Original title: governance solutions | Chen Jining: air quality in some cities "rebound"
Beijing News News (reporters Wang Shu) earlier today, entrusted by the State Council, Chen Jining to the national people's Congress, Minister of environmental protection of the State Council on 2015-State of the environment and environmental protection target completion of the report, he said, "in 2015, further improving national environmental quality, environmental pollution and ecological damage, and high environmental risks remain serious problems."
For air quality situation, Chen Jining introduced said: national 338 a to level and the above city in the, has 73 a city standard, accounted for 21.6%; excellent days proportion 76.7%, heavy degrees and the above pollution days proportion 3.2%; fine particles real (PM2.5) annual concentration 50 μg/cubic metres, exceeded 42.9%, can inhalation particles real (PM10) annual concentration 87 μg/cubic metres, exceeded 24.3%; II oxidation sulfur (SO2), and nitrogen dioxide (NO2), and ozone (O3) , Carbon monoxide (CO), annual average concentration of 25 mg/m respectively, 30 mg/m, 134 mg/m, 2.1 mg/m3, standard.
Said Chen Jining, current trends in air quality is improving, but still high-polluting, high incidence of smog-prone parts of the winter. The first batch of 74 cities in implementing the new ambient air quality standards, from 2013, air quality days last year for 71.2%, and 10.7% heavy pollution days and above at 4.1%, down 4.6%; average concentrations of fine particles 55 micrograms/m, 23.6%. In 2015, 338 and above city average annual concentration of inhalable fell 7.4%, 78.4% of the city's air quality continues to exceed, there are 45 cities average annual concentrations of fine particles exceeded more than 1 time. Jing-Jin-JI area of severe pollution days and above at 10%, down 7%, but heating season average concentrations of fine particles grew 9.6% (Beijing 75.9%), is affected by many factors, November-December 3 heavy pollution weather.
"Particulate matter pollution as the main factor, increasing ozone pollution." Said Chen Jining, and inhalable fine particles as a primary pollutant exceeds the number of days, total exceeded the number of days more than 80%. Total ozone as the primary pollutants exceeding the number of days of 16.9%. Annual average sulphur dioxide concentrations exceeding the city, fell from 22.6% in 2010 to 2015, 3.3%, area total land area ratio of acid rain, by the historical peak of around 30% to 8.8%.
Chen Jining stressed that another characteristic of the current air quality is "regional imbalance, some cities have rebounded." Pearl River Delta Air quality improvement was the highest region average concentration of fine particles is 34 μg/m3, standard for the first time. Zhengzhou, Jinan, Urumqi, fine particulate matter concentrations in 2014 fell after 2015 and bounce and there are 70 cities respirable particulate matter concentrations do not fall but rise.
Original title: governance solutions | Chen Jining: will launch a national soil pollution investigation
Beijing News News (reporters Wang Shu) took place shortly before the external "poison" event, land pollution, sounded the alarm. Earlier today, entrusted by the State Council, Chen Jining to the national people's Congress, Minister of environmental protection of the State Council on 2015-State of the environment and environmental protection target completion of the report. When it comes to soil conditions, he said "total points exceeded the rate of soil 16.1%, mild, mild, moderate, and severe pollution levels, respectively, 11.2% and 2.3%, and 1.1%, bit rate to 19.4% in cultivated land. The Yangtze River Delta, the Pearl River Delta, parts of Northeast old industrial base and soil pollution problems are more prominent, excessive heavy metals in soils in the southern area in the Southwest, the range ".
When it comes to the next work plan, he said the forthcoming implementation of the ten rules. Launch a national soil pollution in detail, with a focus on agricultural land and land for construction, the implementation of classification management and control. Completed state-controlled monitoring of soil environment quality level setting, soil environment database. Healthy soil pollution prevention-related standards and technical regulations, promoting governance and restoration demonstration pilot.

原标题：政解|陈吉宁：部分城市空气质量“有所反弹”
新京报快讯(记者 王姝)今天上午，受国务院委托，环保部部长陈吉宁向全国人大常委会作《国务院关于2015年度环境状况和环境保护目标完成情况的报告》，他表示，“2015年，全国环境质量进一步改善，但环境污染重、生态受损大、环境风险高等问题仍然突出”。
针对空气质量情况，陈吉宁介绍说：全国338个地级及以上城市中，有73个城市达标，占21.6%;优良天数比例76.7%，重度及以上污染天数比例3.2%;细颗粒物(PM2.5)年均浓度50微克/立方米，超标42.9%，可吸入颗粒物(PM10)年均浓度87微克/立方米，超标24.3%;二氧化硫(SO2)、二氧化氮(NO2)、臭氧(O3)、一氧化碳(CO)年均浓度分别为25微克/立方米、30微克/立方米、134微克/立方米、2.1毫克/立方米，均达标。
陈吉宁表示，目前空气质量总体呈改善趋势，但污染程度仍较高，部分地区冬季雾霾天气频发高发。首批实施新环境空气质量标准的74个城市，与2013年相比，去年空气质量优良天数比例为71.2%，提高10.7个百分点;重度及以上污染天数比例为4.1%，下降4.6个百分点;细颗粒物平均浓度为55微克/立方米，下降23.6%。2015年，338个地级及以上城市可吸入颗粒物年均浓度同比下降7.4%，有78.4%的城市空气质量仍然超标，有45个城市细颗粒物年均浓度超标一倍以上。京津冀地区重度及以上污染天数比例为10%，同比下降7个百分点，但采暖期细颗粒物平均浓度同比增长9.6%(北京增长75.9%)，受多种因素影响，11-12月出现3次重污染天气。
“颗粒物为主要污染因子，臭氧污染问题日益增多”。陈吉宁说，细颗粒物和可吸入颗粒物作为首要污染物的超标天数，占总超标天数八成多。臭氧为首要污染物的占总超标天数的16.9%。二氧化硫年均浓度超标城市比例，由2010年的22.6%下降到2015年的3.3%，酸雨区面积占国土面积比例，由历史高峰值的30%左右降至8.8%。
陈吉宁强调，目前空气质量的另一个特点是“区域不平衡，部分城市有所反弹”。珠三角空气质量改善幅度最大，区域细颗粒物平均浓度为34微克/立方米，首次达标。郑州、乌鲁木齐、济南细颗粒物浓度在2014年同比下降后，2015年又有反弹;同时，还有70个城市可吸入颗粒物浓度不降反升。
原标题：政解|陈吉宁：将启动全国土壤污染状况详查
新京报快讯(记者 王姝)前不久发生的常外“毒地”事件，给土地污染敲响了警钟。今天上午，受国务院委托，环保部部长陈吉宁向全国人大常委会作《国务院关于2015年度环境 状况和环境保护目标完成情况的报告》。谈到土壤环境状况时，他介绍说“全国土壤总的点位超标率为16.1%，其中轻微、轻度、中度和重度污染点位比例分别 为11.2%、2.3%、1.5%和1.1%，耕地土壤点位超标率为19.4%。长三角、珠三角、东北老工业基地等部分区域土壤污染问题较为突出，西南、 中南地区土壤重金属超标范围较大”。
谈到下一步的工作计划时，他表示即将出台实施《土十条》。启动全国土壤污染状况详查，以农用地和建设用地为重点，实行分级分类管控。完成土壤环境质量国控监测点位设置，建立土壤环境基础数据库。健全土壤污染防治相关标准和技术规范，推进治理与修复试点示范。
