Copper Toxicity Thresholds for Earthworm Dendrobaena veneta: Insights from a Site with Unique Monometallic Soil Contamination.

Ecotoxicological studies predominantly rely on artificially contaminated soils and fieldwork on contaminated soils remains scarce. This study focuses on the Kargaly site in the Orenburg region near the southern Urals, where a rare instance of monometallic soil pollution has occurred with copper (Cu). We established Cu toxicity thresholds for Dendrobaena veneta, a European nightcrawler, using soils collected along a Cu toxicity gradient (total Cu content of 121-10,200 mg kg-1) in a chernozem (Mollisol) agricultural field.

Extremely High Soil Copper Content, yet Low Phytotoxicity: A Unique Case of Monometallic Soil Pollution at Kargaly, Russia.

Ecotoxicological studies on soil metal toxicity often rely on artificially contaminated soils. A major difficulty in using soils contaminated by anthropogenic activities (e.g.

Slow Many-Body Delocalization beyond One Dimension.

We study the delocalization dynamics of interacting disordered hard-core bosons for quasi-1D and 2D geometries, with system sizes and timescales comparable to state-of-the-art experiments. The results are strikingly similar to the 1D case, with slow, subdiffusive dynamics featuring power-law decay. From the freezing of this decay we infer the critical disorder W_{c}(L,d) as a function of length L and width d.
