ABSTRACT
OBJECTIVE:
To analyze the results of inter-laboratory comparison among occupational hygiene laboratories.METHODS:
A convenient sampling method was used. The laboratories participating in the inter-laboratory comparison organized by the Guangdong Occupational Health Test Center from 2013 to 2017 were selected as study subjects. The data of detection of organic compounds, metal element, inorganic non-metal element in workplace air, detection of metal element in biological materials, and detection of free silica in dust were analyzed. The results were statistically analyzed by four-point robust statistical technique.RESULTS:
A total of 615 laboratories(times) participated in the comparison, and 2 785 items of sample detection results were submitted from 2013 to 2017.Among them, a total of 2 484 items were tested qualified and the sample test qualified rate was 89.2%. The test qualified rates of organics in workplace air, metals in workplace air, inorganic nonmetals in workplace air, metals in biological materials and free silica in dust were 91.1%, 92.0%, 86.6%, 80.4% and 85.0%, respectively. The sample test qualified rates of the laboratories in different regions from high to low were the laboratories Pearl River Delta region in Guangdong Province, the laboratories in non-pearl river delta region in Guangdong Province and the laboratories outside of Guangdong Province were 91.6%, 87.2% and 72.6%(P<0.01), respectively. The sample test qualified rate of the public laboratories was higher than that of the private laboratories(90.3% vs 87.0%, P<0.05).CONCLUSION:
The accuracy of the occupational hazard factor test in the participating laboratories needs to be improved. It is necessary to further strengthen the investment, supervision and management to non-pearl river delta region laboratories and private laboratories in Guangdong Province.
