Chemical and Mineralogical Characteristics of Dry Deposition
in the Surrounding of a Cement Factory in Jordan
Dry deposition samples were collected from 28 residential rooftops in Fuhais,Jordan,during the dry seasons of the year 2004.The
samples were analyzed for trace and heavy metal concentrations to investigate the impact of total suspended particles emitted from the
cement industry in the city of Fuhais.The cement factory has been operational for the past 50 years,and themanagement was evaluating
the use of petcoke blending to reduce fuel costs.No baseline data on heavy metals due to the current operations existed prior to this
study.The present study showed that lead (Pb) and copper (Cu) concentrations were statistically signi?cant in the northwest sector of the
city compared with the other quadrants.This signi?cance was attributed to the heavy traf?c of trucks carrying raw materials and cement
in and out of the cement factory as the main route of transportation to the factory runs through this quadrant of the city.Cadmium
(Cd),aluminum (Al),iron (Fe),zinc (Zn),manganese (Mn),nickel (Ni),molybdenum (Mo),and chromium (Cr) concentrations were
high in all sampled areas.The overall average concentrations of all elements except Mo were found to be higher on the rooftops of the
residential areas in Fuhais City in comparison with a remote reference site near Amman where no anthropogenic activity exists.The
trace and heavy metal concentrations and the mineralogical composition of dry deposition samples collected from residential rooftops
are representative of the current cement industry operations,which dominate the air quality of Fuhais City.

Introduction
The Jordan Cement Factory (JCF) has been operational in the
city of Fuhais about 5 km outside the great municipality of
Amman,Jordan,since 1954.The JCF plant is located in the
center of the city of approximately 12,000 inhabitants.There
are schools,shops,a nursing home,and a hospital locatedwithin
1kmof the JCF site.Fuhais is located in a valley surrounded
by different land uses consisting of residential,commercial,and
agricultural activities.
An environmental audit and air-quality impact assessment
conducted in Fuhais concluded that total suspended particu-
late (TSP) concentrations downstream of the pollution-control
devices exceed design speci?cations and that the monitoring
programs for air quality around JCF need to consider more pa-
rameters (e.g.,heavy metals) and need to be more extensive and
frequent (Senes Consultants and Al Shamil Engineering,2003a,
2003b).The current JCF operation has exceeded the Jordanian
air quality standard for particulatematter less than 10 μmin size
(PM10),and the facility is one of the major contributors to over-
all atmospheric particulate loading in the vicinity of the plant
