Pharmaceutical deltamethrin (Alpha Max), used as delousing treatments in aquaculture, has raised concerns due to possible negative impacts on the marine environment. A novel approach combining different scientific disciplines addressed this topic. Acute (mortality) and sublethal effects (i.e., fitness, neurological, immunological, oxidative responses) of exposure northern shrimp (Pandalus borealis) were studied laboratory experiments. Passive water sampling combined with sediment analyses...

Abstract The European Food Safety Authority assesses the safety of feed additives used in aquaculture, including for environment. sediment compartment is frequently environmental area most at risk from these chemicals. objective Task 1.1, as reported herein, was to develop standard exposure scenarios part project titled “Modelling Environmental Concentrations Chemical Substances Marine Sediment Resulting Their Application via Feed Aquaculture.” This report presents findings 1.1. To calculate...

Abstract The European Food Safety Authority (EFSA) assesses the safety of fish feed additives used in aquaculture. To evaluate their potential environmental risks, it is essential to calculate predicted concentrations (PEC) advance and compare them known exposure thresholds (first step) or predict no effect (second step). This report outlines a conceptual framework for developing model designed PEC sediment introduced into marine aquaculture through feed. represents processes that influence...
