I got a package today with the "dead tree & fish" label on it & a
13-page safety data sheet inside. It turns out that desoldering braid
is so labelled because copper is "aquatic acute 1, H400" and "aquatic
chronic 1, H410". (The other component, rosin, is marked as "skin
sens. 1, H317".)

I'm a bit surprised that copper is apparently safe to contain & carry
drinking water but a hazard if dropped in water outside. What am I
missing here?


Wooden ships used to be sheathed in copper in order to prevent marine
life from growing on the hull. SFAIK it is still used in antifouling paints.
