Environmental Risk Assessment of Polybrominated Diphenyl Ether (PBDE) and Hexabromocyclododecane (HBCD) in Ebro River Basin
(Universitat Politècnica de Catalunya, 2011-02)
Master thesis (pre-Bologna period)
Open AccessIn this study, a model for the evaluation of the environmental risk of polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD) for the aquatic organisms has been developed. These compounds are brominated ... -
Impact of HONO sources on the performance of mesoscale air quality models
(2012)
Article
Open AccessNitrous acid (HONO) photolysis constitutes a primary source of OH in the early morning, which leads to changes in model gas-phase and particulate matter concentrations. However, state-of-the-art models of chemical ... -
