This article presents various aspects of the use and evaluation of geochemical background for different environmental media with a brief discussion on the origins, historical and present context, and application of this and other related terms. This subject has become one of the most crucial issues in geochemistry and environmental sciences during the last few years because of its application to environmental protection, land management, ecotoxicology and geochemistry. Three approaches (methods) of geochemical background evaluation are discussed: (i) direct, (ii) indirect, and (iii) integrated. In response to a strong need to reduce a large number of methods applied to background assessment, a plausible methodology based on archival data, including the results derived from determinations of Mn, Pb, Zn for quartzites, soils and Pinus sylvestris needles, from the Holy Cross Mountains (Świętokrzyskie Mountains, south-central Poland) has been proposed. This methodology belongs to the integrated approach to the background evaluation. Samples were collected in relatively pristine areas and statistical data analysis (iterative 2σ-technique) was used to eliminate outliers from the original datasets.

Aluminium is an element commonly occurring in nature, the third most abundant in the earth's crust after oxygen and silicon. It forms numerous mineral and organic complexes, characterised by different degrees of hydration. Its easy transition from solid to liquid phase and high solubility in acid environment are decisive factors for its important function in the environment. Until recently, aluminium was considered harmless for the human organism as it is readily excreted through urine. However, studies of environmental toxicology conducted in recent years indicated that aluminium could be a cause of many diseases in humans, animals and plants. Acid rains and increasing acidification of the environment induced water and soil pH changes which resulted in the mobilisation of toxic aluminium ions which in turn evoked many unfavourable alterations, such as plant poisoning, forest drying, crop reduction, vanishing of water fauna, and numerous disturbances in the function of human and animal organisms. Aluminium can be found in many food products and feed for animals. In this way it enters the organism and accumulates in various tissues. Although the mechanism of toxic aluminium actions on humans has not been elucidated yet, prophylactic action should be undertaken aimed at limiting the contact of humans with aluminium. Most of all, it should be eliminated from food, food additives and medicines. We should avoid tools, kitchen utensils and appliances made of aluminium as well as aluminium wrappings and containers.

Emission of light as a result of biochemical activities of some living bacteria Vibrio fischeri (in the past known as Photobacterium phosphoreum) makes it possible to monitor environmental changes in ecosystems. Toxicity testing as an international standard operating procedure based on the use of this method has already been accepted. The bioluminescent test offers a rapid, simple and sensitive method to test a wide spectrum of chemical substances and environmental samples including water, wastewater, sludge extracts, etc. In this study, aimed at characterising and comparing bioluminescent properties, four different bacterial strains were cultivated in four different liquid mediums and temperature conditions. The bioluminescent intensity of bacterial suspensions was measured using a laboratory BioOrbit 1253 luminometer during bacteria culture. Based on obtained results and mathematical calculations of RLU (relative luminescent units) values strain Photobacterium phosphoreum + NCBE medium were indicated as the variant demonstrating proper bioluminescence intensity and characteristics most suitable for further applications.

Some methods of artificial intelligence are evaluated in relation to development of medical elementology and primary prevention of health hazards related to antropogenic changes in the natural environment and the human food chain, diet, etc. Searching for a new paradigm of the cross-disciplinary system approach to nutritional prevention of excess or deficiency of some elements is very time- and cost-consuming task. Using artificial intelligence methods we obtained interesting conclusions on the basis of apparently fully exploited experimental data. Artificial intelligence (data mining and automatic knowledge discovering in particular) seems to be useful for developing interdisciplinary studies on medical elementology focused on application of scientific and technical progress for early detection of environmental health hazards related to excess or deficiency of selected elements in the natural environment, trophic chains and endoecological aspects (referring to possible inbalance of the basic homeostatic system). This cooperation was initiated by the foundating members of the International Union of Elementologists in New Delhi in 1983 and developed by a series of case studies, international conferences and monographs. Integration of studies in ecotoxicology, human ecology, environmental health with application of progress in informatics and environmental biotechnology is promising for more effective protection of health of consumers connected with changes of elements in the human diet and body (including primary prevention of some diseases of civilization).

The paper presents some aspects of relations between modern plant protection of apple orchards and ecotoxicology. Based on significant similarity of the shape and size of apple and tomato fruits the relation between the doses of active ingredients of plant protection products and their residue levels immediately after treatment was derived for the apples and then quality indices and the risks for human health were estimated. It was found that many of the currently in force MRLs need to be revised and the exposure of consumer should not exceed the acceptable daily intakes (ADIs) and acute reference doses (ARfDs) for pesticide residues.

With the development of toxicology as a science, the second half of the 20th century saw the establishment of scientific societies, such as the International Society of Ecotoxicology and Environmental Safety (SECOTOX), the Federation of European Toxicologists and European Societies of Toxicology (EUROTOX), the Polish Society of Toxicology, and the European Society of Toxicologic Pathology (ESTP). This study describes their development, organizational structure and mission. The scope of their interest, in addition to toxicology, also includes ecotoxicology, which protects the natural environment and public health.

W pracy przeanalizowano przydatność dla oceny kontaminacji roślin następujące współczynniki ekotoksykologiczne: współczynnik specyficznej kumulacji, wskaźnik względnej koncentracji, współczynnik wzbogacenia, wskaźnik fitokumulacji. Zawartość Ni, Pb, V, Zn, Co, Cr, Cu, Mn oznaczono metodą fluorescencyjnej spektrometrii rentgenowskiej jako bardziej dokładną i tańszą metodą w porównaniu do metod emisyjnych. Okazało się, że w kompleksowych ocenach kontaminacji i kumulacji metali przydatne są wszystkie badane współczynniki, jednak największe znaczenie przypisuje się interpretacji wartości współczynnika specyficznej kumulacji i wskaźnika względnej koncentracji.

The response of soil microflora to increasing concentration of three pesticide preparations containing diazinon (insecticide), linuron (herbicide) and mancozeb + dimethomorph (fungicide) as an active substances, was determined under laboratory conditions. All pesticides were applied at three different dosages, i.e. 7, 35 and 700 mg kg⁻¹ soil for the insecticide, 4, 20 i 400 mg kg⁻¹ soil for the herbicide and 15, 75 and 1500 mg kg⁻¹ soil for the fungicide mixture. The lowest dosages corresponded to the maximum predicted environmental concentration (PEC) of pesticides applied in field conditions, while the other dosages were the multiplicities of PEC. After 1, 14 and 28 days of experiment the numbers of heterotrophic bacteria, fungi and bacteria involved in nitrogen transformation (nitrifying, denitrifying and N₂ -fixing bacteria) was estimated. The numbers of colony forming units (CFU) of respective groups of microorganisms were determined on selective media by means of the serial dilution technique and the spread plate method. The plate-count data indicated that pesticide used affected the numbers of tested microbial groups. All chemicals stimulated the numbers of heterotrophic bacteria and fungi at the higher dosages. However, the reverse effect was detected at the beginning of the experiment. In turn, bacteria involved in nitrogen turnover, particularly N₂ - fixing and nitrifying bacteria, were the most sensitive to the tested pesticides and their numbers were significantly reduced on each time-point. This great susceptibility of these physiological groups of microorganisms predispose them to be warning biomarkers for the side-effects of environmental pollution caused by chemicals.
