Abstract
Despite increasing evidence on the presence of numerous contaminants of emerging concern (CECs) in the marine environment, their occurrence profiles are not well established yet. Many CECs and their transformation products (TPs) are often overlooked when using conventional target screening approaches, since reference standards are not always available. Suspect and nontarget screening (NTS) of CECs and their TPs were made possible with the advances in analytical techniques that allow to identify and (semi)quantify pollutants without the use of reference standards. Outcomes of literature review involving 30 studies dealing with suspect and NTS of CECs in marine environment samples are presented. The studies revealed the presence of 1567 CECs of anthropogenic origin detected in samples from 23 countries. Further advances in the harmonization of analytical protocols, methodological framework, and data exchange/dissemination platforms are required to make suspect and NTS suitable for regulatory purposes. Examples of the harmonization and automation of NTS workflows are discussed.
