Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials
material Abstract: An approach for the size measurement of particulate (nano)materials by transmission electron microscopy was evaluated. The approach combines standard operating procedures for specimen ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography- tandem mass spectrometry
negative electrospray ionization. Labeled internal standards and matrix-matched calibration are used for quantification of the compounds. The method was validated according FDA guideline for bio analytical ...

Revealing the identification power of CCS: A novel approach applied to pesticide analysis in food
a Synapt G2-S using a series of standard solutions, spiked matrices and a previous proficiency test. CCS values were generated from the standard solutions and inserted into a scientific library within a new ...
Scientific Opinion of the EFSA Panel on Plant Protection Products and their Residues (PPR), Guidance on the use of probabilistic methodology for modelling dietary exposure to pesticide residues
performing probabilistic dietary exposureassessment of single or multiple active substances, as a potential additional tool to supplement orcomplement the standard deterministic methodologies which are ...
Cytome assay in two cell lines exposed to ELF-magnetic fields: An investigation on the relation between exposure to ELF-magnetic fields and an alleged increased risk for Alzheimer's disease.
in terms of Alzheimer's disease. Cells were cultivated in the laboratory according to standard methods and exposed to 10, 50 100 and 500 µT ELF- MF 's according to different exposure ...
Quality of laboratory studies assessing effects of Bt-proteins on non-target organisms: minimal criteria for acceptability
studies meeting certain quality standards as this minimises the probability of erroneous or inconclusive results and increases confidence in the results and adds certainty to the conclusions drawn. Health ...
A novel approach to model 4 decades of marine chemical data
grain size, etc. is reduced thanks to standardized OSPAR guidelines. This facilitates comparability of data within and between regions and assessments based on 5-15 year timetrends are frequently made. ...
