Abstract

Coastal ecosystem health is of vital importance to human well-being. Field investigations of major pollutants along the whole coast of China were carried out to explore associations between coastal development activities and pollutant inputs. Measurements of target pollutants such as PFAAs and PAHs uncovered notable levels in small estuary rivers. The Yangtze River was identified to deliver the highest loads of these pollutants to the seas as a divide for the spatial distribution of pollutant compositions. Soil concentrations of the volatile and semi-volatile pollutants showed a cold-trapping effect in pace with increasing latitudinal gradient. The coastal ecosystem is facing high ecological risks from metal pollution, especially copper (Cu) and zinc (Zn), while priority pollutants of high risks vary for different kinds of protected species, and the ecological risks were influenced by both climate and physicochemical properties of environmental matrices, which should be emphasized to protect and restore coastal ecosystem functioning.

Abstract

A new and efficient fluorescent sensor 4′-hydroxy-3′-[(4-antipyrineimino)methyl]-4-biphenylcarboni- trile(L) was prepared for the selective detection of Zn2+in aqueous ethanol medium. When excited at 419 nm, the fluorescent intensity of sensor L at 507 nm was remarkably increased more than 54-fold after adding Zn2+ions. The strong green emission of the solution can be easily identified by naked eye under UV light. Thus, sensor L behaves as a naked eye fluorescent “turn on” detector for Zn2+ions. The fluorescence enhancement might be attributed to the inhibition of excited state intramolecular proton transfer(ESIPT) and C=N isomerization as well as the chelation enhanced fluorescence(CHEF) effect. The complex solution of sensor L with Zn2+ions exhibited reversibility with ethylene diamine tetraacetic acid(EDTA) and the probe could be recycled for further use. Notably, sensor L could clearly distinguish Zn2+from Cd2+. The interaction of sensor L with zinc ions was investigated by means of FTIR, 1H NMR and HRMS spectroscopy. Furthermore, sensor L has been applied for cell imaging studies.
