宮崎ハロー英会話のミニレッスン 42: PM 2.5
Today in Miyazaki the PM 2.5 is very bad. This is because air pollution is blown from China by strong west winds. In English, 汚染 is “pollution”. There are many different types of pollution, but here are three common types: air pollution (for example PM 2.5), water pollution (for example, dirty rivers and sea), and noise pollution (motorbike gangs!).
I hope the pollution is not bad where you live today!
