Chemical and toxic pollutants such as PAH that exist in aquatic environment come from various sources such as from industrial, urban and also by human activities. This compounds will be carried along the coastal and estuarine waters. PAH are recalcitrant and can persist in the environment for long periods of time.It is also present in most effluent as a complex mixtures and it is difficult to be removed by conventional remediation techniques. PAH is highly soluble in human blood and can cause cancer. With this book, your question on how PAH that exist in aquatic environment can be degraded without applying any phsio-chemical or through conventional remediation. The answer? Bioremediation. However the current technique involves the uses of microbe in removing pollutants. Applying the microbes directly is scary! You are introducing another so-called contaminant into the environment. With that, a new alternative sophisticated technique of bioremediation process was researched with the main aim to protect and preserve the ecosystem.
