Why is it important to know what checmicals are producded in the body as decomposition proceeds?

Measuring and understanding the chemicals that are released during decomposition can be studied and the effects of these chemicals can be measured. Effects on the environment (soil composition, water quality, animal health) can all be affected by a decomposing body. When scientists are able to understand these effects, they can better prepare and prevent the harmful effects while reaping the benefits that could be useful.
