Thiencarbazone-methyl, a triazole herbicide was assessed for its environmental fate by carefully imitating and analyzing the natural pedosphere through diverse experiments involving adsorption, desorption, hydrolysis, photo-degradation and degradation in ten distinct soils. Sorption experiments were performed through batch equilibrium method. Soils’ physicochemical properties highly influenced the sorption of the herbicide. Results were characteristic of an overall weaker physisorption and an exothermic response reflected by means of negative qualities for Gibbs free energy. Hydrolytic, photolytic and soil degradation experiments were performed for thiencarbazone-methyl for determination of the impact of biotic and abiotic parameters on its degradation. UV–Vis spectrophotometer and GC–MS was utilized for the investigation of thiencarbazone-methyl-treated soils after extraction at regular intervals. The adsorption co-efficient value ranged from 4.3 to 26.4 µgml⁻¹. Minimum half-life in hydrolysis, photo-degradation and soil degradation experiments was 18, 18.7 and 16 days, respectively; while, the highest was 22, 22.6 and 23.9 days, respectively. Results depict moderate binding and low persistence of thiencarbazone-methyl to the selected soils whilst being highly susceptible to transformative pathways.

通过在包括十种不同土壤中的吸附，解吸，水解，光降解和降解在内的各种实验中仔细模拟和分析了天然双足层，评估了三唑类除草剂噻菌灵甲基的环境命运。通过间歇平衡法进行吸附实验。土壤的物理化学性质极大地影响了除草剂的吸附。结果的特征是总体上较弱的物理吸收和通过吉布斯自由能的负质量反映的放热反应。进行了噻菌灵甲基的水解，光解和土壤降解实验，以确定生物和非生物参数对其降解的影响。定期萃取后，利用紫外可见分光光度计和气相色谱-质谱仪对噻菌灵处理的土壤进行了研究。吸附系数值范围为4.3至26.4 µgml^-1。水解，光降解和土壤降解实验的最小半衰期分别为18天，18.7天和16天。最高分别为22、22.6和23.9天。结果表明，噻菌灵zone甲基与选定土壤具有中等结合力和低持久性，同时极易受到转化途径的影响。
