Child in a mercury polluted pond of water

I do hate when I see this, but whatever I would do, either advice parents or tell to the license holder to refrain of allowing children to the mining site, these parents or mother with the child would just change the location to the other mercury polluted pond.

What one can see here is that mother is bringing ores for processing on this place, they are crushing ores and then recovering gold by using mercury. Too many people pour mercury in this pond shown on this picture.

Their children often help the parents and wash mercury and are in constant contact with the dangerous and poisonous substance.
