Study finds winter road salt severely harms BC salmon eggs, prompting calls for safer alternatives.

A study by West Coast scientists finds that road salt used in winter may be lethal to freshly fertilized salmon eggs. Salt levels in creeks spike during winter, reaching up to ten times the safe limit, leading to near 100% egg mortality. Researchers suggest municipalities reduce rock salt use, opting for brine solutions, and promote rain gardens to filter runoff. This could help protect future generations of BC salmon.
