The research was conducted on two rivers in Western Pomerania: the Parsęta and the Radew. Both rivers flow in close vicinity of the Oil and Natural Gas Field in the village of Krzywopłoty, on the outskirts of Karlino. Rivers in the area near the Baltic Sea in Poland typically carry products of agricultural and household origin. Only occasionally, there are also point-like pollution sources of industrial origin. Pollutants from these sources, among which heavy metals are noted, accumulate in aquatic plants which grow in the river beds. The objective of the research was to evaluate the effect of a petroleum mine on the quality of the aquatic environment and aquatic plants in the Radew and Parsęta rivers based on the determination of metal bioaccumulation in plants. The analytical material (water and plants) was collected in the summer of 2012 and 2013, from 9 sites on each river. The content of Cu, Ni, Cd, Pb and Zn was determined with atomic absorption spectrophotometry. Analysis of the metal content in aquatic plants growing along the course of a river gives good representation of the metal distribution and can also be used to reflect the actual effect of point-like pollution sources on the aquatic environment. Results of an investigation into the effect of natural gas and oil field operations on metal bioaccumulation in aquatic plants of rivers in Western Pomerania are presented in this paper. The content of metals in river water was low and can be ordered as follows: Cd-3), Cd (0.001-0.013 mg Cd dm-3), Pb (0.075-0.113 mg Pb dm-3), Zn (0.010-0.066 mg Zn dm-3 and Cu (0.003-0.040 mg Cu dm-3). Heavy metal levels in aquatic plants were relatively low. The content of metals in aquatic plants was the following: Ni (1.61-27.48 mg Ni kg-1), Cd (0.52-6.96 mg Cd kg-1), Pb (7.45-60.15 mg Pb kg-1), Zn (13.09-125.63 mg Zn kg-1) and Cu (1.54-36.97 mg Cu kg-1). The levels of these metals in water and plants in both rivers can be ordered as follows: Cd
