High-resolution urban air pollution mapping | Science - AAAS
2024年7月25日 · Fine-scale (~10 m to 1 km) air pollution gradients arise as primary emissions from unevenly distributed sources are diluted and undergo physicochemical transformation (1–3). The resulting intraurban variation in air pollution has important implications for …
Toward cleaner air and better health: Current state ... - Science
2024年7月25日 · Overall, PM air pollution ranks as the leading global risk factor for disease, resulting in an estimated 8% of total disability-adjusted life-years, and is associated with high systolic blood pressure, exacerbated risks from smoking, low birthweight, and short gestation (4).
The global threat from plastic pollution | Science - AAAS
2021年7月2日 · We highlight the complex characteristics of plastic pollution that evolve as it undergoes continuous weathering in the environment, and discuss potential large-scale and poorly reversible effects that could be triggered by continuing accumulation.
Air Pollution - Our World in Data
Air pollution is a health and environmental issue across all countries of the world but with large differences in severity. In the interactive map, we show death rates from air pollution across the world, measured as the number of deaths per 100,000 people in a given country or region.
How to Use the Air Quality Index | Scientific American
2023年6月7日 · Green is between 0 and 50 on this scale: in this category, air quality is good, with little or no risk from air pollution. From 51 to 100, the air quality is moderate, or yellow, which is...
Computational models to confront the complex pollution
2023年6月26日 · Global-scale models that describe the sources, fate and transport pathways and environmental concentrations of the footprint of pollution generated by plastic can play similar scientific and ...
“I am an air quality scientist”– Using citizen science to …
2021年10月1日 · We aimed to conduct a large-scale study that (i) characterised school children's exposure to air pollution (PM 2.5) during a typical school week using low-cost sensors and (ii) assessed the extent to which a citizen science approach to data collection could contribute to and impact the research development and outcomes. We hypothesised that ...
The pollution scale weighting model in water quality evaluation …
2022年2月1日 · Entropy weight model (EWM) is the most widely used objective weighting method for evaluating water quality. However, for the pollutant the data of which concentrate on the high polluted grade, EWM often neglects its importance, for its discrimination degree is low.
Chemical pollution in water: Scalable and intersectional …
2024年3月15日 · To understand chemical risks at scale (i.e., their probability of causing harm), we first need to define the hazard (how dangerous they are) and the exposure (i.e., the concentration and whether it is chronic or acute).
The role of citizen science in monitoring small-scale pollution events
2017年7月15日 · Citizen science can document small-scale pollution if robust methods are used. A monitoring system that integrates citizen and traditional science is proposed. Small-scale pollution events involve the release of potentially harmful substances into the marine environment.
