Sample: Urine in post-shift at end of workweek Results format: R1 µg/L R2 µg/g creatinine Reference Values: V.L.B. : 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. * Source: Enciclopedia de salud y seguridad en el trabajo, tomo I, 27 - INSHT ATSDR(Agency for Toxic Substances and Disease Registry), 2007 * Fuente: Valores Bibliograficos Version of Test: 25 | Sample: Urine Results format: R1 µg/L Reference Values: Less than 100 µg/L 1- The concentration of "total" arsenic in urine is not an appropriate indicator for assessing the occupational exposure index to arsenic. 2- The concentration of "total" arsenic in urine can be strongly influenced by diet. The possible presence of arsenic in marine-origin foods—especially in bivalves (clams, oysters, mussels), crustaceans (crabs, lobsters), certain cold-water fish that feed on the seabed, and seaweed—should be considered when interpreting the results. The organic forms of arsenic found in marine-origin foods (mainly arsenobetaine and arsenocholine, also known as "fish arsenic") are generally considered non-toxic and are excreted in urine within 48 hours of ingestion (ATSDR, 2007). 3- It is recommended to measure inorganic arsenic in end-of-workday urine to assess the occupational exposure index. * Source: ATSDR(Agency for Toxic Substances and Disease Registry), 2007 Version of Test: 26 |
