Phytochelatin synthesis in response to Hg uptake in aquatic plants near a chlor-alkali plant

The effects of mercury (Hg) released from a chlor-alkali plant factory in aquatic plants along the Ebro River basin (NE Spain) were analysed considering the phytochelatins (PCs) and their isoforms content in these plants. These compounds were analyzed using HPLC with amperometric detection, and the...
