“…Nickel, in combination with other elements, can be found naturally in the earth's crust, in all soils, and can also be emitted by volcanoes. It can be found in meteorites and seafloor nodules, which are mineral lumps on the ocean floor [45]. Mining and enterprises that transform scrap or fresh nickel into alloy discharge nickel into the atmosphere, and this is one of the major ways nickel is released into the environment.…”

The environment comprises of biotic and abiotic components interacting as a system. The environment also contains organic and inorganic minerals in optimal concentration required by living organisms for growth, development, and metabolic activities. Due to anthropogenic activities and some natural occurrences, the availability of these elements has drastically increased in the ecosystem beyond the required threshold and permissible limits causing pollution. Heavy metal (HM) is one of the naturally occurring elements that threaten plant, animal, and human health. These HMs have been defined as elements with more than 5gcm-3 relative density that are not readily biodegradable but can be transformed from one state to another and are usually associated with toxicity or ecotoxicity. However, some heavy metals are biologically essential elements required in the body/plant or as constituents of important enzymes although in trace amounts while others are non-essential and are ranked as priority metals due to their high level of toxicity with no biological importance even at low concentrations. The non-degradability property of heavy metals contributes to its persistence and subsequent accumulation in the biota and the food chain which is of public health significance to humans and animals. The soil environment is highly prone to HM contamination due to physiological, biochemical, metabolic, and biogeochemical processes that occur within the environment mostly mediated by microbes. These microbes are inarguably the drivers of ecosystem functioning, although they are significantly the most affected by HM pollution. This review, therefore, describes the ecotoxicological effect of heavy metals with special reference to the soil environment. Other sections discussed are the toxicity and general properties of some selected heavy metal, their role as environmental pollutants and essential elements. In addition, the effect of HM on soil microbes has also been analyzed in two folds: i) reduction in microbial population and diversity and ii) increased diversity and abundance of HM-resistant microbial strains which are significant in bioremediation studies

“…Due to their coordination ability, heavy metal ions are highly toxic, thereby directly or indirectly affecting the environment and human health. The Ni 2+ ion, in particular, is highly hazardous for human and marine life even at low concentrations . The World Health Organization (2000) recommended the maximum permissible limit for Ni 2+ ions in drinking water up to 0.02 mg L –1 .…”

The presence of an abnormal amount of Ni2+ in the human body causes various health issues. Therefore, this work aimed to synthesize the curcumin-based fluorescence-on sensor P [2,6-bis((E)-4-chlorobenzylidene)-cyclohexan-1-one] that was capable of selectively responding to Ni2+ ions in aqueous solution. The structure of P was confirmed by 1H NMR and Fourier transform infrared (FTIR) spectroscopy. The Ni2+ ion sensing was based on the fluorescence enhancement of the fluorophore ( P ) in neutral aqueous medium. The response of the P -based sensor was highly selective toward Ni2+ ions, whereas the possible interferences from other metal cations were negligible. P had a fast response; it was selective and had a sensitive detection limit (LOD = 2 × 10–10 M) toward Ni2+ ions in neutral medium with a high association constant (K) value of 3.6 × 105 M–2 for the complex formation between the P and Ni2+ ions. Job’s plot and DFT calculations proved that the binding stoichiometry of P for Ni2+ was 2:1. P was recovered using EDTA as a chelating agent after being employed as a fluorescent sensor. These characteristics ensured the potential use of P as a new class of chemosensor for environmental applications.

The current investigation deals with the treatment of water pollution that is caused by the leaching of nickel ions from the metallurgical industry and new-energy batteries. Therefore, an eco-friendly treatment of nickel through the use of a composite of cotton stalk biochar with nanozerovalent copper has been presented in this investigation signifying the impact of zerovalent copper in enhancing the adsorption capacity of biochar for nickel adsorption. Thermogravimetric analysis data showed the adsorbent to be significantly stable in the higher thermal range, whereas transmission electron microscopy analysis confirmed the particles to be 27 nm and also showed the cubic geometry of the particles. A much closer scanning electron microscopy analysis shows the morphology of particles to be cubic in shape. Batch adsorption indicated a positive influence of pH increase on adsorption due to the electrostatic attraction between positive nickel ions and post point of zero charge (pHPZC) negative surface of copper biochar composite (pH > 5.5). A high adsorption rate was observed in the first 60 min, whereas adsorption increased with the increase in temperature from 303 to 318 K. Kinetic modeling confirmed the pseudo-first-order to fit best to the data. The apparent activation energy (11.96 kJ mol–1) is indicative of the chemical nature of the process. The adsorption data fitted well to the Langmuir adsorption model. The negative values of apparent ΔG° and the positive values of apparent ΔH° indicate the spontaneity and endothermicity of the process, respectively, whereas the positive values of apparent ΔS° point toward increased randomness during the process. Postadsorption XPS suggests the adsorption of nickel on the surface of biochar composites in the form of Ni(OH)2 and NiO(OH).
