When conducting research, a literature review is an essential part of the project because it covers all previous research done on the topic and sets the platform on which the current research is based. No new research can be taken seriously without first reviewing the previous research done on the topic. To conduct a literature review, researchers must first find all previous research done on the topic they are studying. This review of the literature provides a thorough introduction to the reader on the topic and presents all the analyses and findings of previous studies. Current researchers use these findings to develop their own research questions and eventually to create their own hypotheses on the topic that provides a focus for their explorations and analyses. The findings of the current research can then be compared and contrasted with previous findings and used as takeoff point for further research.

Research review: Health Benefits of Negative Ions
Air ionization is known for decades, as is the correlation between negative ions and air quality: the more negative ions in the air, the less polluting particles. In urban environment, and especially inside buildings, negative ions are missing. To assess the nocivity of this lack of negative ions, scientists have studied the influence of air ionization on our physiology. Here are some picks from their research results.
Raymond A. Wuana, Felix E. Scattered literature is harnessed to critically review the possible sources, chemistry, potential biohazards and best available remedial strategies for a number of heavy metals lead, chromium, arsenic, zinc, cadmium, copper, mercury and nickel commonly found in contaminated soils. The principles, advantages and disadvantages of immobilization, soil washing and phytoremediation techniques which are frequently listed among the best demonstrated available technologies for cleaning up heavy metal contaminated sites are presented. Remediation of heavy metal contaminated soils is necessary to reduce the associated risks, make the land resource available for agricultural production, enhance food security and scale down land tenure problems arising from changes in the land use pattern.
