  • Assessing Soil Quality of Pb‐Zn Smelting Sites by a Two‐Step MDS ‐Based Model

    Open AccessLiyuan Ma, Chun Li et al.ARTICLELand Degradation and Development2025

    Heavy metals (HMs) emitted from the smelting process accumulate in soil, reducing soil quality and subsequently affecting human health. Estimating the extent of land degradation and analyzing the limiting factors of soil quality are essential to facilitate soil management and ecological restoration at smelting sites. This study aims to select the most effective indicators to construct a streamlined minimum data set (MDS) for soils of Pb‐Zn smelti…

    Objectives. We sought to compare the burden of hospitalizations associated with rotavirus gastroenteritis (RGE) in children younger than 5 years in US Medicaid and non-Medicaid populations in 2000 and 2003. Methods. We used the Kids' Inpatient Database (KID) to examine the burden of RGE-associated hospitalizations in terms of numbers and rates of hospitalizations, lengths of stay, and hospital charges. Two indirect methods were also used to estim…
