New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.Customary harvest plays a vital role in expressing Māori identity, maintaining relationships with place and whakapapa, and transmitting mātauranga across generations. However, re‐engaging with traditional practices can be constrained by ecological risks and regulatory frameworks, particularly in protected areas.

Chlor-alkali industrial contamination and riverine transport of mercury: Distribution and partitioning of mercury between water, suspended matter, and bottom sediment of the Thur River, France [PDF]
, 2006 Total dissolved and total particulate Hg mass balances were estimated during one hydrological period (July 2001–June 2002) in the Thur River basin, which is heavily polluted by chlor-alkali industrial activity.

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis
Reviews of Geophysics, Volume 64, Issue 1, March 2026.Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,

Analytical methods for mercury speciation in several matrixes: a review [PDF]
, 2008 Mercury is one of the hazardous contaminants that may be present in the environment. Moreover, its toxicological effects are strongly dependent on the chemical form of the element, being the organic species the most toxic.

Mercury and selenium relationship in a tropical estuarine fish
Frontiers in Marine Science, 2015 Aquatic systems have been considered as final sinks for persistent and bioaccumulative toxicants (PBTs), such as metals and organohalogen compounds. Among the trace elements, non-essential metals deserve special attention due to their toxicity.
