Understanding the metal pollution can help governments and estuary management groups manage inputs. Here, we comprehensively analyzed behaviors of seven metals Cd, Zn, Cu, As, Pb, Cr, Hg in water responses these to hydrological connectivity Pearl River Estuary. The analyses were based on field measurements August-2016 January-2016 upper river mouth. We also assessed ecosystem health metals. Overall, this had an overall moderate level, with occasional severe perturbations. mean concentration...

How phytoplankton responded spatiotemporally to the co-occurrence of multiple variables is central importance for ecosystem management. In this study, extensive investigations in Pearl River estuary (PRE), southern China, between 1974 and 2017 revealed a strong anthropogenic effect on environmental drivers dynamics (in terms chlorophyll a). The empirical cause-and-effect chain summarized as human activity → hydrology nutrient may constitute fundamental quantitative tools predicting effects...

Nutrient enrichment and its quantitative cause-effect chains of the biogeochemical processes have scarcely been documented in Pearl River Estuary (South China). Field investigations nutrient samples taken between 1996 2018 showed significant differences nitrogen phosphorus with times sites. The concentrations DIN DIP gradually increased over past two decades, good fitted linear curves (R 2 = 0.31 for DIN, R 0.92 DIP); while temporal variation DSi was non-significant. Higher levels silicate...

Shoals and troughs are the fundamental geomorphological units of estuarine systems. However, their definition morphodynamic characteristics, influenced by complex dynamic environment, remain a critical challenge. This work introduces depth–area spatial function as quantitative criterion for shoals troughs, while simultaneously elucidating geodynamic implications. The Lingdingyang Bay (LDB) Pearl River Estuary serves case study. From 1901 to 2018, LDB consisted West Shoal, Middle East Shoal...

Abstract Traffic engineering is usually huge and requires a lot of construction resources. The use solid waste materials instead traditional building can effectively reduce resource consumption. Based on the example Jishang Expressway (Jiaxiang to Jinxiang section), this paper carried out research mix ratio design carbon emission reduction auxiliary components multi-source traffic engineering. Through compressive strength test, freeze-thaw cycle life assessment method, road performance...

Abstract In this study, we examine the decadal variability of tidal dynamics in terms range Pearl River Delta (PRD) from 1950s to 2016. The Mann–Kendall trend test and Empirical Orthogonal Function (EOF) method are employed identify long‐term trends spatial patterns annual series observed at 26 stations over whole PRD, respectively. results show that most display an increasing trend, except for some near estuarine outlets, which corresponds 1st EOF mode characterized by a rapid increase...

The Pearl River estuary is an ecologically dynamic region located in southern China that experiences strong gradients its biogeochemical properties. This study examined the seasonality of nutrient dynamics, identified related environmental responses, and evaluated how river discharge regulated sink source. field investigation showed significant differences dissolved nutrients with seasons three zones regarding estuarine characteristics. Spatially, exhibited a clear decreasing trend along...

Based on field efforts in Lake IJssel (the Netherlands) from 2000 to 2010, dynamics of 15 priority PAHs suspended particulate matter (SPM) and seawater were determined. This study examined time-varying changes PAH concentration composition, apportioned potential anthropogenic sources, quantified their linkages hydrological factors. The sum individual (defined as ∑15 PAHs) varied widely throughout the period IJssel, ranging 0.76 9.66 mg/kg SPM 0.014 0.136 μg/L seawater. High molecular weight...
