Heavy metals and metalloids are an increasing environmental problem worldwide. Some industrial activities and agricultural practices increase their level in the substrate and the possible introduction of these elements in the food chain is an increasing human health concern. The protection and restoration of soils and water contaminated with heavy metals generate a great need to develop efficient adsorbents for these pollutants. Agricultural fertilizers which contain small amounts of cadmium and lead is widely applied and used in Iran. However, both these heavy metals remain below toxic levels. In contrast, contamination of lowland rice fields by sewage sludge from textile plants and some mining has increased the heavy metal content of the soil and reduced rice yields in these areas (Mazandaran province). Currently remediation of polluted soil is being carried out, using plants such as Vetiveria zizanioides and Eichornia crassipes, plus applications of zeolite in some areas of Meandering province of Iran. This mini review firstly indicate general objectives about remediation and then deal with to some activies about agricultural soil remediation that contaminated with some heavy metals (specially, Pb and Cd in Mazandaran province of Iran. We conclude that above mentioned species, may be an effective species for phytoextraction and should be tested for this purpose in field conditions. |

The research work was conducted to investigate the serum antibody response
againstListeria ivanoviiin experimentally infected rabbits by inoculation
method. It was found out that the blood monocyte count was increased, from 2-3% (prior injection) up to 15% to 72 hours post injection and the count declined
after 120 hours. There was a significant rise in mononuclear cells after the
repetition of doses except that the level was maintained during these intervals.
The highest antibody level was observed at 14-15 days post-inoculation, which
persisted for more than three months. These findings suggest that an association
exists between the increased number of monocytes in the blood and humoral
immune response in correlation with the resistance against listeric infection. |
