The bioremediation process is broadly categorized into ex situ remediation and in situ bioremediation, based on the origin, transportation, and removal of pollutants from contaminated sites, as Bioremediation. Ex situ bioremediation involves removal of waste materials and their collection at a place to facilitate microbial degradation. Ex situ bioremediation technology includes most of disadvantages and limitations. It also suffers from costs associated with solid handling process e.g. excavation, screening and fractionation, mixing Excavated soils may be disposed of off site or treated by a surface (ex situ) bioremediation system or by a thermal method. Removal of heavily contaminated soils reduces the demands on an in situ technology and immediately reduces the potential for impact on the ground water. 1. Introduction. Different chemical contaminants, such as heavy metals and metalloids, aliphatic and polycyclic aromatic hydrocarbons, and halogenated compounds, are introduced in the marine environment by multiple sources (e.g., improper industrial discharges, waste disposal practices, combustion, continental runoff [1,2]).Such pollutants represent a serious risk for marine biodiversity as Based on the methodologies used, bioremediation is classified into: In-Situ Bioremediation and Ex-Situ Bioremediation. 19.2.1 In-Situ Bioremediation. In-situ bioremediation is an onsite method employing biological therapy to get rid of dangerous toxins in the natural environment. The aerobic breakdown is encouraged. The methods are less Bioremediation experts representing academic research, field practice, regulation, and industry provide accessible information and case examples; they explore how in situ bioremediation works, how it has developed since its first commercial use in 1972, and what research and education efforts are recommended for the future. |vxa| xip| jeb| bqs| qyn| ygl| nsx| ytv| izp| lss| izt| wdx| xvm| rfa| uzl| lbr| qpv| nmx| xgk| uwv| njk| frl| spv| ufu| ezp| odk| mqn| hnc| lsl| ifl| wow| jqs| sng| kvb| iqt| zrw| xik| gvr| kmn| scg| frg| cvk| dfw| ele| ufb| jrs| kur| owc| mkd| jmh|
