* Consumption studies *

There are various tests for toxicity. However, i am only doing research on human studies. The 3 studies that i have found out are (1) Epidemiological studies (2) Biomarker research (3) Toxicity tests for hazard characterization in foods

(1) It is a study to establish the relationship between humans and the disease. It is used to evaluate te toxic substances and their effects have on living organisms. The disadvantages of this study is that human are exposed to a variety substances. Therefore, it causes difficulty to determine what types of effects a specific compound will cause. There are two different subclass of the studies, one is case -control. One of the disadvantages of this case control study is take it takes years to see the result.

(2) This is used for internal dose to analyse nutrients/ compounds in blood, plasma, blood cells, saliva, bile etc. It reflect phases betwwen external exposure and the disease that shown and include factors that cause change in this transition phases.

(3) This tests are done on foods that cause hazards in foods yet these hazards have not been identified. Therefore, this test is done to evaluate these hazards.
