  • Interaction between nickel and cobalt toxicity in Enchytraeus crypticus is due to competitive uptake

    Uptake and toxicity of Ni‐Co mixtures in Enchytraeus crypticus were determined after 4, 7, 10 and 14 d exposure. Generally, body concentrations of Ni and Co increased with increasing exposure concentrations. Ni body concentration was significantly reduced in the presence of Co, while Ni only marginally affected Co uptake. When expressed as free ion activities, individual toxicity of Ni and Co ...

  • Applying biotic ligand models and Bayesian techniques: Ecological risk assessment of copper and nickel in Tokyo rivers

    Biotic ligand models (BLMs) have been broadly accepted and used in ecological risk assessment of heavy metals for toxicity normalization with respect to water chemistry. However, the importance of assessing bioavailability by using BLMs has not been widely recognized among Japanese stakeholders. Failing to consider bioavailability may result in less effective risk management than would be ...

  • Hydrogen species in CeNi1OY and CeAl0.5Ni1OY mixed oxides' catalytic hydrogen reservoirs

    The interaction of hydrogen with cerium nickel and aluminium-based mixed oxides (CeNi1OY and CeAl0.5Ni1OY) has been studied by catalytic hydrogenation and Inelastic Neutron Scattering (INS). The mixed oxides are large catalytic hydrogen reservoirs called oxyhydrides and the presence of Al allows increasing hydrogen storage and giving the system better stability, in particular, with increasing ...

  • Heavy metal speciation and mobility assessment of arid soils in the vicinity of Al Ain landfill, United Arab Emirates

    Sixty-four surface soil samples taken in the vicinity of Al Ain landfill were analysed for cadmium, chromium, copper, nickel, lead and zinc by inductively coupled plasma spectroscopy. Extraction techniques were used to establish the association of the total concentrations of the six metals in the soil samples with their contents in the exchangeable, carbonate, iron/manganese oxides, and residual ...

  • Heavy metal levels in tap water in Batina Region, Oman

    Most household in Batina depend on private wells for their fresh water supplies. The quality of such water is not regulated or tested by authorities and, therefore, consumers' health might be at risk if water is contaminated. We assessed the contribution of some heavy metals to water pollution. Water samples from 364 houses were collected and analysed for levels of lead, chromium, nickel and ...

  • Accumulation of heavy metals in the bottom sediments of the Irkutsk Reservoir

    The chemical composition of the bottom sediment, and more particularly the heavy metals content, reflects human developments and impacts on the catchment and reservoir's natural environment. The bottom sediments of the reservoir retained by the Irkutsk Dam have been analysed. The reservoir is mainly supplied by water from Lake Baikal. The following amounts of heavy metals have been found in the ...

  • Heavy Metals Analysis

    Correct measurement results are a prerequisite for compliance with limit values, which are always specified as total metals. Heavy metals such as copper, nickel, zinc, etc. can be quickly and reliably determined in aqueous samples with the help of the LANGE cuvette tests. Matrix factors (e.g. interference ions, colour, turbidities, etc.) may have a negative impact on themeasurement and cause ...


  • Environmental qualitative assessment of rivers sediments

    In this study, the concentrations of heavy metals (Ca, Zn, Cu, Fe, Mn, Ni) in thesediment of Shavoor River in Khuzestan Province in Iran has been investigated. After the library studies and field studies, six samples of water and sediment were taken from the river in order to evaluate heavy metal pollution in sediments. To determine the geochemical phases of metals in sediment samples the 5-step ...

  • Chemiluminescent examination of abiotic oxidative stress of watercress

    Watercress (Nasturtium officinale) is an aquatic plant that readily bioaccumulates heavy metals that may be found in contaminated aquatic systems. Toxic effects of contaminants on the physiological processes cause changes in oxidase enzymatic activity in watercress, which can be measured using a luminometer. The luminometer uses the reaction produced when peroxidases break down hydrogen ...

  • Unexpected toxicity to aquatic organisms of some aqueous bisphenol A samples treated by advanced oxidation processes

    In this study, photocatalytic and catalytic wet-air oxidation (CWAO) processes were used to examine removal efficiency of bisphenol A from aqueous samples over several titanate nanotube-based catalysts. Unexpected toxicity of bisphenol A (BPA) samples treated by means of the CWAO process to some tested species was determined. In addition, the CWAO effluent was recycled five- or 10-fold in order ...

  • The potential for reusing treated municipal wastewater for irrigation in the Hashemite Kingdom of Jordan

    This paper elaborates on the chemical composition of wastewater at selected Wastewater Treatment Plants (WWTPs) in Jordan. These plants have immense potential of providing reused treated water for irrigation. Samples from treated effluents analysed to study the efficiency of the impact of treated water on irrigation. The results revealed the effluents from WWTPs could be used for irrigation with ...

  • Finding the ‘boundary mediators’: network analysis of the joint R&D project between Toyota and Panasonic

    In recent years, a large and growing number of companies have attempted to develop core technologies for their products by conducting joint research with a company in a different industry. However, the mechanisms by which technologies are acquired and assimilated through cross-industry research remains unclear. In response to this ambiguity, we developed a theoretical framework for this ...

  • Removal of Ni2+ from aqueous solution by rice bran

    Rice bran, an agricultural by-product, was used for the sorptive removal of Ni2+ from aqueous solutions. Batch adsorption experiments were performed as a function of initial concentrations, contact time, pH and temperature. The experimental data were analysed by Langmuir, Freundlich and Redlich-Peterson isotherms. The equilibrium sorption capacity of Ni2+ was determined from the Langmuir equation ...

  • Solid Waste Management: A Case Study of National Refinery Limited

    Investigations have been carried out to assess and characterize the waste being generated in one of the largest petrochemical refinery of Pakistan. It was found that the refinery complex generates about 2000 metric tons of solid waste and about 0.55 million gallons of waste water per day. Besides these gaseous pollutants like H2S, CO, CO2 NO2, and particulate matter are also emitted in the ...

  • Metallurgy - The biggest copper smelter in Finland

    The Boliden smelter in Harjavalta, western Finland, is a traditional plant of handling copper and nickel concentrates and was, in fact, the location where the flash smelting method was developed in 1949. Today this method is used all over the world. The original copper smelter was established in eastern Finland in 1936 by Outokumpu Oy but the Second World War prompted its relocation in the ...
