About 2.5 million t of sedimentary phosphorite mine tailings, highly enriched with Cd, Cr, Cu, Ni, Fe, F, and Zn, are dumped annually in the coastal waters of Togo without any pre-treatment, causing serious pollution problems in the region. We conducted bioaccumulation investigations on fish and crustaceans sampled from the polluted coastal zone. The highest concentrations of metals in fish and crustacean were found close to the tailings outfall and the values decreased further away from the…

Role of phosphorous mining in mobilization and bioaccessibility of heavy metals in soil-plant system: Abbottabad, Pakistan
Indiscriminate anthropogenic activities have considerably changed biogeochemical balance of naturally occurring heavy metals and posed serious threat to the environment. The phosphate rock (PR) mine…
Evaluation of mercury, lead, and cadmium in the waste material of crevalle jack fish from the Gulf of Urabá, Colombian Caribbean, as a possible raw material in the production of sub-products.
The Gulf of Uraba, currently considered a national strategic ecoregion, could be threatened by the presence of heavy metals such as mercury (Hg), lead (Pb), and cadmium (Cd), which directly affect…
Evaluation of mercury, lead, and cadmium in the waste material of crevalle jack fish from the Gulf of Urabá, Colombian Caribbean, as a possible raw material in the production of sub-products
TLDR
Considering the obtained results, it is not recommended to use the waste material for the production of fish meal or fish silage due to the adverse effects it could cause on both animals and humans.
Polycyclic aromatic hydrocarbons and trace metal contamination of coastal sediment and biota from Togo.
TLDR
Overall, concentrations of both PAHs and trace metals in sediment tend to increase from the coastline to the open sea (2 km offshore), attributable to the increasingly finer texture of coastal sediment found offshore, which has a terrigenous origin and appears loaded with various contaminants through adsorption processes.

Heavy metal concentrations in gill and liver tissues of Rutilus kutum and Chelon aurata in the coast of Babolsar, southern Caspian Sea
TLDR
The results showed that liver tissue of C. aurata significantly accumulated higher concentration of Cd, Pb and Zn compared to that of R. kutum , but these results were not significant for gill tissue.
Towards Regulatory Criteria for Discharging Iron-rich Mine Water into the Sea
Appropriate criteria are needed for regulating the discharge of mine water into the sea. Simply applying criteria developed for freshwater ecosystems to marine settings would be naïve and highly…
