What indicates physical signs of chemical contamination in wood?

The presence of discoloration, odor, or soft/spongy wood serves as important indicators of physical signs of chemical contamination in wood. Discoloration can suggest that the wood has been exposed to harmful chemicals that affect its natural coloration. Similarly, an unusual odor may indicate the presence of volatile organic compounds or other substances that have penetrated the wood, reflecting contamination. Additionally, when wood becomes soft or spongy, it often signifies that chemical exposure has compromised its structural integrity, making the material less reliable and potentially dangerous for construction purposes. These signs collectively point to underlying chemical issues that require further investigation and action to ensure safety.
