This study is conducted in the Kordofan region, central-southern Sudan. The study area is bounded by longitudes 28° 00' and 31° 00' E, and latitudes 11° 30' and 15°00' N and covers an area of about 125835 km2. The Kordofan region is located at the southern end of the present-day Sahara. Late Pleistocene-Holocene deposits in Kordofan, recorded sedim...

Elevated nutrient inputs have led to increased eutrophication in coastal marine ecosystems worldwide. An understanding of the relative contribution of different nutrient sources is imperative for effective water quality management. Stable isotope values of nitrate (δ15NNO3-, δ18ONO3-) can complement conventional water quality monitoring programs to...

In the present study, some mud volcanoes in Pingtung and Kaohsiung areas were selected. The selected mud volcanoes are located above the mud diaper system in southern Taiwan. Three different sampling techniques were used to collect samples in and around the said mud volcanoes. The results show that river water samples from different places fall on ...

The Neoproterozoic sulfur isotope (δ34S) record is characterized by anomalously high δ34Spyrite values. Many δ34Spyrite values are higher than the contemporaneous δ34Ssulfate (i.e., δ34Spyrite > δ34Ssulfate), showing reversed fractionation. This phenomenon has been reported from the Neoproterozoic post-glacial strata globally and is called “Neoprot...
The GEOTRACES Intermediate Data Product 2017 (IDP2017) is the second publicly available data product of the international GEOTRACES programme, and contains data measured and quality controlled before the end of 2016. The IDP2017 includes data from the Atlantic, Pacific, Arctic, Southern and Indian oceans, with about twice the data volume of the pre...

The aim of this work is to understand the role of unsaturated zone on the functioning of karst aquifers. The easy infiltration of water into the system explains the expansion of karstification through the saturated zone. The unsaturated zone is largely involved in the flow on the overall karstic system. For this purpose, we use the environmental tr...

This pilot study investigated tree bark as a potential biomonitor of thorium and radium contamination in the environment, using the former Fernald Feed Materials Production Center (FFMPC) in southwest Ohio as a test case. Tree bark samples collected in the vicinity of the FFMPC have radium and thorium concentrations ~ 8X and ~ 10X background levels...

Key messageThe relationship between sapwood area and foliar δ13C values varies among 236 Salix genotypes, indicating different water use patterns across these genotypes.AbstractThe relationship between leaf δ13C and plant size (represented by e.g. total leaf area) has been used to analyze different water use patterns of plants. However, the total l...
Published in Waste management (New York, N.Y.)
Where the unique natural water resource is groundwater, the attention and the susceptibility of local communities and authorities to groundwater quality degradation risks can be so high to determine relevant problems to waste management, especially for landfills in operation or to be realised. A multi-methodological approach was suggested with the ...
