Disinfection is perhaps the most critical function of chemical dosing. It involves the introduction of chemicals such as chlorine, chloramines, or ozone into the water to kill or inactivate harmful microorganisms. Chlorine, for example, is widely used due to its effectiveness and residual properties, which help to maintain water quality throughout the distribution system. The careful dosing of disinfectants is essential to balance efficacy and safety; too little may not effectively kill pathogens, while too much can lead to the formation of harmful byproducts.
One of the most widely used APIs, paracetamol is commonly found in pain relievers and fever reducers. Its mechanism of action primarily involves the inhibition of an enzyme responsible for producing prostaglandins, which are chemicals that promote inflammation, pain, and fever. The accessibility and effectiveness of paracetamol have made it a staple in over-the-counter medication.
