There is also some evidence to suggest that exposure to titanium dioxide nanoparticles may be harmful or toxic to the environment, including aquatic life and other organisms. The production and disposal of the mineral may also release pollutants, such as carbon dioxide and sulfur dioxide, into the air and water.

This is all due to the fact that aluminium does not have as much ability to absorb heat. However, we should add that in reality its temperature will often be the same as that of the aforementioned wood.
