This study investigates the presence of microplastics (MPs) in seawater, sediments, and organisms along the coastal areas of Da Nang, Vietnam. The results obtained revealed MP concentrations ranging from 111 to 304 MPs/L in seawater and 2267 to 4600 MPs/kg in sediment. In organisms such as oysters, mussels, crabs, snails, and fish, MP levels ranged from 1.

- The study investigates the blank responses of gold-coated adsorption tubes in analyzing gaseous elemental mercury (Hg(o)) to minimize experimental bias using cold vapor atomic absorption spectrometry (CVAAS).
- It compares the findings to previous research on memory effects in cold vapor atomic fluorescence spectrometry (CVAFS), focusing on how different amounts of mercury and time intervals (1, 14, and 45 days) influence the results.
- The results suggest that both the initial mercury loading and the storage duration affect the release of excess mercury, indicating that memory effects may arise from mercury retained in the gold matrix and micro-/nanoparticles released during heating, rather than interference from other gaseous species.
Analysis of volatile organic compounds released during food decaying processes.
Environ Monit Assess
March 2012
A number of volatile organic compounds (VOCs) including acetone, methyl ethyl ketone, toluene, ethylbenzene, m,p-xylene, styrene, and o- xylene released during food decaying processes were measured from three types of decaying food samples (Kimchi (KC), fresh fish (FF), and salted fish (SF)). To begin with, all the food samples were contained in a 100-mL throwaway syringe. These samples were then analyzed sequentially for up to a 14-day period.
