How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Heavy metals refer to special pollutants, monitoring of which is obligatory in all environments. In this regard, the study of soil contamination with heavy metals is one of the urgent issues. The research results showed that the amount of heavy metals in samples from sites located along the Tashkent tract was several times higher than the norm. The study of anthropogenic impact on soil microbiota is a necessary element of any biomonitoring study. Heavy metals already rank second in terms of danger, inferior to pesticides and well ahead of such well-known pollutants as carbon dioxide and sulfur. In the future, they may become more dangerous than nuclear power plant waste and solid waste. Contamination with heavy metals is associated with their widespread use in industrial production. Due to imperfect cleaning systems, heavy metals get into the environment, including soil, polluting and poisoning it.
