Conventionally, as a method for preventing such damage by pests in water, control using chemicals such as inorganic heavy metal compounds, organic metal compounds, heavy metal salts, and inorganic and organic halogen agents has been performed. For example, antifouling paint is conventionally applied to the bottom surface of a ship, the surface of a seawater introduction channel, a fishing net, and the like, and the antifouling paint is made of an inorganic copper compound or an organic tin compound as an antifouling agent. Are mainly used.
In the cooling water system, chemicals such as organic metal agents, inorganic and organic halogen agents, and peroxides are dissolved or dispersed directly or in combination with a wettable powder and added to the water system. Control with these agents often does not show sufficient effects at low concentrations of dissolution and dissolution, and furthermore, at effective concentrations, it is simultaneously toxic and highly persistent, which is not preferable from the viewpoint of environmental health and pollution.
