Portable X-ray fluorescence (pXRF) is one of the main geochemical techniques employed in multi-elemental analysis screening for contaminated sites management. As confidence pXRF analyses are matrix-specific, efforts made to provide studies quality on different datasets, focusing less investigated elements such as mercury (Hg) and antimony (Sb), help both new experienced users. The environmental solid samples from two decommissioned mining NE Italy, characterised by Pb-Zn (Hg-rich) Cu-Sb ore deposits, were prepared with protocols compared traditional destructive analyses. Sample composition was found strictly dependent occurrence false positives overestimation at low concentrations. In contrast, milling sample did not produce major variations overall quality. Lead (Pb), Sb, Zn reached definitive data least datasets. Consequently, far a thorough QA/QC protocol followed, can rapidly chemical that accurate produced standard laboratory techniques, thus allowing identify potential sources contamination could be reprocessed extraction valuable mitigating dispersion contaminants ecological or health risks.

This study investigates the contribution of river morphology towards occurrence manganese (Mn) in both sediment and surface water (SW), considering temporal climatic spatial conditions. The Boac Mogpog rivers on island province Marinduque, Philippines, were examined this study. These are downstream two abandoned open mine pits at San Antonio Tapian, where mining disasters occurred 1993 1996, respectively. Field sampling programs conducted 2019, 2021 2022 to measure Mn concentrations SW, physicochemical parameters SW during same event. Geographic Information System (GIS) tools employed characterize each river, specifically slope, bends, sinuosity, channel width length. divided into 22 15 segments, respectively, account for heterogeneity all parameters. Correlation (r) analysis average concentration within segment was performed indicated that bends (Boac r = 0.421, 0.356) sinuosity 0.403, 0.352) had highest correlation with sediment. While slope 0.716, 0.282) 0.505, 0.257) SW. confirmed planform affected accumulation due its effect deposition along potential adsorb and/or desorb metals. Furthermore, pH also directly correlated (r 0.293), inversely −0.465), which expected as acidic promotes release metals from sediments results will aid local government, environmental engineers managers their mitigation program through identification areas segments contain least contamination. is optimize financial human resources system remediation monitoring. Data information extracted useful other similar condition.
