Bio-Ba/Ti, bio-Ba /Al were chosen as the sensitive markers to show the variation of the biogenic/terrigenous suspended particles in MNLS through the correlation analysis of 12 major elements of the suspended particles. Comparing with the overlain waters, the content of terrigenous particles in the BNL was increased significantly, but was lower than that in the surface sediment.

与上覆水体相比，近底雾状层内陆源组分显著增加，但较底质沉积物为低；生源组分则明显降低，但比底质沉积物为高，这一规律说明底质沉积物再悬浮对近底雾状层有显著的影响，表明Ba_/Ti和Ba_/Al值可以作为近底雾状层颗粒物的高精度示踪指标，其中Ba_/Al值尤为敏感。
