Ⅰ.阅读理解
Rubbish from the shipping lanes(航道) frequently washes up on UK beaches.Occasionally dangerous chemical containers appear prompting local beach collapses.The incident on the East Sussex coast on 27 August became even more serious.
Although media reports focused on the beach at Birling Gap,air pollution monitors(监视器) tell us that the affected area was much bigger.An obvious sharp rise in ozone(臭氧) was found on Eastbourne sea front at 4:45 pm and then about 30 minutes later at Lullington Heath,8km to the west and 5km inland from Birling Gap — an area of over 40 square km.
Around 150 people received hospital treatment but the symptoms(症状) varied with the different concentration(浓度) of ozone discovered,suggesting that the gas was not actually ozone or that it was ozone plus something else.
The 1986 Chernobyl nuclear incident prompted the development of computer systems to observe air pollutants.These models use weather models to trace where the wind takes the polluted air.They can also be run backwards to see where it came from.During the previous 24 hours,the polluted air had traveled from the middle of the English Channel,and came ashore east of Eastbourne,then floated west along the coast before heading out to sea again.The source was somewhere along this path.
Smokes from traffic and ships are unlikely to be the cause since they are present all the time and such an incident has never occurred before.Other ideas include leaks from goods on a ship.
