Exploring the origins and cleanup of mercury contamination: a comprehensive review.

Mercury is a global pollutant that poses significant risks to human health and the environment. Natural sources of mercury include volcanic eruptions, while anthropogenic sources include industrial processes, artisanal and small-scale gold mining, and fossil fuel combustion. Contamination can arise through various pathways, such as atmospheric deposition, water and soil contamination, bioaccumulation, and biomagnification in food chains.

Mitigation of nitrous oxide emission through fertigation and 'N' inhibitors - A sustainable climatic crop cultivation in tomato.

The impact of nitrous oxide (NO) released from the fertilized agro-ecosystems are of increasing concern. Governing fertilizer requirements and utilizing nitrification inhibitors (NI) are effective methodologies to increase nitrogen retention and reduce NO emissions from soil. Therefore, the effect of potassium thiosulfate (KTS) and neem-coated urea (NCU) on NO efflux under irrigated tomato cultivation was assessed.

Application of advanced materials in sonophotocatalytic processes for the remediation of environmental pollutants.

Significant advances in various industrial processes have resulted in the discharge of toxic pollutants into the environment. Consequently, it is essential to develop efficient wastewater treatment processes to reduce water contamination and increase recycling/reuse. Photocatalytic degradation is considered as an efficient method for the degradation of toxic pollutants in industrial wastewater.

Mitigation of methane gas emissions in flooded paddy soil through the utilization of methanotrophs.

The utilization of methanotrophs for reducing the global warming potential in a flooded paddy system is the progressive investigation in the recent. The field investigation was conducted in Tamil Nadu Rice Research Institute, Aduthurai. This study showed the effect of isolated methanotroph strain (MR) on the reduction of methane emission and improvement in growth parameters and yield of paddy.

Ultrasound promoted transition metal doped polyaniline nanofibers: Enhanced electrode material for electrochemical energy storage applications.

Here in, we report a simple and facile method to synthesis morphology oriented transition metal (Nickel) doped polyaniline (Ni/PANI) by chemical oxidative polymerization with the assistance of ultrasonic irradiation. Physicochemical property of the materials examined through XRD and FT-IR. The morphological feature exposed that the sonochemical assisted Ni doped PANI is differing from the conventional method and it reveals a notable electrochemical property as in the form of specific capacitance (370 F g at 0.
