Chemical degradation refers to the process by which a chemical substance breaks down into simpler compounds or elements due to various factors such as heat, light, or chemical reactions. This process can occur naturally or be accelerated by environmental conditions, leading to changes in the substance's properties and effectiveness. In many cases, chemical degradation is a concern in fields like pharmaceuticals and environmental science, where the stability of compounds is crucial. For example, pollutants in the environment can degrade over time, impacting ecosystems and human health. Understanding this process helps in managing and mitigating potential risks associated with chemical substances.
