Ocean Acidification-Mediated Food Chain Transfer of Polonium between Primary Producers and Consumers
Phytoplankton and zooplankton are key marine components that play an important role in metal distribution through a food web transfer. An increased phytoplankton concentration as a result of ocean acidification and warming are well-established, along with the fact that phytoplankton biomagnify 210 P...

Phytoplankton and zooplankton are key marine components that play an important role in metal distribution through a food web transfer. An increased phytoplankton concentration as a result of ocean acidification and warming are well-established, along with the fact that phytoplankton biomagnify 210 Po by 3–4 orders of magnitude compared to the seawater concentration. This experimental study is carried out to better understand the transfer of polonium between primary producers and consumers. The experimental produced data highlight the complex interaction between the polonium concentration in zooplankton food, i.e. phytoplankton, its excretion via defecated fecal pellets, and its bioaccumulation at ambient seawater pH and a lower pH of 7.7, typical of ocean acidification scenarios in the open ocean. The mass of copepods recovered was 11% less: 7.7 pH compared to 8.2. The effects of copepod species (n = 3), microalgae species (n = 3), pH (n = 2), and time (n = 4) on the polonium activity in the fecal pellets (expressed as % of the total activity introduced through feeding) was tested using an ANOVA 4. With the exception of time (model: F 20, 215 = 176.84, p < 0.001; time: F 3 = 1.76, p = 0.16), all tested parameters had an impact on the polonium activity (copepod species: F 2 = 169.15, p < 0.0001; algae species: F 2 = 10.21, p < 0.0001; pH: F 1 = 9.85, p = 0.002) with complex interactions (copepod x algae: F 2 = 19.48, p < 0.0001; copepod x pH: F 2 = 10.54, p < 0.0001; algae x pH: F 2 = 4.87, p = 0.009).
