Method 1613 of US Environmental Protection Agency (US EPA) was used for the PCDD detection in the objects of environment (water, soil etc.). PCDD detection was done with the help of Polaris Q gas chromatograph/ mass spectrometer on mass-spectrum of electronic impact in the MS-MS mode. Division of isomer PCDD was carried out on a capillary column from the sintered quartz DB-5 MS (60 m x 0,25 mm, thickness of tape 0,25 p.m). The same device was used for detection of fungicides formulations active ingredients in soil.

Ethene and propene are produced as bulk feedstocks for the chemical (polymer) industry and therefore their purities are important parameters. In particular, H2S and COS are compounds which may not only cause corrosion problems in processing equipment, but also may have detrimental effects on the catalysts in use. Eurthermore, air pollution regulations issued by, among others, the US Environmental Protection Agency (EPA) require that most of the sulfur gases should be removed in order to minimize Sulfur emissions into the atmosphere. Therefore, these compounds have to be determined to the ppb level.

The definitions of method detection and quantification limits should be reliable and applicable to a variety of extraction procedures and analytical methods. The issue is of particular importance to the US Environmental Protection Agency (EPA) and also pesticide regulatory and health agencies around the world in risk assessment. The critical question central to risk assessment is assessing the risk posed to a human being from the consumption of foods treated with pesticides, when the amount of the residue present in the food product is reported nondetect (ND) or no detectable residues . 

Finally, to avoid the parallel use of similar but not identical method validation studies to fulfil the registration requirements, e.g., of the EU, US Environmental Protection Agency (EPA) or Japanese authorities, an adaptation of different data requirements for residue analytical methods for post-registration control and monitoring purposes would help to save resources.
