Evanescent hormesis effect induced by environmentally relevant PFOS to marine Chlorella sp.

Perfluorooctanesulfonic acid (PFOS) is widely detected in the aquatic environment. More attentions were paid to its acute biotoxicity at high-dose concentrations, whereas the actual long-term effect (hormesis or inhibition of growth) of PFOS with environmental concentrations on marine phytoplankton remains unclear. In this study, marine Chlorella sp.

Role of traveling microplastics as bacterial carriers based on spatial and temporal dynamics of bacterial communities.

Microplastics (MPs) are considered as distinct substrates for bacterial colonization, they can carry bacterial communities to travel around environments. The bacterial communities on traveling MPs prefer to be gradually consistent with those on local MPs that were always in the same environment, and this process of change in the bacterial communities on traveling MPs was called 'localization'. However, the dynamics of localization process and their influencing factors are still unclear.
