Shanghai's best fresh-air zone vanishing?   

探訪淀山湖：上海“最清潔空氣”正在消失？

自6月27日上海環(huán)保部門開始發(fā)布十個監(jiān)控點的PM2.5(可入肺顆粒物)值，原本擁有“最清潔空氣”的淀山湖空氣污染指數(shù)卻“意外走高”，PM2.5值一直處于高位，一度成為上海數(shù)值最高的地區(qū)。

Shanghai (CNS) -- Dianshan Lake, the largest freshwater lake in Shanghai and the source of the Huangpu River, is suffering from severe pollution and the region no longer has air as fresh as before. A reporter from CNS made a visit to the lake on Thursday.

The PM2.5 readings at Dianshan Lake in Qingpu District ranked the highest among all the 10 monitoring spots on June 27, which aroused public attention. Experts surmize that what is contributing to the negative index results are ocean breezes from the east carring an accumulation of particles into the lake area.

Eighty-year-old Xiang Keding lives adjacent the monitoring spot several hundred meters away from the lake, and he said:"It is obvious the air is not as good as before, as too many houses and small-sized factories are crowding in here."

Local fisherman Liu Jianzhong said he can only harvest a few kilograms of fish daily now, a quarter of the take in the old days.

There is no official explanation as to why PM2.5 readings here in Shanghai city have hit record highs.
