Data confidence 70 medium

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

Soil contamination associated with solid household waste landfills represents a significant environmental concern because heavy metals can accumulate in surface horizons and migrate into adjacent ecosystems. This study aimed to assess the level and spatial distribution of heavy metal contamination in soils surrounding the solid household waste landfill adjacent to the Shchuchinsk-Borovskaya resort area, Kazakhstan. In August 2024, 12 composite soil samples were collected from the 0–20 cm layer i
