What is one of the primary advantages of using inorganic arsenicals?

The primary advantage of using inorganic arsenicals lies in their effectiveness as a wood preservative. These compounds are particularly toxic to fungi and insects, making them highly valuable in protecting wood products from decay and damage caused by these organisms. This broad spectrum of pest control includes protection against various wood-destroying fungi, termites, and other insects, as well as resistance to marine borers in certain aquatic environments.

While some preservatives might be non-toxic, the key benefit of inorganic arsenicals is their ability to severely limit the degradation of wood from biological threats, thus extending the lifespan of treated wood products. Due to their effectiveness, these compounds have been widely used in the wood industry for applications requiring robust protection against a range of organisms.
