TY - JOUR T1 - A General Approach to Accreditation of Environmental Laboratories in Turkey AU - Akan, Perihan AU - Testik, Ozlem Muge PY - 2018 DA - June Y2 - 2018 DO - 10.19072/ijet.410094 JF - International Journal of Engineering Technologies IJET JO - IJET PB - İstanbul Gelisim University WT - DergiPark SN - 2149-0104 SP - 103 EP - 107 VL - 4 IS - 2 LA - en AB - In this study, the accreditation of environmental parameters and types of laboratoriesaccredited by ISO 17025 Standard were compared. In Turkey, environmentallaboratories were classified as public, private and university laboratories.Furthermore, environmental parameters considered in this study are waterquality parameters and air quality parameters. In current study, 43 waterquality parameters in university and 47 water quality parameters in public andprivate institutions were examined with regard to accredited laboratories inTurkey. Accredited water quality parameters in public and private institutionas different from universities are Total Solid, Ammonia/Ammonia Nitrogen, TotalNitrogen, and Total Kjeldahl Nitrogen. As for air quality parameters, thenumber of air quality parameters accredited in public and private institutionsis approximately twice as air parameters accredited in universities (42 and 26,respectively). The most accredited water parameter is pH, with total of 65,where 44 of them are private, 11 are public and 10 are university laboratories.Chemical Oxygen Demand (COD) and Suspended Solid (SS) are placed in the secondorder with total of 56. Here, 39 private, 10 public and 7 universitylaboratories are accredited in terms of COD and 40 private, 10 public and 6university laboratories are accredited in terms of SS. Conductivity is nextremarkable parameter with total of 53 institutions (37 private, 8 public and 8university laboratories). In air parameters, the most accredited one is the SO2,with total of 52 (49 private, 2 public and 1 university laboratory).
