Tyne, river

The presence of plumboferrite [ PbFe407] in the Tyne River sediments was reported by Hudson-Edwards et al. (1996), and the mineral has also been identified as a secondary product in tailings (Morin et al., 1999). Although aluminum hydroxides play a prominent role in geochemical modeling, few occurrences of such material have...

In 1994, researchers put cages of male rainbow trout into five rivers. In each case five sites were chosen, one upstream of a waste treatment plant, one at the point where the effluent was discharged, and three others at various distances downstream. It was found that the female protein vitellogenin was produced in male fish in four out of the five rivers at the site of the effluent discharge. The other waste treatment plant did not receive industrial waste. In one river, where the effluent was the most active, at all the other sites, up to 5 km downstream, the fish produced vitellogenin. It has also been found that male fish such as flounder in estuaries in the UK also have high levels of vitellogenin. In the Tyne and Mersey estuaries the increased levels of the female protein were 10,000 to i million times more than in control animals.
