The Behavioral and physiological impacts of the hormesis of chemical contaminants on embryonic zebrafish

Pharmaceutical chemicals are being produced, consumed, and excreted in human civilization at an increasing rate. These have the capacity to accumulate, especially environments such as freshwater systems, but there not been any major responses this threat yet present concentrations of is viewed dangerous. Previous research has shown that developing issue, supporting these chemicals, though large doses, impacts on exposed organisms. However, prior conducted examine specific effects hormetic “Hormetic concentration” defines levels where response a low dose chemical differs from high dose, were ranges concentration tested experiment. Zebrafish acquired zero days post fertilization, transferred medium containing appropriate for group they would be part of, used model aquatic organisms show resulting chemical, neural, physical concentrations.
