In the air quality directive (2008/EC/50), the EU has set a target value and a long term objective value for ozone (O3) for the protection of human health. Target value: the maximum daily eight-hour mean may not exceed 120 micrograms per cubic metre (µg/m3) on more than 25 days per calendar year averaged over three years. Long term objective value: the maximum daily eight-hour mean may not exceed 120 micrograms per cubic metre (µg/m3) within a calendar year.

Where you can, choose organically farmed fish such as sea bass, salmon and trout.
Non-organic fish uses large quantities of chemicals and antibiotics which can affect other animals in the food chain. It is also worth bearing in mind that to produce a 3 kg farmed salmon, 15 kg of fish are caught in the wild to provide its meal and oil.
