This European Standard specifies the extraction processes and gas chromatographic (GC) methods for determining parathion, parathion-methyl and some other organophosphorus compounds in drinking waters, surface waters and waste waters. This standard may also be suitable for the determination of other organic compounds. The range is dependent on the compound and the source of water and is typically up to 1 ug/l with a reporting limit of 0,001 ug/l for drinking waters involving a 1 000 to 1 extraction ratio.
