最近查看空气污染指数都会发现这样的现象。可印尼和新山的空气都远好过本地呀。是否因为本地人口密度超高，常年焚烧垃圾，本地产生的空气污染就已经非常严重了，再加上近两个月本地人的鬼月烧纸等行为造成的本岛污染指数远高过周边地区？
按理说烧纸都在烧，为啥北部的数据一枝独秀呢？
风向啊，大侠。
还常年烧垃圾空气污染。。。
这种智商怎么出来混的。
每天都烧垃圾，然后存起来集中在几天释放污染
整个7月每天都烧纸，然后存起来集中到一个地方释放污染。
这人脑子有病。
新加坡自己的污染的确比较严重的。西部的化工厂，东部的飞机场一起飞就是一顿油耗。北部的轮船码头一开动就是几顿油耗。还有各种汽车。工厂。 550万人口的废气。 都密集在700平方公里什么。
看着这张图还讲什么风向，这可不是智商低的问题，是根本就不想说实话，居心叵测。
现在这么严重的空气污染，确实是印尼烧芭造成的。
风是西南风，苏门答腊森林大火的烟雾，直接飘来新加坡，印尼的观测点太少，不能说明真实情况。
这种铺天盖地的烟烧冥纸是很难达到要求的。得印尼人去烧他们的老底， 配上西南季风，才能在新加坡看到这种奇观。
这是现在的指数。烟雾不飘去新山吗？
这种东西要看统计值，瞬时值仅供参考，而且取样点不同，数值也不同，楼主贴图用的这个网站，现在新加坡的数据已经全面低于100了，西部93反而成了最高，其余方向都低于70.
可是新加坡nea的数据，北部还是100多一点。
今天烟雾去KL了。。。
以上是耶鲁的报告（http://epi.yale.edu/），是綜合排名。按一下国名，可以看到此国的各个单项排名。
新加坡在废水处理上做得很好，空气质量上还有待进步。上联合国的网站：世界污染现状与治理，也可以大概了解新加坡的空气质量排名。
（最好是看城市与城市比较，还没找到。）
楼主人呢，出来看看现在的数据吧，看问题不能只盯住某个瞬间.
水，是自家的水，容易控制；
空气质量，除了自己努力，也得靠邻国配合。
都如去年那样，有大半年在吸邻国的烟灰，全年的空气平均值，怎么能好？
印尼这种流氓国家为啥没人治得了？
因为是流氓国家。。
楼主的脸被打的啪啪的。。。。
世界卫生组织的数据，总数是3000个城市，我缩减了一下，对同一国来说，是把数据较好的城市删除了（简单认为其人口不多），我本意是要找人口拥挤，经济发达的城市来跟新加坡比较。一开始还会去看一下城市情况，整理到后面有点没了耐性，只删好的数据，可能有一些偏颇，仅供参考。详情可看：Ambient (outdoor) air pollution database, by country and city

这么多天过去了风都是吹西北的，新加坡附近的空气任然是非常的好啊！！！
今天北部地区的空气的确不咋地，我觉得和烧纸有点关系。城市越来越密集，烧纸这种陋习真的是要改改了。
我们在讨论什么？应该不是讨论是本地的空气好，还是巴淡岛的空气好。而是讨论本地的较差空气是本地自己造成的，还是受到印尼的烧芭影响。
答案是肯定的：只要印尼的火还在烧，只要地球不发生倒转（季风改变），本地空气质量就会受印尼烧芭影响。
怀疑者总是拿空气观测图来说事，我也就来说一说吧。
我前面说，数据与取点的位置有关。从图上看，印尼烧芭区域并没有给出数据，整个苏门答腊岛，空气好得很，是事实吗？
再说新加坡周围，与新加坡地理位置相近，也会受印尼影响的kukup, Telok Kreang等等大片地区，没有数据，北部的柔佛和Pasir Gudang数据和新加坡相近 ,离印尼火点远一些，这两个区域的烟雾，比新加坡稀薄一些也是正常。拿更远的benut或巴淡岛来说事，就没有什么意义了。
上环境局网站，可以查到PSI的历史数据：[color=#0388BA ]Historical PSI Readings
