Determination of semivolatile organic compounds in environmental samples by gas chromatography/mass spectrometry after extraction by cyclic steam distillation.
A method was developed for the multiple determination of semivolatile organic compounds found in groundwater, river water, seawater, sediment, and soil. Forty standard compounds were determined: n-alkenes, cycloalkanes, aromatic hydrocarbons, and polycyclic aromatic hydrocarbons. The compounds were isolated from water and soil samples by using an essential oil distillator (cyclic steam distilla...
متن کاملAre Endocrine Disrupting Compounds a Health Risk in Drinking Water?
There has been a great deal of international discussion on the nature and relevance of endocrine disrupting compounds in the environment. Changes in reproductive organs of fish and mollusks have been demonstrated in rivers downstream of sewage discharges in Europe and in North America, which have been attributed to estrogenic compounds in the effluent. The anatomical and physiological changes i...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Determination of selected endocrine disrupting compounds in human fetal and newborn tissues by GC-MS.
Endocrine disrupting compounds (EDCs) include organochlorine pesticides (OCPs), organophosphate pesticides (OPPs), carbamate pesticides, and plasticizers, such as bisphenol A (BPA). They persist in the environment because of their degradation resistance and bioaccumulate in the body tissues of humans and other mammals. Many studies are focused on the possible correlation between in utero exposu...
