Contamination is one of the main causes of human intoxication thus can prose great danger to humans, plants and animals. There are different kinds of contaminants that can be present in the food, cosmetics, and pharmaceuticals that can compromise the quality of the products. One major group of contaminants are the base contaminants and heavy metals. 

Basic contaminants are usually organic molecules that can be accidentally added or synthesized during the production. These compounds are in general toxic and in some cases, carcinogenic. Heavy metals are metals ions that can be present in the air, water, soil, plants, animals and manufacturing industries that can extremely affect humans. 

One of the best methods of determining the amount of contaminants present is to precipitate them out of the solution. Precipitating the contaminants can be done through titration. For example, heavy metals such as cadmium, mercury or lead can be precipitated using hydroxides. Upon the reaction of hydroxides, metal hydroxides are formed. In this step, the determination of ksp values is necessary.

For organic bases, the titration with acid such as HCl or HNO3 is a good method in determining the amount of the contamination present in the samples. This case, acid dissociation constant is being used to determine the relative content of the contaminant. 

This method is helpful since it can be able to provide safety to people. Also, determining the possible contamination can eventually lower the casualty that might happen in the future. And finally, it can help save the environment because it can determine what action the people should do in order to maintain a clean and green environment.
