It is used for paints, paper, plastics, cosmetics and many other products as well. The waste products from Tioxide are solid ore which is unused , liquids containing sulphuric acid and ferrous sulphate which are dumped into the estuary. It affects our area because when it is discharged into the Humber it produces a plume of polluted water which is 20 to 40 metres wide and 1km long when tidal flows are at a maximum. Evidence shows four main parts of this discharge are acid, ferrous compounds, suspended matter and trace elements. One effect is red staining of the river banks the effect on the biology of the river is debateable some experts claim that the river is less polluted than many other estuaries others disagree with this. The Rivers Ouse and Trent contribute an average daily flow of 246 cumecs to the Humber of which about 14 cumecs are sewage effluent and 12 cumecs are trade effluent. A further 2.5 cumecs sewage and 3.1 cumecs trade effluent are discharged directly into the Humber. |
