What are the risks of using pressure-treated pine for outdoor seating?

Pressure-treated pine is a popular choice for outdoor seating due to its affordability and resistance to rot and insects. However, there are several risks associated with using this material. One major concern is the chemicals used in the treatment process, such as copper, chromium, and arsenic, which can be harmful if ingested or inhaled. Prolonged exposure to these chemicals, especially in children or pets, may pose health risks. Additionally, pressure-treated pine can warp or crack over time when exposed to extreme weather conditions, reducing its durability. To minimize risks, consider sealing the wood and using protective covers. Always weigh the benefits against the potential hazards before choosing pressure-treated pine for outdoor furniture.
