Step 5: Work out your introduction's risk to the environment
By now you know the human health risk of your introduction – medium to high, low or very low – which you completed in step 4.
To be able to finish your categorisation you need to work out the risks of your introduction to the environment. To work this out start at 5.1 and continue as far as you need to through each step.
Once you have your answer for the risk of your introduction to the environment – medium to high, low or very low – go to Step 6. In Step 6 you'll combine the human health risk and the environment risk for the final category of your introduction.
- Some introductions are always medium to high risk to the environment. This means they will be in the assessed introduction category and you need to apply for an assessment certificate.
- This step relates to introductions that are internationally assessed for the environment. If you are not using an international assessment, go to Step 5.3.
- There are 4 environment exposure bands - exposure band 1 has the lowest level of environmental exposure and exposure band 4 the highest level. Follow steps on this page to work out your environment exposure band.
- A chemical has an environmental hazard characteristic if it can cause damage, harm or adverse effects to the environment. Find out what you need to do to establish the environmental hazard characteristics of your chemical.
- The final step in working out your indicative environment risk.
