water soluble matter

The excreta of humans and land animals contain soluble refractory organic matter. After countless generations in water, some of them took the risk to ascend and started the lengthy evolutionary process of terrestrial animals.

人和陆生动物排泄物含有可溶的难处理有机物质。它们在水里生活了无数时代后，才冒险登陆，开展了陆生动物悠长缓慢的演化历程。

Water-soluble organic matter in different lakes is mainly derived from biological sources. The fulvic acid and humic acid component in Chao Lake and Tai Lake are close to the land-side sources. Baiyang Lake and Lugu Lake are more inclined to the biological source. 3.

不同湖泊水溶性有机质都主要源于生物来源，巢湖和太湖富里酸和胡敏酸组分来源接近陆地端源，而白洋淀和泸沽湖更倾向于生物来源。

All the content of soluble speciation of arsenic in water is very low, the content of arsenic in free subsiding water is much higher. So the arsenic in free subsiding water is actually this in suspended solid matter.

水体中溶解态砷含量均较低，自然沉降水样中砷含量较高，故自然沉降水中砷实际上是水中悬浮性固体所含的砷，而黄河水中泥沙含量与砷含量呈紧密正相关。
