Abstract:
... This work utilized the simplicity of a so-called membraneless vaporization (MBL-VP) unit as a gas separator for the colorimetric determination of ethanol in alcoholic beverages. A beverage sample with a volume of 1 mL was directly injected into a small container which was hung from a lid inside a closed 40 mL reused glass bottle without pretreatment such as distillation. An acidified potassium dic ...

Abstract:
... Air-sea exchange of POPs and PAHs was assessed in Concepción Bay during January, summer 2015. Results showed low levels, in air and water, for POPs (1–20 pg m⁻³, and 6–50 pg L⁻¹, respectively) and for ΣPAHs (1–2 ng m⁻³ and 1–2 ng L⁻¹, respectively). The highest levels were found for PBDEs (200–20,000 pg L⁻¹) in the water samples (3-fold times higher than PCBs and OCP) and PBDE209 accounted for 90% ...
