Risk assessment of nitrate and petroleum-derived hydrocarbon addition on Contricriba weissflogii biomass, lifetime, and nutritional value

- T. weissflogii was exposed to No.0 diesel oil and nitrate addition.
- Cell growth cycles could be shortened as its 20-50%.
- Cell density was varied in the range of 38-310%.
- Coastal diatoms role was interfered by petroleum hydrocarbon or/and eutrophication.
- Risk assessment of petroleum hydrocarbon on the role of diatoms is fully investigated.
