Resumo
Plastics are one of the most common and persistent pollutants in ocean waters
and beaches worldwide, causing harmful effects on marine biota. The composition of
these plastics mainly includes polyethylene (PE) and polystyrene (PS). The marine
environment is impacted in various ways and, in extreme cases, diseases can emerge
among seafood-consuming inhabitants due to contaminants (such as the toxic additives)
in the plastic composition. Specifically, the objective of the present investigation is to
analyze ions and metals in PE and PS samples exposed in the Jurujuba region (Baía de
Guanabara, Rio de Janeiro, Brazil) for different periods using the Energy Dispersive XRay
Fluorescence (EDXRF) analytical technique. This analysis will help identify toxic
metals present in these polymer compositions as well as metals adsorbed on the plastic
surface, contributing to defining measures to address this issue. Samples (in triplicate)
were divided into three groups: I) Standard: sample available commercially; II) Control:
sample exposed only to ultra-pure water, in the dark with a controlled temperature of 25
degrees Celsius; III) Exposed samples in Jurujuba (Baía de Guanabara). This study is part
of a larger research project “Strengthening capacities in Marine and Coastal Environments
using nuclear and isotopic techniques” (IAEA/ARCAL: RLA7025). These results
emphases the toxicity of marine pollution and show that PE and PS polymers can act as
carriers of pollutants between ecosystems.
