“…All the metals and SEM components were significantly correlated with each other in the surface sediments of the Xiaoqinghe River, suggesting a major common origin of them in the sediments in this area. The wastewater discharged from human activities into the Xiaoqinghe River could be responsible for this (Wang et al, 2006). The concentrations of all the studied metals and the components of SEM were significantly correlated with the MC, which indicated that MC was an important impact factor for their spatial distribution, and this was consistent with the previous study in the offshore area of the Laizhou Bay .…”

a b s t r a c tSurface sediments in the Xiaoqinghe estuary, southwestern coastal Laizhou Bay, were examined to assess the bio-toxic risk of heavy metals (Cd, Cu, Ni, Pb and Zn) with the effects range-low and effects rangemedian guidelines (ERL-ERMs) and the concentration ratio of simultaneously extractable metals to acid volatile sulfides ([SEM]/[AVS]). Based on the ERL-ERM guidelines, bio-toxic effect caused by Cu, Ni, Pb and Zn could be expected in the riverine surface sediments of the Xiaoqinghe estuary; and the surface sediments in the marine area were in good quality and only Ni might cause bio-toxic effect occasionally. The AVS-SEM guidelines revealed that no bio-toxic effect could be caused by any of the studied metals in both the riverine and marine sediments, since there were excess sulfides in surface sediments which could form water-insoluble substances with free metal ions and reduce the bioavailability of heavy metals.

“…This finding is distinct from several other large Chinese river-estuarine systems that are controlled by similar influences of the East Asian monsoon and human activities. The Yellow River Estuary of North China shows simultaneous declines in water discharge [51] and nutrient fluxes. The Yangtze Estuary of East China shows increasing N/P fluxes and decreasing DSi flux [4][5][6][7], while its water discharge demonstrates no significant changes.…”

Distribution, fluxes and decadal changes of nutrients in the Jiulong River Estuary, Southwest Taiwan Strait

et al. 2012

The Jiulong River Estuary (JRE) is a typical subtropical macro-tide estuary on the southwest coast of the Taiwan Strait (TWS), which has been greatly impacted by human activities over the past 30 years. To understand nutrient dynamics and fluxes under such a heavy background of anthropogenic perturbation, eight cruises were conducted from April 2008 to April 2011, covering both wet (May to September) and dry (October to April next year) seasons. Nutrient concentrations were very high for the freshwater end-member in the upper reach of the JRE (nitrate (NO 3 In dry seasons, concentrations of these nutrients were higher than in wet seasons. Nitrate was the dominant chemical species of dissolved inorganic nitrogen (DIN), with percentages of 67%-96% in wet seasons and 55%-72% in dry seasons. Distributions of NO 3 -N and DSi against salinity were nearly constant during all cruises, and showed generally conservative mixing behaviors in the estuary (1

“…Ocean discharge has declined from 24 to 1 billion m 3 per year for the former (Jiang 2009), and from 48 to 13 billion m 3 per year for the latter since the 1950s (Wang et al 2006). Given the increasing scarcity of water in the north, it is not surprising that per capita water use in Beijing has declined sharply mainly due to water availability over the past 10 years ( Fig.…”

Water diversions facilitate spread of non-native species

et al. 2015

Many countries/areas are experiencing or may soon experience water scarcity owing to rapid population growth, urbanization and/or climate change. Currently, almost one-fifth of the world's population (1.2 billion) live in areas of physical water scarcity. Water diversions have become a commonplace solution proposed by governments for alleviation of physical water scarcity. Thus far, more than 80 major projects are completed or under construction globally, including the world's largest diversion: South-to-North Water Transfer Project (SNWTP) in China. Negative effects associated with water diversions, such as habitat loss and transfer of pollutants, have been recognized. However, it has been largely overlooked that ''invasion highways'' are created when water diversions link biogeographic regions. These ''invasion highways'' can facilitate spread of an array of non-native species. Although previous experiences have provided clear warnings regarding spread of non-native invasive species through artificial waterways, these lessons have been largely ignored by governments when resolving water scarcity problems. Here we use SNWTP, which will likely facilitate spread of invasive golden mussels, as well as many known examples of non-native invasive species spread through artificial waterways in other water systems, to call on governments to formally establish policy and seek management solutions to considering spread of non-native species when planning water diversions.
