For example, if we compare the US EPA's suggested that PFOA and PFOS is recommended not to exceed 400 ng/L and 200 ng/L.In drinking water, it can be seen that in water and drinking water has not yet exceeded PFOS and PFOA, it.Or considering the introduction of new jersey charges state that suggests that PFOA concentration less than 40 ng/L, from measuring the concentration of PFOA in water and drinking water, it is not beyond them as well.
