Both Zpt and imidacloprid caused stress syndrome in juvenile medaka, with fish from Zpt-shampoo fields having a significantly lower weight to body length ratio than those from control fields.
As it often happens with stressed fish, a massive infestation by a Trichodina ectoparasite was observed in medaka from imidacloprid fields.
However, despite their high stress levels, fish from the Zpt fields did not suffer such infestation, supposedly because the disinfectant action of this biocide.

Example sentences: site
Specifically, the BLM does this in a way that considers the important influences of site-specific water quality.
Increases in waterborne Ca2+ had a protective effect on Zn toxicity, suggesting that this ion competes with Zn and that they share a common site of biological uptake.
The sites were representative of effluent-dependent or effluent-dominated streams common to the arid western United States of America (arid West) and a wide range of water quality variables were tested.

Example sentences: regulate
For fish, the biotic ligand is either known or suspected to be the sodium or calcium channel proteins in the gill surface that regulate the ionic composition of the blood.
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.
We found that Cr and Zn were accumulated in snail tissues, whereas Fe was regulated.

Example sentences: range
The results depend on metal concentration and range from developmental disturbances to death of the embryo.
The results depend on metal concentration and range from developmental disturbances to death of the embryo.
Following range finding exposures (2.5, 10, 20, 40 or 80 mg/l) under artificially controlled experimental procedures, results from hatching success and embryo malformations showed the earlier exposure interval more sensitive than the assay involving only the embryonated egg.

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.
