概括
北英格兰贫困的城市社区面临着更高的空气污染 (NO2) 和更不健康的绿地,特别是在工业城市. 需要有针对性的战略来减少排放和改善环境质量,以促进公共卫生.
科学领域:
- 环境健康 环境健康
- 城市规划是城市规划.
- 公共卫生研究 公共卫生研究
背景情况:
- 城市环境不平等是英国的重大公共卫生问题,特别是在工业化历史的地区.
- 暴露于空气污染和获得健康自然环境的差异加剧了健康不平等.
研究的目的:
- 检查空气污染 (NO2) 和绿地暴露在北英格兰不同类型的城市社区的空间分布.
- 为了比较主要的工业城市和较小的区域城市之间的环境负担,重点关注社会和种族差异.
主要方法:
- 利用下层超产区 (LSOA) 来分析英格兰北部十个城市的环境数据.
- 从健康资产和危险的获取和多重贫困指数中获得的雇员数据.
- 在不同贫困水平和城市类型中比较NO2度和正常化差异植被指数 (NDVI).
主要成果:
- 主要工业城市的贫困和种族多样性社区经历了较高的NO2水平 (在最贫困的LSOA中高出33%) 和较低的NDVI.
- 贫困地区的绿地往往靠近污染源,减少了健康益处;主要城市的83%的植被区域超过了世卫组织的NO2指南.
- 与主要城市相比,区域城市的污染较低,绿地分布更公平,社会差距较小.
结论:
- 城市形式和工业遗产显著影响环境不平等,不成比例地影响弱势群体.
- 仅绿色空间不足以缓解密集,交通繁忙的城市环境中的污染;结合绿色基础设施和减排的综合战略至关重要.
- 为了创造更公平,更健康的城市,实现国家和国际环境和健康目标,必须制定本地明智的战略.

Threats to Biodiversity
26.6K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Dimensions of Health and Illness

The factors influencing the health-illness continuum can be internal or external and may or may not be under conscious control. They are related to the following eight human dimensions, and each dimension is interrelated to one other.

Sampling Plans

Sampling is a crucial step in analytical chemistry, allowing researchers to collect representative data from a large population. Common sampling methods include random, judgmental, systematic, stratified, and cluster sampling.
Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...

Variation of Atmospheric Pressure
4.1K
Change in atmospheric pressure with height is particularly interesting. The decrease in atmospheric pressure with increasing altitude is due to the decreasing gravitational force per unit area as we move away from the surface of the earth.
Assuming the air temperature is constant at a given altitude and that the ideal gas law of thermodynamics describes the atmosphere to a good approximation, one can find the variation of atmospheric pressure with height.
Let p(y) be the atmospheric pressure at...

External and Internal Respiration
7.1K
External respiration occurs in the lungs, and it is the first step in the journey of oxygen inside the body. When we inhale, oxygen enters our lungs and diffuses across the thin alveolar membrane. The alveoli are tiny, air-filled sacs that provide a vast surface area for gas exchange. Oxygen in the alveoli has a higher partial pressure (105 mmHg) than in the adjacent pulmonary capillaries (40 mmHg), establishing a pressure gradient. As a result, oxygen molecules move from the alveoli into the...
