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… Expand

The Geochemical Characterization of Mine Effluents from the Phosphorite Processing Plant of Kpémé (Southern Togo)
Sedimentary phosphorites are being exploited in southern Togo. The ore is processed to high-grade purified commercial phosphorite by wet sieving, using water pumped directly from the sea. The… Expand
Metal accumulations in aquatic organisms and health risks in an acid mine-affected site in South China
TLDR
There is a positive correlation between distance from the mine and metal concentrations related to the flow of surface water and the habitat of aquatic organisms, and further reduction of metals is necessary to improve the effects of acid mine drainage in the catchment. Expand
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… Expand
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… Expand
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. Expand
Heavy elements in the phosphorite from Kalaat Khasba mine (North-western Tunisia): potential implications on the environment and human health.
TLDR
It was found that Cd concentrations exceed the allowed EC soil limits for growing crops, and Cd could have detrimental effects on human health and on the environment because a significant portion of Cd was found in the exchangeable form. Expand
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.

Assessment of Metallothioneins in Tissues of the Clam Megapitaria squalida as Biomarkers for Environmental Cadmium Pollution From Areas Enriched in Phosphorite
TLDR
MT levels did not correlate with high Cd levels in clams that had been collected from areas associated with phosphorite enrichment, however, for environmental monitoring, MT levels can be used as a first approximation of the presence of high levels of divalent metals in the environment. Expand
Metals in mangrove ecosystems and associated biota: A global perspective.
TLDR
In this review, mangrove forests have been classified in a continent-wise manner and most of the investigations detail the distribution of metals such as zinc, chromium, arsenic, copper, cobalt, manganese, nickel, lead and mercury although in some cases levels of vanadium, strontium, zirconium and uranium have also been studied.
