Global trends and environmental issues in nickel mining: sulfides versus laterites

TL;DR: In this article, pyrazole-based pyridine ligands, 2-(3-butyl-1H-pyrazol-5-yl)-pyridine (1), 2-[3-(tert- butyl)-1H-, pyrazol 5-yl]-pyridine (2), and 2-( 3-octyl- 1H-pyride-5yl)-polycyclic pyride (3-Pyride), were synthesized and fully characterised using conventional means.

TL;DR: In this paper, the authors identify and explore the common environmental effects of mining in Western Australia (WA) and examine site-specific factors with reference to metals, mine life cycle, cumulative impacts and temporal disturbance.

TL;DR: In this article, a selective reduction of saprolite and limonite was carried out to reveal the effect of lateritic nickel ore basicity (MgO/SiO2 ratio) on phase transformation and microstructure of reduced nickel ore.

TL;DR: In this article, the authors analyzed research trends in the field of sustainable management of metals on a global level between 1993 and 2017 and revealed the growing interest in this research field, particularly over the last five year-period during which 63% of all articles were published.

Abstract: The Working Group I contribution to the IPCC Fourth Assessment Report describes progress in understanding of the human and natural drivers of climate change1, observed climate change, climate processes and attribution, and estimates of projected future climate change. It builds upon past IPCC assessments and incorporates new findings from the past six years of research. Scientific progress since the TAR is based upon large amounts of new and more comprehensive data, more sophisticated analyses of data, improvements in understanding of processes and their simulation in models, and more extensive exploration of uncertainty ranges.

TL;DR: New metabolic and mechanistic data are used to suggest a basis for the failure of "classical" risk assessment methods to provide accurate predictions for humans in this instance.

TL;DR: A tentative monetary value is put on Hg polluted food sources in the Arctic, where local, significant pollution sources are limited, and this to costs for strategies avoiding Hg pollution and to remediation costs of contaminated sites in Sweden and Japan.
