The use of mosses and pine needles to detect persistent organic pollutants at local and regional scales.

Polycyclic aromatic hydrocarbons (PAHs) were analysed in mosses (Hypnum cupressiforme) and pine needles (Pinus sylvestris) collected in the Czech Republic between 1988-94 at a regional background site in Kosetice, south Bohemia (1988-94) and two industrial sources. One industrial site (sampled 1989-91) in middle Moravia, was near a factory producing PAHs, carbon black and phthalates, the other (sampled 1991-93) near a coal and gas fuel production plant in western Bohemia. Selected chlorinated pesticides and polychlorinated biphenyl congeners were also analysed in samples at the regional background site. This study clearly shows that vegetation sampling can be used to show spatial differences in the atmospheric burden of a range of persistent organic pollutants with differences in the mixtures of compounds reflecting differences in their regional or local use/atmospheric emission.

Comparison of extraction methods for polycyclic aromatic hydrocarbon determination in sediments

Different sample preparation methods for the determination of polycyclic aromatic hydrocarbons (PAHs) in lake and river sediments were compared and evaluated. Freeze‐dried sediment materials were e...

Project TOCOEN. The fate of selected organic pollutants in the environment I. Introduction

Project TOCOEN (Toxic Organic COmpounds in the ENvironment) is a new nontraditional research project of the Department of Environmental Studies, Purkyne University, Brno, Czechoslovakia and many other Czechoslovak research institutes and factories. The aim of this Project is understanding the fate of selected organic pollutants (PAHs, chlorinated pesticides, PCBs, PCDDs, PCDFs) in all parts of the environment, and modelling the fate of these compounds in the environment.

Project tocoen. The fate of selected organic pollutants in the environment—iv. soil, earthworms and vegetation 1988

The samples of soils, earthworms and vegetation (needles, lichens, mosses) were collected for the realization of Project TOCOEN (Toxic Organic Compounds in the ENvironment). The samples were collected from three TOCOEN model areas in Czechoslovakia—one city and two rural areas. The samples were analyzed for polycyclic aromatic hydrocarbons (PAHs), chlorinated pesticides (C1‐PEST) and polychlorinated biphenyls (PCBs).

The Spatial and Temporal Variations of Polycyclic Aromatic Hydrocarbons (PAHs) in Environmental Matrices in the Czech Republic

Abstract The paper is a review of the PAH emission inventories and the results of ambient air measurements of PAHs on regional a local level and determination of PAHs in other abiotic and biotic samples in the Czech Republic (CR). The main sources of polycyclic aromatic hydrocarbons (PAHs) in the country are associated with electric and thermal energy production, waste incineration, road traffic and some industrial processes (e. g. high-temperature coal carbonation, catalytic cracking of crude oil and aluminium production).

Project tocoen the fate of selected organic compounds in the environment part VII. PCBs, PCDDs and PCDFs in ambient air in Czechoslovakia — 1990

Abstract This study is a part of Project TOCOEN (Toxic Organic COmpounds in the ENvironment) and provide baseline atmospheric concentrations of PCBs, PCDDs and PCDFs in various parts of Czechoslovakia.

Project TOCOEN. The fate of selected organic pollutants in the environment III. Water and sediments 1988

Surface waters and bottom sediments were sampled for realization of Project TOCOEN (Toxic Organic Compounds in the ENvironment). The samples were collected from three TOCOEN model areas in Czechoslovakia—one city and two rural areas. The samples were analyzed for polycyclic aromatic hydrocarbons (PAHs), chlorinated pesticides (Cl‐PEST) and polychlorinated biphenyls (PCBs).

Project TOCOEN. The fate of selected organic pollutants in the environment II. Air and rainwater 1988

The samples of ambient air and rainwater were collected for the realization of Project TOCOEN (Toxic Organic Compounds in the ENvironment). Low‐ and high‐volume samples of ambient air were collected with polyurethane foam (PUF), rainwater samples were collected in aluminium vessels. The samples were collected from three TOCOEN model areas in Czechoslovakia—one city and two rural areas. The samples were analysed for polycyclic aromatic hydrocarbons (PAHs), chlorinated pesticides (Cl‐PEST) and polychlorinated biphenyls (PCBs).

Project Tocoen. The fate of selected organic pollutants in the environment. IX. A model source of PCBs, PCDDs and PCDFs

A model source of PCBs, PCDDs and PCDFs release into the environment was observed. The model source was the lorry producing factory LIAZ at Mnichovo Hradistě, where the used oil incinerators is located.
