Risk assessment of complex organoarsenic species in food

EFSA Journal, Volume 22, Issue 12, December 2024.
Abstract The European Commission asked EFSA for a risk assessment on complex organoarsenic species in food. They are typically found in marine foods and comprise mainly arsenobetaine (AsB), arsenosugars and arsenolipids. For AsB, no reference point (RP) could be derived because of insufficient toxicity data.

Bottom Trawling and Multi‐Marker eDNA Metabarcoding Surveys Reveal Highly Diverse Vertebrate and Crustacean Communities: A Case Study in an Urbanized Subtropical Estuary

Environmental DNA, Volume 6, Issue 6, November–December 2024.
We demonstrated the effectiveness of eDNA metabarcoding as a valuable addition to bottom trawling for monitoring the species composition and spatial distribution of fish and crustacean communities in urban estuaries. We also showed that a multiplexed‐marker approach enhances species detection, especially in some taxa, for example, cartilaginous fish ...
