Temporal variations of black carbon during haze and non-haze days in Beijing
Black carbon (BC) aerosol has been identified as one of key factors responsible for air quality in Beijing. BC emissions abatement could help slow regional climate change while providing benefits for public health. In order to quantify its variations and contribution to air pollution, we systematically studied real-time measurements of equivalent black carbon (eBC) in PM2.5 aerosols at an urban...
متن کاملSize-resolved source apportionment of particulate matter in urban Beijing during haze and non-haze episodes
Additional size-resolved chemical information is needed before the physicochemical characteristics and sources of airborne particles can be understood; however, this information remains unavailable in most regions of China due to lacking measurement data. In this study, we report observations of various chemical species in size-segregated particle samples that were collected over 1 year in the ...
متن کاملMethane Photochemistry and Haze Production on Neptune
A numerical model was used to study methane photochemistry in the stratosphere of Neptune. The observed mixing ratio of methane, 2%, forces photolysis to occur near the CH4 homopause. For an assumed nominal value of the eddy mixing coefficient of 106 cm 2 sec -1 at the CH4 homopause, the predicted average mixing ratios of CzH6 and C2Hz, 1.5 x 10 -6 and 6 x 10 -7, respectively, agree well with o...
متن کاملIsotopic Constraints on Biogeochemical Cycling of Fe
INTRODUCTION Cycling of redox-sensitive elements such as Fe is affected by not only ambient Eh-pH conditions, but also by a signifi cant biomass that may derive energy through changes in redox state (e. The evidence now seems overwhelming that biological processing of redox-sensitive metals is likely to be the rule in surface-and near-surface environments, rather than the exception. The Fe redo...
