Authentication of vegetable oils by bulk and molecular carbon isotope analyses with emphasis on olive oil and pumpkin seed oil

The authenticity of vegetable oils consumed in Slovenia and Croatia was investigated by carbon isotope analysis of the individual fatty acids by the use of gas chromatography-combustion-isotope ratio mass spectrometry (GC/C/IRMS), and through carbon isotope analysis of the bulk oil. The fatty acids from samples of olive, pumpkin, sunflower, maize, rape, soybean, and sesame oils were separated by alkaline hydrolysis and derivatized to methyl esters for chemical characterization by capillary gas chromatography/mass spectrometry (GC/MS) prior to isotopic analysis. Enrichment in heavy carbon isotope (C-13) of th, bulk oil and of the individual fatty acids are related to (1) a thermally induced degradation during processing (deodorization, steam washing, or bleaching), (2) hydrolytic rancidity (lipolysis) and oxidative rancidity of the vegetable oils during storage, and (3) the potential blend with refined oil or other vegetable oils. The impurity or admixture of different oils may be assessed from the delta C-13(16:0) VS. delta C-13(18:1) covariations. The fatty acid compositions of Slovenian and Croatian olive oils are compared with those from the most important Mediterranean producer countries (Spain, Italy, Greece, and France).

Climatic and anthropogenic influence on the stable isotope record from bulk carbonates and ostracodes in Lake Neuchatel, Switzerland, during the last two millennia

Lake Neuchatel is a medium sized, hard-water lake, lacking varved sediments, situated in the western Swiss Lowlands at the foot of the Jura Mountains. Stable isotope data (delta(18)O and delta(13)C) from both bulk carbonate and ostracode calcite in an 81 cm long, radiocarbon-dated sediment core represent the last 1500 years of Lake Neuchatel's environmental history. Comparison between this isotopic and other palaeolimnologic data (mineralogical, geochemical, palynological, etc.) helps to differentiate between anthropogenic and natural factors most recently affecting the lake. An increase in lacustrine productivity (450-650AD ca), inferred from the positive trend in delta(13)C values of bulk carbonate, is related to medieval forest clearances and the associated nutrient budget changes. A negative trend in both the bulk carbonate and ostracode calcite delta(18)O values between approximately 1300 and 1500AD, is tentatively interpreted as due to a cooling in mean air temperature at the transition from the Medieval Warm Period to the Little Ice Age. Negative trends in bulk carbonate delta(18)O and delta(13)C values through the uppermost sediments, which have no equivalent in ostracode calcite isotopic values, are concomitant with the recent onset of eutrophication in the lake. Isotopic disequilibrium during calcite precipitation, probably due to kinetic factors in periods of high productivity is postulated as the mechanism to explain the associated negative isotopic trends, although the effect of a shift of the calcite precipitation towards the warmer months cannot be excluded.

Letter health consultation : Olin former petroleum bulk plant, Olin, Jones County, Iowa (2010)

This letter has been prepared as a consultation to evaluate human health impacts from residue contamination left from the operation of a bulk plant located in Olin, Iowa. The Iowa Department of Public Health’s priority is to ensure the Olin community has the best information possible to safeguard its health. That information is included in following paragraphs.

Health consultation : Buchanan Bulk Oil -- Ma & Pa Stores West 6th Avenue and South F Street, Oskaloosa, Mahaska County, Iowa (2006)

The Iowa Department of Natural Resources (IDNR) has requested the Iowa Department of Public Health (IDPH) Hazardous Waste Site Health Assessment Program to evaluate the potential health impacts of the future development at the Buchanan Bulk Oil – Ma & Pa Stores site. A Targeted Brownfields Assessment was completed by the IDNR at this site to measure existing on-site contaminants. Assistance was sought from the IDPH to determine potential health risks if the site was developed for residential use. This health consultation addresses potential health risks to people from exposure to the contaminants found in the soil and groundwater within the property boundary. The information in this health consultation was current at the time of writing. Data that emerges later could alter this document’s conclusions and recommendations.

Health consultation : Rolfe aboveground storage tank petroleum bulk plant targeted brownfields assessment, Railroad Street and 300th Avenue, Rolfe, Pocahontas County, Iowa (2005)

The Iowa Department of Natural Resources (IDNR) has requested the Iowa Department of Public Health (IDPH) Hazardous Waste Site Health Assessment Program evaluate future health impacts of exposures at a former aboveground storage tank site located in Rolfe, Iowa. The former aboveground storage tank site is located to the southwest of the intersection of Railroad Street and 300th Avenue in Rolfe, Iowa. This site is undergoing a Targeted Brownfields Assessment conducted by the Contaminated Sites Section of the IDNR. This health consultation addresses potential health risks to people from future exposure to the soil within the property boundary, and any health impacts resulting from contaminated groundwater beneath the site property. The information in this health consultation was current at the time of writing. Data that emerges later could alter this document’s conclusions and recommendations.

