Seen in the light of increasing anthropogenic impacts on the environment and a growing demand for potable water, pollution of groundwater is a very important issue, especially in large city areas. The present research includes analyses of the chemical composition at 109 measuring points in the Wrocław area, and of the spatial distribution of ground...

Nitrogen (N) is normally applied twice during sugarcane cultivation on Negros Island in the Philippines. As the first application is carried out during the early growth stage, there is a high possibility that N is not absorbed sufficiently by the sugarcane and a large amount of N may be leached with percolating water. To investigate this leaching, ...

Agriculture is a significant contributor to nitrate pollution of groundwater which in many cases serves as a source of drinking water. Therefore, targeted reduction of nitrogen leaching losses is fully justified to address this issue. The aim of the study was to define the areas of utilized agricultural land (UAL) in Slovakia, where a nitrogen surp...

During the rapid urbanisation of Beijing in the past two decades, the original natural underlying surface has been changed, and the groundwater recharge and discharge processes had undergone great changes. Therefore, whether these natural and human factors affect the evolution of groundwater chemical composition, and how these influences evolve, ne...

Groundwater quality due to geogenic factors, aggravated by anthropogenic activities, is a significant threat to human wellbeing and agricultural practices. This study aimed at mapping the spatial distribution of low and high groundwater-contaminated regions in the Sheikhpura district of Bihar for safe drinking and irrigation water availability. To ...

It is essential to increase food production to meet the projected population increase while reducing environmental loads. Biological nitrification inhibition (BNI)-enabled wheat genetic stocks are under development through chromosome engineering by transferring chromosomal regions carrying the BNI trait from a wild relative (Leymus racemosus (Lam.)...

Kemijsko stanje podzemne vode odprtih in dobro prepustnih vodonosnikov je odvisno od naravnih in antropogenih dejavnikov. Antropogen vir povišane mineralizacije so zelo pogosto območja odlagališč odpadkov, kjer se raztopljeni ioni in minerali po prostoru razširjajo v odvisnosti od smeri toka podzemne vode. Komunalno odlagališče Črneče se nahaja v s...

Groundwater vulnerability and hazard maps are often combined to produce GIS-based cartographic representations of the risk of groundwater pollution in studied aquifers. Results remain however often quite subjective for two main reasons. First, identification, in the investigated catchment, of anthropogenic activities often requires a combination of...

One major environmental challenge facing humankind is the constantly increasing pollution of water and soil resources on a global scale. The substances that cause such pollution arise primarily from human-made wastes, including agricultural and industrial wastes, household garbage, oil spills, and other toxic materials. The spatiotemporal distribut...
