Physiological and avoidance responses of juvenile mud crab Scylla serrata to mercury
(Bioflux, 2014)
The physiological and avoidance responses of juvenile mud crab Scylla serrata to mercury was evaluated by determining mortality using a renewal-type acute toxicity test and assessing crabs’ ability to avoid toxic concentrations. ...
Uptake and depuration of mercury in the green mussel, Perna viridis Linnaeus (Bivalvia: Mytilidae)
(Science and Technology Information Institute, 1985)
P. viridis were exposed to 3.6 ppb, and 100 ppb mercury. The mussels were also fed with algae that had been precontaminated with mercuric acetate to give a final mercury concentration of 10 ppb. Mercury bioaccumulation ...
Tissue distribution of mercury and selenium in minnows, Phoxinus phoxinus
(Springer Verlag, 1990)
The protective effect of selenium against mercury toxicity has been extensively demonstrated in a number of studies (Burke eta]. 1977; Kasuya 1976). Since mercury uptake is not always diminished by the presence of selenium ...
Uptake and some physiological effects of mercury on water hyacinth, Eichhornia crassipes (Mart) Solms.
(SEAMEO, 1990)
The uptake and growth effects of mercury (Hg) on Eichhornia crassipes under field conditions and with lakewater as cultural medium were investigated. Absorption of the heavy metal increase with higher levels of Hg in the ...
Survival and heavy metal accumulation of two Oreochromis niloticus (L.) strains exposed to mixtures of zinc, cadmium and mercury
(Elsevier, 1994)
Two Nile tilapia strains of Oreochromis niloticus (L.) (Cichlidae, Teleostei) fingerlings were exposed to mixtures of zinc, cadmium and mercury. The two strains used were Chitralada or NIFI (originally from the National ...
Mercury and selenium interaction: A review
(Elsevier, 1991)
This paper reviews studies on mercury and selenium interaction. It includes the effects of selenium on mercury toxicity on the organism, organ/tissue, and subcellular levels. The paper also touches on possible mechanisms ...
Antioxidant activities and selenogene transcription in the European sea bass (Dicentrarchus labrax) liver depend, in a non-linear manner, on the Se/Hg molar ratio of the feeds
(Springer, 2022-05)
Feeding 3.9 and 6.7 mg Hg/kg (Se/Hg molar ratios of 0.8 and 0.4, respectively) for 14 days negatively affected <i>Dicentrarchus labrax</i> growth and total DNTB- and thioredoxin-reductase (TrxR) activities and the transcription ...
Resistance to a heavy metal mixture in Oreochromis niloticus progenies from parents chronically exposed to the same metals
(Elsevier, 1995)
Adult Oreochromis niloticus were mass spawned in concrete tanks. The one-month old progenies (F<sub>1</sub>) were exposed for two months to a mixture of 0.01 mg L<sup>−1</sup> Hg, 0.1 mg L<sup>−1</sup> Cd and 1.0 mg ...
Effects of long-term exposure to a mixture of cadmium, zinc, and inorganic mercury on two strains of tilapia Oreochromis niloticus (L.)
(Springer Verlag, 1993)
Tilapia are an economically important group of fish. They have a short generation period of 3-6 months, and exhibit successive breeding. In addition, their fast growth, herbivorous or omnivorous feeding habits, high food ...
