NEW! SECOND ROUND OF MICROPLASTICS INTERLAB STUDY IS UNDERWAY
Scroll down for details on timeline of upcoming activities, workshops, downloads and information on upcoming interlaboratory rounds.
Microplastics are emerging environmental contaminants that pose growing concerns for the environment and potentially also human health. There is an urgent need to measure plastic particles of all sizes (nano to micro) for research purposes, and to provide high quality data on spatial and temporal trends of plastic particles in a wide range of sample matrices. However the environmental contaminant analysis community is challenged to provide such data. For example, the current lack of sufficient quality assurance and quality control (QAQC) tools such as interlaboratory studies and reference materials hinders comparable results between laboratories. The Dept. of Environment and Health of the Vrije Universiteit has recognized the need for an open interlaboratory study on plastic particles in a variety of sample matrices and teamed up with interlaboratory study provider QUASIMEME, NIVA and the NORMAN network to meet this need.
What are Microplastics?
MICROPLASTICS INTERLABORATORY STUDY SECOND ROUND (2020-2021)
Academic, research, government and commercial analytical laboratories worldwide wishing to demonstrate their microplastic analysis proficiency and join an international network of laboratories with common goals. Laboratories measuring plastic particles in both the nano and micro size ranges using a range of sample preparation and analytical techniques are accommodated in this initiative.
Participation in interlaboratory studies is an important way that analytical laboratories can help assure the quality of their measurements. The approach taken here is to organize workshops to discuss study results among participants and learn how to improve performance throughout a series of analysis rounds of increasing complexity. Participation helps laboratories detect potential biases in their analytical results, uncertainties and sources of error.
Interlaboratory studies help labs demonstrate their proficiency and competence. For labs interested in (future) accreditation, proficiency testing is required. Participation in interlaboratory studies increase confidence in the data produced, both for the data producers and the data users. The consequences of errors in test results may be costly, especially compared to the low cost of participation in an interlaboratory study. Each participating laboratory is confidentially informed of their own results and receives a study report presenting the overall results among all the anonymized participating laboratories. Participants benefit from follow-up workshops in which the study results of the testing rounds are discussed in light of analytical performance of different methods used.
