• Biotesting

Environmental quality assessment using living organisms.

Biotesting is a method of determining environmental toxicity using test organisms that signal a hazard, regardless of which substances and in what combinations cause changes in vital functions in the test organisms. Because of its simplicity, rapidity and accessibility, biotesting has gained widespread acceptance worldwide and is increasingly used alongside analytical chemistry methods. There are 2 types of biotesting: morphophysiological and chemotactic. The chemotactic method is more accurate because it uses a special instrument, while the morphophysiological method allows a more precise description of what happens to test objects, for example in contaminated water.

Test objects are bioindicators (plants and animals) used to assess air, water or soil quality in laboratory experiments.
