The liver plays a crucial role in metabolizing proteins and eliminating waste products from the body, including ammonia. Ammonia, a toxic byproduct of protein metabolism, is typically converted into urea in the liver—a process that allows for its safe excretion through urine. However, in cases of liver cirrhosis or hepatic encephalopathy, the liver's ability to process ammonia is compromised, leading to a dangerous accumulation.
Finally, the handbook encourages continued research and innovation in the field of plastic and polymer additives. As new materials and technologies emerge, the ongoing evolution of analytical methods will be essential to keep pace. Collaborative efforts between academia, industry, and regulatory bodies will contribute to the development of safer, more effective additives and enhance our understanding of their environmental and health impacts.
