  author={Takayoshi Toyota and T. Nakashima},
  journal={Journal of Oceanography},
To clarify the beneficial roles of naturally occurring organic ligands on the growth of phytoplankton in newly upwelled water, phytoplankton culture experiments using disphotic zone water were conducted to discriminate between the effects of EDTA in the detoxification of certain toxic metal ions and increasing the availability of essential metals. Culture media were prepared by adding EDTA and Chelex-100, separately or in combination, to disphotic zone water samples. Our proposed working…

Depuration of cadmium from Chlamys farreri by ZnSO4, EDTA-Na2 and sodium citrate in short time.
The results showed that Cd was depurated exceeding 20% within 12 h by the combination of 0.15 g/L sodium citrate, 0.28 G/L ZnSO4, and 0.42 g-Na2, so the reduction of Cd in the whole organism of Chlamys farreri may occur.
The role of ethylenediaminetetraacetic acid in green-lipped mussel (Perna canaliculus) embryo development: A biochemical and morphological characterization
It is shown for the first time that without EDTA embryos show oxidative stress and ultrastructure abnormalities, which adds significantly to the understanding of the beneficial role(s) of EDTA in aquaculture.
Minerals in Deep Ocean Water and Their Effects on Physiological Functions
Deep Ocean Water (DOW) is sea water from at least 200m below the sea surface and has such characteristics as being clean and rich in mineral components compared to surface seawater. Recently, DOW has

It is hypothesized that EDTA controlled formation of hydroxyl radicals via trapping Fe(II) ions reversibly in oxidized DNA with or without natural antioxidants-flavonoids and anthocyanins-and synthetic antioxidants, Trolox and 2H-pyrrole and DMPO.
Assessment of Redox Status in Commercial Bottled Mineral Water
Redox status in commercial bottled mineral water, ILOHAS, Mt. Fuji, Choju, Crystal Geyser, Volvic, Evian, Vittel, Perrier and Contrexville was studied. Among the 9 water, Choju and Perrier showed
Alleviative effects of deep‐seawater drinking water on hepatic lipid accumulation and oxidation induced by a high‐fat diet
Deep seawater (DSW)300, DSW900, and DSW1500 drinking waters shows a preventive effect on development of hepatosteatosis induced by a high‐fat diet.
Three different deep-seawater (DSW) treated by means of reverse osmosis (RO DSW), electrodialysis (ED DSW) and 10% (v/v) dilution with ddH2O (10% DSW) were as treated groups, while distilled water
Deep Sea Water Improves Abnormalities in Lipid Metabolism through Lipolysis and Fatty Acid Oxidation in High-Fat Diet-Induced Obese Rats
The results showed that body weight, liver, adipose tissue, hepatic triglycerides and cholesterol, and serum parameters in the high-fat diet + DSW groups were significantly lower compared to the HFD group.
Difference between deep seawater and surface seawater in the preventive effect of atherosclerosis.
The results suggested that the deep seawater was useful for the prevention of hyperlipidemia and arteriosclerosis compared to the surface seawater, and it was found that reduction of the LDL cholesterol level and enhancement of GPx activity were involved in its effects.
Cardiovascular protection of deep-seawater drinking water in high-fat/cholesterol fed hamsters.
It is demonstrated that DSW drinking water benefits the attenuation of high-fat/cholesterol-diet-induced cardiovascular disorders in hamsters.


Trace metal‐chelator interactions and phytoplankton growth in seawater media: Theoretical analysis and comparison with reported observations 1
Effects of trace metal chelators in seawater are examined theoretically in terms of equilibrium chemical speciation in seawater; of chemical interactions between all metals, naturally occurring
Growth inhibition of phytoplankton populations cultured in disphotic zone water by insufficient amounts of dissolved organic carbon
The results obviously show that prolonged lag period at least occurs in low DOC water, which can explain the observations by Barber and Ryther (1969) that low photosynthetic carbon uptake rate occurs in newly upwelled lowDOC water.
Limitation of productivity by trace metals in the sea
Some trace metals such as Fe, Ni, Cu, and Zn are essential for the growth OF phytoplankton. The concentrations of these essential trace elements in seawater are so low as to limit their availability
Silicon and the ecology of marine plankton diatoms. II. Silicate-uptake kinetics in five diatom species
Investigation of the rate of silicate uptake with varying silicate concentration in the medium with marine diatom species found growth limitation by low silicate concentrations could be a cause of species succession in marine plankton-diatom blooms.
Limitation of marine phytoplankton reproductive rates by zinc, manganese, and iron1
The habitat-related patterns in zinc, manganese, and iron requirements of oceanic and neritic species are consistent with the oceanic-neritic distributions of concentrations of these metals.
Chelating resins for the concentration of trace elements from sea water and their analytical use in conjunction with atomic absorption spectrophotometry
Abstract An investigation has been made of the uptake of trace elements from both distilled water and sea water by the chelating ion-exchange resins Chelex-100 and Permutit S1005. The resins retained
Availability of colloidal ferric oxides to coastal marine phytoplankton
The results suggest that the availability of colloidal iron to provide a source of iron for phy toplankton is related to the thermodynamic stability and kinetic lability of the colloidal ferric oxide phases, which probably control the uptake rate of iron by phytoplankon.
Effects of ligand speciation on determinations of the complexing abilities of strong ligands in natural waters
The presence of organic ligands (L) whose conditional stability constants (K′ML) are strong enough to allow them to form complexes with copper has been reported in oceanic waters. However, there is
The relationship between cupric ion activity and the toxicity of copper to phytoplankton
Culture experiments with the estuarine diatom Thalassiosira pseudonana (clone 3H) in highly chelated seawater media demonstrate that growth rate inhibition and copper content of cells are related to
Copper ions as poison in the sea and in freshwater
It has recently been shown that ocean water in the centres of upwelling becomes suitable for plankton growth only after the addition of a chelator, suggesting that a large part of the Cu found in the subsurface waters of the oceans is present in ionic form.
