Short summary
This study explores how nanoplastics threaten the freshwater beneath small islands, which is vital for local communities. Conventional water management targets saltwater intrusion, but oceanic nanoplastics spread faster and wider, reaching wells sooner. Salt-based safety standards thus grossly underestimate nanoplastic risks. To protect island water, we must now consider this emerging plastic pollution when placing wells and planning pumping.

Short summary
The accurate identification of NO3--N pollution sources are pivotal to the assessment of groundwater pollution risks. However, current studies on NO3--N source apportionment simplifies complex multi-layer aquifer systems into single-layer models without accounting for the impact of occurrence conditions. In this study, we quantitatively identify distinct NO3--N pollution sources in unconfined and confined groundwater, highlighting the critical role of occurrence conditions for management.

Short summary
Geological carbon sequestration is a promising strategy to mitigate climate change. We developed an integrated numerical framework that combines injection, dissolution, mixing, reactions, and ripening. Key results indicate that dissolution restricts plume lateral migration and constitutes about 40 % of storage. Geochemical reactions contributes less than 1 % but promotes dissolution and long-term security. Over tens of millennia, ripening redistributes residual CO₂, forming a stable gas cap.