Basin-internal derivation of hydrocarbons in the Witwatersrand Basin, South Africa: evidence from bulk and molecular δ13C data

Gold in the quartz-pebble conglomerates of the late Archean Witwatersrand Basin, South Africa, is often intimately associated with carbonaceous matter of organic/biogenic origin which occurs in the form of stratiform carbon seams and paragenetically late bitumen nodules. Both carbon forms are believed to be formed by solidification of migrating hydrocarbons. This paper presents bulk and molecular chemical and stable carbon isotope data for the carbonaceous matter, all of which are used to provide a clue to the source of the hydrocarbons. These data are compared with those from intra-basinal shales and overlying dolostone of the Transvaal Supergroup. The delta C-13 values of the extracts from the Witwatersrand carbonaceous material show small differences (up to 2.4 parts per thousand) compared to the associated insoluble organic matter. This suggests that the auriferous rocks were stained by mobile hydrocarbons produced by thermal and oxidative alteration of indigenous bitumens, a contribution from hydrocarbons derived from intra-basinal Witwatersrand shales cannot be excluded. Individual aliphatic hydrocarbons of the various carbonaceous materials were subjected to compound specific isotope analysis using on-line gas chromatography/combustion/stable isotope ratio mass spectrometry (GC/C/IRMS). The limited variability of the molecular parameters and uniform delta C-13 values of individual n-alkanes (-31.1 +/- 1.7 parts per thousand) and isoprenoids (-30.7 +/- 1.1 parts per thousand) in the Witwatersrand samples exclude the mixing of oils from different sources. Carbonaceous matter in the dolostones shows distinctly different bulk and molecular isotope characteristics and thus cannot have been the source of the hydrocarbons in the Witwatersrand deposits. All the various forms of Witwatersrand carbon appear indigenous to the Witwatersrand Basin, and the differences between them are explained by variable, in general probably short (centimeter- to meter-scale) hydrocarbon migration during diagenesis and subsequent hydrothermal infiltration.

Le fait de ne pas informer un enfant quant à sa paternité biologique, dans le cas ou celle-ci est douteuse ou différente de la paternité légale, relève-t-il de la matraitance ?

La connaissance de ses origines biologiques est une question constitutive et existentielle pour chaque individu. Dans les cas d'incertitude, les expertises en paternité apportent leur contribution dans l'inclusion ou l'exclusion d'un lien de paternité/filiation biologique. La sous-commission « Filiation et droits de l'enfant » a été chargée d'apporter une réponse à plusieurs questions sur les origines biologiques dont la question suivante : "S'il est considéré comme étant de la maltraitance envers un enfant de lui cacher la véritable identité de son père biologique (marié à sa mère ou pas) ?» La sous-commission a entrepris un travail de réflexion et a départagé la question en 3 volets : juridique, psychologique et médical. Le but de notre travail est d'apporter une réponse médicale, fondée sur l'expérience pratique des médecins, à la question suivante : « Le fait de ne pas informer un enfant quant à sa paternité biologique, dans le cas ou celle-ci est douteuse ou différente de la paternité légale, relève-t-il de la maltraitance ? » Nous présentons tout d'abord une revue de la littérature concernant les sujets de la paternité, de la filiation, de la maltraitance. Nous avons consulté 935 praticiens généralistes, psychiatres et pédiatres par le biais d'un questionnaire à choix multiple de 25 questions et nous avons analysé les 263 exemplaires retournés. Nous avons investigué la révélation des patients aux médecins, la révélation aux enfants (par qui, à quel âge, etc.), le vécu des patients et des enfants, l'avis des praticiens sur le sujet de la révélation, de la connaissance des origines biologiques, de la maltraitance, leurs conseils, etc. Nous observons que 93 praticiens ont été les confidents de situations de paternité légales différentes de la paternité biologique ou d'un doute à ce sujet. D'après les médecins, les patients (les mères, les pères et les enfants) vivent généralement mal la situation de paternité particulière. La moitié des enfants concernés étaient informés de leur filiation atypique. La majorité des enfants informés se sentaient victimes. Une proportion élevée de problèmes affectifs et psychologiques était signalée parmi les enfants informés et non informés. A la question ci-dessus, nous avons observé une différence entre la réponse globale des praticiens consultés et la littérature psychologique et psychiatrique relative au secret des origines. Nous apportons également une réflexion sur la situation des enfants dont la filiation est particulière et sur une hypothèse de prise en charge de ces patients.
