“…Many authors who in these tests have applied organic amendments or used soils with high organic matter contents have not detected toxic effects even at high metal concentrations. [12,34] However, there exist totally contradictory results, with significant inhibitions of heterotrophic respiration due to the presence of one of the studied metals, despite the addition of organic matter. [35] There are only two groups of factors that can contribute to this variability among the results reported in different previous studies: (1) factors which modify the toxicity of the metals and (2) differences in the sensitivity of soil microorganisms or in www.advancedsciencenews.com www.clean-journal.com microbial processes.…”

“…that are able to absorb, complex, or (co)precipitate trace elements. The application of organic by‐products has been also demonstrated to be useful for contaminant immobilization, with some advantages over other methods such as low cost, its in‐situ applicability and its low environmental impact . Organic amendments are considered especially effective in Cr stabilization, while in the case of other trace elements (As, Cu, Zn, and Pb) they may have both positive and negative effects …”

Ecotoxicity of three potentially toxic metals (PTM) (Cu, Zn, and Cr) in a slightly acidic sandy soil is tested using the soil respiration test (OECD‐217) in order to determine EC50 values for the carbon transformation activity of microorganisms. Addition of an organic amendment of Populus leaves is also crossed with metal spiking in order to investigate possible interaction with metal toxicity. Soil respiration is measured at day 1 and 28 after the soil spiking with the PTM to assess short‐term effects on soil microbial activity. Of the three metals tested, Cu shows the highest toxicity at the longest exposure times (day 28) and Zn shows a strong inhibitory effect in the short‐term (day 1), even though later toxicity diminish significantly. Cr is the least toxic studied PTM. Organic amendment outweighs any adverse effects of these metals, increasing soil respiration, even in the treatments with high doses of metals.

The objective of this study was to explore the potential use of pulp (by-product) from coffee processing and Na-bentonite (commercial product) for minimizing the environmental risk of Zn, Pb and Cd in soil collected from a former mine and zinc-lead smelter. The effects of soil amendments on the physicochemical properties of soil, the structural and functional diversity of the soil microbiome as well as soil enzymes were investigated. Moreover, biomass of Festuca arundinacea Schreb. (cultivar Asterix) and the uptake of trace elements in plant tissues were studied. The outdoor pot set contained the following soils: control soil (initial), untreated soil (without additives) with grass cultivation and soils treated (with additives) with and without plant development. All of the selected parameters were measured at the beginning of the experiment (t0), after 2 months of chemical stabilization (t2) and at the end of the aided phytostabilization process (t14). The obtained results indicated that both amendments efficiently immobilized the bioavailable fractions of Zn (87–91%) and Cd (70–83%) at t14; however, they were characterized by a lower ability to bind Pb (33–50%). Pulp and Na-bentonite drastically increased the activity of dehydrogenase (70- and 12-fold, respectively) at t14, while the activities of urease, acid and alkaline phosphatases differed significantly depending on the type of material that was added into the soil. Generally, the activities of these enzymes increased; however, the increase was greater for pulp (3.5-6-fold) than for the Na-bentonite treatment (1.3–2.2-fold) as compared to the control. Soil additives significantly influenced the composition and dynamics of the soil microbial biomass over the experiment. At the end, the contribution of microbial groups could be ordered as follows: gram negative bacteria, fungi, gram positive bacteria, actinomycetes regardless of the type of soil enrichment. Conversely, the shift in the functional diversity of the microorganisms in the treated soils mainly resulted from plant cultivation. Meanwhile, the highest biomass of plants at t14 was collected from the soil with Na-bentonite (6.7 g dw-1), while it was much lower in a case of pulp treatment (1.43–1.57 g dw-1). Moreover, the measurements of the heavy metal concentrations in the plant roots and shoots clearly indicated that the plants mainly accumulated metals in the roots but that the accumulation of individual metals depended on the soil additives. The efficiency of the accumulation of Pb, Cd and Zn by the roots was determined to be 124, 100 and 26% higher in the soil that was enriched with Na-bentonite in comparison with the soil that was amended with pulp, respectively. The values of the soil indices (soil fertility, soil quality and soil alteration) confirmed the better improvement of soil functioning after its enrichment with the pulp than in the presence of Na-bentonite.

“…Pollution can directly poison the microorganism, hinder the normal growth and development, cause the environment to change, cause the microorganism to lose the living environment, affect the structure, function and dynamics of each level of ecosystem, then cause the ecosystem to degenerate (BOLDT & JACOBSEN, 2010;WASILKOWSKI et al, 2015). This results in a reduction at the genetic, population and ecosystem levels.…”

Biodiversity plays a key role in human welfare by providing agricultural, economic, and health benefits. However, following the industrial revolution, the rapid expansion of the human population and subsequent economic activities have caused a dramatic loss in global biodiversity, resulting in significant disturbances to ecosystems and our own living conditions. Accordingly, the conservation of biodiversity has become one of the most important challenges for humanity. The vast numbers of plants, animals, and microorganisms, the enormous genetic diversity of these species and the different ecosystems to which these organisms belong are all part of a biologically diverse planet. A substantial proportion of the world’s biodiversity has been destroyed, this loss is a catastrophe for all living species, including humans. Fortunately, we are working to remedy the destruction of our ecosystems. Herein, we summarized the discovery and development of biodiversity as a field of study and discuss the importance of the genetic and metabolite diversity. We proposed potential solutions to the loss of biodiversity with the aim of facilitating further exploration and identification of biodiversity, contributing for human welfare through the conservation of human habitats.
