Quantitative relations between biomass and organic/inorganic resuspended particulate matter [PDF]

, 1998
During a period of two years, organic and inorganic suspended particulate matter and phytoplankton biomass was frequently measured in Lake Erken, a moderately deep, eutrophic lake in south-eastern Sweden.

Soil depth distribution of particulate organic carbon and nitrogen in the southeastern United States

Agricultural & Environmental Letters
Particulate organic matter may be an important component feeding soil microbial activity. This study described population‐level statistics of particulate organic carbon (C) and nitrogen (N) in predominately Ultisols across 181 farms throughout North ...

Secondary organic aerosol formation from in-use motor vehicle emissions using a potential aerosol mass reactor. [PDF]

, 2014
Secondary organic aerosol (SOA) formation from in-use vehicle emissions was investigated using a potential aerosol mass (PAM) flow reactor deployed in a highway tunnel in Pittsburgh, Pennsylvania. Experiments consisted of passing exhaust-dominated tunnel
