TLDR
Lead tolerance may result from the ability of the tolerant individuals to sequester the metal and detoxify it in their tissues; the littorinids from Laxey had significantly higher rates of lead accumulation.
Benthic macro invertebrate fauna and physico-chemical parameters in Okpoka creek sediments, Niger Delta, Nigeria.
TLDR
The benthic macro invertebrate fauna and physico-chemical parameters in Okpoka creek sediments was studied for a period of one year and positive relationship exi sts between salinity and salinity, pH and temperature was strongly related with Ophidonais serpentine, Arenicola marina, Notomastus latreila and Tellina nymphalis.
Cadmium and lead levels in some fish species from Azuabie creek in the Bonny Esturary, Nigeria
TLDR
The concentrations of cadmium and lead were determined in seven fish species from the Azuabie creek in the upper Bonny estuary of the Niger Delta, which is associated with industrial and abattoir discharges, and were within values that may be considered safe for human consumption.
Interactive Effects of Copper, Cadmium and Lead on Zinc Accumulation in the Gastropod Mollusc Littorina Saxatilis
TLDR
Interactions of Cu and Zn in particular may have repercussions for interpretation of biomonitoring data in L. saxatilis as all populations showed similar patterns.
Effects of Sub-Lethal Concentrations of Diazinon on Total Protein and Transaminase Activities in Clarias gariepinus
TLDR
Protein concentration as well as ALT activities in gills and liver of Clarias gariepinus are more useful biomarkers of sub-lethal effects of diazinon than total protein, ALT and AST activities in plasma.
Polycyclic Aromatic Hydrocarbons in Sediment and Tissues of the Crab Callinectes pallidus from the Azuabie Creek of the Upper Bonny Estuary in the Niger Delta
The accumulation of Polycyclic Aromatic Hydrocarbons (PAH) in sediment and the flesh/carapace of the edible swimming crab Callinectes pallidus from Azuabie creek in the upper Bonny Estuary, Niger
Spatial and Temporal Variation of Physico-Chemical Parameters of Sediment from Azuabie Creek of the Upper Bonny Estuary, Niger Delta
The impacts of human and industrial activities on the physico-chemical quality of sediment of Azuabie Creek in the upper Bonny Estuary of the Niger Delta, Nigeria were studied. Major waste inputs
Accumulation of heavy metals from single and mixed metal solutions by the gastropod mollusc Tympanotonus fuscatus linnaeus from a Niger Delta estuary: Implications for biomonitoring
The usefulness of the intertidal gastropod Tympanotonus fuscatus L as a biomonitor of heavy metals in tropical estuaries was assessed. The periwinkles were collected from a site in the upper Bonny
