METHOD OF ESTIMATING TOXIC EFFECT OF CHEMICALS ON FISH ORGANS AND TISSUES

摘要

FIELD: analytical methods in ichthyology.;SUBSTANCE: method comprises microscopic investigation of homogenates organs and tissues of fish exposed to exogenous chemical factors. Homogenate in the form of drop is placed onto the surface of slide plate, dried at room temperature for 24 h, and resulting samples are observed in polarized light. When colored anisotropic formations become visible, toxicity of a chemical is stated.;EFFECT: simplified procedure and increased rapidity of estimation.;2 tbl, 3 ex
