Magnetic nanomaterials as an effective absorbent material for removal of fluoride concentration in water: a review.

The rapid increases in industrialization and populations are significant sources of water contamination. The speed with which contamination of groundwater and surface water occurs is becoming a serious problem and poses a significant obstacle for water stakeholders. Heavy metals, organic, and inorganic contaminants in the form of suspended and dissolved materials are just a few of the contaminants that can be found in drinking water.

Estimation of nitrous oxide emissions from rice paddy fields using the DNDC model: a case study of South Korea.

The Denitrification-Decomposition (DNDC)-Rice is a mechanistic model which is widely used for the simulation and estimation of greenhouse gas emissions [nitrous oxide (NO)] from soils under rice cultivation. NO emissions from paddy fields in South Korea are of high importance for their cumulative effect on climate. The objective of this study was to estimate the NO emissions and biogeochemical factors involved in NO emissions such as ammonium (NH) and nitrate (NO) using the DNDC model in the rice-growing regions of South Korea.

A simplified sampling procedure for the estimation of methane emission in rice fields.

Manual closed chamber methods are widely used for CH measurement from rice paddies. Despite diurnal and seasonal variations in CH emissions, fixed sampling times, usually during the day, are used. Here, we monitored CH emission from rice paddies for one complete rice-growing season.
