The following points highlight the five tests conducted for determining the effect of toxicity on organisms. The tests are: 1. Full Life Cycle Tests 2. Partial Life Cycle Toxicity Tests 3. Most Sensitive Early Life Stage Toxicity Tests 4. Functional Tests 5. Bioassay in Toxicity Testing. Test # 1. Full Life Cycle Tests: These are typical chronic toxicity tests conducted [...]
In this article we will discuss about:- 1. Meaning of Biological Monitoring 2. Characteristics of Species used in Biological Monitoring 3. Approaches to Environmental Monitoring. Meaning of Biological Monitoring: The hazards from the industrial emissions and agriculture have led to the need of regular and frequent measurements of various toxic parameters. Simple physical and chemical determinations can be used to [...]
In this article we will discuss about the acute and chronic toxic effects of chemical exposure on organisms. Acute Toxic Effects: Acute toxic effects are those that occur shortly after exposure to a relatively high dose of a toxicant. These effects occur rapidly as a result of short term exposure of a few hours, days or weeks to a chemical. [...]
