Petrology’s Role in Unveiling Geochemical Controls on Soil Contamination: China’s Environmental Assessment (2000-2022)

Abstract

This review explores the pivotal role of petrology in unraveling geochemical controls on soil contamination, focusing on China’s environmental assessment from 2000 to 2022. Petrology, as a cornerstone of geology, investigates rocks’ mineral composition and origin. In the context of soil contamination, it elucidates the geological factors influencing soil composition, contaminant sources, and their interactions. The paper examines the interconnectedness of petrology and geochemistry, emphasizing their symbiotic relationship in understanding soil contamination. Key sections include an overview of petrological techniques, historical context of soil contamination in China, geochemical patterns in Chinese soils, challenges, and future directions. The findings underscore petrology’s significance, offering insights into environmental policies, sustainable soil management, and recommendations for future research. The synthesis of petrological insights proves indispensable in navigating the complexities of soil contamination, fostering informed decision-making, and ensuring sustainable environmental stewardship.
