| 摘 要： | It is estimated that the poisonous heavy metals released to the environment come up to million tons. Such great amounts of poisonous heavy metals result in a serious bane to ecosystem and human health. The valid control of spreading and pollution of heavy metals in the environment has hence become an urgent issue of the moment. In this study, through tameness and induction of living creature＇s tolerance from dirty mud, using microbial technology we have cultivated some anti-heavy-metal microbes able to resist the pollutions from poisonous chemical elements such as arsenic, chromium, cadmium, hydrargyrum, and plumbnm, four of which are fungi and five are bacteria. Atomic absorption spectroscopy and atomic fluorescence spectrophotometry analyses showed that, to the same chemical element, fungi have stronger resistance than bacteria by one time or so.

| Abstract: | In the Middle East, dust and sand storms are a persistent problem and can be inhaled into the mouth, nasal pharynx, and lungs due to the size and abundance of these micro-particulates. The chronic and acute pulmonary effects of this dust inhalation have not been well studied nor has the dust been effectively characterized as to its chemical composition, mineral content, or microbial flora. Scientific experiments were designed to study the Kuwaiti dust as to its physical, chemical, and biological characteristics for its potential to cause adverse health effects. First, dust samples from different locations were collected and processed. Secondly, initial chemical and physical characterization of each sample including particle size distribution and inorganic analysis was conducted. Finally, characterization of biologic flora of the dust, including bacteria, fungi and viruses, was performed. Initial data indicates that the mineralized dust is primarily composed of calcium and magnesium sulfates and carbonates with a variety of trace metals. |
