Article Synopsis
- - The study examined how different concentrations of antimony (Sb) impact barley root growth across 21 varying Chinese soils after being aged for 3 months.
- - Results showed significant variability in Sb toxicity levels, influenced by soil properties, with bioavailable Sb concentrations ranging from 2.08% to 11.94% of total Sb in the soils tested.
- - Key soil factors, particularly the sand fraction, were found to increase Sb bioavailability, and the research aims to help set regulatory standards for Sb levels in agricultural practices.
Arsenic (As) and antimony (Sb) are considered as priority environmental pollutants and their accumulation in crop plants particularly in rice has posed a great health risk. This study endeavored to investigate As and Sb contents in paired soil-rice samples obtained from Xikuangshan, the world largest active Sb mining region, situated in China, and to investigate As speciation and location in rice grains. The soil and rice samples were analyzed by coupling the wet chemistry, laser ablation-inductively coupled plasma mass spectrometry (LA-ICP-MS), synchrotron-based micro X-ray fluorescence mapping (μ-XRF) and micro X-ray absorption near-edge structure (μ-XANES) spectroscopy.
