早期的研究记录了新木材中木材防腐剂的损失。本研究的目的是通过收集5种不同木材类型的降雨渗滤液，评估在野外条件下风化处理木材的损失，所有木材的表面积为0.21平方米。木材样品包括经低（2.7千克/立方米）、中（4.8千克/立方米）和高（35.4千克/立方米）保留水平铬酸铜砷酸盐（CCA）处理过的风化木材、新的碱性铜季铵盐（ACQ）处理过的木材（1.1千克/立方米CuO）和新的未经处理的木材。在所有铬化砷酸铜处理过的木材样品中，砷的浸出率（低保留率1年100毫克）高于铬和铜（<40毫克）。ACQ样品中铜的浸出率最高（670毫克）。总体结果表明，金属的淋溶是一个由降雨驱动的连续过程，从木材基质中释放的机制随着木材的风化而变化。
Earlier studies documented the loss of wood preservatives from new wood. The objective of this study was to evaluate losses from weathered treated wood under field conditions by collecting rainfall leachate from 5 different wood types, all with a surface area of 0.21 m2. Wood samples included weathered chromate copper arsenate (CCA) treated wood at low (2.7 kg/m3), medium (4.8 kg/m3) and high (35.4 kg/m3) retention levels, new alkaline copper quat (ACQ) treated wood (1.1 kg/m3 as CuO) and new untreated wood. Arsenic was found to leach at a higher rate (100 mg in 1 year for low retention) than chromium and copper (<40 mg) in all CCA treated wood samples. Copper leached at the highest rate from the ACQ sample (670 mg). Overall results suggest that metals’ leaching is a continuous process driven by rainfall, and that the mechanism of release from the wood matrix changes as wood weathers.
