Detection of heavy metals and pesticides in the raw materials of Araxacum Officinale Wigg and Taraxacum Kok-saghyz Rodin plants

Abstract

Taraxacum officinale Wigg and the results of scientific research on the development of modern methods of physicochemical analysis of heavy metals that can be found in raw materials of Taraxacum kok-saghyz Rodin, and the presence of pesticides in plants using the GOST (governmental standard) European Pharmacopoeia standard. Methods for the quantitative determination of inductively coupled plasma mass spectrometry (ICP-MS) of heavy metals; macro and microelements in plant raw materials have been developed. The test for the presence of pesticides and heavy metals in plants according to the GOST standard of the European Pharmacopoeia was carried out in accordance with the Sanitary Rules and Standards of the Republic of Uzbekistan.

Study on the Aral Sea crisis from the risk assessment of polycyclic aromatic hydrocarbons and organochlorine pesticides in surface water of Amu Darya river basin in Uzbekistan

“…The other OCPs, such as heptachlor and methoxychlor were uncommon, and these findings were consistent with the OCPs detected in the water in this study, where OCPs residues in food may have resulted from contact with contaminated water or soil (Muntean et al, 2003;Herbst et al, 2008;Snow et al, 2020). Particularly in the case of the Aral Sea, where the riverbed was constantly absorbing saline substances from the watershed and pesticides and herbicides from agricultural drainage water, the dry riverbed, which was expanding yearly, had become an essential source of local dust and salt aerosols, and pollutants were deposited over large areas through atmospheric transport (Lozowicka et al, 2015;Burr et al, 2019;Yuldasheva et al, 2021).…”

Investigating the urban land pollution level according to the bioindicator properties of plants

“…The existence of a correlation between the environment and the content of heavy metals in plants determines the use of plants as indicators of natural and anthropogenic landscapes. The existence of a relationship between the amount of heavy metals in the environment and plants determines their use as indicators of pollution of natural and anthropogenic landscapes [2][3][4][5].…”
