Definition: Bisphenoid is a type of metal that contains a mixture of polycyclic aromatic hydrocarbons (PAHs) and bisphenols, which are known to have adverse health effects on humans, such as breast cancer. Another example is the development of bisphenol A (BPA), which was originally produced by the U.S. Food and Drug Administration in 1970 for the production of plastic containers and packaging materials. However, it has been found that BPA can cause developmental defects, neurodevelopmental disorders, and even cancer. In summary, bisphenoid is a mixture of polycyclic aromatic hydrocarbons and bisphenols that have adverse health effects on humans, while bisphenol A (BPA) was originally produced to produce plastic containers.
