Transfer and distribution of 1,2,4-TCB in water and Hydrocotyle vulgaris L. of simulated micro-cosmos system

The paper studied the transfer and distribution of 1,2,4-TCB in water and Hydrocotyle vulgaris L. of simulated micro-cosmos system.The results showed that 66.7% of 1, 2, 4 -TCB volatilized to atmosphere in ten days, and the rest was transferred to different organisms.The residual 1,2,4-TCB in water remains relatively stable, nonbiodegradable. Some of them were transfered to H. vulgaris L.The process of transfer was a physical adsorption process. The content of 1,2,4-TCB reached the highest value in 10 days, then decreased gradually. The contents of 1,2,4-TCB in H. vulgaris L. reached balance in 15 days.
