Nature Communications, Published online: 11 June 2026; doi:10.1038/s41467-026-74313-4 Hg isotopes reveal a negative Δ¹⁹⁹Hg–δ²⁰²Hg relationship restricted to Permian–Triassic crisis intervals, indicating enhanced volcanic Hg loading and providing a framework for tracing Siberian Traps eruptive pulses and environmental change.
