Rezumat

The river Bic waters have been in a catastrophic condition during recent decades, as confirmed by data of different environmental expeditions, the last of which took place in July 2013. During that expedition, 25 young people covered in one week the distance from the place where the river starts up at the mouth of the estuary, in order to assess the pollution level. The expedition was funded by the US Embassy in Moldova. According to the data obtained during that expedition, and in accordance with previously gathered data, it was acknowledged that the waters that exit from Chisinau were dead and didn’t contain any life forms and water pollution exceeded the permissible level dozens of times. Published scientific data indicate the pollution level of the river Bic, but few studies are carried out on water pollution with heavy metals. On the basis of previous data, it was decided to collect samples from three points of river Bic: upstream Straseni region, the region of Tobacco CTC in Chisinau and upstream of village Bic. Collected water samples were analyzed using AAS and ICP-MS methods. In collaboration with colleagues from Cluj Napoca, Romania under a bilateral project, seven heavy metals were analyzed: Cr, Mn, Ni, Cu, Zn, Cd, Pb. Of the seven examined heavy metals, Pb and Cd were not detected, while the highest detected amount was that of Mn which ranged between 115-800 mg/L in all three points. The remaining heavy metals were present in smaller amounts. Further, seasonal collection of water samples from the river Bic is planned and their analysis for heavy metal content.
