Chronic Toxicity Studies

Various toxicity tests can be performed to assess the chronic toxicity of different contaminants. Results after chronic toxicity testing on a product/ organism can be used to determine the guidelines and regulations for protection of organisms.

Chronic Toxicity testing of new compounds is essential for the drug development process. The chronic toxicity testing on various biological systems reveals the species toxic effects of the tested product. The toxicity of substances can be observed by



(a) To study the accidental exposures to a substance

(b) studies using cells/ cell lines

(c) Exposure on experimental animals.

The final report is on the basis of various experiments and methods used for toxicity testing of substances. The chronic toxicity testing helps in calculating no observed adverse effect level. This is important result of investigation.

We at toxicity are renowned for the best toxicity testing services. Here, we provide toxicity testing services for the chronic toxicity in the product. The chronic toxicity is developed because of adverse effect long term exposure to a toxicant or other stressor. It results in decrease of growth, reduced reproduction, or behavioral changes.

The chronic toxicity testing results related to toxicant is important to know to determine the water quality. Chronic toxicity tests are costly and difficult. The various difficulties are due to various challenges which are related to keeping control and keep organisms alive, maintaining water quality, retain constant chemical exposures, and time needed for tests. Because of this, acute toxicity tests we here have an expertise team who conduct ACRs and AFs test to know chronic toxicity of toxicants to organisms.

Chronic Toxicity is done to characterize the profile of a substance in a mammalian species following prolonged and repeated exposure. The routes of exposure are most likely the ones to which the human are exposed to that particular compound.

We at Toxicity India have expertise that follows the testing method with all the safety measures and follow all the standard of the performance of chronic toxicity testing. We at Toxicity assure to give an appropriate result which is giving us recognition among the top chronic toxicity testing laboratories. It is because of our scientific in-depth knowledge that we promise the most appropriate results. Chronic toxicity tests are expensive for the pockets and challenging for the investigator as the control is kept on the alive organism maintaining water quality, retaining constant chemical exposures and the time required for the tests.

The chronic toxicity test is to determining water quality which is not easy to determine.

Factors that influence toxicity

There are factors like chemical, biological or toxicological that increase or decrease the toxicity of toxicants or stressors. This further makes the interpretation of test results difficult.

Water quality guidelines are as per the results of acute and chronic toxicity tests.

Acute Toxicity test obtains the result of Criteria maximum concentrations (CMCs)

Chronic Toxicity test is to find the result of criteria continuous concentrations (CCCs)
