Objectives
2 To examine acute toxicities of the two different types of nZnO to three model marine organisms, the diatom Thalassiosira pseudonana, copepod Tigriopus japonicus and mussel Perna viridis under the different combinations of salinity and temperature. Special attention will be paid on their interacting effects on the resultant toxicity of nZnO. The results will be essential to the regulation of the use and discharge of nZnO in tropical and subtropical coastal regions. 3 To elucidate possible underlying molecular mechanisms of the nZnO toxicity to T. pseudonana, T. japonicus and P. viridis under different salinity and temperature regimes. The results of this part of the study and those from Objective 1 will provide scientifically sound explanations for the patterns revealed in Objective 2.
