Assessing contamination from maritime trade and transportation on Iberian waters: Impact on Mytilus sp

Contamination derived from maritime transportation is not only linked to petroleum-based substances but also to transportation of other substances such as hazardous and noxious nature (HNS). Over the last decade, the maritime trade of HNS has been augmenting. However, levels of HNS in aquatic enviro...
