Mediterranean mussels (Mytilus galloprovincialis) were exposed over 21 days to polyethylene (PE) particles (0.01 mg ml-1; 50-570 μm) isolated from toothpaste. PE was deployed in the Outer Oslofjord (Norway) for days, before exposing both virgin (PE-V) and weathered (PE-W) particles. The ingested types of particles, but significantly more than (p = .0317), based on dosed by weight (mg ml-1) not when considering particle number (PE-V: 1.18 ± 0.16 PE-W 1.86 0.66 ml-1;). ingestion resulted...
The production and consumption of plastic products had been steadily increasing over the years, leading to more waste entering environment. Plastic pollution is ubiquitous comes in many types forms. To enhance or modify their properties, chemical additives are added items during manufacturing. presence leakage these additives, from managed mismanaged waste, into environment growing concern. In this study, we gauged, via an online questionnaire, expert knowledge on use, characteristics,...

Abstract The Norwegian water column monitoring program investigates the biological effects of offshore oil and gas activities in waters. In three separate surveys 2006, 2008, 2009, bioaccumulation biomarker responses were measured mussels (Mytilus edulis) Atlantic cod (Gadus morhua) held cages at known distances from produced (PW) discharge Ekofisk field. Identical studies performed all years have allowed data to be compared, addition, enabled potential environmental benefits a PW treatment...
Biological effects techniques have been used with the aim to further integrate biological measurements chemical analysis and apply these methods provide an assessment of mussel health status. Live native mussels were collected from selected coastal estuarine sites around British Isles, including rivers Test, Thames, Tees, Clyde, Lunderston Bay. A suite was undertaken on mussels, whole organism responses (scope for growth), tissue (histopathology), subcellular (lysosomal stability,...
Mussels (Mytilus spp.) are used frequently in biological effects studies and biomonitoring programs either as transplanted groups or native populations. However, a result of the similarities external morphology Mytilus, which influenced by environmental factors, visual identification is often never certain. Because differences contaminant bioaccumulation biomarker responses may occur among 3 mussel species Mytilus edulis, trossulus, galloprovincialis, bias likely. In current study, mussels...
The study assessed the environmental toxicity of three Norwegian mine tailings from Omya Hustadmarmor, Sydvaranger, and Sibelco, which are all released into a seawater recipient. Ecotoxicity assessments were performed on overlying water extracted tailings, transformation/dissolution waters obtained whole sediment assessment using suite marine organisms including algae, Crustacea, Mollusca. Overall, based evaluation data, Sibelco resulted in highest albeit at relatively high concentrations,...
In the Barents Sea region new petroleum fields are discovered yearly and extraction of products is expected to increase in upcoming years. Despite enhanced technology stricter governmental legislation, establishment industry may potentially introduce a source contamination area, as some discharges produced water will be allowed. Whether presence poses risk Arctic marine life remains investigated. The aim this study was examine effects exposure several compounds found water—a mixture selected...
The effects of humic acid (HA) on copper speciation and its subsequent toxicity to the sensitive early life stages Pacific oyster (Crassostrea gigas) are presented. Differential pulse anodic stripping voltammetry with a hanging mercury drop electrode was used measure species as labile (LCu; free ion inorganic complexes) total (TCu) respect increasing HA concentration. TCu LCu 50% effect concentrations (EC50s) in absence were 20.77 microg/L (95% confidence interval [CI], 24.02-19.97 microg/L)...
