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 with oil products remains a pressing environmental issue, particularly in regions with extensive oil production. Promising approaches to remediating such soils include the use of humic substances, which bind pollutants and promote microbiological degradation. This study aimed to evaluate the effectiveness of oil-contaminated soil remediation using basic potassium humate and its modified forms at concentrations of 1% and 10% over a 60-day experimental period. Oil-contaminated s
