Looking at five samples each of three common bottled water brands, researchers found particle levels ranged from 110,000 to 400,000 per liter. The average was around 240,000, the study said. The research appeared recently in the publication Proceedings of the National Academy of Sciences. Nanopa...
The average liter of bottled water has nearly a quarter million invisible pieces of very small plastic known as nanoplastics, a recent study says. 最近的一项研究表明,每升瓶装水中平均含有近 25 万个看不见的非常小的塑料,即纳米塑料。 Researchers found the nanoplastics with a microscope using dual ...
Researchers are unsure just how dangerous microscopic pieces of plastics are for people. TheWorld Health Organizationin 2019 said that the potential hazards associated with microplastics come in three forms: from the particles themselves, chemicals that make them up and "microorganisms that may atta...
It is the most common type of marine debris (垃圾) found in the ocean. Plastic debris can come in all shapes and sizes and be harmful to our ocean and water life. Micro-plastics come from various sources, including larger plastic debris that degrades into smaller pieces. In addition, ...

Plastic is a manufactured material designed to be durable and withstand the elements. So, it does not break down in the environment but persists for a long time. When it starts to break down, it doesn’t disappear but instead breaks down into smaller and smaller pieces. It eventually resulte...

Orb: "Plastic waste doesn't biodegrade; rather, it only breaks down into smaller pieces of itself, even down to particles in nanometer scale — one-one thousandth of one-one thousandth of a millimeter. Studies show particles of that size can migrate through ...
(1)根据后句It's in our food and drinks,in the clothes we wear and even in the air we breathe.(它存在于我们的食物和饮料中,存在于我们穿的衣服中,甚至存在于我们呼吸的空气中。)可知说的是到处都是,结合选项,应说更糟糕的是,到处都是。故选A。(2)根据前句Some very tiny pieces...
In addition, micro-beads, a type of smaller micro-plastic, are very tiny pieces of manufactured polyethylene (聚乙烯) plastic added as exfoliants (去角质剂) to health and beauty products,like toothpastes. These tiny particles easily pass through water systems and end up in the ocean, posing...
