TL;DR: In this article , the authors developed a descriptive analysis (ANOVA) and forecasting regarding cattle, sheep, goats and pigs in Romania and showed that these numbers will continue to decrease considerably both in the Bucharest-Ilfov region and in the Romanian mountain regions.
Abstract: The paper develops a descriptive analysis (ANOVA) and forecasting regarding cattle, sheep, goats and pigs in Romania. The data simulated in SPSS, taken from Eurostat, show that these numbers will continue to decrease considerably, both in the Bucharest-Ilfov region and in the Romanian mountain regions. The general situation of mountain agriculture shows similar trends to Romanian agriculture. At the national level, the arable surface has been reduced in stages in the last three decades, a decrease mainly due to the change of extensive agricultural methods (grazing, spontaneous flora) with intensive ones (stable, controlled flora). Following the national agricultural trend, mountain agriculture after 1990 changed its structure and dimensions (such as cattle, production and mountain producers, mountain entrepreneurship, etc.). Some aspects remained quantitatively unchanged, such as the large number of individual holdings and the high share of agricultural land use. In this context, public and private entities must act jointly for the valorization of mountain ecosystems by controlling the pollution caused by the numerous individual exploitations. The mountain ecosystems in the Romanian area influence the national agricultural productivity, valuing the mountain product at the highest levels. Whether it is alpine meadow ecosystems, including coniferous forests and interpenetration zones between high and mid-mountains, low-mountain ecosystems, or high- and mid-hill ecosystems, the ultimate goal of pollution reduction research and action must be the same, respectively protecting the mountain area.

TL;DR: A review on environmental biomonitoring is presented, followed by an overview on well-known natural species used as passive samplers and known as biomonitors, which were widely used in recent research as reliable monitors for environmental pollution.
Abstract: The continuous discharge of diverse chemical products in the environment is nowadays of great concern to the whole world as some of them persist in the environment leading to serious diseases. Several sampling techniques have been used for the characterization of this chemical pollution, although biomonitoring using natural samplers has recently become the technique of choice in this field due to its efficiency, specificity, and low cost. In fact, several living organisms known as biomonitors could accumulate the well-known persistent environmental pollutants allowing their monitoring in the environment. In this work, a review on environmental biomonitoring is presented. The main sampling techniques used for monitoring environmental pollutants are first reported, followed by an overview on well-known natural species used as passive samplers and known as biomonitors. These species include conifer needles, lichen, mosses, bees and their byproducts, and snails, and were widely used in recent research as reliable monitors for environmental pollution.

TL;DR: It could be concluded that the biomagnetic approach could serve as a comparatively fast and low-cost method to detect highly polluted urban areas with selected heavy metals, particularly the areas which are under the influence of anthropogenic and other traffic-related sources.
Abstract: Atmospheric deposition particles are fine-sized having a high adsorption capacity. Therefore, they can easily transfer the contamination to other areas. Plants can absorb certain pollutants using their leaves and then accumulate them in their biomass. In this study, the spatial and temporal variability of air pollution was assessed using pine needles as the bioindicators of atmospheric pollution. The magnetic susceptibility (MS) at low and high frequencies (χlf, χhf) and the concentration of selected heavy metals of pine needles (Pinus mugo) were estimated in order to address the possible relationships between needles' MS and the heavy metal concentration in the city of Isfahan, central Iran. In addition, the relationship between the heavy metal concentration of pine needles and that of the atmospheric dust was examined using the published data. Tree pine needles were monthly sampled, from April to December 2015 (T1-T9), during 9 months, from 30 different sites in the Isfahan city. There were two treatments including washed + unwashed (WU) and washed + washed (WW). The heavy metal total concentrations including Zn, Fe, Cu, Co, Pb, and Ni were measured. The mean concentrations of Fe, Zn, Pb, Cu, Ni, and Co were 80.4, 3.9, 1.8, 1.4, 0.6, and 0.3 mg kg-1, respectively. The results revealed that the concentration of heavy metals and MS in the pine needles followed the order Fe > Zn > Pb > Cu > Ni > Co. Also, the heavy metal concentration in the pine needles with different treatments had the following trend: WU > WW. It was shown that there was a significant correlation (p < 0.01) between the heavy metal concentrations and the leaf MS values of the pine needles and the concentration of heavy metals in atmospheric dust. Besides, similar trends were detected for the spatial variability of heavy metals and the pine needles' MS. In general, it could be concluded that the biomagnetic approach could serve as a comparatively fast and low-cost method to detect highly polluted urban areas with selected heavy metals, particularly the areas which are under the influence of anthropogenic and other traffic-related sources.
