“…In these particular conditions, the fluorescence or phosphorescence spectra showed a remarkable vibrational resolution so that even very similar isomers can be distinguished by this method. Several groups developed and applied Shpol'skii spectrometry to a variety of PAHs in several environmental samples, such as crude oils, sediments and fish tissues [59,60], marine sediments [61], river natural waters and sediments [62], and lake sediments [63]. The possibility of utilizing Shpol'skii fluorescence and phosphorescence spectrometry for determination of mutagenic amino-and nitro-substituted PAHs in environmental samples was also critically investigated by Kozin et al [64].…”

“…The development and application of different fluorescence methods to the study and quantitative analysis of various PAH-contaminated environmental matrices, including soils and sediments [63,65,66,67], living organisms [68] and air [69], have been reported. For example, Hawthorne et al [66] developed a simple field-portable method based on in situ sampling with solid-phase microextraction (SPME) coupled with laser-induced fluorescence (LIF) for determining the total dissolved PAHs in sediment pore water.…”

The analytical performances and applications of various luminescence spectrometric methods to the study and determination of pollutants present at low levels in the environment are reviewed for the last two decades (1990 – 2010). The first part concerns luminescence stationary systems, including fluorescence, photochemically-induced fluorescence, phosphorescence and related luminescence methods. In the second part, the combination of these luminescence methods with flow techniques such as high performance liquid chromatography (HPLC), capillary electrophoresis (CE) and flow injection analysis (FIA) for the detection and determination of environmental pollutants is investigated. A part of the review is also devoted to the usefulness of organized supramolecular systems, such as micellar media, cyclodextrins and calixarenes, for improving the efficiency of luminescence methods.

This study was designed to assess the contamination of a very special lake, Lake Baikal in Siberia, and two big lakes, Ladoga and Onega in the European part of Russia, by polycyclic aromatic hydrocarbons (PAHs). PAH compounds were analyzed by HPLC and the target PAH, benzo[a]pyrene (BaP), by using the spectral-luminescence (Shpol'skii) method. Elevated levels (to 96 µg kg −1 ) of BaP in sediments of Lake Baikal reflected proximity to potential sources of emission, situated either on shore (a paper and pulp mill in Baikalsk) or upstream river systems. The concentration of BaP in sediments decreased with the distance from outlet and the depth. The sediment samples contained several representatives of PAHs. The total content of identified compounds reached 873 µg kg −1 (less than four nuclear representatives not included). Dominating heavy PAHs wereThe authors thank E.

Kirso et al. of northeastern Baikal was more than two times less than that for the southern part of the lake and corresponds to the background level. The BaP levels estimated for sediments close to paper and pulp mills of the Lake Ladoga exceeded 160 µg kg −1 , being two orders of magnitude higher than that for other areas of these lakes. The contamination of sediments of Lake Onega by PAHs is affected by pulp and paper mills as well as other sources. Our results clearly demonstrate the contribution of specific industrial sources like paper and pulp mills to the content of PAHs in the Baikal, Ladoga, and Onega water ecosystem.

Start up of the Baikal Pulp and Paper Plant (BPPP) in 1965 posed the problem of preserving the ecosystem of the Lake Baikal most urgently. Baikal was included on the UNESCO World Heritage List in 1996. Despite the executive orders directed at protect ing the ecological system of Lake Baikal, by reducing the anthropogenic influence on the ecological system of the lake that was developed in the USSR and Rus sian Federation, great success was not achieved. The lake is still polluted by substances from the river, atmo sphere, and, over 50 years, from waste discharge.Since the first year of the plant's existence, the Hydrometeorology and Environmental Monitoring Agency has monitored the waters of the lake in the area of the plant, and in 1969 it developed a system of permanent hydrochemical, geochemical, and hydro biological monitoring that incorporates the water sys tem, bottom sediments, atmospheric precipitation, and rivers flowing into the lake. Studies were carried out with use of several hundred stations located over the lake and on its northern and southern banks (impact area of the Baikal Amur railway) in the Selen ginsk shallow waters at background points where pol lution was relatively weak.Development of chemical analyses of complex organic compositions allowed scientists to make the first determinations of polycyclic hydrocarbons in the water of the lake, waste waters of the plant, and bottom sediments since the 1980s.The main objective of monitoring is to determine the total concentration of the PAH and benz(a)pyrene, the most toxic PAH, which is the most dangerous for the lake environment. The latter is an indicator in the waste waters of the plant, water of the lake, and bottom sediments in the area of the waste water discharge of the BPPP (polygon). Benz(a)pyrene is not the main polluting substance in the area of anthropogenic influ ence caused by waste waters from the sulfite cellulose industry of the plant on the ecological system of the lake. However, benz(a)pyrene is formed directly in the process of thermal processing of wood under tempera tures of 300-400°C , and in the course of monitoring, it is an important indicator of pollution of bottom sed iments in the described polygon of the plant [1].Samples of bottom sediments in the area of the waste water discharge of the plant in the polygon with area of 20 km 2 were collected at 9-40 stations with use of the Ocean 0.05 dredge (made of stainless steel) from the surface layer of bottom sediments (pelogenous) at a depth of 20-500 m. Samples were placed into plastic pockets and immediately delivered to the laboratory. Then samples were dried at a temperature of 105°C and stored at room temperature before the analyses. Polycyclic aromatic hydrocarbons were extracted from the samples of bottom sediments with use of benzol over 8 hours in the Soxhlet device. Benzol was distilled off with the use of a rotary evaporator, and extraneous impurities were removed from the residue with use of the method of thin layer chromatography.