兀兰那边数值有时偏高，应该与工业区有关，如果裕廊岛出数据，应该更不好。
辛苦了，提供这么多数据来支持。其实，楼主自己胡扯了一通，被打脸之后早就弃贴了。

前面的帖子不见了？
印尼常年都在烧笆，烟雾如果飘到本区域来就会对整个区域产生影响，风是不会跳跃或蛇形移动的。一个地方空气的好坏即受外来影响也有本身的因素。新山71和171并不是接近的数字。look5的贴的那些数字更无意义，豪无可比性。最近有时常常看到一坐楼下就有几处烧纸的，有的是在圆形水泥池中烧的，产生大量的黑烟。在一个人口密度如此高的地方，集中这么多工业，环保再做的如此的“优秀”，那还能希望多好的空气呢？受印尼的影响在天数和程度方面是相对的，自身的因素才是绝对的。为什么简单的问题要弄这么复杂，是心态，是你脸上有块污迹你自己不愿意承认罢了。
我也不喜欢人烧纸，特别是以前住hdb，楼下烧纸的一堆接着一堆，很烦人。但是这是传统习俗，很难改变，何况也就是七月的月头月中月尾集中烧一点而已。这次只不过正好和烧吧污染撞车了。
“印尼常年都在烧笆”
这是误解。印尼分雨季和旱季两个季节，上半年雨季，下半年旱季，当地人只有在旱季才烧芭。所以，对比本地去年上半年和下半年的空气指数，就能回答楼主的质疑。
“风是不会跳跃或蛇形移动的。一个地方空气的好坏即受外来影响也有本身的因素。新山71和171并不是接近的数字。look5的贴的那些数字更无意义，豪无可比性。” “受印尼的影响在天数和程度方面是相对的，自身的因素才是绝对的。”
空气是流动的，数据则可以跳跃地取，同一地点，在上风口取值，还是下风口取值，数据就可以天差地别，这也是为什么楼主的第一个图上，印尼的火源地区空气指数也能如此好。楼主发帖的主题应该是否定印尼烧芭对本地空气的影响，现在是承认了烧芭对新加坡的影响，还是坚持不承认呢？如果发帖的标题换一下，重点不在否认印尼烧芭的影响，只是批评新加坡空气不好，我不会接话；如果不是有人闭目塞听，坚持不承认印尼烧芭对本地空气的破坏，我也不会有兴趣去了解本地的空气质量，到底是处于怎样的水平。我只是要说明一个简单的事实 : 楼主发帖时新加坡的指数过百，确实是印尼烧芭造成的。我的数据，是要还原新加坡在不受烧芭影响时，空气质量的真实情况，并无粉饰功能。数据能说话，看懂它就有意义了。另外，既然已经了解一个地方空气的好坏即受外来影响也有本身的因素，就不该拿新山来苛求新加坡，新山是怎样的人口密度和工业水平？有可比性吗？我罗列出许多城市的数据，就是要大家拿人口密度相近，发达程度相近的城市来和新加坡比较，这样才较为客观。取值的时间点不同，是即时的？3小时的？还是24小时的？也会影响数值。
楼主发的那个网站，现在新加坡五个取样点都是30多，烧芭的影响暂时过去了，七月也过去了，如果前些天破百是因为本地工业交通啥影响的，不可能这么短时间就回复30多。
所以说，要么就是烧芭，要么就是七月烧纸，或者两者都有影响。
世界空气污染：实时空气质量指数地图 – AQICN.org是楼主提供的网站，我观察了1-2个小时，其间，新加坡的数据在不断地更新，而马来西亚的数据则一直没有变化。所以，我有理由怀疑，71和171不是同一时间点的数据，无可比性。就算71和171是同一时刻的数据，也只能说明新山比新加坡的空气要好，不能证明是有还是没有印尼烟雾的影响在里面。那么，我们怎么来判断171和71数据里有没有印尼烟雾的因素？很简单：1，凭我们自己的眼睛和鼻子。在这儿住久了，就知道怎样的空气是自制的，怎样的空气是舶来品； （本地拜神烧纸，常年都有，初一，十五等大日子，会更多一些，但其对空气指数的贡献没有那么大。）2，依据新闻报导，污染源的照片，风向；3，更精准一点，就是数据，拿本地即时的数据和历史的数据来比较。我想，凭以上3点来判断，应该已经足够。
