Trihalomethane formation potential of dissolved organic matter in a shallow eutrophic lake.
Dissolved organic matter (DOM) in water samples from the shallow eutrophic Lake Kasumigaura, the second largest lake in Japan, was fractionated and characterized by using resin adsorbents into 5Expand
Dissolved iron and its speciation in a shallow eutrophic lake and its inflowing rivers.
It has been suggested that iron is a limiting factor on bloom-forming cyanobacteria in lake water. Although the availability of iron for phytoplankton depends significantly on its speciation, littleExpand
A new algorithm for estimating chlorophyll‐a concentration from multi‐spectral satellite data in case II waters: a simulation based on a controlled laboratory experiment
This paper presents the spectral decomposition algorithm (SDA), a new algorithm for estimating chlorophyll‐a concentration in case II waters using multi‐spectral satellite data, which is based on aExpand
In-situ growth rate of Microcystis spp. and their growth-limiting factors: use of cellular RNA content
In 2003 and 2004, we conducted field investigations of a canal during the summer algal bloom to estimate the in-situ growth rate of Microcystis spp. and its limiting factors. Cellular RNA contentExpand
An application of the biotic ligand model to predict the toxic effects of metal mixtures.
The rapidly developing biotic ligand model (BLM) allows us to predict the toxicity of heavy metals in water of various chemistries; however, the current BLM predicts the toxicity of a single metalExpand
Voltammetric determination of dissolved iron and its speciation in freshwater
Analytical methods were developed to determine the concentration of total dissolved iron and its chemical speciation in freshwater using cathodic stripping voltammetry (CSV) with 1-nitroso-2-naphtholExpand
A useful new insecticide bioassay using first-instar larvae of a net-spinning caddisfly, Cheumatopsyche brevilineata (Trichoptera: Hydropsychidae)
A new insecticide bioassay for assessing the effects of acute insecticide toxicity on lotic insects was developed. It uses first-instar larvae of a net-spinning caddisfly, CheumatopsycheExpand
New Records of Four Grapsoid Crabs (Crustacea: Decapoda: Brachyura) from Japan, with Notes on Four Rare Species
Four species of semiterrestrial grapsoid crabs are recorded from Japanese waters for the first time based on material from the Ryukyu Islands. These are: Pachygrapsus planifrons De Man, 1888Expand
Growth characteristics and growth modeling of Microcystis aeruginosa and Planktothrix agardhii under iron limitation
Although iron is a key nutrient for algal growth just as are nitrogen and phosphorus in aquatic systems, the effects of iron on algal growth are not well understood. The growth characteristics of twoExpand
Temperature dependence on the pesticide sampling rate of polar organic chemical integrative samplers (POCIS)
Laboratory experiments were performed to determine the sampling rates of pesticides for the polar organic chemical integrative samplers (POCIS) used in Japan. The concentrations of pesticides inExpand
