Abstract

- Embryo development of sediment-dwelling amphipod Monoporeia affinis is sensitive to contaminant exposure. Therefore, embryo aberrations in gravid females are used to detect the biological effects of contaminant exposure in the Baltic Sea benthic habitats. The indicator based on the aberration frequencies in wild populations (ReproIND) is currently used for environmental status assessment within the Marine Strategy Framework Directive, Descriptor 8.2. However, so far, it has mainly been applied in the Bothnian Sea (BoS) and the Western Gotland Basin (WGB), where it was found to respond to contaminant pressure and non-chemical environmental factors, such as temperature. To expand the applicability of the indicator to other Baltic Sea basins, we used field data from the gulfs of Finland and Riga, BoS, and WGB to investigate the relationships between reproductive disorders and contaminants and environmental factors, thus evaluating the indicator suitability in these areas. Despite the natural variability of the environments and contaminant distribution across and within the basins, we found that high concentrations of contaminants, e.g. metals, PAHs, and PCBs, contribute significantly to the embryo aberrations in M. affinis. These findings support ReproIND applicability in the Baltic Sea and, perhaps, in other marine areas.
