Our purpose was to monitor the environmental pollution with heavy metals, such as Pb, Zn, Cu, and Cd, and their accumulation in Roman snails (Helix pomatia L.) and the possibility of Roman using snail as a bioindicator of heavy metal pollution. For analyses, we were taken 22 specimens of roman snails in the Mitrovica town (area with the heavy metal pollution derived from the "Trepça" smelter) and 22 specimens in the Vernica village (control area), in which case is analyzed the concentration of heavy metals: Lead (Pb), cadmium (Cd), Zinc (Zn) and Copper (Cu) in the hepatopancreas, foot, and shell of snails. Our results show the high concentration of Pb, Zn, and Cd in the hepatopancreas compared to the other tissues (foot and shell), whereas Cu concentration was higher in the foot of snails from Mitrovica compared to the control group in a significant degree (P < 0.001). We have found a significant (P<0.001) positive correlation between all heavy metals (Pb/Cd; Pb/Cu; Pb/Zn; Cd/Cu; Cd/Zn and Cu/Zn) in the hepatopancreas tissue. In the foot, we have found the negative correlation for Pb/Cd and Pb/Cu and positive for the Pb/Zn; Cd/Cu; Cd/Zn, and Cu/Zn, whereas in the shell the correlation was positive for the Pb/Cd; Pb/Cu and Cd/Cu, and negative for the Pb/Zn; Cd/Zn and Cu/Zn. In the hepatopancreas, the concentration of metals ranged from higher to the lower concentration was: Zn>Cd>Pb>Cu; in the foot: Cu>Zn>Cd>Pb, whereas in the shell: Zn>Cu>Pb>Cd. The Mitrovica town is the area with heavy metals pollution, whereas the Roman snail accumulates relatively high values of these heavy metals and can serve as an indicator organism for pollution with the metals such as Pb, Cd, Zn, and Cu.

During the study on the assessment of ecological status of the Lepenci river basin, epilithic diatoms were used. Via this methodology, the authors aimed to standardization the ecological assessment methodology and gradually make it applicable for all river basins of Kosovo. The authors relied on a hypothesis that the epilithic diatom communities can serve as a reliable ecological tool to evaluate the quality of flowing waters in Kosovo. Thirteen water quality indices (IBD, IPS, IDG, DESCY, SLA, IDSE, IDAP, EPID, CEE, WAT, TDI, IDP and SHE) were measured in eight sample-points. From the conducted qualitative analysis, the obtained results showed that the water quality varies from upper parts of the basin (SP1, SP2, SP3 & SP4) characterized with higher water quality towards the lower parts (SP5, SP6 & SP7) where water quality was of the 2nd class and finally in Hani i Elezit (SP8) where the index values showed that its water belongs to the 3rd class. The samples were taken in to 8 sampling sites, in river during year (2017), the Navicula viridula species was the most dominant, along with Cocconeis placentula var. lineate and Diatoma vulgaris. In turn, between August and end of September, the following species were dominant ones: Craticula ambigua, Navicula hintzii, Navicula viridula and Rhoicosphenia abbreviata.
