“…The Jialu River (JR), the secondary tributary of the Huaihe River, is severely contaminated by a variety of contaminant sources such as a large number of trade waste and the untreated or lightly treated sewage waste in some cities (Zhang et al, 2009). These wastes have resulted in elevated concentrations of chemical oxygen demand (COD) and ammonia nitrogen (NH 3 -N) in water within the Zhengzhou region (Lu et al, 2008) and the lower reaches in the Zhoukou region (Zhao et al, 2005;Xie et al, 2008).…”

Abstract. The Jialu River, a secondary tributary of the Huaihe River, has been severely contaminated from major contaminant sources, such as a number of untreated or lightly treated sewage waste in some cities. Groundwater along the river is not an isolated component of the hydrologic system, but is instead connected with the surface water. This study aims to investigate temporal and spatial variations in water chemistry affected by humans and to characterize the relationships between surface water (e.g. reservoirs, lakes and rivers) and groundwater near the river in the shallow Quaternary aquifer. Concentration of Cl − in north Zhengzhou City increased prominently due to the discharge of a large amount of domestic water. Nitrate and potassium show maximum concentrations in groundwater in Fugou County. These high levels can be attributed to the use of a large quantity of fertilizer over this region. Most surface water appeared to be continuously recharged from the surrounding groundwater (regional wells) based on comparison surface water with groundwater levels, stable-isotopes and major ion signatures. However, the groundwater of a transitional well (location SY3) seemed to be recharged by river water via bank infiltration in September 2010. Fractional contributions of river water to the groundwater were calculated based on isotopic and chemical data using a mass-balance approach. Results show that the groundwater was approximately composed of 60-70 % river water. These findings should be useful for a better understanding of hydrogeological processes at the riveraquifer interface and ultimately benefit water management in the future.

“…The level of APs and APEs in the environment has been documented in many studies around the globe. NP, OP, octylphenol ethoxylates (OPEs) and NPEs have been detected in air, wastewater, surface water, sediment, sludge and biota samples (Rudel et al, 2003;Petrovic et al, 2003;Esperanza et al, 2004;Micic & Hofmann, 2009;Zhang et al, 2009;Grund et al, 2011;Wang et al, 2012;Chokwe et al, 2015b). A schematic diagram showing the emission, distribution and exposure pathway is given in Fig.…”

“…Concern has increased about relatively stable degradation products of APEs, alkylphenols (APs) such as nonylphenol (NP) and octylphenol (OP) (Zhang et al, 2009). APs have been classified together with lower ethoxylates (mono-tri), as endocrine-disrupting compounds (EDCs), because of their effects on the hormonal system of numerous organisms by competing with oestrogen for binding receptors (Gibble and Baer, 2003;Bonefeld-Jorgensen et al, 2007).…”

Alkylphenols (APs) are ultimate breakdown products of alkylphenol polyethoxylate (APEs) that are used in cleaning and industrial processes. The most commonly used APEs in the market are the nonylphenol ethoxylates (NPEs) and octylphenol ethoxylates (OPEs). As a result of their widespread use and their lipophilic nature, these compounds are ubiquitous in the environment and are currently of concern because of their toxicity, oestrogenic properties and widespread contamination. This review summarizes the concentrations of NPE and NP in different environmental media. The sources of NPE in the environment and toxicity are reviewed. Their distribution patterns in the environment as well as exposure pathways are discussed with a view to provide better understanding of these emerging environmental contaminants. It is envisaged that this review will heighten the importance of identifying emerging issues and data gaps, and generate a future research agenda on APEs.

“…According to studies conducted by 3,[6][7][8] an estimated 200 or more severe water pollution happened throughout the Huai river basin channels. [6][7][8] There is presence of organic pollution prevailed in Huai River especially in tributaries such as Jialu River 9 and the Jiangsu. 7,10,11 Nevertheless, much is not done in terms of the effects of hydrochemistry caused by human actions on the Huai River.…”

The causal research design method is most effective in establishing the cause-andeffect associations especially when carrying out findings concerning specific variations on water resources availability and development in relation to several other River Basin operating factors such as human activities, climatic conditions and Land-use. The paper takes advantage of specific scenarios to reveal the trends of relationships between factors measured. It is feasible to analyze the effect and cause for wide range of processes in relation to trends. There are higher levels of internal validity associated with research design method because of systematic subject selection. Present study examines the effects of climate change factors on the processes and relative needs for water uses in domestic, production and eco-water consumption is central to the allocation and conservation of water resources in systems of ecology and economy in arid Northeast of China. The population growth requires adequate supply of water especially during shortages arising melt-water from ice and glacier, abnormal rainfall, and flood disasters. The Soil and Water Assessment Tool (SWAT) has deployed prominently for modelling the physical distribution of hydrology of Huai River Basin to ascertain the influence of land use and climate changes independently. However, its inadequate data causes equivocal and inconsistency results derived from statistical analysis; seemingly poor control measures in the basin; method's cause-effect nature; and restriction to small and headwater basins. The watershed method revealed the effects of climatic conditions and human activities on water resources. However, it is limited by the constant variation to land use patterns usually smaller in large catchments than in small watersheds. There are two small neighbouring watersheds could have same climatic input but not in the case of larger catchments. To solve those problems researchers and stakeholders must find a long-term solution by identifying the affected areas. This paper presents the overview of water resources problem of the basin for future study, plan, and work. Keywords: The effects of human activities, climatic conditions and land-use factors on water resources development in huai river basin northeast china 108Copyright: ©2018 Othman Ali et al.The processes of hydrology are majorly caused by climate and land use. There is ever increasing rate of human advancements giving rise to intense changes universally both in climatic conditions and forms of land-use in catchments. In general, the effects of these changes on environment and ecological advancement are receiving extensive attention.12-15 On a catchment scale, the effects of these processes of hydrology including infiltration, groundwater recharge and runoff continue to adversely take tolls in the sense of balance of water resources' demand and supply and quality of water; thereby causing imbalances in environment, ecosystems, and economy at large. The direct consequences of land use change are ra...
