看了一下， 看完了， 说几句
1。 发展工业 必然带来 人们 生命 生活 环境 的污染， 地构资源的破坏，
2。这是个矛盾，必须解决
3。国家 政府 的整体规划 法规的制定和执行 是个关键
4。总理 总书记， 尤其 邓 胡 赵 李 江 朱 胡 温 习 李 等人 未尽到责任，失职
5。柴静 捅出这个问题，是一件好事儿，应该得到支持肯定赞许
6。柴静 不是个学者 更不是个科学家，她的结论并非全部正确和完整，可以应该指出评判，但 不必求全责备
7。粗醅非酒乃酒母， 酒从醅出，喝酒莫忘醅
（题外话： 柴的这个片子 可能会得到 诺贝尔提名，至少；至多是嘛，你懂的～）
8。文化 知识 科学 是指导， 这个 认知和执行需要有个过程
9。利益 利润 成本 贪腐 是根基所在
10。所谓近30年来 中国在人类资源 地理环境 生活空间方面 的确是 越来越糟
为了 GDP 几乎无所不用其极
11。假冒伪劣毒 食品 饮用水 灌溉农田的水 蔬菜水果肉类蛋类，，，，，有法不依，执法不力，虚张声势
12。为了你我他她的今天 和 子孙后代的明天，我们真的需要关注和 对环境保护做点儿什么

Atmospheric particulate matter – also known as particulate matter (PM) or particulates –
is microscopic solid or liquid matter suspended in the Earth's atmosphere.
Subtypes of atmospheric particle matter include ：
suspended particulate matter (SPM),
respirable suspended particle(RSP; particles with diameter of 10 micrometres or less, i.e. PM10),
fine particles (diameter of 2.5 micrometres or less， i.e. PM2.5),
ultrafine particles, and soot.
The IARC and WHO designate airborne particulates a Group 1 carcinogen.
Particulates are the deadliest form of air pollution due to their ability to penetrate deep into the lungs
and blood streams unfiltered, causing permanent DNA mutations, heart attacks, and premature death.[4]
In 2013, a study involving 312,944 people in nine European countries revealed that
there was no safe level of particulates and that for every increase of 10 μg/m3 in PM10,
the lung cancer rate rose 22%.
The smaller PM2.5 were particularly deadly, with a 36% increase in
lung cancer per 10 μg/m3 as it can penetrate deeper into the lungs.[5]

Air pollution and lung cancer incidence in 17 European cohorts: prospective analyses from the European Study of Cohorts for Air Pollution Effects (ESCAPE)
Article InfoSummary
Background
Ambient air pollution is suspected to cause lung cancer. We aimed to assess the association between long-term exposure to ambient air pollution and lung cancer incidence in European populations.
Methods
This prospective analysis of data obtained by the European Study of Cohorts for Air Pollution Effects used data from 17 cohort studies based in nine European countries. Baseline addresses were geocoded and we assessed air pollution by land-use regression models for particulate matter (PM) with diameter of less than 10 μm (PM10), less than 2·5 μm (PM2·5), and between 2·5 and 10 μm (PMcoarse), soot (PM2·5absorbance), nitrogen oxides, and two traffic indicators. We used Cox regression models with adjustment for potential confounders for cohort-specific analyses and random effects models for meta-analyses.
Findings
The 312,944 cohort members contributed 4,013,131 person-years at risk. During follow-up (mean 12·8 years), 2095 incident lung cancer cases were diagnosed.
The meta-analyses showed a statistically significant association between risk for lung cancer and PM10 (hazard ratio [HR] 1·22 [95% CI 1·03–1·45] per 10 μg/m3).
For PM2·5 the HR was 1·18 (0·96–1·46) per 5 μg/m3. The same increments of PM10 and PM2·5 were associated with HRs for adenocarcinomas of the lung of 1·51 (1·10–2·08) and 1·55 (1·05–2·29), respectively. An increase in road traffic of 4000 vehicle-km per day within 100 m of the residence was associated with an HR for lung cancer of 1·09 (0·99–1·21).
The results showed no association between lung cancer and nitrogen oxides concentration (HR 1·01 [0·95–1·07] per 20 μg/m3) or traffic intensity on the nearest street (HR 1·00 [0·97–1·04] per 5000 vehicles per day).
Interpretation
Particulate matter air pollution contributes to lung cancer incidence in Europe.
