Abstract:	Tur is a river of medium size that springs from Gutâi Mountains and it flows into Tisa, in Hungary. It is polluted by the waters discharged by the neighbouring localities, by the mine waters discharged by Turţ brook and by the agricultural fertilizers, used mainly in their inferior course. Samples of water and mud were taken from many points from the river. More indicators of water and mud quality at the oxygen consumption, biogenic elements (total Hydrogen and Phosphorus) and heavy metals were analysed. The analysed water samples indicate a water of good quality, less at Zinc, and the mud samples show the accumulation of some pollutants over the admitted quota at Zinc, Titanium and Arsenic. The accumulation of heavy metals in the mud is bigger than in the water. The pollution indicator (Ip) for the Tur’s water was calculated, establishing the 9 grade of estimation which means almost natural water, but slightly affected by the anthropic impact, requiring some measures of ecological reconstruction.
