The supernatants were further cleaned-up and enriched by solid-phase extraction using octadecyl (C18)-bonded silica cartridges, then assayed by capillary gas-liquid chromatography with electron capture detection. The recoveries of eleven organochlorine pesticides (OCPs) from raw milks were quantitative, ranging from 90-110% at 10 times the limit of detection (LOD). The LOD ranged from 0.5 micrograms/l whole milk for alpha-hexachlorocyclohexane to 2.5 micrograms/l whole milk for 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane. The day-to-day variation of the method was evaluated over 7 days using 3 different pools of spiked cow milks (at the LOD, 5 and 10 times the LOD). The coefficient of variations (C.V.s) were 16 +/- 6, 10 +/- 2 and 9 +/- 3% (mean S.D.), respectively. The method showed no emulsion problems common with conventional non-polar solvent extraction, and the use of solid-phase extraction considerably reduced the sample clean-up process compared with the existing methods. The method also showed that OCPs in milk could be extracted quantitatively without extraction of total fat, and that OCPs spiked into cows milk could be used to construct calibration curves for human milk determinations.

For the determination of volatile organohalogen compounds direct aqueous injection (DAI) into capillary column and electron capture detector (ECD) were used. For the determination of volatile hydrocarbons purge and trap technique, sorption on solid sorbent (Tenax TA) followed by thermal desorption and GC-MS final determination were applied. Pesticides, polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyl's (PCBs) were determined after sorption on solid sorbent (C-18), solvent extraction (dichloromethane) and GC-ECD, GC-NPD and GC-MS analysis. Phenols were determined after sorption on solid sorbent (SDB.1. cartridges), solvent extraction (acetonitrile) and HPLC technique. Most of the compounds monitored were found to be present in selected sampling sites. This can indicate the contamination of the Gdańsk Bay with organic compounds originating from quite different sources. The problems which can be caused in the near future by the presence of organic pollutants should be a subject of special attention since a lot of organic substances tend to bioaccumulation and, even worse, due to persistence in the environment and lipophilic character also biomagnify in the food chain. The proposed new methods have been used successfully for the determination of organic compounds in water from rivers and sea.

The method is based on the microwave-assisted extraction (MAE) of food samples from an acetonitrile-water (95 + 5, v/v) mixture followed by SPE cleanup of the extracts and analysis by GC with an electron capture detector. MAE operational parameters, such as the extraction solvent, temperature, and time, were optimized with respect to the extraction efficiency of the target compounds from food samples with 10-13% fat content. The chosen extraction technique allows reduction of the solvent consumption and extraction time when compared with methods already used. Acetonitrile is a good extraction solvent for low-fat matrixes (2-20% fat content), such as fish samples, because it does not significantly dissolve the highly polar proteins, salts, and sugars commonly found in food and gives high recoveries of a wide polarity range of analytes. For purification, SPE using LC-Florisil was shown to be sufficient for the removal of coextracted substances. Recoveries > 78% with RSD values < 15% were obtained for all compounds under the selected conditions. Method quantification limits were in the 5-10 microg/kg range. The method was applied to the analysis of samples of herring (Clupea harengus) purchased at the local fish market. The method is rapid and reliable for the determination of organochlorine analytes in fish muscle.

Additionally pesticides enter the atmosphere through many different processes. Determination of pesticides content in the atmosphere is extremely important, because atmospheric transport is one of the pollution pathways, by which pesticides are transported and deposited in the areas far from their sources. Concentration level of pesticides is considerably lower in the atmosphere than in water or soil. Therefore, the analysis of atmospheric samples is much more complicated. In the case of atmospheric samples, it is necessary to apply an appropriate equipment to separate particulate matter from the air. The analytical method should consist of such steps as: sampling with isolation and preconcentration, extraction, extracts purification and final determination of the analytes under investigation.

The resin XAD-4 was selected for the pre-concentration of organics from water and the thermal desorption was carried out at 200 °C in a stream of purified argon. The compounds liberated were combusted in an empty quartz tube and the chlorides were determined by a coulometric argentometric titration to a pre-set potential. Good accuracy and precision were achieved both for solutions in distilled water and purified sea water. The average recovery was in the range 95–103%. The possibilities of thermal desorption in a stream of air and of storing the sorbent tube with organic compounds adsorbed on it were also investigated. This method was used successfully for the determination of volatile organic halogens in samples of tap, river and sea water.

Sparged air was introduced into the reactor environment. Titanium dioxide supported on glass, hollow microsphers served as the photocatalyst. Pesticides destruction ratio was evaluated and oxidation products were identificated by gas chromatography with thermionic specific detector (GC-TSD) and mass spectroscopy detector (GC-MS). The concentration of pesticides after reaction was determined in the liquid phase, in the solid phase (adsorbed on the photocatalyst) and in the gas phase. The experimental data indicates that pesticide removal with the gas phase was insignificant, therefore it was neglected in the assessment of the photodegradation efficiency. From 14% to 58% of investigated pesticides remained adsorbed on catalyst surface after photodegradation. High content of pesticides in the solid phase after reaction resulted from their low solubility in water and indicates significant adsorption ability of the pesticides by TiO 2 .

Developing additive substance abuse treatment programs for pregnant women is socially important and can help ensure the health of babies, prevent subsequent developmental and behavioral problems (i.e., from intake of alcohol or other additive substances such as methamphetamine, cocaine,or heroine) and can reduce addiction costs to society. Because women of childbearing age often abuse controlled substances during their pregnancy, it is important to undertake biomonitoring of these substances in biological samples taken from the pregnant or nursing mother (e.g., blood, urine,hair, breast milk, sweat, oral fluids, etc.), from the fetus and newborn (e.g., meconium,cord blood, neonatal hair and urine) and from bot...
