“…There are many different analytical methods for the determination of BPA and 4-NP in aquatic environment, plastics and soil, including GC-MS, LC-MS and HPLC-FLD [7][8][9][10][11]. However, only a few analytical methods for the determination of BPA or 4-NP in biological samples were reported.…”

“…Procedures described in the methods of APHA (1998) were used in the preparation of water samples while the metal concentrations were determined by Atomic Absorption spectrophotometry (buck scientific 200A model). Gas chromatography mass-spectrophotomery (GC-MS) was used in the hydrocarbon analysis (Law and Biscaya, 1994;Helaleh et al, 2001).…”

The aim of this study was to assess some heavy metals (Cr, Ni, Cd, Pb, Zn and Cu) and hydrocarbon concentrations of Azuabie creek using the Okujagu creek as a control location. Seventy two samples were collected from four stations (AZ1, AZ2, AZ3 and OK) in six months (July-December 2016). Samples were analyzed using AAS and GC spectrophotometry while ANOVA and PCA were used for data analysis.The hydrocarbons (THC, 0.3 ± 0.07-84.6 ± 28.85 mg/l, TPH,0.07 ± 0.03-45.20 ± 13.88 mg/l & PAH, 0.001 ± 0.0003-0.384 ± 0.104 mg/l) were generally higher in Azuabie creek and showed increased concentration over time with significant difference (p<0.001) between locations and also between months. The increase in hydrocarbon level is due to oil bunkering and other anthropogenic activities in the study area. The concentration of Cr, Ni, Cd, and Pb generally exceeded WHO and USEPA limits in water while those of Zn and Cu fell below such regulatory limits. Site discrimination by PCA showed AZ1 & AZ2 as most dissimilar stations traceable to higher contaminant levels associated with such sites. In conclusion, the variables within Azuabie creek showed higher contaminant level compared to the control creek. Complete isolation of each site examined indicates dissimilarity in the water quality with respect to contaminant level within the creek hence regular monitoring is needed to detect water quality changes.

“…When sludge containing APEOs is to be analysed, four main extraction techniques are available: Soxhlet extraction [23,24], ultrasonically assisted extraction [25,26], microwave-assisted extraction (MAE) [27,28] and pressurized fluid extraction (PFE) [14,15]. Pressurized fluid extraction is also known as pressurized liquid extraction or accelerated solvent extraction and is the main extraction technique for APEOs in solid matrices [4].…”

Trace-level analysis of alkylphenol polyethoxylates (APEOs) in wastewater containing sludge requires the prior removal of contaminants and preconcentration. In this study, the effects on optimal work-up procedures of the types of alkylphenols present, their degree of ethoxylation, the biofilm wastewater treatment and the sample matrix were investigated for these purposes. The sampling spot for APEO-containing specimens from an industrial wastewater treatment plant was optimized, including a box that surrounded the tubing outlet carrying the wastewater, to prevent sedimented sludge contaminating the collected samples. Following these changes, the sampling precision (in terms of dry matter content) at a point just under the tubing leading from the biofilm reactors was 0.7% RSD. The findings were applied to develop a work-up procedure for use prior to a high-performance liquid chromatography-fluorescence detection analysis method capable of quantifying nonylphenol polyethoxylates (NPEOs) and poorly investigated dinonylphenol polyethoxylates (DNPEOs) at low microg L(-1) concentrations in effluents from non-activated sludge biofilm reactors. The selected multi-step work-up procedure includes lyophilization and pressurized fluid extraction (PFE) followed by strong ion exchange solid phase extraction (SPE). The yields of the combined procedure, according to tests with NP10EO-spiked effluent from a wastewater treatment plant, were in the 62-78% range.
