Accumulation of Heavy Metals in Different Bodies of Dandelion (Taraxacum Officinale Wigg)

Abstract

AbstractIn this paper, the process of accumulation of heavy metals in various organs of the Taraxacum officinale plant, which is widespread in urban areas, was studied. The amount of chemicals in the samples taken from the various organs of the plant will largely depend on how far or close the city highway is to the accumulation of heavy metals in the organs of the plants. The content of 17 heavy metals in the plant was determined. It has been stated that the Taraxacum officinale plant can be used as a bioindicator in the detection of environmental pollution. The accumulation of the most dangerous elements in the leafy part of the plant along the Tashkent city highway (Uzbekistan) is greater than in the flower. As a result of analysis of environmental pollution by taking samples from plant growth along the Tashkent highway and at a distance of 50 m, 100 m, 200 m, and 350 m from the road, the leaves and flowers of the plant are indicators of surface pollution, while the root part is the most dangerous heavy soil. The calculation of indicators of contamination with metals was determined.KeywordsAgriculture industryDandelionHeavy metalsAnthropogenic factors
