奥克兰空气不脏, 为什么但尼丁脏?

                                                世界卫生组织将有关新西兰城市空气质量不佳的数据已从其网站上删除。

　　此前，该组织网站上登出的数据显示，新西兰的大城市空气质量较澳大利亚的主要城市差，其中奥克兰的空气污染程度与东京相当。
　　目前的最新数据中，仅有Dunedin不符合世界卫生组织的空气质量安全指数，新西兰其他主要城市空气质量均在安全指数范围内。

可爱笨猪

世卫那伙人神经病，我都怀疑他们有木有来过nz，这日本 澳洲和我们都没有可比性。你说比不过北欧那几个小国家我还有情有可原。

应该是有收集空气数据, 粉尘之类的...

这和最后一片净土的口号不大和谐啊..

但尼丁除了一個巧克力工廠外還能有啥可能污染的？

冬天，丹尼丁比较冷，所以大家都用火炉烧木头的，所以空气中会有很多二氧化碳，二氧化硫，还有PM10（微小颗粒）。南岛大部分地方都有这个问题的，不是说工业少了，空气就好的。

北岛冬天相对暖和些，所以这个问题稍微好点

Dust from roads and "off the wheels" of vehicles is being blamed for much of central Dunedin's air pollution.

As a result, tighter controls could be placed on the movement of vehicles from construction sites.

The Otago Regional Council studied air quality in central Dunedin during 2010 to try to better understand air pollution around its Albany St monitor.


It found dust from roads and "off the wheels" of vehicles was a major contributor to air pollution in the area.

The site recorded pollution levels more than the National Environmental Standard (NES) limit of 50 micrograms per cubic metre on average six times. The NES allows its levels to be exceeded only once a year.

During 2010, from April to December, the level was passed 12 times, all during working week days.

Air quality scientist Deborah Mills, in a report to the council's natural resources committee yesterday, said most were just over the limit but that could have been because of the mild winter and therefore less domestic and industrial burning.

On high pollution days, coarse material dominated the sample but it was a combination of all sources that caused limits to be exceeded.

Chairman Stephen Woodhead said the study also showed that fine particles, which did the most damage to people's health, were below the NES.

Policy and resource planning director Fraser McRae said vehicle pollution had been thought of as from the exhaust pipe but this study showed what came "off the wheels" was of most concern.

While there might be less of a problem when the Forsyth Barr Stadium was completed, it was an issue with any construction site.

"It is a management issue. Vehicle movements around construction sites can be dealt with."

Environmental information and science director John Threlfall said the results showed controls around vehicle movements from construction sites needed to be dealt with during the consent process.

空气脏不脏和风大小也有关系的，惠灵顿空气在NZ最好也就是因为风最大。

牛A的弟弟

不是吧。。。

呵呵

二手小汽车闹得

个人觉得起起伏伏的城市比较脏,,

山下放个屁, 山上的就倒霉了.
