“…biomass decreased slightly with an increase in temperature [29]. Some other studies also support this observation [30,31]. In the sorption studies of heavy metals, the observed enthalpy is comprised of contributions from the energetic effects associated with intrinsic adsorption step, dehydration effects of the metal ions inside the aqueous solution, in addition to any plausible contribution from the physical/chemical changes that the sorption sites might undergo as a result of sorption.…”

“…The accumulation of Ag + and AgNPs in plankton was probably due to their attachment to the cell surface of organisms or perhaps entering the cells directly (Miao et al, 2010). The accumulation of silver nanoparticles in zooplankton could be the result of absorption around carapaces since they are chitins and can absorb ions (Benguela and Benaissa, 2002). The adverse effects of silver nanoparticles on zooplankton include lower consumption rates and a reduction in swimming capacity (Gaiser et al, 2011).…”
