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.

Biomining for halotolerant PGPR and endophytes for promotion of salt tolerance in L.

Halophytic plants can tolerate a high level of salinity through several morphological and physiological adaptations along with the presence of salt tolerant rhizo-microbiome. These microbes release phytohormones which aid in alleviating salinity stress and improve nutrient availability. The isolation and identification of such halophilic PGPRs can be useful in developing bio-inoculants for improving the salt tolerance and productivity of non-halophytic plants under saline conditions.

Kinetic and isotherm insights of Diclofenac removal by sludge derived hydrochar.

Recently, hydrothermal carbonization emerges as the most viable option for the management of solid waste with high moisture content. Sludge derived hydrochar is used as an adsorbent for emerging contaminants or micro-pollutants in the domain of sustainability. Current study demonstrates the KOH activation of hydrochar produced from paper board mill sludge and evaluates its removal potential of a Non-steroidal anti-inflammatory drug, Diclofenac from aqueous solution.

Phytolith-Occluded Carbon Sequestration Potential of Oil Palm Plantation in Tamil Nadu.

Oil palm () has proven to be a phytolith-occluded carbon (PhytOC)-rich species that plays a vital role in acting as a carbon sink for reducing atmospheric carbon dioxide (CO) concentration. The present research estimated the silicon, phytolith, and PhytOC contents in four (OP4), eight (OP8), and fifteen (OP15)-year-old oil palm plantations. Qualitative analysis using a scanning electron microscope (SEM) revealed the presence of abundant globular echinate phytoliths with varied diameter (8.

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.

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.
