One long-distance flight consumes fuel which a car uses in several years' time, but they cause the same amount of pollution. So, some people think that we should discourage non-essential flights, such as tourist travel, rather than limit the use of cars. To what extent do you agree or ...
Existing methods for fine-scale air quality assessment have significant gaps in their reliability. Purely data-driven methods lack any physically-based mechanisms to simulate the interactive process of air pollution, potentially leading to physically inconsistent or implausible results. Here, we report a...

Air pollution is a serious environmental problem that has attracted much attention. Air quality prediction can provide useful information for urban environmental governance decision-making and residents’ daily health control. However, existing research methods have suffered from a weak ability to capture ...
Smoke increased a little more steeply and peaked at about 450 micrograms in 1890. During the 20th century, both smoke and sulphur dioxide took a dramatic drop, although there was a fluctuation within the fall.It is obvious that air pollution was considered as a bigger problem in the early ...

aIn June 1995, instead of adopting internationally accepted benchmark index for pollution[vague], it set up the Air Pollution Index as an indicator to pollution levels, both "General" and "Roadside". 在1995年6月,而不是采取国际上被接受的基准索引为污染(隐晦),它设定了空气污染索引作为显示对污染...

The ratio of PM2.5 to PM10 decreased by about 5.4%, indicating that the decrease in PM2.5 contributed more to the air pollution caused by particulate matters. The results were consistent with the focus of the “declare war on pollution” policy of the government of China [103,104], which ...
