Здравствуйте!
Ни кто не спорит, что место отбора образца, часто, является важным фактором в последующем анализе отравлений. Но попробуй, заставь танатолога отбирать кровь из желудочков сердца или из бедренной вены. Проще из брюшины черпнуть.
Ещё одни занятные тезисы, но с 1985 года как-то странно, что не опубликованы аналитические данные описанных результатов.

[email protected]We studied how carbon monoxide (CO) is distributed within the human body through quantitation of CO concentrations in postmortem tissue samples from fatalities including possible CO exposure. Stored, frozen tissues were diced, sonicated in water, and 0.01-8.0 mg wet weight (ww) tissues were incubated with sulfosalicylic acid in CO-purged, septum-sealed vials. CO released into the headspace was quantitated by reduction gas chromatography. Mean tissue CO concentrations (pmol/mg ww) from subjects diagnosed to have no known CO exposure (control, N=14), died from fire (N=13), and CO asphyxiation (N=7), respectively, were: adipose (2;13;9), brain (3;13;65), muscle (15;97;297), heart (30;99;371), kidney (22;432;709, lung (54;690;2638), spleen (73;1366;3548), and blood (162;2238;5070). Carboxyhemoglobin concentrations were 1.4%, 25.2%, and 69.1% of total hemoglobin, respectively. We conclude that measurements of CO concentration in a variety of tissues can be used as markers for the degree of exogenous CO exposure and the identification of possible causes of death.

A total of 230 cases of deaths in burning spaces dating from the years 1995-2003 were investigated in Forensic Medicine Department, Silesian University of Medicine, Katowice. HbCO and HCN found in 177 blood samples ranged from 4-95 % (mean, 31,5 %) and 0,5-40,3 microg/ml (mean, 9,98 microg/ml), respectively. Moreover, ethanol was found in 122 blood samples. Its concentration ranged from 0,89-5,0 per thousand (mean, 1,45 per thousand). A comparative analysis of HbCO and HCN levels in the groups with and without ethanol showed that the range and the mean concentration of both these xenobiotics were higher in the group with no alcohol. It was also shown that the increased ethanol caused a drop in HbCO and HCN levels. To evaluate HbCO and HCN levels, the regression and correlation analysis was used.

Комментарий: из 230 случаев гибели на пожаре HbCO и цианистый водород обнаружены в 177 образцах крови в интервале 4-95% (среднее 31,5%) и 0,5-40,3 мг/л (среднее 9,98 мг/л). В 122 образцах обнаружен этанол в концентрациях 0,89-5,0 промилле (среднее 1,45 промилле). В группе с этанолом концентрации HbCO и цианистого водорода ниже, чем в группе без него.
Это я к тому, что на пожарах случаются и другие токсиканты, не только СО.
