Abstract:

The effects of crude oil and dispersant exposure on mesozooplankton were investigated. This dataset includes concentration and bioaccumulation factors of PAHs in Acartia tonsa and mesoplankton communities, composition and mortality of mesozooplankton exposed to UVB radiation/sunlight and dispersant, and sublethal effects of crude oil and bioaccumulation factors of PAHs in Acartia tonsa fed with protozoans.
