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. Polluted sediments may negatively affect aquatic and semi-aquatic reptiles. Chemicals or minerals (e.g. coal ash, red mud and apatite) may be added to sediments to reduce or remove pollutants (e.g. Kim et al. 2014, Shin & Kim 2016).
