dc.description.abstract | The production of plastic started almost a century ago. Today, microplastic pollution is
ubiquitous, we can find microplastics literally everywhere and the marine environment is
not an exception. In the present study, we evaluate the effect of this pollutant on mortality
and DNA degradation in the marine zooplankton species Artemia salina. Two
experiments were carried out with two different population densities (low-density with n
= 15 and high density with n = 100, in a total volume of 1,000 mL) and were exposed to
three different concentrations of polystyrene microbeads (C0: Control, C1: 0.02 mg/L,
C2: 0.2 mg/L and C3: 2 mg/L) for 7 days and at a constant temperature of 20ºC. The
results showed an increase in the accumulated mortality of individuals subjected to the
highest concentrations. These effects were shown to be dependent on the factors of
population density and exposure time. In addition, it was shown that individuals subjected
to medium and high concentrations had a higher mortality risk compared to the lower
density and the control. DNA degradation levels could not be correlated with either
microplastic concentration or exposure time. | |
