Evaluation of air pollution by heavy metals on bab El Oued zone of Algiers

The present study consists in analyzing the quality of the air in the capital. LVS pump (low volume sampler) was used for the collection of the samples in the district of Bab El Oued in Algiers characterized by the presence of a hospital and an incinerator of medical and different other waste as well as a strong density of traffic cars. The aerosols were taken at height of 3 m of the ground in total suspended particulate (TSP) mode. The samples have been analyzed by EDXRF (energy dispersive X-ray fluorescence). The experimental results show that the daily content of TSP are above limit of the target value 50 μg/m3. The TSP are respon-sible for the transport of toxic heavy metals such as Cd, Pb, Cr and N

Selenium content in wheat and estimation of the selenium daily intake in different regions of Algeria

In this work, we have measured the selenium content in wheat produced locally in eight different regions of Algeria from east to west, and we have established the annual consumption of selenium for five socio-professional categories. Instrumental neutron activation analysis is used. The selenium levels in wheat samples varied from 21 (Tiaret) to 153 mu g/kg (Khroub), with a mean value about 52 mu g/kg. The mean of selenium daily consumption from ingestion of wheat per person in the eight regions varied from 32 to 52 mu g/day which is close to the minimal FAO recommendation
