Should existing structures build from CCA-treated wood be removed? Which argument did you find most convincing?
CCA treatment has been in use for about 80 years, with no recorded incidents of arsenic poisoning to the general public. (The small number of people who've suffered health problems due to CCA have mainly been construction workers). Occasional contact with CCA-treated wood will only lead to very small levels of arsenic (if any) entering the human body and, as the experiences of Victorian times show (when arsenic was widely taken for its supposed health-giving properties), people can build up a tolerance to it.
Further, the practical difficulties of working out which picnic tables and decking (for example) in people's gardens are made out of CCA-treated wood, and then disposing of it all, far outweigh any theoretical benefits from doing so.
So in short, it can be dangerous but there is no evidence showing that the already built structures can be harmful.

CCA (Chromated Copper Arsenate) is a wood preservative used to protect against decay and insect damage. It contains arsenic, a toxic substance. The decision to remove existing structures built from CCA-treated wood depends on a variety of factors, including the level of risk, local regulations, and personal preference.
There are arguments both for and against removing structures built from CCA-treated wood:
1. Health and Environmental Concerns: The main argument for removal is the potential health risks associated with CCA-treated wood. Over time, the chemicals can leach from the wood and contaminate the surrounding soil, groundwater, and potentially expose people and animals to harmful levels of arsenic. Removing such structures can mitigate these risks.
2. Cost and Practicality: On the other hand, removing existing structures can be expensive and time-consuming. It may involve demolishing and disposing of the wood in an environmentally responsible manner, as well as potentially replacing the structure with alternative materials. The cost and effort involved may make removal less feasible for some individuals or communities.
Deciding which argument is most convincing is subjective and depends on individual circumstances. If you're concerned about potential health risks or are following specific regulations, then the health and environmental argument may be more convincing. However, if removal is not economically or practically feasible, the cost and practicality argument might hold more weight.
It is advisable to consult with experts, such as environmental agencies, local authorities, or professionals in the field, to get specific advice based on your situation and location.
