15、s, gasoline components (such as BTEX, MTBE, and ETBE), naphthalene, 2-ethyl-4-methyl-1,3-dioxolane, and highly odorous substances like geosmin and 2-methylisoborneol; c) the principle of the method has not been changed, but it now includes the option to extend the extraction time of medium volatile

16、substances since this can lead to an increase in the detection sensitivity of these substances, e.g. geosmin; d) the method is now also applicable to the matrix “treated waste water”; e) Clause 4 “Interferences” has been rendered more precise; reference to International Standards on sampling has bee

45、uctionVolatile organic compounds (VOCs) are often found in the manufacturing processes of paints, adhesives, petroleum products, pharmaceuticals, and refrigerants. Some are used as gasoline additives, solvents, hydraulic fluids, and dry-cleaning agents. This group of compounds belongs to the group o

46、f anthropogenic chemicals. VOC contamination of water resources is a human-health concern because many are toxic and are known or suspected human carcinogens.For the determination of VOCs, several published procedures are available (see References 4,5,6,7,9,12,13, and 14).EN ISO 17943:2016 (E) DIN E
