Chemistry and Protection of Environment

Over the years we have made significant developments in agriculture energy industry and health that have contributed to human well-being. However some of these improvements in our lives have resulted in changes to the environment around us. Many people think that chemistry, as well as chemical industries, are harmful to the environment. However nowadays environment protection has become the most important issues.Back years ago many new advances and scientific researches in the field of chemistry were started to develope to invent more environment-friendly applications and objects while they held keep up with the lifestyle we expect.An example of environment-friendly chemistry is green chemistry.The environment protection agency (EPA)defines green chemistry as the design of chemical products and processes that reduce or completely exterminate the use or generation of hazardous substances.Main researches on green chemistry aim to minimize or eliminate the formation of harmful-products and to maximize the desired products in an environment-friendly way.Chemically wastewater polluted soil and air treatment techniques(chemically clean up of environment) are also applied for the removal of heavy metals oil and greases suspended matters and emulating organic substances organic and inorganic substances difficult to decompose non-polar organic substances toxic pollutants and high salt concentration from environment.In this lecture, some examples of green chemistry and also a few of chemically clean up techniques will be presented.
