On cardboard and paper it lasts a matter of hours in general, ditto on fabrics
On plastics/metals around 3 days (other than copper etc).
As for morality. Tough one. A Brexity mate is extolling the virtues of buying British and to some degree he has a point. Shorter supply chains, supporting UK industry etc. but as I pointed out to him, could he spec me a British designed, manufactured and assembled TV for me to buy British?
Also asked if he would be buying British non oem parts from now on for his VW?
Back to the health side, I’m more concerned about food/packaging coming into the house from this country to be honest, as someone said above. That all gets sprayed and where possible left for 3 days before being used/stored away.
