Microplásticos encontrados em placentas humana

Primeira descoberta

Em 2019, microplásticos foram encontrados em 4 placentas humanas, revelando um problema desconhecido.

Contaminação crescente

Estudos em 2023 detectaram plásticos em 17 placentas e apontaram um aumento significativo na contaminação ao longo dos anos.

Análise mais abrangente

Com uma nova técnica, cientistas examinaram 62 amostras de placenta e encontraram microplásticos em todas elas.

Tipos de plástico encontrado

Mais de 50% dos microplásticos identificados eram de polietileno, usado em sacolas e garrafas descartáveis.

Efeitos desconhecidos na saúde

Os impactos na saúde do feto e da mãe ainda são incertos, mas preocupações aumentam com o tempo.

Pesquisas em animai

Estudos em camundongos sugerem que microplásticos podem atingir órgãos como o cérebro e afetar o desenvolvimento.

Possíveis fatores de variação

Diferenças na concentração de plásticos podem estar ligadas a dieta, idade materna e estilo de vida.

Futuro das pesquisa

Técnicas avançadas devem ajudar a entender melhor os riscos e os impactos desses poluentes.
