Abstract
ABSTRACTThe accident at the Chernobyl nuclear power plant on 26 April 1986 contaminated tracts of Europe with radionuclides. In Ukraine, two million hectares with radiation levels greater than 5.55 × 1011 Bq/km2 were removed from agriculture and 137Cs, with a half-life of 30 years, is still with us. Phytoremediation by vegetation that accumulates toxic elements has been widely applied. White sweet clover (Melilotus albus) accumulates caesium and heavy metals in its biomass but, at the same time, produces nectar and pollen of a safely low level of 137Cs; so this culture is safe for beekeeping in the Chernobyl contamination zone. Growing M. albus over two years (2021–2) on a sandy sod podzolic soil within the Zhytomyr region increased the soil’s easily-hydrolysable N by 29.9%, decreased mobile phosphorus by 18.2%, and mobile forms of Cd by 38.5%, Hg by 25%, Pb by 24.5%, Cu by 18.5%, Zn by 14.9%, 137Cs by 8%.KEYWORDS: Phytoremediationsoilheavy metalsradioactive caesium Disclosure statementNo potential conflict of interest was reported by the author(s).
期刊介绍：
For more than 45 years, the International Journal of Environmental Studies has been pre-eminent in its field. The environment is understood to comprise the natural and the man-made, and their interactions; including such matters as pollution, health effects, analytical methods, political approaches, social impacts etc. Papers favouring an interdisciplinary approach are preferred, because the evidence of more than 45 years appears to be that many intellectual tools and many causes and effects are at issue in any environmental problem - and its solution. This does not mean that a single focus or a narrow view is unwelcome; provided always that the evidence is indicated and the method is robust. Pragmatic decision-making and applicable policies are subjects of interest, together with the problems in establishing facts about dynamic systems where long periods of observation and precise measurement may be difficult to secure. In other words, a systems or holistic approach to the environment and a scientific analysis are complementary, and the distinction between ’hard’ and ’soft’ science is bridged in most of the papers published. These may be on any item in the agenda of environmental science: land, water, food, conservation, population, risk analysis, energy, economics of ecological and non-ecological approaches, social advocacy of arguments for change, legal measures, implications of urbanism, energy choices, waste disposal, recycling, transport systems and other issues of mass society. There is concern also for marginal areas, under-developed societies, minorities, species loss; and indeed no element of the subject of environmental studies, seen in an international and interactive mode, is excluded.
