I am trying to aquire recent research, that either confirms or disproves, that salt used to generate chlorine for swimming pools is more toxic to humans than standard clorine.
I do not really understand what you mean. I reword it, tell me please if I have correctly understood:
The disinfecting products generated from salt (with an on site electrolysis) would be more toxic than the disinfection products generated by injecting chlorine in swimming pools water.
A very wide range of byproducts (haloforms, chloramines, aldehydes, phenols, etc.) is generated by the reaction of chlorine compounds with nitrogen, carbon, etc. coming from various wastes present inside the swimming pool waters. I do not think they are likely to be very different if the chorine resource comes from electrolysis or from another source: maybe chorine dioxide (which is not very likely to remain in that state for a long time anyway). Some examples of the products generated and their consequences on health can be seen in these documents:

And some other examples in other industries where chlorine is used:
