The correct choice, which indicates a method that is not a pitting control strategy, is the introduction of toxic substances. This strategy does not relate to preventing or mitigating pitting corrosion; instead, it could potentially exacerbate the problem or create additional environmental and health risks.

Pitting corrosion is a localized form of corrosion that leads to the creation of small pits or holes in a material, often metals. Effective pitting control strategies typically focus on alterations to the material itself, such as selecting corrosion-resistant alloys, or modifying the environment, like controlling pH levels or reducing acidic conditions that can lead to pitting. Protective coatings serve as a barrier between the metal and the corrosive environment, effectively reducing the chances of pitting.

In contrast, the introduction of toxic substances does not contribute to these strategies, making it the less viable option when considering methods to control pitting corrosion.
