Nitric oxide (NO) pollution can have several negative impacts on the environment and human health. Let`s take a look at each of the given options to understand how they are related to NO pollution.
1. Leaf spotting in plants: Nitric oxide pollution can cause damage to plant tissues, leading to leaf spotting. Nitric oxide reacts with other compounds in the atmosphere to form nitrogen dioxide (NO2), which can cause oxidative stress and injury to plants.
2. Bronchitis-related respiratory problems in humans: Nitric oxide is a major component of air pollution, especially in urban areas where it is emitted from vehicle exhaust and industrial processes. Inhalation of NO can irritate the respiratory system, leading to bronchitis-related respiratory problems such as coughing, wheezing, and shortness of breath.
3. Production of corrosive gases through photochemical reaction: Nitric oxide reacts with other pollutants, such as volatile organic compounds (VOCs), in the presence of sunlight to form nitrogen dioxide (NO2) and other corrosive gases like ozone (O3). These gases contribute to the formation of smog and can corrode metals and damage infrastructure.
4. Silicosis in humans: Silicosis is a lung disease caused by inhaling silica dust,
