Example sentences: approach

The BLM approach has gained widespread interest amongst the scientific, regulated and regulatory communities because of its potential for use in developing water quality criteria (WQC) and in performing aquatic risk assessments for metals.

This journal issue includes papers that describe recent advances with regard to the development of the BLM approach.

The research results that are described in the papers found in this journal issue represent a distinct milestone in the ongoing evolution of the BLM approach and, more generally, of approaches to performing ecological assessments for metals in aquatic systems.

Example sentences: specific

The biotic ligand is defined as a specific receptor within an organism where metal complexation leads to acute toxicity.

The importance of the choice of water-type is shown by changes in the relative ranking of CTPs, which are equally influenced by water chemistry and inherent metal-specific differences.

In these models key parameters, as absorption and elimination rate constants, are predicted based on chemical specific properties and physiological characteristics.

Example sentences: similar

For other organisms, it is hypothesized that a biotic ligand exists and that mortality can be modeled in a similar way.

Similarly, values for total Cd2+ indicated higher concentrations in those eggs exposed prior to??and during??water hardening.

Ongoing studies must now address the development of more realistic exposure conditions of the gametes by using incubation media with osmolarities similar to surface waters, and by shortening duration for gamete exposure.

Example sentences: significant

Although SOD and MT expressions were not significantly increased in nZnO-treated medaka compared to the controls, exposure to ZnO caused a significant up-regulation of SOD and MT.

The embryo toxicity of nano-Cu at 0.01 and 0.05 mg/L showed no significant difference from Cu2+ at the corresponding concentrations (0.006 and 0.03 mg/L), but 0.1 mg/L nano-Cu had a greater toxicity than 0.06 mg/L Cu2+.

DOM-concentrations over 15 ppm carbon (C) decreased Cd-uptake significantly.

Example sentences: method

This report describes a study in which in vitro fertilization methods were used to expose medaka (Oryzias latipes) eggs to cadmium (Cd2+).

Also, sensitive methods to localize Cd2+ and to delineate the transfer from the chorion to the embryo are needed.

The method uses for calculation (1) USEtox for environmental fate, (2) WHAM 6.0 for metal partitioning and speciation in aquatic systems, and (3) Biotic Ligand Model (BLM) for average toxicity.

Example sentences: environment

Corrosion and runoff from zinc-coated materials and outdoor structures is an important source for the dispersion of zinc in the environment.

Runoff water was analysed chemically and evaluated for its possible environmental impact, using both a biosensor test with the bacteria Alcaligenes eutrophus (BiometR) and the conventional 72 h growth inhibition test with the green alga Raphidocelis subcapitata.

Rates of malformation in medaka fry from paddies treated twice a week with anti-dandruff shampoo (0.18?0.37 μL/L each time) over a period of 4 months were within the natural background, perhaps due to the quick dissipation rate of this chemical in the environment.

Example sentences: data

Initial application is made to the fathead minnow data set reported by R. Erickson and a water effects ratio data set by J. Diamond.

Analysis of the ecotoxicity data also suggested that the observed toxic effects were due to the presence of Zn2+ ions.

At first glance, it appears that a large amount of data are required for a successful application.
