Abstract:
... An integrated Sequential Injection (SI)/Flow Injection (FI) system furnished with a miniaturized LED-based fluorometric detector is presented in this work for expedient bioaccessibility tests of orthophosphate in soils. Equipped with a microcolumn of conical shape containing 50mg of soil, the hybrid flow system was resorted to on-line dynamic leaching and real-time quantification of pools of mobil ...

Abstract:
... Effects of nitrogen (N) addition on the microbial degradation and uptake of a mixture of BDE-47 and -209 by Aegiceras corniculatum, a typical mangrove plant species were investigated. At the end of 3-month experiment, a significant dissipation of BDE-47 was observed in the planted soil, and this dissipation, particularly in rhizosphere soil, was significantly accelerated by the frequent addition o ...
