人类血液中首次发现微塑料颗粒(10)

“担心当然是合理的，”维塔克教授告诉《卫报》（The Guardian）。“这些颗粒就在那里，并被输送到整个身体。”他说，以前的研究工作表明，婴儿粪便中的微塑料含量比成人的高10倍，用塑料瓶喂养的婴儿每天要吞下数百万微塑料颗粒。
swallow
表示“吞咽，吞下，咽下”，英文解释为“to cause food, drink, pills, etc. to move from your mouth into your stomach by using the muscles of your throat”举个：
My throat is so sore that it really hurts when I swallow.
我的喉咙很痛，吞咽起来很难受。
“We also know in general that babies and young children are more vulnerable to chemical and particle exposure,” he said. “That worries me a lot.”
“我们也知道，一般来说，婴幼儿更容易受到化学品和颗粒物的影响，”他说。“这让我非常担心。”
vulnerable
表示“易受伤的；易受影响（或攻击）的；脆弱的”，英文解释为“able to be easily physically, emotionally, or mentally hurt, influenced, or attacked”举个：
I felt very vulnerable, standing there without any clothes on.
一丝不挂地站在那儿，我感觉自己不堪一击。
The new research is published in the journal Environment International and adapted existing techniques to detect and analyse particles as small as 0.0007mm. Some of the blood samples contained two or three types of plastic. The team used steel syringe needles and glass tubes to avoid contamination, and tested for background levels of microplastics using blank samples.
