Getting regular tune-ups, changing oil on schedule, and inflating tires to the proper level can improve gas mileage and reduce emissions. Fuel up during the cooler hours of the day—night or early morning. This prevents gas fumes from heating up and producing ozone. Avoid products that release high levels of VOCs.

Photochemical smog is a mixture of pollutants that are formed when nitrogen oxides and volatile organic compounds (VOCs) react to sunlight, creating a brown haze above cities.

The measure of photochemical efficiency is made by meauring the amount of oxygen produced by leaves following exposure to various wavelengths. It is evident from these absorption and output plots that only the red and blue ends of the visible part of the electromagnetic spectrum are used by plants in photosynthesis.

By reducing energy consumption, choosing sustainable products and eliminating your exposure to chemicals, we can reduce pollution levels. If less gasoline, natural gas and electricity (power plants burn fossil fuels to generate electricity) are used, not only do your bills decrease but less pollutants are emitted.

Industrial smog comes from, clearly, industrial processes. It concentrates in urban areas and is formed from sulfur dioxide (mostly from burning coal), water droplets, and other particles such as dust. Photochemical smog is a mixture of all other pollutants, but mostly VOC's and nitrous oxides.

What is photochemical smog? Photochemical smog is a mixture of pollutants that are formed when nitrogen oxides and volatile organic compounds (VOCs) react to sunlight, creating a brown haze above cities. It tends to occur more often in summer, because that is when we have the most sunlight.

Photochemistry is the branch of chemistry concerned with the chemical effects of light. Generally, this term is used to describe a chemical reaction caused by absorption of ultraviolet (wavelength from 100 to 400 nm), visible light (400–750 nm) or infrared radiation (750–2500 nm).

Reduces Air Pollution As a result, greenhouse gas emissions, including carbon dioxide, nitrous oxide and methane are released into the atmosphere, increasing air pollution. ... Solar panels don't need to burn fossil fuels to generate electricity, which is why installing solar panels significantly reduce air pollution.

Photochemical smog, often referred to as "summer smog", is the chemical reaction of sunlight, nitrogen oxides and volatile organic compounds in the atmosphere, which leaves airborne particles and ground-level ozone.

Both exhaust gas recirculation (EGR) and selective catalytic reduction (SCR) technologies can be used to reduce nitric oxide (NOx) emissions, while the PM emission control requires a diesel particulate filter (DPF).

This would effectively reduce the emissions of smog-causing chemicals, and result in clearer, healthier air around urban centers. ... Acid rain is formed when sulfur dioxide and nitrogen oxides react with water vapor and other chemicals in the presence of sunlight to form various acidic compounds in the air.

This reduces the amount of coal that must be burned, which reduces emissions of greenhouse gases. In a single year, the use of CFLs over incandescent bulbs removes as much greenhouse gas pollution as taking 2 million cars off the road [source: ENERGY STAR].

The major undesirable components of photochemical smog are nitrogen dioxide (NO2), ozone (O3), PAN (peroxyacetylnitrate), and chemical compounds that contain the –CHO group (aldehydes). PAN and aldehydes can cause eye irritation and plant damage if their concentrations are sufficiently high.
