“…Microorganisms require certain metals at low concentrations as essential micronutrients for vital cofactors for metalloproteinase and certain enzymes, but heavy metals become toxic to most microorganisms at high concentrations (Nies 1999). However, urease activity showed a linear decrease with increasing Cd and Pb concentration in the present study, and this result is consistent with other research (Jin et al 2014). Soil urease, as an exocellular enzyme, mainly originates from soil microbial metabolites and root exudates, and heavy metal would inhibit microorganism or root growth and then reduce the urease source.…”

Microorganism or chelate-assisted phytoextraction is an effective remediation tool for heavy metal polluted soil, but investigations into its impact on soil microbial activity are rarely reported. Consequently, cadmium (Cd)-and lead (Pb)-resistant fungi and citric acid (CA) were introduced to enhance phytoextraction by Solanum nigrum L. under varied Cd and Pb pollution levels in a greenhouse pot experiment. We then determined accumulation of Cd and Pb in S. nigrum and the soil enzyme activities of dehydrogenase, phosphatase, urease, catalase, sucrase, and amylase. Detrended canonical correspondence analysis (DCCA) was applied to assess the interactions between remediation strategies and soil enzyme activities. Results indicated that the addition of fungi, CA, or their combination enhanced the root biomass of S. nigrum, especially at the high-pollution level. The combined treatment of CA and fungi enhanced accumulation of Cd about 22-47 % and of Pb about 13-105 % in S. nigrum compared with the phytoextraction alone. However, S. nigrum was not shown to be a hyperaccumulator for Pb. Most enzyme activities were enhanced after remediation. The DCCA ordination graph showed increasing enzyme activity improvement by remediation in the order of phosphatase, amylase, catalase, dehydrogenase, and urease. Responses of soil enzyme activities were similar for both the addition of fungi and that of CA. In summary, results suggest that fungi and CA-assisted phytoextraction is a promising approach to restoring heavy metal polluted soil.

“…Regression analysis were carried out using the statistical software package SPSS (Statistical Program for the Social Sciences, release 20.0). CANOCO software package for Windows 4.5 was used to obtain the canonical correspondence analysis (CCA) to find out the contribution of physicochemical properties of soil samples on HM accumulation in soil samples (Jin et al, 2014).…”

“…Among excessive pollution factors, Cd is the dominant pollution factor, and further studies are needed to investigate the potential impact of Cd pollution. 3.4 CCA analysis of soil physicochemical properties and HM contents CCA is a powerful tool to find out the correlation between elemental concentration and environmental variables (Shahriary et al, 2012;Jin et al, 2014;Srinivasan et al, 2015). CCA analysis result shows that the eigenvalues of the first three ordination axes are 0.523, 0.158, and 0.125, and the correlation coefficients with HMs content axis are 0.857, 0.923 and 0.895, respectively (data not shown).…”

The intensive management practices in greenhouse production may alter the soil physicochemical properties and contribute to the accumulation of heavy metals (HMs). To determine the HM concentrations in vegetable soil in relation to soil physicochemical properties and cultivation age, we conducted a soil survey for typical greenhouse soils in Shouguang, China. The results indicated that Cd is a major HM pollutant in the tested soils, as the only HM element exceeding the allowed limit for vegetable soil. The surveyed data was analyzed with regression analysis, correlation analysis and canonical correspondence analysis (CCA). A positive correlation is observed between HM pollution level and cultivation age. CCA results suggest that the HM pollution level and distribution in soil are significantly affected by soil physicochemical properties, which was a function of years of cultivation as revealed by regression analysis. In summary, cultivation age is an important factor to affect soil physicochemical properties (organic matter and inorganic nutrients) as well as HM contamination.

“…Samples were then placed in a refrigerator at 4°C (Gianfreda et al 2005;Lai et al 1999;Li et al 2015;Perez-de-Mora et al 2005;Jin et al 2014;Qu et al 2011;Romero et al 2005;Moreno et al 2009;Koo et al 2012) to preserve biological properties (Claassens et al 2008;Maboeta et al 2006), and chemical analysis was carried out within 3 weeks. Immediately prior to analysis, samples were removed from the refrigerator, placed on petri dishes and laid on the table for air-drying.…”

Past mining activities in Swaziland have left a legacy of abandoned mine sites (iron ore, asbestos, diamond and coal mine dumps), all of which have not been reclaimed. These sites were recently (2013) considered by the country's wastewater treatment authorities as suitable places where biosolids can be applied, firstly as a biosolids disposal alternative and, secondly, as a strategy to accelerate mine soil remediation through phytostabilization. In order to understand the effects that this might have on mine soil conditions and microbiota, two (2) plant growth trials were conducted in biosolid-treated iron mine soils and one (1) trial on undisturbed soil, under greenhouse conditions, for twelve (12) weeks. According to the results obtained, the combination of biosolids and plants led to significant improvements (p \ 0.05) in parameters related to soil fertility. Significant increases (p \ 0.05) in alkaline phosphatase, b-glucosidase and urease soil enzyme activities were also observed. Copper and zinc were significantly (p \ 0.05) increased (Cu from 17.00-50.13 mg kg ); however, these sludge-derived metals did not affect enzyme activities. Improvements in soil physicochemical conditions, organic matter-metal complexes, effects of plants on metals and the essentiality of Cu and Zn to soil enzymes were thought to have masked the effects of metals. Increases in soil enzyme activities were considered to be indicative of improvements in the quality, fertility health and self-purification capacity of iron mine soils due to synergistic effects of biosolids and plants.
