creator: https://orcid.org/0000-0002-8981-0805
alternative label: PBDE 25 and PBDE 28 mass concentration
broader: trace gas variables
broader: variable
definition: Mass concentration means mass per unit volume and is used in the construction mass_concentration_of_X_in_Y, where X is a material constituent of Y. A chemical species denoted by X may be described by a single term such as 'nitrogen' or a phrase such as 'nox_expressed_as_nitrogen'. PBDE 25 and PBDE 28 is a mixture of two compunds and belongs to the group of persistent organic pollutants known as polybrominated diphenyl ethers (PBDEs).
