Core Viewpoint - The research reveals a dual regulatory mechanism of shrimp shell biochar on arsenic migration in acidic and alkaline soils, providing a new pathway for precise arsenic pollution remediation in agricultural environments [1][2]. Group 1: Research Findings - The study published in the journal "Biochar" highlights that shrimp shell biochar significantly activates arsenic migration in acidic soils while promoting arsenic fixation in alkaline soils [1]. - In acidic environments, shrimp shell biochar enhances the solubility of organic matter, leading to increased arsenic release, and activates microbial functions that elevate the abundance of arsenic-reducing and efflux genes [1][2]. - Quantitative data indicates that arsenic migration rates in acidic soils increase by 21%-31% with biochar addition, while arsenic fixation rates in alkaline soils improve by 19%-24%, confirming the dual regulatory effect [2]. Group 2: Practical Implications - The findings challenge the traditional view of biochar's single remediation function, establishing a theoretical basis for its differentiated application in arsenic-contaminated soils [2]. - The research suggests that biochar application should be carefully evaluated based on soil pH; it should be used cautiously in acidic soils and fully leveraged in alkaline soils for stabilization [2]. - This technology represents an innovative approach to utilizing waste shrimp shells for environmental remediation, combining ecological and economic benefits, and offers a controllable solution for arsenic pollution risk management in China [2].
