Provided is a titanium oxide composition that has a high capability to decompose odor-causing substances, is less likely to cause re-emission of an odor-causing substance(s) due to adsorption of water, and exhibits an excellent particle dispersion stability. The titanium oxide composition contains titanium oxide particles, a component A and a component B. The component A is at least one kind selected from a group of sepiolite and attapulgite, and the component B is at least one kind selected from a group of high silica zeolite and hydrophobic silica. A mass ratio of the component A to the titanium oxide particles is 0.75 to 3.25, and a mass ratio of the component B to the component A is 0.25 to 3.0. Also provided is a member having such titanium oxide composition on its surface.

A method of controlling odor where the odor is generated by sources like decomposing organic matter in landfills or other sources is provided. A wood vinegar-containing solution, adjusted for the source of the odor, can be applied to the source of the odor. A method of improving the rate and completeness of settling of fine clays from oil sands tailings is also provided. Additional disclosure of a method of controlling algae bloom in a body of water is disclosed. The method includes the steps of providing a wood vinegar-containing solution, adjusting the composition of the wood vinegar-containing solution according to the states of both the body of water and the algae, respectively, then applying the wood vinegar-containing solution to the surface of a body of water, and inhibiting growth of the algae responsible for the algae bloom.
