RESUMO

O plástico é uma realidade inescapável da sociedade moderna. Pode ser encontrado em praticamente todos os produtos comercializados actualmente, graças à sua utilização num vasto universo de aplicações. Contudo, é esta mesma versatilidade e características altamente desejáveis que levaram à crescente acumulação de plástico no ambiente. Plásticos mais pequenos, denominados micro- e nanoplásticos, são, no entanto, um perigo moderno cujos riscos não ainda totalmente compreendidos. Estas limitações advêm não só do seu destino e comportamento no ambiente, que ainda carecem de investigação, mas também das inerentes restrições tecnológicas e metodológicas que, até ao momento, têm impossibilitado um conhecimento preciso e detalhado dos processos químicos, físicos e biológicos nos quais estes materiais podem participar quando nos diferentes ecossistemas. Consequentemente, é necessária mais investigação e informação que permitam uma melhor compreensão dos impactes destes materiais no ambiente.

Palavras-chave: Plástico; microplásticos; nanoplásticos; ambiente.

ABSTRACT

Plastic is an inescapable reality of modern society. It can be found in almost any and every product used nowadays, owing to its endless range of applications. However, it is this same versatility and desirable characteristics that have led to the exponential accumulation of plastic in the environment. Smaller, and perhaps more pervasive plastics - dubbed micro- and nanoplastics - are a modern hazard that have yet not fully understood risks. These stem not only from their fate and behavior that are still under investigation, but also from the inherent technological and methodological limitations that have, so far, impeded a detailed and precise knowledge of the chemical, physical and biological processes that these materials may become involve in ecosystems. Hence, more information and research in required to better understand the impacts of these materials in the environment.
