A few pictures here for the library on sodium chloride damage on raspberry. Leave tissue concentration of sodium is over 250 ppm and chloride over 20,000 ppm (that's 2% of total dry tissue!). Interestingly accumulation of the micronutrients zinc and copper in these plants is also notably higher than what would be normal for raspberry.
