人类血液中首次发现微塑料颗粒(12)

维塔克教授承认，塑料的数量和类型在血液样本之间有很大的不同。他说：“但这是一项开创性的研究，”现在需要更多的研究工作。他说，这些差异可能反映了在采集血样之前的短期暴露，例如含塑料内层的咖啡杯喝水，或戴着塑料口罩。
“The big question is what is happening in our body?” Vethaak said. “Are the particles retained in the body? Are they transported to certain organs, such as getting past the blood-brain barrier?” And are these levels sufficiently high to trigger disease? We urgently need to fund further research so we can find out.”
“最大的问题是我们的身体里发生了什么？”维塔克教授说。“这些颗粒是否保留在体内？它们是否被输送到某些器官，例如透过血脑屏障？而这些量是否高到足以诱发疾病？我们迫切需要资助进一步的研究，以便我们能够找到答案。”
