10788055Biological effects of contaminants in musselsEdited by MartynC.100015211layer_information_pageund1523446835152353351400152353351455- <p>Contaminants and effects monitoring is undertaken in Scottish coastal and offshore areas as part of UK Clean Seas Environment Monitoring Programme (CSEMP). Shellfish from around the Scottish coastline are monitored for contaminants; this is done primarily by SEPA, although MSS undertakes a limited biological effects monitoring programme. Biological effects that MSS have measured in mussels include: stress-on-stress, lysosomal membrane stability and genotoxicity (Comet assay). These are all ICES-recommended endpoints.</p>
<p>There are three layers showing the 2016 assessments from the MERMAN database for:</p>
<ol>
<li>Stress-on-stress which shows an organism-level indicator of general stress. Higher values equate to less stress. </li>
<li>Comet Assay which shows cellular-level marker of exposure to genotoxic contaminants. Higher values equate to more damage / exposure to the contaminants.</li>
<li>Lysosomal Membrane Stability by Neutral Red Retention which shows cellular-level indicator of general stress. Higher values equate to less stress.</li>

- <p>Exposure to contaminants reduces the ability to survive environmental stresses. Stress on stress is a simple method of evaluating how stressed mussels are, based on their longevity when exposed to air; stressed organisms have a lower tolerance. SoS provides a whole-organism measure of the impact of contaminants and correlates with exposure in lab studies and in the field.</p>
<p>Exposure to some contaminants can cause genetic damage, which can progress to cause cancer or other genetic defects. The Comet assay can be used as an indicator of genetic damage (DNA strand break). </p>
<p>Lysosomal Membrane Stability is a sensitive indicator of cellular stress caused by contaminants, subject to environmental and endogenous influences.</p>
