Toxic preservatives on old weapons?

[stekemest]

Hello forum! After being inactive for a very long time, I've been getting back into ethnographic objects a bit more in recent months. This recently led me to wonder to what extent old weapons—especially wooden ones, such as clubs or axes from Australia or Papua—were actually treated with preservatives that could still be toxic today, and to what extent this poses a danger to collectors? I haven't found a topic on this, so please excuse me if this has already been discussed. Thanks in advance for any information, and best regards from Germany! Peter
