文摘
- •
Dispersants preferentially disperse different fractions of petroleum hydrocarbons
- •
Dispersant SPC 1000 is much more effective than Corexit 9500A and Corexit 9527A
- •
Sediment adsorbs dispersed alkanes and PAHs in accord with the dispersion preference
- •
Lower doses of dispersant enhance sorption of PAHs, higher doses favor dissolution
- •
Dispersed n-alkanes and PAHs are susceptible to photodegradation under solar light
