Trends In Metal (Pb, Zn, Ni, As And Se) Concentrations In The New Jersey Air Environment, Geoffrey Ike Ejiofor
Theses
The trend and atmospheric concentrations of five trace elements (Pb, Zn, Ni, As and Se) were studied at Newark (urban site) and Ringwood (rural site), New Jersey, during January - September 1985, whilst the Hackensack Meadowlands, New Jersey were monitored during October 1985-March 1986. The analytical procedure involved collection of the airborne particulates on a glass fiber filter using a non-dichotomous high volume sampler. The samples were digested and analyzed using the atomic absorption spectrophotometer. It was ascertained that Newark and Meadowlands exhibited higher average concentrations of Zinc and Lead than Ringwood. It was concluded all the metals originated mostly …
