The ILs used in this study were obtained from the Ionic Liquid Research Centre located at Universiti Teknologi
Petronas, Perak Malaysia. The ILs which were tested on marine fish are 1-Butyl-3-Methylimidazolium hydrogen
sulphate [BMIM][HSO4] and 1-Butyl-3-Methylimidazolium bis (trifluoromethylsulfonyl) imide [BMIM][TFSI]. The
IL tested on freshwater fish, Hexyl Methylimidazoliumbis (trifluoromethylsulfonyl) imide [HMIM][NTf2] and it's
also obtained from the same research centre. The three ILs were prepared and synthesized using the Metathesis
Process.
