Risk assessment of nitrate and oxytetracycline addition on coastal ecosystem functions

- C. weissflogii was exposed to oxytetracycline and nitrate addition.
- Cell growth cycles could be shortened by 27-44%.
- Cell density was varied in the range of 73-121%.
- Coastal ecosystem functions were interfered by oxytetracycline and eutrophication.
- Risk assessment of aquaculture pollution on ecosystem function is investigated.
