“…The average concentration of all APs of each chain length (from phenol to C9) was also measured ( Table 2). The AP profile and relative concentrations in the PW obtained from Oseberg C for this study are similar to those measured previously in PW from the same platform (Boitsov et al, 2004(Boitsov et al, , 2007. The AP data also showed how the AP concentration in PW falls as the solubility in water decreased ( Table 2).…”

Produced water (PW) contains numerous toxic compounds of natural origin, such as dispersed oil, metals, alkylphenols (APs), and polycyclic aromatic hydrocarbons (PAHs). In addition, PW also contains many different chemicals which have been added during the oil production process. In the study described here, cod were exposed to real PW collected from an oil production platform in the North Sea. This was done in order to best recreate the most realistic field-exposure regime in which fish will be affected by a wide range of chemicals. The biological effects found in this study therefore cannot be assigned to one group of chemicals alone, but are the result of exposure to the complex chemical mixture found in real PW. Since APs are well known to cause endocrine disruption in marine organisms, we focused our chemical analysis on APs in an attempt to better understand the long-term effects of APs from PW on the biology of fish. In this study, cod were exposed to several concentrations of real PW and 17β-oestradiol (E(2)), a natural oestrogen, at different developmental stages. Cod were exposed to PW either during the embryo and early larvae stage (up to 3 months of age) or during the early juvenile stage (from 3 to 6 months of age). Results showed that, in general, APs bioconcentrate in fish tissue in a dose and developmental stage dependent manner during PW exposure. However, juveniles appeared able to effectively metabolise the short chain APs. Importantly, PW exposure had no effect on embryo survival or hatching success. However, 1% PW clearly interfered with the development of normal larval pigmentation. After hatching most of the larvae exposed to 1% PW failed to begin feeding and died of starvation. This inability to feed may be linked to the increased incidence of jaw deformities seen in these larvae. In addition, cod exposed to 1% PW, had significantly higher levels of the biomarkers vitellogenin and CYP1A in plasma and liver, respectively. No similar effects were seen in cod exposed to either 0.1% or 0.01% PW.

“…APs are natural components of crude oil (Ioppolo-Armanios et al, 1992), and as a result of their solubility in water high concentrations are still present in the aqueous phase after oil/water separation (Boitsov et al, 2007). Oil production platforms, therefore, release large amounts of APs into the seas via PW.…”

“…The groups of PAHs are known or suspect carcinogens [19,20]. APs and plasticizers like BPA and PEs are ubiquitous environmental contaminants that posse possible estrogenic properties [18,[21][22][23]. PCBs are banned for productions and utilization and can cause toxic responses include dermal toxicity, immunotoxicity, carcinogenicity, and adverse effects on reproduction, development, and endocrine functions [24].…”

In the present work, a sensitive, simple, and fast method with little sample handling has been developed for the determination of 34 semi-volatile organic xenobiotics from rain, sea and ground waters. The method is based on Headspace-Solid Phase Microextraction (HS-SPME) and Gas Chromatography coupled to Mass Spectrometry (GC-MS/MS). Sixteen Polycyclic Aromatic Hydrocarbons (PAHs), eight Phthalate Esters (PEs), six Polychlorinated Biphenyls (PCBs) and two Alkylphenols (APs) were quantitative analyzed in a single run. The best parameters for extraction were determined, including fiber type, sample volume, salinity and extraction time and temperature. In the optimized procedure, 15 ml of water sample was extracted using a 100 μm PDMS fiber in a 20 ml vial and adding 3 g of NaCl (final NaCl concentration of 20%) during 40 min at 80°C (with 10 min of previous equilibration time). A desorption time of 15 min was shown to eliminate carry-over. The method showed good linearity between 0.01 and 10 μgL -1 (r 2 from 0.987-0.999). Good precision (63-123%) and accuracy were achieved (1.1-21%). The Methodological Detection Limits (MDL) ranged from 0.00001-0.01364 µg L -1 . The method was successfully applied to real samples collected at Ensenada (Mexico). The proposed method represents an effectively and valuable tool for application in environmental water monitoring programs.

Performance of a New Geometry of Deoiling Hydrocyclones: Experiments and Numerical Simulations

A new geometry of liquid-liquid hydrocyclones is proposed seeking to perform the separation of oil emulsified in water. The hydrocyclone performance was investigated by means of a factorial experimental design (2 3 ) leading to a total of ten experiments. The results enabled the determination of empirical mathematical models that describe capacity, total separation efficiency, and flow ratio as a function of oil concentration in the feed inlet, operating pressure drop, and presence or absence of a vortex finder in the geometry. Numerical simulations were also carried out to further understand the flow field characteristics in the studied hydrocyclone.
