Abstract:

In the Cretaceous paleoceanic deposits of Eastern Kamchatka, carbonaceous beds have been studied, the origin of which relates to the oceanic anoxic events. In carbonaceous rocks, the contents of trace elements and noble metals: Ba, Cu, Ni, Zn, Mo, V, U, Y, Au, rare-earth elements and platinoids are increased in comparison with the hosted jaspers and limestones. In particular, the Au content in ash-laden carbonaceous rocks reaches 0.8 ppm, and Pt 2.1 ppm. The geochemical proxies Mo/Mn and V/(V + Ni) indicate the accumulation of carbonaceous deposits in euxinic conditions. The significant non-li

We have proposed liquid feed additives, which are solutions of substances that can react with each other to form complex compounds of different composition. The dynamic equilibrium is established in the solution. If the pH changes and one complex compound decomposes, a new one is formed immediately. As a result, the trace element metal ions are chelated at a very wide range of pH values. The effectiveness of the use of solutions of chelated complex compounds and solutions of inorganic salts of copper, zinc, iron, cobalt and manganese was compared.

We quantified the soluble fractions of the soil organic carbon (SOC) concentrations and the total and water-soluble trace elements in soils contaminated by household waste and remediated via the addition of green manure over 13 years and identified the main factors controlling the vertical distribution and accumulation of the trace elements. Green manure favoured the active formation of soil organic matter. The SOC of the examined soils was characterised by the active stabilisation by mineral soil compounds, but by a low degree of humification. The soils showed increased concentrations of Cr a

Abstract:

Fast consumption, increasing energy needs, unplanned urbanization, and unconscious discharge of industrial wastes cause pollution of air, soil, food and water resources. Among these pollutants, heavy metals and metalloids are not biodegradable and accumulate in compartments such as water, soil and plants, threatening human and environmental health. Monitoring studies show that heavy metals such as arsenic, lead, mercury, cadmium, nickel, zinc, copper, chromium and trace elements are in first place according to their availability in the environment. Preventive and remedial measures should be taken to reduce the effects of heavy metals. Legal regulations, monitoring studies, the use of soluble and non-toxic compounds in environmental compartments (air, water, soil and plants) in industrial processes, heavy metal-free pesticides, appropriate wastewater treatment plants and use of renewable energy sources instead of fossil fuels are among the priority measures to reduce concentrations of heavy metals in the environment. As a bioremediation approach, removing toxic wastes from the environment by using bioaccumulatory organisms such as plants or mussels maintains its importance among studies aimed at recovery. Studies have shown that integrated methods - especially the combination of suitable plants and microorganisms - are very effective in mitigating the effect of heavy metals in the environment.

Abstract:

Донные отложения являются адсорбентом загрязняющих веществ, в частности микроэлементов, и могут содержать их в количествах, значительно превышающих предельно-допустимые концентрации. Распределение и миграция металлов контролируются в основном характером взаимодействия донных отложений, водной массы и биоты при этом возникает опасность вторичного загрязнения при взмучивании и десорбции в результате изменения физико-химических условий в системе вода-дно . Рассмотрены особенности содержания, миграции и трансформации меди (Cu) и цинка (Zn) в системе водадонные отложения . Выбор обусловлен следующим: Cu относится к высокому классу опасности, при этом отличается высокой химической и биологической активностью, а Zn отличается высоким содержанием в различных экосистемах. Соединения данных элементов не подвергаются деструкции в природных водах, а лишь изменяют формы существование в них, что приводит к изменению их миграционной способности, токсических свойств, доступности для гидробионтов и их экологической роли в водных объектах.Sediments are the adsorbent of contaminants, in particular trace elements, and can contain them in quantities well above the maximum allowable concentrations. The distribution and migration of metals are controlled mainly by the interaction of sediments, water mass and biota andthere is a risk of secondary contamination during torture and desorption as a result of changes in physical and chemical conditions water-bottom system. The specifics of copper content, migration and transformation copper (Cu) and zinc (Zn) in the water-sediment system are considered. The choice is based on the following: Cu belongs to a high danger class, with high chemical and biological activity, and Zn is high in different ecosystems. The compounds of these elements are not subject to destruction in natural waters, but only change the forms of existence in them, which leads to a change in their migration ability, toxic properties, accessibility for hydrobionts and their ecological role in water facilities.

Abstract:

In a recent report, the U.S. Environmental Protection Agency (EPA) has concluded that, with the possible exception of mercury, there is no compelling evidence that emissions from U.S. based coal-burning electric utility generators cause human health problems (EPA 1998). However, worldwide, the use of poor quality coal and/or the improper use of coal may cause or contribute to significant widespread human health problems. Health problems caused by impurities in coal, such as arsenic and fluorine, have been reported from the former Czechoslovakia (Bencko 1997) and from China. The World Bank (1992) estimates that between 400 and 700 million women and children are exposed to severe air pollution, generally from cooking fires. A substantial proportion of these people rely on coal for domestic cooking and heating and are thereby exposed to particulates, metal ions, gases (such as SOx), and organic compounds causing potentially serious respiratory problems and toxic reactions. Although addressing human health problems is the domain of biomedical and public health scientists, geoscientists have tools, skills, databases, and perspectives that may help the medical community address environmental health problems. Geoscientists are best equipped to characterize natural resources such as rocks, soils, and water. Various analytical tools used to characterize these natural materials have also been used effectively to characterize materials such as ambient dust and the products of coal combustion that cause or contribute to human health problems. In this chapter, we describe some of the geologic and geochemical tools being used to address arsenism and fluorosis caused by residential coal combustion in Guizhou Province, China. Wood had long been the primary energy source in southwest China, but by the early part of the twentieth century the forests were largely denuded and the residents were forced to use alternate sources of fuel. In southwest Guizhou Province, surface exposures of coal are plentiful and coal quickly became the primary fuel for domestic use. Unfortunately, some of these coals have undergone mineralization, causing their enrichment in potentially toxic trace elements such as arsenic, fluorine, mercury, antimony (Sb), and thallium (Tl). Burning the mineralized coals in unvented stoves volatilizes toxic elements and exposes the local population to these emissions.
