溶解有机碳（DOC）对金属的生物有效性有很大影响。废水处理流出物将相当数量的DOC和金属添加到接收沃茨，并且随着流出物控制变得更加严格，可能需要先进的流出物处理。我们评估了两种类型的深度处理工艺对废水中金属可用性的影响。微量金属的可用性进行了评估，使用扩散梯度薄膜和预测通过形态建模。结果表明，深度处理后的金属有效性差异不大。EDTA类化合物是废水中重要的金属络合剂。
The bioavailability of metals can be strongly influenced by dissolved organic carbon (DOC). Wastewater treatment effluents add considerable quantities of DOC and metals to receiving waters, and as effluent controls become more stringent advanced effluent treatments may be needed. We assessed the effects of two types of advanced treatment processes on metal availability in wastewater effluents. Trace metal availability was assessed using diffuse gradients in thin films and predicted through speciation modelling. The results show little difference in metal availability post-advanced treatment. EDTA-like compounds are important metal complexants in the effluents.
