I was watching a documentary last night, about exposure to Neuro-toxins.
It was on DW (German) TV.
A few people from Germany had suffered nasty effects of un-packing goods sent from among the suppliers, India and larger Asia.
Mainly what this had caused was severe head-aches and damage to the Central-Nervous system of those concerned, culminating in severe shaking, not unlike the most advanced stages of Parkinsons or Alzhiemers Disease.
However the documentary went on to show crop farmers of Cotton, using nasty chemicals with no protection, that we would not got out on a field like that without.
One instance, a worker using a "power-sprayer" to spray a crop of cotton with DDT, to rid the crop of pests, with not one bit of PPE on.
One guys Spray pack had run out, so another guy, refills his pack, with DDT diluted with water, the pack is over-filled, so it runs all over him.
The same thing is prevalent in the factories, a lot of workers complaining of constant itchy-ness with the dying processes, the waste dye/water just runs into the drains and is drank by the general public, through their water supply.
I don't want to start a political argument about the poorer countries here, but, you could be wearing some of that clothing.
It's only washed so well in it's country of origin.
Could some of the staff in the Warehouses near where you are be exposed to the same sort of thing?.
