The products of honey bees can be used as indicators and monitors of a variety of environmental pollutants because of the bees� ability to collect materials that reflect their immediate environmental conditions. Human activities produce more waste and administrate the pesticides, the amounts and toxicity of which often exceed the environment�s homeostatic capacity to cleanse itself, and this is constantly transforming due to intensive agricultural practices necessary to increase food production as human population grows. The main sources for contamination of honey with heavy metals are represented by placing hives near urban areas with heavy car traffic, or industrialized areas and the use on the entire circuit of production, objects or containers made of materials unsuitable (unacceptable). For that reason regular monitoring of the environment is so important. Honey bees, thanks to their morphological features, and also bee products are regarded as good indicators of environmental pollution by toxic substances, be these heavy metals, radioactive elements or persistent organic pollutants such as pesticides. Consequently, it is important to estimate the environmental fate and Eco toxicological effects of these different xenobiotic. Honey bees (Apis mellifera L.) have been used as biological indicators of Plant Protection Products (PPPs) in two intensely cultivated in areas of Neamt County, Romania. This area is representative for the pre-mountain and mountain zone of Romania. The stratified sample has been face-to-face interviewed in 2016 regarding the data from the year 2015. The total consumption specific for the honey production was about 628 MJ hive-1, and the energy output reached 235 MJ hive-1, determining an energy productivity of 0.030 kg MJ-1 and an energy use efficiency of 0.37. Specific energy amounted 33.3MJ kg-1 due to the inefficiency of traveling during the apiaries movements and the inappropriate correlation between the apiaries size and the zonal melliferous potential. In this paper available literature data and information on the morphological features of the honey bee, the utilization of the honey bee and its products as indicators of environmental pollution, and a historical outline of some of the legislation relating to beekeeping have been critically compared and discussed.

Abstract The Index of Atmospheric Purity (IAP) is a popular tool used for the assessment of air quality in polluted urban areas, on the basis of phytosociological data of epiphytic lichen communities. We hypothesized that this indicator could also be used in less polluted forest areas to determine the quality of ecological conditions for lichens. The aim of the present study was to verify the use of IAP method in the assessment of environmental pollution, and alternatively for the assessment of general ecological conditions in protected mountain forests of Gorce National Park (Polish Western Carpathians) based on the epiphytic lichen biota associated with Picea abies. The spatial distribution of IAP values on monitored sites in GNP was compared with: 1) spatial distribution of accumulated sulfur, nitrogen, selected heavy metals, and total heavy metals in Hypogymnia physodes thalli in 1993 and 2018 (30 sites), 2) mean ecological indicator values characterizing species requirements for light (L), substrate reaction (R) and nutrients (N), in 1993, 2013 and 2018 (33 sites). Generalized linear model and redundancy analysis were performed for disclosing most influencing factors affecting lichen communities. The study revealed a few negligible relationships between IAP values and accumulation of such elements as Ni, Mn, Cd, and Cr in both monitoring periods. Simultaneously, IAP can be useful for the identification of forest areas with a high degree of naturalness.

Isolation And Characterization

Mining industry is a source of wealth but also of environmental pollution in Peru. In this study 12 colonies of actinomycetes were isolated in acidic cultures from mineral ores and concentrates from mines of the Peruvian highlands. The isolates were characterized phenotypically by microscopy and growth at different conditions as pH tolerance, temperature, and sodium chloride, heavy metals resistance; ferrous iron and thiosulfate oxidation. All isolates were identified as actinomycetes based on their cultural and spore characteristics. Most of the isolates were able to grow at 8 - 45°C and pH 4 - 11. 60% of isolates grew at 10% NaCl but none of them growth at 13%. Iron oxidation was shown by 60% of isolates at pH 4, but only 25% were able to oxidize iron at pH 2. Thiosulfate oxidation was not detected in any isolate. Most of the isolates showed capacity to grow in medium with 200 ppm of Pb, Fe, Zn and 100 ppm of Cu. All of the physiological characteristics found in this work indicate the potential of these isolates as source for bioremediation and bioleaching.
