Particle size determines the short-term phosphorus availability in biochar produced from digestate solids.

Biochar pellets produced from the solid fraction of manure-based digestates are rich in phosphorus (P) and may represent a P source that is easy to handle and suitable for transport to P-deficient regions. However, the effect of feedstock composition and particle size on P availability in this type of biochar remains unexplored. To evaluate the effect of particle size on the short-term P availability in biochars derived from manure digestate solids, an incubation experiment was carried out, in which four biochars produced from digestate solids in powder and pellet form were incubated with three soils of low P content.

A case study of PAH contamination using blue mussels as a bioindicator in a small Greenlandic fishing harbor.

This study investigated the impact of local anthropogenic activity on the marine environment around the remote harbor of Qeqertarsuaq, West Greenland. Blue mussels (Mytilus sp.) were used as a bioindicator, and their physiological condition was found to decrease with increasing proximity to the harbor.
