Can scientist answer the question ""what concentration of gas molecules cause a visible brown haze in the air""
Answer (1)
Yes, scientists can answer this question, but it's not just about a specific concentration of gas molecules. The brown haze you see in the air is often caused by a mixture of air pollutants, primarily nitrogen oxides (NOx) and volatile organic compounds (VOCs), which react in the presence of sunlight to form ground-level ozone (a key component of smog).The concentration of these gases needed to cause a visible brown haze depends on many factors, such as temperature, sunlight, and wind conditions. Typically, high levels of nitrogen oxides and VOCs are found in areas with heavy traffic or industrial activity. The "brown haze" effect is often noticeable when the concentration of these pollutants is high enough to form enough ozone that it can be seen.So, while scientists can measure concentrations of these gases, predicting the exact concentration that will cause visible haze is more complex and depends on environmental conditions.
