ARSENIC , URINE

Reference values Modification

Test code: 842

Effective update from 30/12/2020




PREVIOUS

NEW
        
      Not exposed : Less than 10 µg/g creatinine
      B.E.I. : Less than 50 µg/g creatinine
      DL(Detection limit) : 1 µg/g creatinine
      QL(Quantification limit): 3 µg/g creatinine
      1- Total arsenic concentration in urine is not the adequate indicator to assess the arsenic occupational exposure index.
      2- The concentration of "total" arsenic in urine can be strongly conditioned by the type of diet. The possible presence of arsenic in foods of marine origin, especially in bivalves (clams, oysters, mussels), in crustaceans (crabs, lobsters), in certain cold-water fish that feed on the seabed and in marine algae, must be taken into account in the interpretation of the result. The organic forms of arsenic found in foods of marine origin (mainly arsenobetaina and arsenocolina) are generally considered non-toxic and are excreted in the urine 48 hours after being ingested.
      3- The measurement of inorganic arsenic in urine at the end of the working day is recommended to assess the occupational exposure index.
