Background information and definitions
Sediments within aquatic environments can accumulate pollutants over time, such as those leaching from aquaculture systems, sewage outfalls or nearby agricultural fields. Marine or freshwater mammals may be negatively affected by polluted sediments, particularly those feeding on or near the bottom of rivers or seas, or in areas where sediments are frequently disturbed. Chemicals or minerals may be added to sediments to reduce or remove pollutants (e.g. Kim et al. 2014, Shin & Kim 2016).
