In Beijing and China
The haziness today is likely due to a high concentration of particulate matter in the air, such as pollution, dust, or smoke. These particles scatter sunlight and create a hazy appearance in the atmosphere.
Not likely. It's the chief source.
Increased levels of air pollution are positively correlated with higher rates of respiratory illnesses and allergies in urban areas. This hypothesis suggests that individuals living in areas with high air pollution are more likely to experience adverse respiratory health effects compared to those in areas with lower pollution levels.
Air pollution is typically invisible to the naked eye, but it can cause visible effects such as haze or smog. To accurately assess air pollution levels, specialized equipment like air quality monitors or sensors is needed. These devices measure the concentration of pollutants in the air, providing data on pollution levels.
No, the impact of air pollution can vary depending on various factors such as age, existing health conditions, and geographic location. Vulnerable groups like children, elderly individuals, and those with respiratory or cardiovascular diseases are more likely to experience severe health effects from exposure to air pollution. Additionally, individuals living in areas with high levels of pollution or near pollution sources may be more affected.

most likely that if the air pollution is not stoped the world will be a dark place in about 1oo years or so
The region of air with relatively many particles is called a high particle concentration area. These areas can be caused by pollution, dust storms, volcanic ash, or industrial activities. High particle concentrations can impact air quality and pose health risks to individuals exposed to them.
High altitude particulate pollution may be helping to reduce global warming.

The likely word is humidity (concentration of water vapor in the air).
