Example sentences: predict

Finally, regression analysis showed that, for this type of runoff samples, the rapid screening biosensor was capable of predicting (a) the total amount of zinc present in the runoff samples (R2 of 0.93?0.98; p<0.05) and (b) the observed 72 h-EbC50s (R2 of 0.69?0.97; p<0.05).

The biotic ligand model (BLM) was developed to explain and predict the effects of water chemistry on the acute toxicity of metals to aquatic organisms.

The BLM is designed to predict metal interactions at the biotic ligand within the context of aqueous metal speciation and competitive binding of protective cations such as calcium.

Example sentences: potential

Nano zinc oxide (nZnO) is increasingly used in sunscreen products, with high potential of being released directly into marine environments.

The environmental behavior and the potential toxicity of copper nanoparticles (nano-Cu) in water are major concerns for assessing their environmental safety.

Both the zeta-potential of nano-Cu particles in E3 medium and the pH of the nano-Cu suspension showed no change during a 24 hour period.

Example sentences: expose

Hatchability was also decreased at a dose of 0.06mg/l cadmium, and almost no fry were hatched when exposed to 0.61mg/l.

Pycnoses were seen during 1-4 days after hatch in the brains of fry exposed to a particularly high concentration of cadmium.

Being part of a large inter-disciplinary research project, this study presents the bioavailability of zinc in runoff water immediately after release from the surface of 15 different commercially available zinc-based materials exposed to the urban environment of Stockholm, Sweden.

Example sentences: concentrate

The results depend on metal concentration and range from developmental disturbances to death of the embryo.

When the embryos and the fry were exposed to cadmium at a concentration of 0.06mg/l, survival time was shortened.

With increasing concentration of cadmium, survival time decreased even more.

Example sentences: chemical

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.

Chemical speciation modelling revealed that most zinc (94.3?99.9%) was present as the free Zn ion, the most bioavailable speciation form.

Both chemicals are toxic to medaka, in particular Zpt, which also causes teratogenic effects such as spinal cord deformities in embryos at very low, sublethal concentrations.

Example sentences: accumulate

Waterborne metals may accumulate in the gonads of spawners and adversely affect gamete production and viability, or exert direct toxic influence upon developing embryos.

The egg shell does not fully protect the embryo against metal penetration, particularly during the swelling phase; thus, metals may accumulate in the egg.

Cd was mainly accumulated in the egg's outer shell chorion (61%) and only small amounts passed through the chorion into the perivitelline liquid (38%) and embryo (1%).

Example sentences: medium

To establish comparative sensitivity, a standard medium (International Organization for Standardization [ISO]) was used.

The eggs were, therefore, exposed to cadmium solutions ranging from 10.0 to 300.0 mg Cd/liter for 1 hr, and then they were transferred to cadmium-free medium.

The present study was undertaken to characterize the properties of nano-Cu in E3 medium, such as size changes, solubility, zeta-potential and pH, and to test the toxicity of nano-Cu suspension to zebrafish embryos.
