blasting, transportation, etc.) have a negative influence on the environment in general and the atmosphere in particular. It has been indicated that, in percentage terms, dusting of refuse dumps and tailing dumps plays a prevailing role in the total amount of dust generated. It has been stated that the processes of formation and subsequent transfer of dust in the atmosphere depend on the combination of meteorological and mining factors that have a probabilistic nature in time and space. It has been shown that the maximum value of environmental risk characterises the level of dust influence, at which reduction environmental protection measures should be directed. The present paper proposes a procedure for evaluation of the dusty influence of mining enterprises on the environment. Under the conditions of Olenegorsk GOK, a GIS has been compiled – a project of the study area and, based on geo-information modelling, the results of calculating dust concentrations in the air have been imposed on a digital map of the area.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
