Clean and safe water is vital for our lives public health. In recent decades, population growth, agriculture, industries, climate change have worsened freshwater resource depletion clean pollution. Several studies focused on pollutions risk simulation prediction in the presence of pollution hotspots. However, increase complexity big data caused by uncertain quality parameters led to a new effic...

This review considered groundwater resources, its characteristics, qualities, pollutions and available treatments. Groundwater refers to all the water occupying the voids, pores and fissures within geological formations, which originated from atmospheric precipitation either directly by rainfall infiltration or indirectly from rivers, lakes or canals. The chemical, physical and bacterial charac...

We present the abundance ratios [X/H] of a large set of chemical species with T C from 75 to 1600 K in an almost complete set of 105 planet-host stars and in a volume-limited comparison sample of 88 stars without any known planets. The large range of different T C covered by all the analysed elements allows us to investigate possible anomalous trends of [X/H] vs. T C in targets with planets wit...

Anaerobic wastewater treatment differs from conventional aerobic treatment. The absence of oxygen leads to controlled conversion of complex organic pollutions, mainly to carbon dioxide and methane. Anaerobic treatment has favourable effects like removal of higher organic loading, low sludge production, high pathogen removal, biogas gas production and low energy consumption. Psychrophilic anaero...
