Phosphates can be either biological and hence degradiable or non- biological. There are biological phosphates which can be found in the human body for example. The non-biological phosphates are very resistance substances and take a very long time to degrade. Phosposphates used in detergents are chemically made in a lab and are inorganic (non-biological)they are designed to be strong so that they can remove dirt etc. because they are desgned to be hardy the result is that they are not able to be broken down easily like plant material in a compost pile etc
