Titanium dioxide as a pollutant

Titanium dioxide is used as a pigment in paints. The production procedure is highly polluting because of the large quantities of wastes which are often thrown into the sea where, by chemical reaction, they can be transformed into 'red mud'. These wastes destroy living organisms such as plankton and they can also impregnate the flesh of fish used for human consumption.
