I am seeing un-usually high levels of phosphates in some IC testing that I am conducting and am suspecting the fire-retardant used in the PCB manufacture. 

	> Can someone direct me to a list of phosphorus based fire retardants that could be currently used in laminate construction?

	> Has anyone of you seen this same issue and successfully correlated it back to the PCB fire retardant?

Thanks in advance
