The study was conducted to quantify Pb, Ni, Cr, Cd, Cu, and Fe in drinking water (surface and subsurface water) from Nawanshahr Town, Abbottabad, Pakistan, and to evaluate the associated threat to the health of the inhabitants. An atomic absorption spectrometer (Perkin Elmer, AAS-700) was utilized...

Contamination of the food chain by toxic metals is one of the main concerns for human health. Milk is part of a balanced diet; essential for proper growth, but can also contains hazardous chemicals and contaminants including heavy metals which can be a risk for health. The aim of this study is to...

A green synthesis using a simple precipitation method produced zinc oxide (ZnO), leaf extractions of zinc oxide as Aerva lanata (Al-ZnO) and Millettia pinnata (Mp-ZnO), copper-doped Al-CZnO and Mp-CZnO nanoparticles (NAPs). They were characterized for their functional group, structural...

Tamarindus indica shell biochar is employed as an alternate adsorbent precursor for the removal of heavy metal ions from aqueous solutions. It investigated the Tamarindus indica shell biochar's capacity to absorb chromium (Cr), copper (Cu), and Lead (Pb). This study showed the extensive explored how...

The increasing industrialization and urbanization in recent times has led to a significant increase in heavy metal pollution in soil and sediment. The present study aims to evaluate the heavy metal contamination (HmC) in surface sediments collected from the Kosasthalaiyar River located between...

Transportation driven by fossil fuels increases air pollution induced by urbanisation. Heavy metals such as Cadmium (Cd), Chromium (Cr), Copper (Cu), Iron (Fe), Lead (Pb), and Zinc (Zn) are life-threatening elements and their concentration is increasing alarmingly in soil in various countries. Air...

In order to explore an effective assessment method for the treatment effect of heavy metal pollution in the sediment of Taihu Lake in China, based on the research background analysis and literature review, this paper reconstructs the spatial niche suitability model and applies it to the effect...

Several chemical coagulants previously utilize for wastewater treatment with significant performance in removing heavy metals and other parameters. However, their cost effective and the residual of toxic chemical precipitates that pose problems to human health and the environment. Therefore, using...

In the current study, three different photo-assisted sources were used to evaluate the photo-Fenton oxidation process for the pollutant degradation of mature landfill leachate. Solar, UV, and LED visible light photo sources were adopted in this Fenton process. Fenton dosages (FeSO4 : H2O2) 1:30, 1.5...

TiO2 is the most effective photocatalyst but it has low adsorption in the visible region. Many efforts have been done to improve its photocatalytic activity in the solar region. In this study we use Mo-oxy species supported on titania surface since it is well known that titania surface can dispersed...

The constant development of technological processes aggravates the problem of pollution, due to a significant change in the composition of effluents, which makes necessary new (and/or improved) treatment methods and catalytic materials. In this sense, the use of natural clays in the synthesis of low...

In Gilgit-Baltistan, urbanization, transportation, unplanned small-scale industry, kitchen waste, inorganic fertilizers, pesticides, insecticides, and weedicides contribute to agricultural field contamination, creating severe health risks. This study aims to determine the health risks caused by...
