Regarding the analysis performed in TDS, international guidelines published by the World Health Organization, recommend selecting and confirming the validity of suitable analytical methods to achieve the purpose of TDS. However, concrete procedures and/or approaches for confirming the validity of suitable methods have yet to be established. In the present study, we aimed to develop samples, referred to as SEMPs; Samples to estimate methods performance, that can be used to evaluate the performance of the analytical methods applied to the composite samples prepared in TDS. The concentrations of 14 kinds of elements, including hazardous substances such as arsenic, lead, and cadmium, in SEMPs were measured for use in the validation of a multi-element analytical method for estimating dietary intake. After examining the appropriate amount of relevant elements added to the samples, we established a performance evaluation procedure by repeatedly analyzing five fortified and non-fortified SEMPs each.As a method to detect pesticide residues in agricultural products, we evaluated the pretreatment of agricultural product samples by the solid-phase extracton technique with QuEChERS (STQ) method followed by GC-MS/MS with large-volume injection using a stomach-type glass-lined injector. This method satisfied the target criteria of recovery (70-120%) and the standard deviation of repeatability (RSD less then 25%) in 238-282 pesticides found in six types of agricultural products.DNA from hair that has undergone retort pouch sterilization shows considerably more fragmentation. Assessing the extent of DNA fragmentation using a PCR assay could therefore be applied to infer the sterilization history of
