Antarctica Wanda salt lake water suspended solids flow: water depth 12m, 1 1 9 673mg / cm2 · a; 3 2m, 67 93mg / cm2 · a; 45m, 1582mg / cm2 · a; 48m, 946mg / cm2 · a ; 60m, 135mg / cm2 · a; 65m, 303mg / cm2 · a. The clay minerals in lake water are mainly illite with content of 64-67%, secondary chlorite, content of 25-30%, montmorillonite of 5-9-6.6% and very low content of kaolinite . Concentration of trace metals in lake water suspended solids: water depth of 12 m, Cr 5 4 3 μg / g, Cu 1 1 9 3 μg / g, Ni 5 3 4 μg / g, Co 2 39 μg / g, Cd 1 43 μg / g ; 3 2 m, Cr 44 9 μg / g, Cu 1 1 7 7 μg / g, Ni 5 0 2 μg / g, Co 1 9 4 μg / g, Cd 1 5 1 μg / Cu1 42 μg / g, Ni5 98 μg / g, Co 1 98 μg / g, Cd 1 83 μg / g; 60 m Cr1 32 μg / g Cu 49 6 μg / Co 4 3 μg / g, Cd 0 3 7 μg / g; 65 m, Cr 7 4 μg / g, Cu 1 7 6 μg / g, Ni 6 7 μg / g, Co 2 4 μg / g, Cd 0 3 6 μg / g. The content of trace metals in suspended solids is in the order of Cu> Cr> Ni> Co> Cd. At depths of more than 60 m, trace metals in suspended solids are mainly bound to silicate, manganese oxides and iron hydroxide particles. When the water depth is 60 m or less, the trace metals are mainly bound to silicate minerals and organic matter Particles.
