卡特里娜飓风带来的灾难残骸是美国历史上规模最大、经济损失最大的飓风之一。拆迁碎片的主要成分之一是木材废料，其中很大一部分是用防腐剂处理的，包括含砷的防腐剂。由于电线杆、栅栏、甲板和房屋等处理过的木结构被大规模破坏，相当数量的处理过的木材和砷将作为灾难碎片处理。在这项研究中，努力估计了卡特里娜飓风在路易斯安那州和密西西比州地区产生的拆迁碎片所处理的砷的数量。在产生的7200万立方米灾害碎片中，大约1200万立方米是建筑和拆迁木材，估计处置了1740吨砷。灾害残骸的管理应考虑到与压力处理木材有关的相对大量的砷。
The disaster debris from Hurricane Katrina is one of the largest in terms of volume and economic loss in American history. One of the major components of the demolition debris is wood waste of which a significant proportion is treated with preservatives, including preservatives containing arsenic. As a result of the large scale destruction of treated wood structures such as electrical poles, fences, decks, and homes a considerable amount of treated wood and consequently arsenic will be disposed as disaster debris. In this study an effort was made to estimate the quantity of arsenic disposed through demolition debris generated in the Louisiana and Mississippi area through Hurricane Katrina. Of the 72 million cubic meters of disaster debris generated, roughly 12 million cubic meters were in the form of construction and demolition wood resulting in an estimated 1740 metric tons of arsenic disposed. Management of disaster debris should consider the relatively large quantities of arsenic associated with pressure-treated wood.
