Biogeochemical and engineered barriers for preventing spread of contaminants

Abstract

The intensive industrial development and urbanization, as well as the negligible return of hazardous components to the deeper layers of the Earth, increases the contamination load on the noosphere (i.e., the new status of the biosphere, the development of which is mainly controlled by the conscious activity of a human being). The need for reducing the spread and mobility of contaminants is growing. The insights into the role of the tree in the reduction of contaminant mobility through its life cycle are presented to show an important function performed by the living matter and its products in reducing contamination. For maintaining the sustainable development, natural materials are often used as the media in the environmental protection technologies. However, due to increasing contamination intensity, the capacity of natural materials is not sufficiently high. Therefore, the popularity of engineered materials, such as biochar which is the thermochemically modified lignocellulosic product, is growing. The new approaches, based on using the contaminant footprint, as well as natural (biogeochemical) and engineered barriers for reducing contaminant migration and their application, are described in the paper.

Circular Economy Benefit Indicators for Using Biochar in Regenerative Agriculture

“…The contaminant footprint indicator pertains to the contaminant density in the environment, the amount of which is in uenced by the increased amount of extracted resources from the Earth.. The environmental self-puri cation capacity starts to decline as far as the contamination footprint in the biosphere increases (Baltrėnaitė et al 2018). In the boundaries of agriculture, it encompasses the contaminants (such as potentially toxic elements, including Zn, Ni, Cu, Cr) entering the agricultural system with fertilizers and amendments (e.g.…”

“…Возможно создание искусственных геохимических барьеров. Среди направлений их использования, кроме очистки природных и сточных вод от тяжелых металлов, радиоактивных элементов и нефтепродуктов, могут быть выделены [Максимович, 2010;Chanturiya et al, 2014;Baltrėnaitė et al, 2018]:…”

Utilizing sustainable hemp biomass as an eco-friendly for potentially toxic elements removal from water

“…The extraction of PTEs globally has increased by over 75% over 35 years [7]. It is known that PTEs such as Copper, Zinc, Lead, and Nickel are produced more than 1000 m 3 tons per year, and accordingly, their consumption values increase in this context [7,8]. As a result of increased exposure to PTEs, they affect human health negatively by penetrating into water resources [9].…”
