Abstract
Air,The total amounts of mercury in the air marked varied from each study area and between the three study areas.
The concentration of total Hg in the air of El-Max varied from L2720 to 24350 ng/m3 according to distance and south east wind lirection. The amounts of Hg decreased with distance from the ”hot pot” and were higher with down wind direction than with upwind These amounts decreased to a level of 2500 ng/m3 and 3500 f/m3 in air samples collected at 3000 ra with north east and south »st wind direction respectively, relative to the level of 15500 f/m3 at the same distance and south east wind direction.
The amount of total Hg in air samples of Abo-Qir varied from iOO to 10400 ng/m3 with south east wind direction, and were lower sites not parallel with wind direction.
The amount of total Hg in the air of Kafr El-Zayat behaved in different way. The highest concentration of Hg in air (8000 f/m3) was at distance 1000 m from the ”hot spot”. This is due to ie emitted Hg was from stack which reach its maximum at a certain .stance depending on stack height then decreased by distance.
1.1.2. Soils
The concentration of total Hg in the soils of El-Max area iried from 2900 to 4740 ng/g in winter samples and from 8560 to $720 ng/g in summer samples. The atmospheric deposition of Hg on ie soils is greater in summer than in winter. The concentration Hg decreased with soil depth. The amounts of inorganic Hg in >ils were high and varied between 70 and 95% of the total and the :ganic Hg varied between 5 to 30% of the total.
The soils of Abo-Qir contained total Hg varying from 60 to 750 j/g soil. The highest amounts are found in summer soil samples. ie percent of organic Hg in the soil varied from 5 to 31% of the jtal Hg, the amounts of Hg in soils decreased with soil depth.
