What trees are responsible for smog?

In the south, trees with large leaves that can secrete mucus are particularly effective at absorbing dust, such as locust trees, camphor trees, oleanders, etc. In the north, poplars and yews absorb haze dust relatively well.

Haze is a combination of fog and haze. Smog is common in cities. In many areas of China, fog is combined with haze as a disastrous weather phenomenon for early warning and forecasting, collectively referred to as "haze weather".

Haze is the result of the interaction between specific climatic conditions and human activities. Economic and social activities of high-density populations will inevitably emit large amounts of fine particulate matter (PM 2.5). Once the emissions exceed the atmospheric circulation capacity and carrying capacity, the concentration of fine particulate matter will continue to accumulate. At this time, if affected by calm weather, it is easy to cause large-scale pollution. Scope of haze.

The composition of smog: sulfur dioxide, nitrogen oxides and inhalable particulate matter are the main components of smog. The first two are gaseous pollutants, which combine with fog to make the sky instantly gray.
