Photocatalytic degradation of jellyfish polyps: A sustainable approach to combat jellyfish blooms.

Jellyfish blooms had been frequently occurred around the globe in recent decades, which had been extensively managed due to their serious ecological and socio-economic damage. However, the environment-friendly methods by eliminating polyps to early control the outbreaks of medusae from source had been rarely involved despite exiting some physical and chemical manners currently. A new approach to photo-catalytically inactivate polyps of Aurelia coerulea, was thus explored by synthesizing the P-g-CN photocatalysts modified with trace AgO in this study.

Bio-inspired synthesis of N-doped TiO/C nanocrystals using jellyfish mucus with high visible-light photocatalytic efficiency.

Non-metal doping of titanium dioxide (TiO) has been widely investigated, because it can facilely improve the optical response of TiO under visible light excitation in environmental pollution treatments. In the ongoing efforts, however, little consideration has been given to the use of harmful marine organisms as dopants. Here, we employed the natural mucus proteins of the large harmful jellyfish and , which have frequently bloomed in East Asian marginal seas in recent decades, to synthesize mesoporous nitrogen-doped TiO nanocrystals modified with carbon (N-TiO/C) by a simple hydrothermal method.

Organophosphate esters (OPEs) pollution characteristics, bioaccumulation and human consumption implication in wild marine organisms from the Yellow River Estuary, China.

As the substitutes of polybrominated diphenyl ethers, organophosphate esters (OPEs) with high concentrations have accumulated in the estuaries, bays, and harbors. However, limited information is available about the OPEs in the estuary organism categories, especially under the multiple industrial pressure. This study investigated the occurrence, bioaccumulation and human consumption implication in wild marine organisms from the Yellow River Estuary, where located many petroleum and chemical manufacturing industries.

Spatial and temporal variability and risk assessment of organophosphate esters in seawater and sediments of the Yangtze River estuary.

Organophosphate esters (OPEs) as substitutes for PBDEs have been widely detected in the marine environment, while little is known about the pollution characteristics and variation of OPEs in estuarine environments with complex hydrodynamic conditions and land-based input. Yangtze River Estuary (YRE) is a typical highly urbanized and industrialized estuary, with a complex hydrological environment and geochemical behavior. This study found that the concentrations of OPEs in both seawater and sediments in the YRE were higher in spring than in summer.
