Sodium bicarb and bisulfate won't harm you. They dissociate in aqueous solution and fuck up the plants but good, but won't be uptaken in any form hazardous to humans. The skin problems from pools are most often high pH, which is VERY irritating to skin and mucous membranes, and the chloride and bromide that are used to kill bacteria.
It's moot, though- you can't grow a plant to harvest with that much sodium kicking around. lol!

Things you would want to be wary of are organic compounds- specifically, pesticides not labelled for food crops. NEVER use those ANYWHERE near your flowering plants, and be hesitant to use them in ANY life stage.
