It irritates your eyes, throat, and lungs. It can also harm plants and other living things. Photochemical smog is formed by the action of sunlight on pollutants such as hydrocarbons and nitrogen oxides. these chemicals react to form a brownish mixture of ozone and other pollutants.
Auxins cause plants to respond positively to sunlight. These are chemicals found in plants that are far from a light source, which cause the plant to bend towards the sun.
Yes, indirect sunlight does cause heat, although not as much as direct sunlight does.

Yes, chemicals can cause permanent ear ringing (tinnitus). The chemicals which are best studied include aminoglycosides (a type of antibiotic, such as gentamycin). Not only do these chemicals cause tinnitus, but also deafness. There are many other medications which can cause tinnitus, which is often dose related. In addition there are countless chemicals which can cause tinnitus upon exposure. Most of these chemicals come with an MSDS sheet to explain the risks of exposure.
Yes, airborne chemicals can cause emphysema. See related link below.
Plants are made from chemicals and they release chemicals.
Only direct sunlight, which could cause them sunburn.

The ultra-violet (UV) rays in sunlight are very energetic and can affect many chemicals. Exposure to UV for long time (such as being left out in the sun) can cause the chemicals in dyes and pigments to break down and lose their colour leaving them bleached.
