Climate change is predicted to result in rising average temperature of seawater with more extreme thermal events, and frequent rainfalls some coastal regions. It imperative understand how naturally mediated changes salinity can modulate toxicity chemical contaminants marine life. Thus, this study investigated combined effects on zinc oxide nanoparticles (ZnO-NPs) the diatom Thalassiosira pseudonana. Because ZnO-NPs formed larger aggregations released less ions (Zn2+) at greater salinity, T....
Because of wide applications surface-modified zinc oxide nanoparticles (ZnO-NPs) in commercial sunscreens and their easiness being released into water, concerns have been raised over potential effects on aquatic organisms. This study compared physicochemical properties silane-coated uncoated ZnO-NPs to elucidate toxic potencies toward three freshwater marine microalgae. Surfaces (20 nm) were modified by coating with 3-aminopropyltrimethoxysilane (A-ZnO-NPs) that provides the particles a more...
Temperature and salinity can significantly modulate physicochemical properties toxicity of ZnO-NPs. Existing water quality criteria are inadequately protective towards marine organisms, especially in estuaries under global climate change.
Water quality guidelines and ecological risk assessment of chemical substances like nickel (Ni) in tropical regions such as South East Asia Melanesia are often based on temperate information a result fewer Ni ecotoxicity data available for species. This leaves an unknown margin uncertainty the tropics. In order to fill this gap, study was designed conduct standard toxicity tests with two freshwater species (acute tests) three marine chronic originated from Hong Kong. All were carried out...
Coated zinc oxide nanoparticles (ZnO-NPs) are more commonly applied in commercial products but current risk assessments mostly focus on bare ZnO-NPs. To investigate the impacts of surface coatings, this study examined acute and chronic toxicities six chemicals, including ZnO-NPs, ZnO-NPs with three silane coatings different hydrophobicity, bulk particles (ZnO-BKs), ions (Zn-IONs), toward a marine copepod, Tigriopus japonicus. In tests, hydrophobic were less toxic than hydrophilic Analyses...
In early August 2017, a serious palm stearin pollution accident occurred in the Pearl River Estuary, South China. While there were already several oil related spills around world, ecological effects and risks of such accidents to coastal marine environments remain largely unknown. this study, we found that all seawater sediment samples collected from six sites heavily contaminated by within 1 week accident, their levels significantly decreased preaccident after four months. Waterborne...
The Mugilogobius group consists of brackish water gobionellines widely distributed in the Indo-West Pacific region. Complete mitochondrial genome and morphological evidence was collected to estimate their phylogenetic relationship taxonomic status. A total 11 genera were sampled, including Brachygobius, Calamiana, Hemigobius, Mugilogobius, Pandaka, Pseudogobiopsis, Pseudogobius, Redigobius, Rhinogobius, Stigmatogobius, Wuhanlinigobius, five which sequenced for first time. tree also...
Shih-Pin Huang, I-Shiung Chen, Mana M. N. Yung, and Kwang-Tsao Shao (2016)Mugilogobius mertoni (Weber, 1911) is considered as a widely distributed species around the Indo- West Pacific region, several nominal are junior synonyms of mertoni. However, in our recent study, different morphological types were observed, they collected from Taiwan, Palau Phuket Island. This study aimed to investigate taxonomic status those mertoni-like individuals, we also attempted assess their phylogenetic...
The occurrence and fate of 14 widely used phthalic acid esters (PAEs) in a wastewater treatment plant (WWTP) located Guangzhou, China were investigated for 1 y.Results showed that PAEs detected but the levels effluent below international standard.Seasonal variation influent was observed, with higher winter spring lower summer autumn.The mean overall removal efficiency 70.9% WWTP.Results also indicated PAE pollution sewage sludge more severe than previous report Guangzhou.The annual emission...
