Holoubek I.

Cent Eur J Public Health 2000, 8(Supplement):S4-S5

Organic substances that are persistent, bioaccumulative and have toxic characteristics likely to cause adverse effects on human health or have environmental effects are called PBTs (Persistent, Bioaccumulative, Toxic substances). The report "Persistent, Bioaccumulative and Toxic Chemicals in Central and Eastern European Countries - State-of-the-art Report" was prepared by a group of scientists from the Czech Republic, Slovakia, Poland and Estonia and was published on the Internet (http: inverted question markrecetox.chemi.muni.cz/).

Polychlorinated naphthalenes in soil, sediment, and biota collected near a former chloralkali plant in coastal Georgia, USA

Kannan K., Blankenship A.L., Giesy J.P., Imagawa T.

Cent Eur J Public Health 2000, 8(Supplement):S10-S12

Concentrations of total polychlorinated naphthalenes (PCNs) as high as 23 µg/g, dry wt, were found in sediments contaminated by the disposal of wastes from chlor-alkali processes. Concentrations of total PCNs in blue crab, fish and birds were 3- to 5-orders of magnitude less than that in sediments. The profile of PCN congeners in biota was predominated by tetra- or penta-chloronaphthalenes, while hepta- and octa-chloronaphthalenes were dominant in sediments. The 2,3,7,8-tetrachlorodibenzo-p-dioxin equivalents (TEQs) estimated for PCNs in sediments and biota were greater than those reported for PCBs, PCDDs or PCDFs. These results suggest that...

The evaluation of dioxin emissions from pilot scale incineration of organochlorine compounds

Cent Eur J Public Health 2000, 8(Supplement):S12-S13

Formation of the dioxins was investigated in case of two fuel types (kerosene-dichlorobenzene and kerosene-dichloroethane) on a pilot scale liquid waste incinerator. It was determined the effect of the molecule structure (aromatic, aliphatic) and Cl content (1, 3 and 6 %) of the liquids and the combustion parameters (O₂ content, residence time and temperature). In some experiments particulate matters (fly ash and soot) were injected.

Hennig B., Slim R., Toborek M., Malecki A., Robertson L.W.

Cent Eur J Public Health 2000, 8(Supplement):S18-S19

Our findings suggest that exposure to specific environmental contaminants can trigger diseases of the vasculature, e.g., cardiovascular disease. In addition, high-fat diets may potentiate and diets high in antioxidant nutrients may protect against PCB-mediated endothelial cell dysfunction. Our data give an insight into the potential use of vitamin E and related antioxidants to limit PCB-mediated cell injury. These studies are significant for providing new insights into potential nutrition interventions in diseases that can be induced by the toxicity of PCBs and other halogenated compounds.

Organochlorine pesticides as endocrine disruptors in wildlife

Guillette L.J Jr.

Cent Eur J Public Health 2000, 8(Supplement):S34-S35

Many xenobiotic compounds introduced into the environment by human activity have been shown to adversely affect wildlife. The ubiquitous distribution of many contaminants and the documented, nonlethal, multigenerational effects on the reproductive, endocrine, and immune systems have lead to concerns that wildlife worldwide are affected. The reproductive disorders reported to date in wildlife include reduced fertility, reduced hatchability, reduced viability of offspring, impaired hormone secretion or activity and modified reproductive anatomy. The endocrine system exhibits an organizing effect on the developing embryo. Thus, a disruption of the normal...

Primary mono-layer cell cultures as model system for studying of environmental toxic agents: organochlorine compounds

Soós K., Valkusz Z., Vetró O., Juhász A., Petri A., Molnár G., Molnár J., Gálfi M.

Cent Eur J Public Health 2000, 8(Supplement):S35-S36

Organic pollution of water and soil has various harmful effects on biological systems (1). Chlorine substituted benzol compounds are one these xenobiotic substances, which are toxic to the environment (2). They can also accumulate in plant and animal tissues (3), which provides ample reason to study the effects of sublethal doses of chloro-benzols on various cell cultures. In this study the toxic effects of chloro-benzols were investigated on avian fibroblast and mammalian hepatocyte cultures. The fibroblast cultures were prepared from eggs preadapted to chloro-benzol during a fourteen-day-long incubation period. The Wistar rat hepatocyte monolayer...

Chloride ions formation during degradation of organochloride compounds using TiO₂ deposited on glass microspheres

Cent Eur J Public Health 2000, 8(Supplement):S37-S38

Aqueous solutions containing 200 mg/dm³ of p,p'-DDT and methoxychlor were photodegraded for 60 min in UV/TiO₂/O₂ system and chloride ions concentration and pH were measured. From 60 to 80 % of the investigated pesticides were eliminated after treatment. Over 27 % of chlorine atoms were splitted off for methoxychlor and 10 % for p,p'-DDT. The experimental data suggest, that chlorine atoms were removed from the -CCl₃ moiety but the chlorine atoms bound to aromatic ring were left intact at this step of photodegradation.

Polychlorinated biphenyls (PCBs) are persistent, bioaccumulative and toxic contaminants in the environment. Individual PCB congeners exhibit different physico-chemical properties and biological activities which result in different environmental distributions and toxicity profiles. The variable composition of PCB residues in environmental matrices and their different mechanisms of toxicity, complicate the development of scientifically based regulations for the risk assessment. Various approaches for the assessment of risks of PCBs have been critically examined. Recent developments in the toxic equivalency factor (TEF) approach for the assessment of...

The improper management of large quantity of chemical waste of a chemical plant caused considerable soil contamination on a temporary hazardous waste disposal site. Initial and action-oriented exposure and health risk assessment was carried out in early 90's. The dominant contaminants were tetrachlorobenzenes (TeCBs), pentachlorobenzene and hexachlorobenzene (HCB). Concentration of TeCBs in top soil layer and vadoze zone exceeded several g/kg. After taking appropriate technical measures quantitative health risk assessment was performed for the target population living in the surrounding settlements.

Lehotzky K.

Cent Eur J Public Health 2000, 8(Supplement):S55-S56

A complication is given on the elements of risk assessment of hazardous neurotoxic pesticides, using data from human epidemiological studies, as well as animal experiments. Well-controlled laboratory studies of neurotoxicity have the potential to provide adequate exposure and effect data for accurate hazard identification. Using animal models of neurotoxicity as highly sensitive behavioral and neurophysiological methods as a function of doses, provide data for human low dose extrapolation by mathematical models. To reduce risk ("risk management") some examples are given how to handle properly neurotoxic pesticides with high risk.

Research tends to center on the individual exposed to endocrine disruptors, frequently using a disease centered medical model for evaluative purposes. Pesticides, like many other contaminants, disrupt the endocrine system. A normative growth and developmental model was used to evaluate four- and five-year-old Mexican children living in agricultural areas relying on the use of pesticides and compared the children to those living in a non-agricultural community. The purpose was to determine if the children of any given community were at risk from exposure, in contrast to identifying specific children with multiple deficits. Anthropological methods were...

The social concern about polycyclic aromatic hydrocarbons (PAHs) is due to the awareness that several of them are carcinogens and are present in polluted air. Several epidemiological investigations have tried to assess the influence of air pollution on the incidence in the population (1). Some authors have suggest that 1-10 % of the incidence of lung cancer is caused by air pollution (2, 3). Several sources, e.g. traffic, oil heating, wood stoves, industry may contribute PAHs to the air pollution. Therefore continuous air pollution control applying selective and precise analytical procedures is needed. The submitted work presents results of examination...
