Title: THE COMBINED EFFECT OF NUTRIENTS AND PETROLEUM HYDROCARBON ON PHYTOPLANKTONII.THE EFFECTS OF NUTRIENTS ON THE UPTAKE OF PETROLEUM HYDROCARBON BY PHYTOPLANKTON
Abstract: keletonema costatum,Heterosigma akashiwo,and Scrippsiella trochoidea were cultivated in the medium added with petroleum hydrocarbon and nutrients.The effects of nutrients on the uptake of petroleum hydrocarbon by phytoplankton were studied.Within the first 12 hours,when the nutrients were added according to the Redfield ratio,the uptake of petroleum hydrocarbon by the three phytoplanktons was the best.When nutrients concentration were in other ratios,the uptake order of petroleum hydrocarbon by phytoplanktons in the first 12 hours was N potential limitation P potential limitation Si potential limitation(only for S.costatum).Under the same nutrient conditions,S.costatum had the most uptake of petroleum hydrocarbon.In the first 12 hours,the decrease of concentration of petroleum hydrocarbon by the uptake of phytoplankton was quick.After 12 hours,the concentration of petroleum hydrocarbon in solution began to increase because the petroleum hydrocarbon was released from phytoplankton previously adsorbed.
