The potential environmental distribution of MADAME obtained from a generic level III fugacity model under two emission scenarios is shown in the tables. 

The results show that if MADAME is released into air, it mainly remains in the soil. If the substance is released into water, it mainly remains in water. The substance does not significantly partition to sediment.
