Ecological patterns of trace and essential metal bioaccumulation in marine fish from the Gulf of California, Mexico
A new study from World Data Ocean examines ecological patterns of trace and essential metal bioaccumulation in marine fish from the Gulf of California, Mexico. Researchers evaluated concentrations of eleven elements—including arsenic, selenium, and uranium—across three fish species from distinct feeding guilds at two locations, revealing significant variability linked to species ecology, regional geology, and historical mining activity. Notably, selenium exhibited high bioaccumulation, while arsenic concentrations displayed interspecific differences.
‘Forever chemicals’ could be aging dolphins beyond their years
New research reveals a concerning phenomenon: common dolphins in New Zealand are exhibiting biological ages significantly exceeding their calendar ages, potentially shortening their lifespans. Scientists hypothesize that exposure to trace metals and persistent “forever chemicals” – per- and polyfluoroalkyl substances – is contributing to this accelerated aging process. This finding underscores the urgent need to assess the impact of environmental contaminants on marine mammal health. For further insights into the complexities of island marine ecosystems, explore our analysis of fish assemblages in Zhejiang, China.
