It is also used to make many different products such as medicines, vitamins, food flavorings, paints, dyes, rubber products, adhesives, insecticides, and herbicides. Pyridine can also be formed from the breakdown of many natural materials in the environment. Pyridine is primarily released to the environment from industries that make and use this chemical. Pyridine evaporates into the air very easily. In the air, it may take several months or years until it breaks down into other compounds.
Pyridine is very soluble in water.
In water or soil, it may be broken down in a few days to a few months by microscopic organisms. Pyridine sticks to soil particles. Pyridine probably doesn't build up in plants or animals. Everyone is exposed to very low levels of pyridine in air, water, and food. Workers may be exposed in industries that make pyridine or use it to make other products by breathing it in air or by touching it.
