“…The NAA laboratory is accredited under ISO/IEC 17025: 2005 by the Argentine Accreditation Agency (OAA) since 2001 (Resnizky et al 2006) and it is inter-calibrate with the ones located in other countries (Munita et al 2001). MR-CCHEN-003 standard reference material (trace elements in mussel muscle, Chilean Nuclear Energy Commission, Santiago de Chile, Chile) was analyzed to support the QA/ QC of As, Se, and metals measurements in tissues.…”

The anadromous catfish Genidens barbus is a vulnerable and economically important species from the Southwestern Atlantic Ocean. Concentrations of As, Co, Fe, Se, and Zn were determined in water and muscle, gill, and liver of catfish from two southwestern Atlantic estuaries (Brazil and Argentina) and health risk via fish consumption was evaluated. High spatial variability was observed in the metals, As, and Se distribution for both estuaries. Considering all tissues, element concentrations (mg/kg, wet weight) were As = 0.41-23.50, Co = 0.01-2.9, Fe = 2.08-773, Se = 0.15-10.7, and Zn = 3.97-2808). Most of the trace elements tended to be higher in Brazil than in Argentina, except for Co, Fe, Se, and Zn in liver and Fe and Co in muscle and gill, respectively. Arsenic accumulation order was muscle > liver ≥ gill. Only As (muscle) was above the maximum recommended by international guidelines at both estuaries. The target hazard quotient ranged from 0.10 to 1.58, suggesting that people may experience significant health risks through catfish consumption. Supposing that the inorganic/toxic As ranged between 1 and 20% of the total, the recommended maximum intakes per capita bases were 6.1-95 and 8.4-138 kg/year (wet weight) for Brazil and Argentina, respectively. Carcinogenic risk for As intake was within the acceptable range but close to the recommended limit (> 10 −4 ). These results highlights the importance of quantifying the As species in catfish muscle in order to generate more reliable risk estimates.

“…Only a few articles describing ABNT NBR ISO/IEC 17025 accreditation processes in radiation measurement labs were found in the literature [12][13][14][15][16][17]. As stated by Vajda et al [12], the sophisticated nature of radioanalytical work presumes a research-oriented activity, with a constant method development dynamics for special sample analysis.…”

ISO/IEC 17025 accreditation of radiation measurement test methods in the Brazilian National Commission for Nuclear Energy – Laboratory of Poços de Caldas

This paper describes the implementation process of a Quality Management System (QMS) at the Laboratory of Poços de Caldas (LAPOC) in Brazil, aiming for ISO/IEC 17025 accreditation. Due to the governmental nature of the entity, all accreditation efforts had to be undertaken on a particular legal framework – not usually favorable to QMS requirements. As the scope consisted of both chemical and radiation test methods (for which only a few labs are accredited worldwide), this initiative turned into a complex endeavor for the organization. In this sense, critical aspects on the development of a QMS are emphasized. LAPOC’s approach to achieve accreditation focused on the branches of documentation development and method validation/uncertainty estimation, whose challenges are here discussed. Upon the successful conclusion of its quality assurance project, LAPOC became the national pioneer in the field of accredited radiation measurements. This case study may be inspiring to other public institutions that struggle to obtain accreditation of radioanalytical test methods in an environment of low resources availability and restricted manpower.

“…The current demand for reliable test results reflects on the implementation of Quality Management Systems (QMS) according to ISO/IEC 17025 requirements in testing and calibration laboratories (Chung et al, 2006;Resnizky et al, 2006;Zapata-García et al, 2007;Lopes et al, 2014). Thus, seeking laboratory accreditation is, nowadays, a "survival requirement" (Cortez, 1999).…”

The evaluation of material fracture mechanic properties has had an increasing need, especially in the oil and gas industries. This scenario requires quality assurance of fracture toughness tests. This article describes the activities carried out when implementing the Quality Management System (QMS) for the fracture toughness tests at the Physical Metallurgy Laboratory (LAMEF) in the Federal University of Rio Grande do Sul (UFRGS), Brazil, in order to achieve the management and technical requirements of ISO/IEC 17025. Since LAMEF was previously accredited in performing other tests, most of the adequacy was related to the technical requirements of the ISO/IEC 17025 standard. After performing the required adjustments and after an external audit, the Brazilian Institute of Metrology, Quality and Technology (Inmetro) accredited LAMEF to the fracture toughness tests. The accreditation of these tests is unprecedented in Brazil, and we expect this work to encourage other Brazilian and world laboratories to seek the implementation and accreditation of QMS for fracture mechanics tests.
