Response of dissolved organic carbon in rainwater during extreme rainfall period in megacity
The urbanization impacts on potentially toxic metals
The Impacts of Nitrogen Pollution and Urbanization on the Carbon Dioxide Emission from Sewage-Draining River Networks
Carbon dioxide (CO 2 ) emissions from river water have sparked worldwide concerns due to supersaturate CO 2 levels in the majority of global rivers, while the knowledge on the associations among nitrogen pollution, urbanization, and CO 2 emissions is still limited. In this study, the CO 2 partial pressure ( p CO 2 ), carbon and nitrogen species, and water parameters in sewage-draining river networks were investigated. Extremely high p CO 2 levels…
Suspended Sediments Quality Assessment in a Coastal River
In coastal rivers with various human and damming activities (reservoir), the cycle and biogeochemistry of environmental pollutants in river systems has been modified. A total of 42 suspended particulate matter (SPM) samples were obtained in Jiulongjiang River, southeast China to investigate the concentration, sources, behavior, and risks of nine potentially toxic elements (PTEs) in SPM.

A critical review of the variation in rainwater acidity in 24 Chinese cities during 1982–2018
Rainwater is an essential pathway to remove fine particulate matter and dissolved atmospheric pollutants (e.g., SO2, HNO3, and NH3). Acid rain (pH < 5.6) has been a severe environmental issue in China since the 1970s, adversely impacting ecosystem health. This study focuses on the influence of anthropogenically induced anions (SO42– and NO3–) and alkaline cations (Ca2+ and NH4+) on acid rain in Chinese cities. In this review, cities with high pop…
Vertical Distribution and Controlling Factors Exploration of Sc, V, Co, Ni, Mo and Ba in Six Soil Profiles of The Mun River Basin, Northeast Thailand
Exploring the enrichment and controlling factors of heavy metals in soils is essential because heavy metals can cause severe soil contamination and threaten human health when they are excessively enriched in soils. Soil samples (total 103) from six soil profiles (T1 to T6) in the Mun River Basin, Northeast Thailand, were collected for the analyses of the content of heavy metals, including Sc, V, Co, Ni, Mo, Ba. The average contents of soil heavy …
Spatial Variation and Source of Dissolved Heavy Metals in the Lancangjiang River, Southwest China
Dissolved heavy metals are not only the essential micronutrients, but also the toxic elements for human bodies. To investigate the heavy metal sources and assess the water quality of the Lancangjiang River, dissolved Cr, Ni, Cu, Zn, Mo, and Pb were detected in this study. The results show that dissolved Ni and Mo, Cr and Pb, and Cu and Zn were similarly distributed within the drainage basin. The correlation analysis exhibited that dissolved Ni an…

Effects of Soil Properties on K Factor in the Granite and Limestone Regions of China
Soil erosion has become a serious ecological problem in many catchments. Soil erodibility K factor can be estimated based on a series of soil properties, however, the identification of dominant soil properties that affect K factor prediction at different soil types has been little concerned. In this study, 3 soil profiles from the Jiulongjiang River Catchment (JRC) of granite region in Fujian province and 18 soil profiles from the Chenqi Catchmen…

C and N species, including dissolved organic carbon (DOC), dissolved inorganic carbon (DIC), dissolved organic nitrogen (DON), NO3 - and NH4+ contents in 57 river water samples collected from the Mun River of Thailand were measured to determine the relationships between these dissolved load species and their impacts on the environment. DOC values varied between 1.71 and 40.08 mg/L, averaging 11.14 mg/L; DON values ranged from 0.20 to 1.37 mg/L, w…
Stable H-O Isotopic Composition and Water Quality Assessment of Surface Water and Groundwater
In order to understand the water cycle and assess the water quality for irrigation purposes in the Upper Pi River Basin (UPRB), which is the northern slope of the Dabie Mountains, 68 surface water and groundwater samples were collected and analyzed for H-O isotopes and hydrochemistry during the high-flow season in 2017 and 2018. The results show that ranges of hydrogen and oxygen isotopic composition (δ 2 H: -68.8‱ to -40.8‱, δ 18 O: -10.05‱ to -…
Distribution, Sources and Water Quality Evaluation of the Riverine Solutes
To examine the chemical composition, potential sources of solutes, and water quality of Lancangjiang River, the concentrations of major ions (Ca 2+ , Mg 2+ , Na + , K + , HCO 3 - , SO 4 2- , Cl - and NO 3 - ) in 45 river water samples collected in July and August 2019 were determined. Ca 2+ and HCO 3 - are the predominant ions in river water. The extremely low K + and NO 3 - concentrations and the sparse population suggest that the anthropogenic …
Spatial Variation and Controlling Factors of H and O Isotopes in Lancang River Water, Southwest China
Climate changes and other human activities have substantially altered the hydrological cycle with respect to elevation. In this study, longitudinal patterns in the stable isotopic composition (δ 2 H and δ 18 O) of Lancang River water, originating from the Qinghai-Tibetan Plateau, are presented, and several controlling factors in the wet season are hypothesized. Lancang River water δ 2 H (-145.2‱ to -60.7‱) and δ 18 O (-18.51‱ to -8.49‱) were low …
The Mercury Behavior and Contamination in Soil Profiles in Mun River Basin, Northeast Thailand
To determine the geochemical characteristics and contamination of soil mercury in the Mun River basin, northeast Thailand, the vertical mercury distribution patterns and mercury contamination levels in six soil profiles under different land uses are studied.

Effects of Soil Aggregate Stability on Soil Organic Carbon and Nitrogen under Land Use Change in an Erodible Region in Southwest China
Soil aggregate stability can indicate soil quality, and affects soil organic carbon (SOC) and soil organic nitrogen (SON) sequestration. However, for erodible soils, the effects of soil aggregate stability on SOC and SON under land use change are not well known. In this study, soil aggregate distribution, SOC and SON content, soil aggregate stability, and soil erodibility were determined in the soils at different depths along the stages following…
