In a partnership with the 5 Gyres Institute, Trash Free Maryland took to the Chesapeake Bay in November to study the presence of micropiastics in the water. Setting out from Deale, Md., the research team collected seven samples by dragging a trawl (拖网) for an hour at a time. The trawl was fitted with a cone-shaped (锥形的) net, whose holes measure 330 microns (微米) wide, about the width of two to three strands of human hair. Water flows through the main opening and the fine mesh (网眼) of net ensures anything suspended in the water is trapped behind.
In seven samples, the net picked up algae (海藻) trash, foam and plastic. According to the 5 Gyres Institute representative, the first sample collected contained almost 10 times the amount of plastic than would be collected in a typical ocean sample. The plastic found in the Chesapeake Bay samples included bits of bags, sheeting, fishing line and microbeads, which are small plastic scrubbers found in face wash, toothpaste and cleaning products. Microbeads in particular are a major source of microplastics pollution worldwide. They are small enough to bypass water treatment systems’ filters (过滤器) and end up in waterways. Scientists warn that chemicals and toxins (毒素) absorbed by microbeads and other microplastics could be passed on to organisms who mistake them for food and eat them, and could then be passed up higher and higher on the food chain, eventually reaching humans.
1.What is the second paragraph mainly about?
A. The description of the trawl.
B. The basic data of the water samples.
C. The process of collecting water samples.
D. The introduction of Trash Free Maryland.
2.What does the underlined word “They” in the last paragraph refer to?
A. Bits of bags. B. Chemicals.
C. Microbeads. D. Micropiastics.
3.How does the author prove plastics pollution can be harmful to people’s health?
A. By analyzing the data. B. By making comparisons.
C. By giving some examples. D. By referring to scientists views.
4.What’s the author’s purpose in writing this passage?
A. To explain some new scientific terms to people.
B. To let people learn more about plastics pollution.
C. To urge governments to make environmental laws.
D. To tell people some new findings in scientific research.
