Atmospheric concentrations of organophosphates : At background stations in Sweden (Råö, Norunda) and Finland (Pallas)
Organophosphate esters (OPEs) are a group of chemicals that have been used for more than a century. OPEs are widely used as flame retardants, plasticizers, anti-foaming agents and as additives in lubricants and hydraulic fluids. The results of a screening assessment carried out by Umeå University in...

Organophosphate esters (OPEs) are a group of chemicals that have been used for more than a century. OPEs are widely used as flame retardants, plasticizers, anti-foaming agents and as additives in lubricants and hydraulic fluids.
