This standard is intended to identify and measure mass concentrations of 17 highly toxic polychlorinated dibenzo-n-dioxins and dibenzofurans: 2,3,7,8-tetrachlorodibenzo-n-dioxin, 2,3,7,8-pentachlorobibenzo-n-dioxin; 1,2,3,4,7,8-hexachlorodibenzo-p-dioxin; 1,2,3,6,7,8-hexachlorodibenzo-p-dioxin; 1,2,3,7,8,9-hexachlorodibenzo-p-dioxin; 1,2,3,4,6,7,8-heptachlorodibenzo-p-dioxin; octachlorodibenzo-p-dioxin; 2,3,7,8-tetrachlorodibenzofuran; 1,2,3,7,8-pentachlorodibenzofuran; 2,3,4,7,8-penta-chlorodibenzofuran; 1,2,3,4,7,8-hexachlorodibenzofuran; 1,2,3,6,7,8-hexachlorobibenzofuran; 2,3,4,6,7,8-hexachlorodibenzofuran; 1,2,3,7,8,9-hexachlorobibenzofuran; 1,2,3,4,6,7,8-heptachlorodibenzofuran; 1,2,3,4,7,8,9-heptachloro-benzofuran; octachlorodibenzofuran, as well as 14 dioxin-like planar polychlorinated biphenyls (PCB): 3,3 ', 4,4'-tetrachlorobiphenyl; 3,4,4 ', 5-tetrachlorobiphenyl; 2,3,3 ', 4,4'-pentachlorobiphenyl; 2,3,4,4 ', 5-pentachlorobiphenyl; 2,3 ', 4,4', 5-pentachlorobiphenyl; 2 ', 3,4,4', 5-pentachlorobiphenyl; 3.3 ', 4.4', 5-penta-chlorobiphenyl; 2,3,3 ', 4,4', 5-hexachlorobiphenyl; 2,3,3 ', 4,4', 5'-hexachlorobiphenyl; 2,3 ', 4,4', 5,5'-hexachlorobiphenyl; 3,3 ', 4,4', 5,5'-hexachlorobiphenyl; 2.2 ', 3.3', 4.4 ', 5-heptachlorobiphenyl; 2,2 ', 3,4,4', 5,5'-heptachlorobiphenyl; 2,3,3 ', 4,4', 5,5'-heptachlor-biphenyl in fish, marine invertebrates and products of their processing. The analysis method is based on the extraction of analytes with organic solvents, sequential purification of the extract using gel filtration and column chromatography on various sorbents and quantitative chromatography-mass spectrometry using surrogate isotope-labeled standards - analogs of the detected compounds introduced into the sample at the sample preparation stage . The detection limit of various congeners is respectively from 0.1 to 0.5 ng

Настоящий стандарт предназначен для идентификации и выполнения измерений массовых концентраций 17 высокотоксичных полихлорированных дибензо-n-диоксинов и дибензофуранов: 2,3,7,8-тетрахлордибензо-n-диоксина, 2,3,7,8-пентахлордибензо-n-диоксина; 1,2,3,4,7,8-гексахлорди-бензо-n-диоксина; 1,2,3,6,7,8-гексахлордибензо-n-диоксина; 1,2,3,7,8,9-гексахлордибензо-n-диоксина; 1,2,3,4,6,7,8-гептахлордибензо-n-диоксина; октахлордибензо-n-диоксина; 2,3,7,8-тетрахлордибензофурана; 1,2,3,7,8-пентахлордибензофурана; 2,3,4,7,8-пента-хлордибензофурана; 1,2,3,4,7,8-гексахлордибензофурана; 1,2,3,6,7,8-гексахлор-дибензофурана; 2,3,4,6,7,8-гексахлордибензофурана; 1,2,3,7,8,9-гексахлор-дибензофурана; 1,2,3,4,6,7,8-гептахлордибензофурана; 1,2,3,4,7,8,9-гептахлорди-бензофурана; октахлордибензофурана, а также 14 диоксиноподобных планарных полихлорированных бифенилов (ПХБ): 3,3',4,4'-тетрахлорбифенила; 3,4,4',5-тетрахлорбифенила; 2,3,3',4,4'-пентахлорбифенила; 2,3,4,4',5-пентахлорбифенила; 2,3',4,4',5-пентахлорбифенила; 2',3,4,4',5-пентахлорбифенила; 3,3',4,4',5-пента-хлорбифенила; 2,3,3',4,4',5-гексахлорбифенила; 2,3,3',4,4',5'-гексахлорбифенила; 2,3',4,4',5,5'-гексахлорбифенила; 3,3',4,4',5,5'-гексахлорбифенила; 2,2',3,3',4,4',5-гептахлорбифенила; 2,2',3,4,4',5,5'-гептахлорбифенила; 2,3,3',4,4',5,5'-гептахлор-бифенила в рыбе, морских беспозвоночных и продуктах их переработки. Метод анализа основан на экстракции аналитов органическими растворителями, последовательной очистке экстракта с применением гель-фильтрации и колоночной хроматографии на различных сорбентах и количественном анализе методом хромато-масс-спектрометрии с использованием суррогатных изотопно-меченых стандартов - аналогов определяемых соединений, вводимых в пробу на стадии пробоподготовки. Предел обнаружения различных конгенеров составляет соответственно от 0,1 до 0,5 нг/кг. Определению не мешает присутствие в образцах пестицидов, полихлорированных бифенилов и прочих галогенированных соединений
