By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News-New research on Nanotechnology - Nanoparticles is the subject of a report. According to news reporting from Fuzhou, People's Repu blic of China, by NewsRx journalists, research stated, "Globally extensive resea rch into how silver nanoparticles (AgNPs) affect enzyme activity in soils with d iffering properties has been limited by cost-prohibitive sampling. In this study , customized machine learning (ML) was used to extract data patterns from comple x research, with a hit rate of Random Forest > Multiple Imputation by Chained Equations > Decision Tree > K-Nearest Neighbors." The news correspondents obtained a quote from the research from Fujian Normal Un iversity, "Results showed that soil properties played a pivotal role in determin ing AgNPs' effect on soil enzymes, with the order being pH > organic matter (OM) > soil texture cation exchange capa city (CEC). Notably, soil enzyme activity was more sensitive to AgNPs in acidic soil (pH <5.5), while elevated OM content (> 1.9 %) attenuated AgNPs toxicity. Compared to soil acidification, r educing soil OM content is more detrimental in exacerbating AgNPs' toxicity and it emerged that clay particles were deemed effective in curbing their toxicity. Meanwhile sand particles played a very different role, and a sandy soil sample a t > 40 % of the water holding capacity (WH C), amplified the toxicity of AgNPs. Perturbation mapping of how soil texture al ters enzyme activity under AgNPs exposure was generated, where soils with sand ( 45-65 %), silt (<22 %), and clay (35-55 %) exhibited even higher probability of positive effects of AgNPs. The average calculation results indicate the sandy clay loam (75.6 % ), clay (74.8 %), silt clay (65.8 %), and sandy clay ( 55.9 %) texture soil demonstrate less AgNPs inhibition effect."
