Industrial Applications

Arsenic plays a significant role in various industrial processes. It is primarily used in the manufacturing of pesticides, herbicides, and insecticides due to its effectiveness in controlling pests and unwanted vegetation. These compounds are crucial for agricultural productivity but require careful handling due to their toxicity.

• Pesticides and Herbicides: Arsenic compounds have been historically used to protect crops from pests and weeds. Despite the decline in their usage due to health concerns, some arsenic-based chemicals are still employed, particularly in industrial agriculture.
• Wood Preservation: Arsenic trioxide has been used in wood preservatives to protect against rot and insect damage. While less common today, it was widely used in the past.
