摘要: Abstract Marine cross-border areas are ideal for monitoring pollutants so as to increase ecosystems protection. This study was conducted at the Romanian-Ukraine border of Black Sea reveal evidence contamination with toxic metals based on biomonitoring of: cadmium, lead, total chromium, nickel and copper different water depths prey-predator interactions, combined environmental forensics techniques biological sampling separation in witnesses size groups. The species used were Mytilus galloprovincialis L. Rapana venosa V. collected 17.5 m, 28 m 35 m depth. An atomic absorption spectrometer a high-resolution continuum source graphite furnace quantification various samples: sediments, soft tissue, stomach content, muscular leg, hepatopancreas. best sample type, pathology metal location bioaccumulation, is hepatopancreas from R. that proved significant decrease cadmium lead lower depths.
