It can contain phytotoxins that cause blistering of skin, so should be treated with caution, but it is not the same thing as Heracleum mantegazzianum (giant hogweed) which is the one with the toxic sap (and which might also likely be present in Cardiff ).
However, eutrophication is considered also as a major factor in determining reed decline, and the reed weakening by eutrophication is further forced by increased accumulation and decomposition of organic matter under anoxic conditions releasing fatal phytotoxins (Armstrong et al.
