The Study of the Sterilization of the Indoor Air in Hospital/Clinic Rooms by Using the Electron Wind Generator.

(1) Background: Since exposure to airborne bacteria and fungi may be especially hazardous in hospitals and outpatient clinics, it is essential to sterilize the air in such rooms. The purpose of this study was to estimate the decrease in the concentration of airborne bacteria and fungi in the selected hospital and clinic rooms due to the work of the electron wind generator (EWG). (2) Methods: EWG is an air movement and air purification device using a sophisticated combination of electrode topology and specially designed high-voltage power supply.

The relationship between children's non-nutrient exposure to cadmium, lead and zinc and the location of recreational areas - Based on the Upper Silesia region case (Poland).

Introduction: The aim of the study was to identify the places that could pose a threat to children's health due to the significant concentration of heavy metals in the top layer of soil on which they actively spend their time.

Materials And Methods: The research material consisted of 144 topsoil samples from 10 randomly selected playgrounds and 10 sports fields located in two cities in Poland. The content of cadmium (Cd), lead (Pb) and zinc (Zn) in the analyzed samples was determined by atomic absorption using the INTEGRA XL ICP spectrometer with inductively coupled plasma.

PCDDs, PCDFs and PCBs in locally produced foods as health risk factors in Silesia Province, Poland.

Dioxins (PCDDs), furans (PCDFs) and polychlorinated biphenyls (PCBs) emitted into the environment can accumulate in foods and become a significant source of dietary exposure for consumers of these compounds. This study aims to assess the dietary exposure of the residents in a rural area of the Silesia region in southern Poland to PCDDs, PCDFs and PCBs. The goal is to estimate cancer and non-cancer health risks due to the consumption of foods of animal origin.

Is the soil quality monitoring an effective tool in consumers' protection of agricultural crops from cadmium soil contamination?-a case of the Silesia region (Poland).

The monitoring of soil quality should be a control tool used to reduce the adverse health effects arising from exposure to toxic chemicals in soil through cultivated crop absorption. The aim of the study was to evaluate the effectiveness of the monitoring and control system of soil quality in Poland, in terms of consumer safety, for agricultural plants cultivated in areas with known serious cadmium contamination, such as Silesia Province. To achieve the objective, the contents of cadmium in soils and vegetables in the Silesia administrative area were examined.

Preliminary study of possible relationships between exposure to PCDD/Fs and dl-PCBs in ambient air and the length of life of people.

There is a lack of studies on the impact of very toxic and persistent organic compounds as polychlorinated dibenzodioxins (PCDDs), dibenzofurans (PCDFs) and polychlorinated biphenyls (PCBs) on the population life expectancy. Preliminary studies on the relations between exposure to PCDD/Fs and dl-PCBs in ambient air and the length of life of residents of 12 cities (2 million people) in the Silesia province has been undertaken. The average length of life of inhabitants in 12 cities of Silesia province was calculated on the basis of register of deaths after excluding deaths caused by external causes and the concentration of PCDD/Fs and dl-PCBs were measured.

Long-term exposure to urban air pollution and the relationship with life expectancy in cohort of 3.5 million people in Silesia.

Air pollution is considered to be one of the most important environmental health determinants. The studies constitute an attempt to explain the role of air pollutants in the impact on the length of life of the 3.5 million people living in the cities of the Silesia province in Poland.

Environmental risks perception--a study of the awareness of families to threats in areas with increased health disorders in children.

Introduction: Children are at greater risk than adults to experience adverse effects from environmental agents. Significant neurological damage to children can occur even at very low levels of exposure. Reliable protection of children living in areas with high environmental hazards is not possible without their parent's' understanding of where, how and why children's exposures occur.

Scots Pine (Pinus sylvestris L.) Growth Suppression and Adverse Effects on Human Health Due to Air Pollution in the Upper Silesian Industrial District (USID), Southern Poland.

Air pollution emissions were not continually monitored in the Upper Silesian Industrial District (USID), southern Poland, and data is only available for the last 20 years. Long-lasting and severe tree ring reductions in pines growing 5-20 km north of the USID area recorded particularly high levels of air pollution emissions in the period 1950-1990. Especially high amounts of reductions and many missing rings were found in the period 1964-1981.

Risk assessment and risk communication in environmental health in Poland.

Efficient prevention activities can reduce disease, caused by environmental factors as well as costs to the health-care system, but it is impossible without understanding by the society of when, where, how and why exposures occur. Physicians and other health-care professionals may have an important role to play in communication of these potential dangers as the public requires information from knowledgeable and trusted sources about environmental risks and methods to avoid them. Epidemiological study in Poland shows that the health risk awareness in the society is not satisfactory and improvement of communication processes is essential to reduce individual risk factors.

Study of the health effects of long-term exposure to cadmium and lead in a region of Poland.

A region in Poland with a high concentration of lead (Pb) and cadmium (Cd) was used as a case study to look for the potential health consequences of chronic cadmium and lead exposure. The analysis of the incidence of cardiovascular diseases and neoplasms mortality were carried out and the mortality using SDR (standardized death rate) were compared with Cd and Pb pollution in each of 13 cities. To estimate the association between health effect and the pollutant concentration, the linear regression method was used.
