“…Sandgaard et al 10.3389/fmars.2022.1100567 plastic ingestion because of food item similarity with MPparticles and their lack of ability to differentiate the two (Bour et al, 2021). In fact, sediment ingestion is recognized as the major influx pathway in particle-ingesting organisms for many conventional and emerging contaminants (Chiaia-Hernańdez et al, 2022), including MPs (Pinheiro et al, 2020). For aquatic organisms, the chance of encountering and ingesting MPs increases with MP concentration (Bour et al, 2021).…”

Microplastics (MPs) are ubiquitous in the marine environment. Here, most MPs are expected to sink, either due to polymer density or environmental processes, such as biofouling, leading to sediment being proposed to act as a final sink for marine MPs. There is a discrepancy between the anticipated accumulation of MPs in the sediment compartment and the MP experiments conducted, since most MP effect studies have been conducted with pelagic species using water-only exposures. Here we address fundamental questions in relation to MP pollution to close the knowledge gap related hereto. A systematic literature search was performed to address these questions. We found that benthic invertebrates ingest MPs and that, even though these organisms evolutionary are adapted to handle particles, adverse effects may be observed upon ingestion of MPs. The analysis further revealed that there is a major knowledge gap on the impacts of sediment-associated MPs in marine, benthic invertebrates. To facilitate further and structured research within this topic, we recommend more studies with emphasis on the sediment as an important exposure pathway, and to focus on sediment-associated MP effects on benthic invertebrates. We recommend studies with ecological relevant exposure concentrations and ecological relevant exposure durations with emphasis on impacts on population- and community-level to reduce the knowledge gap within this central area of MP pollution research.

“…Generally, sediments can function as important sinks or sources of contaminants depending on contaminant properties, sediment characteristics, water body features, and hydrodynamic factors (e.g., storm events and variable flows, bioturbation) (e.g., Chiaia‐Hernández et al 2022). PFASs in‐sediments are primarily a result of partitioning of PFASs from contaminated surface water.…”

“…These compounds can be released by mechanical abrasion (Stolz, 2000), arriving in watercourses that receive turbined water (Estoppey, 2022). In some situations, sediments highly contaminated by such releases could act as secondary sources (not as sinks) (Chiaia-Hern andez et al, 2022;Mustajärvi et al, 2017). These hypotheses may require more data (i.e., repeating or expansion of the acquisition stage) to be adequately tested before moving to the next stages.…”

Water contamination is a growing concern in society. New environmental laws are being enacted to define intolerable human activities, and their enforcement is increasingly supported by forensic science. However, water contamination is a broader security issue that is not only caused by illegal human behavior. Risk‐based approaches are needed to prevent (re)occurrence of incidents and minimize their negative consequences. This can be achieved through the formalization of a monitoring process producing intelligence (i.e., actionable knowledge), crucial to detect recurring incidents, and guiding decision‐makers in their choice of preventive and responsive actions. In this perspective, forensic science has a key role to play in integrating vestiges from water‐contaminating activities (i.e., traces) in such a problem‐solving process. Information conveyed by traces allows detecting similarities among contamination events (i.e., patterns), inferring common causes, and better understanding of mechanisms and consequences of water contamination. The different stages of the process will be described and illustrated through a real case example. Current barriers to the implementation of such a process are then discussed, showing how systemic issues and complexity may prevent the establishment of links across contamination events, thus negatively impacting the generation of intelligence. To overcome these obstacles, we underline the importance to initiate local and size‐limited approaches by implementing relatively simple and flexible systems. New knowledge can be used to improve local situations and help stakeholders to understand the benefits of such a process; then, by a bottom‐up iterative learning process, the approach can be given a greater ambition at a larger scale.This article is categorized under: Forensic Science in Action/Crime Scene Investigation > Special Situations and Investigations Crime Scene Investigation > From Traces to Intelligence and Evidence Forensic Chemistry and Trace Evidence > Forensic Food and Environment Analysis
