Offshore oil platforms release a lot of water back into the sea. This water can contain chemicals that don't break down easily. These persistent chemicals can harm the environment for a long time. Scientists needed a better way to find out what's in this water and how dangerous it is.

They came up with a new method called "Persistence-Directed Testing. " This method checks how well chemicals break down in the environment. They tested water from two oil platforms in the North Sea. The water was mixed with seawater and left for two months. Then, they used special tools to look for chemicals that didn't break down.

They found over 600 chemicals. Only a small number of these chemicals were persistent. But some of these persistent chemicals were quite harmful. They had structures that are known to be dangerous. This shows that the water from oil platforms might be more harmful than we thought.

The study also shows that we need better ways to treat this water before it's released into the sea. The current methods might not be enough to protect the environment. This is a big problem because oil platforms release a lot of water every day.

The study is important because it shows that we need to be more careful with the water from oil platforms. We need to find out what's in it and make sure it's safe before it's released. This is not just a problem for the North Sea. It's a problem for all the oceans where oil platforms operate.
