Figure 1From: Retention and mitigation of metals in sediment, soil, water, and plant of a newly constructed root-channel wetland (China) from slightly polluted source waterLocation map of constructed root-channel wetlands (CRCWs) and sampling sites in the pilot wetland. CRCWs are located in the center of Yangtze River delta on China’s southeast coast (top left), and CRCWs 1, 2 in Jiaxing City, CRCWs 3, 4 in Haining City (top right). Sediments from ponds and ditches, soils from plant beds, water, and plant above ground portion were sampled in a pilot-scale wetland of CRCW 3 (down).Back to article page
