Chem. 340 2(2+0), course offered to meet the needs of students interested in cheemistry sciences, and provide them with the basic concepts of organic chemistry relevant to their further studies and life. All will be discussed and explored in detail. When you finish this course, you should be able to:
√ Classification of organic compounds
√ Nomenclature of common classes of organic compounds
√ Relationship between structure, physical and chemical properties
In order to assess the pollution levels of selected heavy metals, 45 bottom sediment samples were collected from Al-Kharrar lagoon in central western Saudi Arabia. The concentrations of the heavy metals were recorded using inductively coupled plasma-mass spectrometer (ICP-MS). The results showed that the concentrations of Pb and Cd exceeded the environmental background values. However, the heavy metal contents were less than the threshold effect level (TEL) limit. The concentrations of heavy metals in lagoon bottom sediments varied spatially, but their variations showed similar trends.
