Concentrated phosphoric acid risks
WebIn adults, normal phosphate concentration in serum or plasma is 2.5 to 4.5 mg/dL (0.81 to 1.45 mmol/L) . Hypophosphatemia is defined as serum phosphate concentrations lower than the low end of the normal range, whereas a concentration higher than the high end of the range indicates hyperphosphatemia. WebConcentrated phosphoric acid ingestion produces local caustic effects on the mucosa of the oropharynx, oesophagus and stomach analogous to other strong acids (Hawkins et al, 1980; Caravati, 1987).
