Importance of environmental chemistry
The branch of science which deals with the chemical changes in our environment known as environmental chemistry. Thus the major component in our environment is air, water, soil, and sunlight. But when we study broadly our environment contain mainly three main components which are
Abiotic components of our environment
Any non-living component used in our ecosystem known as abiotic components. Thus sunlight, O2, N2, temperature, pH scales, and water is the non-living factors present in our environment. These are present in the lithosphere.
Biotic components of the environment
The living component of our environment is known as biotic. Thus plants, animals including man are the abiotic factors present in our environment.
Energy components of the environment
Energy components are globally leading end-to-end hydrocarbon for production and transport to sales for revenue generation. Hence these include solar energy, geochemical, thermochemical, hydroelectric and nuclear energy.
Elements responsible for the origin of life
Origin of life on earth timeline 3 billion years ago after changes in our environment.
In 1953 Miller and Urey showed that lighting discharges through a mixture of methane, water and ammonia, and hydrogen. Therefore it produces a significant amount of amino acids which is the essential product of the life cycle.
Abelson showed that solar ultraviolet ray acts on CO, CO2, N2 and a small amount of HCN. But glycine, adenine, and other biological significant product formed by the reaction of HCN and other biological factors. Therefore these compounds undergo a series of chemical complex evaluations over millions of years to produce living organisms.
Photosynthesis appeared approximately 2.5 billion years ago in the earth’s atmosphere. Therefore our earth becomes gradually reach with dioxygen and sustains the aerobic of life. Thus these diverse biological process of today has largely developed with this form of life.
Ecosystem diversity definition and examples
The existence of animals, plants, and microorganisms or biotic component living organisms and abiotic or non-living material which may be inorganic CO2, N2, sulfur, and phosphorus or organic protein and carbohydrates and climate factors like temperature and humidity is called an ecosystem.
- Thus an ecosystem is the coexistence of the population of all species of living, nonliving live together in a particular area.
- An ecosystem is the living organism’s presence in his physical environment.
- In other words, ecosystems are different types and sizes of the community namely marine, aquatic, or terrestrial. Therefore the marine in the ecosystem present in sea and ocean to connect living organisms in the sea and non-living organisms in a seawater environment.
- The law of conservation of energy follows in every ecosystem by conservation of matter into energy and energy into matter.
Harmful chemicals in our environment
The main aim of the environmental chemistry studies of environmental pollution and remedial measure necessity to free it from this environmental pollution.
A pollutant is a substance, chemical or factor which has the potential to adversely affect the natural characteristic of environmental, natural resources and assets. Acid rain is such a type of pollutants that affects our natural resources.
Thus to save our environment from this pollution we need to recycle household wastage, which included sewage and garbage, much toxic industrial wastage.
Therefore the concept of green chemistry was introduced in 1990 for protecting our environment from toxic elements used in or daily life. The production of substances of daily use by chemical reactions neither employ toxic chemicals nor release toxic elements in the atmosphere.
Hence the effort has been made by use chemicals from various chemical reactions. In the presence of UV light, sound waves, microwaves, and enzymes harmful to our environment.
