Opis:: The search for the best solutions to restore soil balance is essential for attaining a stable and sustainable agricultural development worldwide. This research, which makes a contribution to these investigations, focuses on four substances (two innovative ones: basalt flour, brown algal extract, and two classic soil improvers: finely ground barley straw and compost) which can potentially alleviate the inhibitory effect of Cd2+ on the soil environment. The following were analyzed: the activity of acid phosphatase and alkaline phosphatase, counts of Pseudomonas sp., cellulolytic bacteria, copiotrophic bacteria and copiotrophic spore-forming bacteria, and the yield of spring barley. Cadmium (Cd2+) was applied as CdCl2 · 2.5H2O in the following doses: 0, 4, 40, 80, 120, 160, and 200 mg Cd2+ kg-1 of soil. For a more complete assessment of the soil, its biochemical properties and the counts of microorganisms were scrutinized with the following indices: RS – soil resistance, R:S – rhizosphere effect and EF – fertilization effect of the contamination alleviating substances. It was found that alkaline phosphatase is more sensitive to cadmium contamination of the soil than acid phosphatase. Cadmium did not exert any inhibitory effect on the number of microorganisms present or the yield of spring barley. Cellulolytic bacteria were the least sensitive to stress associated with the accumulation of high cadmium doses in the soil, whereas copiotrophic bacteria were the most sensitive microorganisms to the above stressor. The ability of cadmium-polluted soil to restore homeostasis depended on the type of a soil improver and the level of soil contamination. Negative consequences of cadmium pollution were effectively mitigated by straw, but less so by brown algal extract and basalt flour.

Tytuł:: Deliberations on zinc - a trace mineral or a toxic element?

Opis:: The paper gives a comprehensive insight into the role of zinc in the biosphere. It reviews numerous functions of this metal at various levels of the organisation of ecosystems. An attempt has ben made to assess its importance as a microelement, while not neglecting its toxicity due to excessive accumulation of zinc in the environment. Zinc is a natural component of the Earth's crust, but in many places it has accumulated in amounts near or above the safe levels. Currently, the use of this metal is very broad, and therefore attention should be drawn to possible consequences arising from elevated levels of zinc in the environment. Dispelling controversies surrounding heavy metals is a necessary step for gaining systematic and wider knowledge on these elements. This in turn will create an opportunity for the development of strategies and subsequent actions undertaken by everyone, from individuals to major international industrial corporations, aimed at achieving homeostasis in an environment polluted with heavy metals. Increased levels of zinc can adversely affect microbiological and biochemical processes occurring in the soil and the development of plants, which has a negative impact on the quantity and quality of crops. Therefore, low bioavailability of heavy metals, including zinc, in agricultural land is a key to the stability of ecosystems and food security.

Opis:: Metale ciężkie, w tym także cynk, gdy dostaną się do gleby w nadmiernych ilościach, stanowią dość trwałe zanieczyszczenie, w przeciwieństwie do różnego rodzaju zanieczyszczeń organicznych, podatnych w większym lub mniejszym stopniu na degradację mikrobiologiczną. Mimo iż akumulacja metali ciężkich przez drobnoustroje jest procesem powszechnym, to nie do końca poznanym. Granice tolerancji nie są jednakowe i zależą od ich bioróżnorodności i czasu trwania imisji, a także właściwości fizykochemicznych gleby, jej struktury, zawartości materii organicznej, pH i pojemności kompleksu sorpcyjnego. Coraz częściej do oceny stanu zanieczyszczenia gleby wykorzystuje się metody biologiczne, w tym aktywność enzymów glebowych, i w nich należy upatrywać szybkiej diagnozy jakości gleb. Wskaźniki te mogą być jednak wykorzystywane tylko do oceny gleb zanieczyszczonych metalami ciężkimi, a są mało przydatne w ocenie jakości gleb zanieczyszczonych związkami organicznymi.
Heavy metals, e.g. zinc, present in soil in excessive quantities become quite persistent contaminants. Thus, they differ from organic pollutants, which can be degraded, to a various degree, by microorganisms. Although the accumulation of heavy metals by microorganisms is widespread, this phenomenon has not been thoroughly investigated. Tolerance limits are not uniform and depend on the biodiversity and duration of ambient concentration, as well as on the physicochemical properties of soil, soil structure, organic matter content, pH and sorptive complex capacity. Soil contamination is more and more frequently assessed with biological methods, by testing for example the activity of soil enzymes. Such assays, however, can be used to evaluate the quality of soils contaminated with heavy metals, but are less useful for testing soils polluted with organic compounds.

Opis:: The increasing resistance of community and hospital acquired bacterial strains has become a challenge to the current health policy in Poland. Although some bacteria are known to have a peculiar resistance towards a given agent, antibiotics have a well-established position in clinical practice and are broadly available in our lives. The universal access to antimicrobial therapy and its overuse have created an issue of previously susceptible bacteria now presenting antibiotic resistance. All bacteria that survive antibiotic treatment, continue growth and reproduction. This phenomenon is also observed in livestock rearing. An inadequate implementation of antibiotic therapy leads to the transfer of resistant bacterial strains into the environment of people, who eat products of animal and plant origin. Moreover, the non-compliance to law in terms of antibiotics added to animal fodder or negilgence of withdrawal periods seems to further exacerbate the situation. Various research projects conducted in Poland and elsewhere have demonstrated that antibiotics produce an immunosuppressive effect, which exposes both humans and animals to different infections. Antibiotics also interfere with the growth of many microorganisms, recognized as part of the human and animal physiological microflora, as a result of which dysbacteriosis may develop. In order to limit the use of antibiotics in animal husbandry, research should be focus on finding alternative agents based on plant extracts that undergo biodegradation.
