中新社广州2月20日电 （记者 杨薇）“事实上珠三角是在中国最早出现含氮有机颗粒物的地区。”广东著名灰霾专家吴兑20日对中新社记者披露，在珠三角地区，这种物质在细颗粒物PM2.5中就占了近三成，且近十年来占比增长速度较快，并和港澳地区相互产生影响。

China news agency guangzhou February and report (Reporter YangWei)"In fact the pearl river delta is China's first appeared in nitrogen organic particles area."Guangdong famous grey haze experts WuDui twenty days to China news agency reporter disclosure,In the pearl river delta region,This substance in fine particles PM2.5 in accounting for nearly thirty percent,And for the past ten years than the growth rate faster,Hong Kong and Macao and influence each other.

　　吴兑所指的含氮有机颗粒物，正是前不久中国科学院公布的“大气灰霾追因与控制”专项课题组的最新研究结果。在京津冀雾霾天气的专项研究中，专项组检出了大量含氮有机颗粒物，该物质是洛杉矶上世纪光化学烟雾的主要成分之一，在那次污染事件中，共有800余人丧生。

WuDui referring to nitrogen organic particles,It is recently released by the Chinese academy of sciences"Atmospheric gray haze chase for and control"The latest research results of the special group.In beijing-tianjin-hebei fog haze weather special study,The special group of detection of nitrogenous organic particles,This matter is Los Angeles last century is one of the major components of photochemical smog,In the pollution incident,There are more than 800 people were killed.

　　石油挥发物(碳氢化合物)和氮氧化物，在强烈阳光紫外线照射下会变成颗粒状，进而形成含氮有机颗粒物，它是光化学烟雾产生危害的重要二次污染物，其“主谋”为机动车、燃煤等。

Oil volatile(hydrocarbon)And nitrogen oxides,In the strong sunlight uv rays will become granule,Then forms nitrogen organic particles,It is photochemical smog harm important secondary pollutants,the"counselor"As the motor vehicle/Coal, etc.

　　吴兑表示，从2003年开始，珠三角就已受到世界各地专家研究“关照”。他强调，含氮有机颗粒物的产生跟经济发展有密切关系，越是经济发达的地区，越容易先出现，“含氮有机颗粒物随着季风方向的不同在珠三角和港澳地区之间相互输送，相互影响，因而不仅是珠三角，港澳地区也存在这种物质。”

WuDui said,Starting from 2003,The pearl river delta is has been all over the world experts research"attention".He stressed that,The production of nitrogenous organic particles with economic development has a close relationship,The more developed economies,The easier it is to appear first,"Nitrogen organic particles with monsoon direction in the pearl river delta and Hong Kong and Macao regions different between delivery,Influence each other,So not only is the pearl river delta,Hong Kong and Macao regions also has this kind of material."

　　据吴兑介绍，含氮有机颗粒物对人体的呼吸系统、循环系统均有伤害，但广东近年来一直在治理空气，也取得了成效。

According to WuDui introduced,Nitrogen organic particles on human respiratory system/Circulation system were hurt,But guangdong in recent years has been in control air,Also has yielded results.

　　广东省环保厅去年底曾宣布，可挥发性有机物被列入未来8年广东空气污染治理的防控重点，率先在中国将其排放纳入总量控制，且逐步禁止销售和使用高挥发性油漆和涂料。

Guangdong province HuanBaoTing announced late last year,Volatile organic compounds can be included in future eight years guangdong air pollution prevention and control of the key,Took the lead in the China will its emissions into the total amount control,And gradually banned the sale and use of high volatile paint and coatings.

　　记者20日从广东环保厅获悉，2006年起，广东开始对监控大气污染物的数据进行统计，2006年广东珠三角PM2.5的年平均浓度是每立方米49微克，到2012年时已下降到42微克。目前广东正在制订珠三角第二阶段清洁空气计划，以控制PM2.5和臭氧为重点，力争到2015年珠三角PM2.5和臭氧污染得到初步控制，到2020年珠三角空气质量明显改善。

Reporters learned from guangdong HuanBaoTing twenty days,Since 2006,Guangdong began to monitor air pollutants for statistical data,In 2006, guangdong pearl river delta of PM2.5 annual average concentration is per cubic meter of 49 micrograms,The year 2012 has fallen to 42 micrograms.Guangdong pearl river delta is at present for the second stage clean air plan,To take control of PM2.5 and ozone as the focal point,Strive for to 2015 pearl river delta PM2.5 and ozone pollution get preliminary control,By 2020 the pearl river delta air quality improved obviously.

　　此外，广东今年将继续加强与港澳之间关于大气监控污染物方面的合作，目前在粤港两地建立了19个监控网，今年还将澳门加入珠三角监控网中，届时能实现三地联网监控。（完）

In addition,Guangdong this year will continue to strengthen and between Hong Kong and Macao on atmospheric monitoring pollutant cooperation,At present in the two governments set up 19 monitoring network,This year will also join in the pearl river delta monitoring network,The three can realize network monitoring.(finish)
