In marine ecosystems, arsenic (As) and total mercury (T-Hg) represent two of the major pollutants, particularly in fish due to their ecology and the affinity of these metal(loid)s with biological cycles. This study assessed the influence of total length, total weight, relative condition factor, and trophic levels of ten marine fish species from the Colombian Caribbean on As and T-Hg accumulation in muscle tissue, as well as the differentiation in accumulated amounts based on fish habitat type. In this context, Balistes capriscus exhibited the highest As median (7949.

- Understanding variations in total mercury (T-Hg) levels in fish is essential for both environmental and human health, particularly in the Atrato River basin, Colombia, where a study analyzed these influences using a dataset of 842 fish samples from 16 species.
- The research highlighted key factors affecting T-Hg accumulation, ranking them as follows: feeding habits, total length, estimated total weight, trophic level, water temperature, and pH, with temperature negatively impacting accumulation levels.
- The study revealed distinct T-Hg patterns based on fish habitat types and emphasized the need for comprehensive insights into biological and environmental factors to enhance biodiversity management strategies, while also noting potential biases in the modeling process.
The research assessed the exposure to total mercury (THg), lead (Pb), and arsenic (As) in Colombian wetland species of different trophic levels Platalea ajaja, Dendrocygna autumnalis and Nannopterum brasilianus. The results show high THg blood levels in P. ajaja (811.
