In this study, the possibility of application of agricultural lignocellulosic waste materials as adsorbents of different heavy metals ions from water was investigated. As adsorbents, wastes of widely cultivated plant cultures in our country were used. They were wheat straw, cornstalk, corn cob and soybean straw. These materials were showed as good adsorbents in most cases. But, leaching of organic matters from them during adsorption was observed. It was unfavourable. Because of that, adsorbents washed and dried. After that leaching of organic matters was significantly decreased, but also adsorption efficiencies slightly decreased, too.

One-year monitoring program was organized with the aim to assess the quality of sediment and water in these Vojvodina watercourses: the Begej, the Sava, the Botos, the Tisza, the Tamis, the Danube and the Danube-Tisza-Danube (DTD) Canal regarding metal content (Cr, Cd, Cu, Ni, Pb, Zn, Hg) in them. Water was the 1st/2nd class by MPL of national requirements, except occasionally for the copper concentration on some locations. The highest concentrations of zinc, cadmium, chromium, copper and mercury were detected in the Begej sediment. Maximum nickel concentration was in the Sava sediment, and for lead in the Danube sediment.
