“…The intensity of the hydrolysis of sulfate esters is negatively correlated with the contents of lead and copper in the soil, and to a smaller extent with the contents of zinc, nickel, and cadmium [35]. Nevertheless, an increase in contamination of the soil environment with zinc and cadmium may adversely affect arylsulfatase activity.…”

Contamination of soils by heavy metals is a severe problem because of disturbances caused in the functioning of the soil and the whole ecosystem. Therefore, the aim of our research was to determine the influence of contamination of soil by zinc, copper, nickel, cadmium, and lead on the activity of arylsulfatase. A novel element of the study is a comparison of the response of arylsulfatase to five heavy metals in three soils with two pH ranges: 7.0 and 5.5. The studies were carried out under laboratory conditions. The soils (loamy sand, sandy loam, sandy clay loam), with pH 7.0 and 5.5 and contaminated with zinc, copper, nickel, cadmium, and lead were incubated for 30, 60, and 120 days. After each period, the activity of arylsulfatase was determined. Base on the activity of arylsulfatase, a resistance index of arylsulfatase (RS) to contamination with heavy metals was calculated. The highest activity of arylsulfatase was found in sandy clay loam, while the lowest was found in loamy sand. A significant correlation between the resistance of the enzyme and the level of contamination of the soil with heavy metals was proved. Arylsulfatase was most sensitive to the effects of zinc, copper, and nickel, while cadmium exerted a somewhat weaker influence and lead the least. The enzyme exhibited a higher resistance to the influence of heavy metals in neutral soils than in acidic soils. The toxic effect of heavy metals can be ordered as follows: zinc > copper > nickel > lead > cadmium.

“…Firstly, improvements in soil physicochemical conditions, especially OM, may have inactivated the impacts of metals. According to Gülser and Erdogan (2008), OM-metal complexes occur in OM and soil solutions and would prevent the metals from interacting directly with the active sites of enzymes. Kizilkaya and Bayrakli (2005) found that sludge application increased available metal (Cu, Ni, Pb and Zn) contents in the soils.…”

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.

“…Even though metals like Zn, Cu and Mn act as cofactor in several enzyme activities and that Fe is directly involved with haemoglobin formation in the blood tissues, their presence in excessive concentration might be toxic to the fish (Zyadah and Abdel-Bakey 2000;Ikem et al 2003). Pb is also a toxic element and has no known biological function and shows its negative health effect on aquatic biota and humans (Shahtaheri et al 2007;Gulser and Erdogan 2008). Chromium is considered as essential trace elements.…”

The aim of this study was to investigate the potential impact of effluent released during metals extraction from polymetallic sea nodules at the Pilot Plant at National Metallurgical Laboratory, India, by analysing different metal (Mn, Cu, Zn, Fe, Pb and Cr) concentrations in six tissues (skin, muscles, gills, liver, kidney and brain) of the fish Labeo rohita. Of the six analysed tissues of seanodule-effluent-exposed fish, liver accumulated highest concentration of most of the metals (2.91-287.36 mg kg -1 ) while muscles (2.1-81.14 mg kg -1 ) lowest. While the concentration of Fe was maximum (60.41-218.7 mg kg -1 ) in all the tissue systems (except muscles and liver), Pb was minimum (0.8-2.91 mg kg -1 ). Accumulation of most of the metals in all the tissues was above the safe limits as recommended by Food and Agricultural Organisation that indicate metal's potential hazardous impact on the fish. High bioaccumulation factors for these metals in the different tissues revealed that metals were extensively bio accumulated and bio concentrated. The time-dependent variation in metal pollution index illustrated increase in gross metal load (p \ 0.05) in different tissue components with increase in exposure period. In conclusion, the sea nodule effluent was found to cause adverse health impact on the fish which in turn might also affect the human health when consumed.
