In between all the measures to battle the severe air pollution in Delhi,India,there’s one more option-a bar that has”pure air”.
Founded by Aryavir Kumar,Oxy Pure,Delhi’s first-ever oxygen bar,offers 15 minutes of 80-90 percent pure oxygen,costing Rs 299($4.2).Customers are given a lightweight tube for oxygen intake.The device(装置)is placed near the customer’s nostrils(鼻孔)through which they are advised to breathe in the oxygen.
The bar also offers its customers several aromas(气味)to go with oxygen,including lemongrass,cherry and more.According to the aroma people choose,each session promises to improve sleep patterns and digestion,cure headaches,and even claims to work as a treatment for depression.
Bonny Irengbam,a senior sales assistant at the bar,said,”Some people,who try it for the first time,will feel relaxed and fresh.But only people who do this regularly will get real benefits.By regularly,I mean once or twice a month.We don’t encourage back-to-back sessions,as increased levels of oxygen in the body can make a person dizzy.”
Dr.Rajesh Chawla,a senior doctor at the Indraprastha Apollo Hospital,said,”Even if you breathe in the so-called pure oxygen for two hours in a day,you will go back to breathing the polluted air for the rest of the 22 hours.The concept is purely money-driven.”
Recalling the first few months of the bar,Irengbam admitted that people were sceptical. “Many people criticised,saying we were selling air.Others were simply scared to breathe through the tube.”
Irengbam said the bar saw a significant rise in the number of customers two to three days after Diwali,an Indian festival mainly celebrated by fireworks and lights,as the pollution levels were high.

The microplastics(微型塑料) problem in the oceans has made its way to sea turtles in a big way. A new study has found microplastics in the stomach of every single turtle they tested—a total of 102 sea turtles.
The researchers tested more than 100 sea turtles from all seven kinds and three different oceans, and they were looking for man-made things less than 5 mm long. The most thing the team found were fibers (纤维), which most likely came from clothing and fishing equipment.
“The influence of these particles (颗粒) on turtles is unknown,” said Emily Duncan. “Their small size means they can pass through the stomach without causing a problem, as is frequently reported with larger plastic pieces.”
The researchers found more than 800 man-made particles in the turtles, but since they only tested part of the stomach, they believe the total number of particles could be 20 times higher. They don't know how the turtles take in the particles, but they think they are from polluted seawater and polluted plants.
Professor Brendan Godley said that eating microplastics isn't the biggest problem to sea turtles at the moment, but it is a clear sign that we need to do a better job watching global waste.
This turtle study shows that we need to reduce the amount of plastic waste, so we can keep clean and healthy oceans for future people.

One e-toy for every person on Earth — that’s the surprising amount of electric trains, talking dolls, and other children’s devices thrown away every year. People usually consider electronic waste from computers, smartphones, and TVs to be e-waste, but they may not realize that “nontraditional” e-waste materials like power tools, LED lights, USB cables and countless other similar, also need special recycling. In all, people across the world throw out about 9 billion kilograms of e-waste commonly not recognized as such by people.
This “invisible e-waste” is the main focus of the sixth annual International E-Waste Day on October 14, organized by Waste Electrical and Electronic Equipment (WEEE) Forum. According to the findings, for example, the total weight of all USB cables thrown away every year equals 6 Eiffel Towers. Meanwhile, if all this invisible electronic waste were packed into trucks, it could fill half a million 40-ton trucks, enough to cause a long traffic jam covering about 3, 504 miles.
“People are familiar with common e-waste. But many invisible e-waste are ignored. How to have them recycled remains a big problem.” Pascal Leroy, Director-General of the WEEE Forum, said in a statement. Pascal Leroy asks that instead of throwing them away, people should take it to the local recycling facility. He says that a lot of electronic waste is right around us, and we need to raise awareness about this issue. He also refers to past campaigns that successfully made people more aware of plastic pollution and believes the same can happen with e-waste awareness.
【小题1】Which of the following belongs to the “invisible e-waste”?A.Smartphones. | B.Computers. | C.Talking toys | D.USB cables. |
A.To make the number exaggerated. | B.To show the destination of the wastes. |

A.Recycle or Not? That’s a Problem |
B.New Electrical Wastes that Go Unnoticed |

Graph 2: Chinese National Standard
API Values | Levels of health concern | Colors |
When the API is in this range: | ...air quality conditions are: | ...as symbolized by this color: |
0 to 50 | Very good | Blue |
51 to 100 | Good | Green |
101 to 150 | Slight pollution | Yellow |
151 to 200 | Moderate pollution | Orange |
201 to 250 | Medium pollution | Red |
251 to 300 | High pollution | Purple |
301 to 500 | Hazardous | Brown |
Notes:
**API stands for Air Pollution Index(指数).
**Particulate matter (PM10) is a major component of air pollution that threatens both our health and our environment. It consists of very small liquid and solid particles floating in the air.
**Sulfur dioxide(SO2) acts as an acid.Inhalation(吸入) results in labored breathing, coughing, or a sore throat and may cause permanent lung damage.
