Byproducts - The Phosphate Risk

In Florida, the phosphate rock is sent to processing plants in which it undergoes "wet process" to convert it into phosphoric acid. In the process, sulfuric acid is added to the phosphate to create phosphoric acid — which is easily absorbed by plants. Phosphogypsum (or "gypsum"), a radioactive material, is a byproduct of this process.
