^{3rd International Convention on} Geochemistry, Environmental Chemistry and Atmospheric Chemistry October 19-20, 2018 Ottawa, Ontario, Canada

Environmental Health is the field of science and mainly focused on the natural and built environments for the benefit of human health. Environmental health field tries to limit the harmful exposures through natural things such as soil, water, air food, etc. Environmental health and safety creates the physical work environment which encompasses the promotion and maintenance of the physical, mental and social well-being of employees or workers in the organization. It includes reducing work-related injury, illness and disability by addressing the harmful hazards and risks of the physical environment. Reducing physical job hazards may also reduce work related stress in employees in workplace.

The session of Environmental and Atmospheric chemistry is concerned with the study of the chemical and biochemical phenomena that occur in natural places. Today, this part of chemistry is covering every aspect of interdisciplinary science which includes atmospheric, aquatic and soil chemistry as well as possible solutions regarding the atmospheric problems.

Photochemistry is the branch of chemistry concerned with the chemical effects of light. For the industrial chemist, photochemistry is just one of the many means of producing chemical compounds or bringing them into reaction. However, it has some advantages over thermal, catalytic and other methods that immediately fascinate him. These include:
(1) Selective activation of individual reactants,
(2) Specific reactivity of electronically excited molecules,
(3) Low thermal load on the reaction system,
The main aim of preparative photochemistry is to reduce manufacturing costs for chemical products by introducing photochemical steps in the syntheses. Light-sensitive compounds have great technical significance in photography, reprography, and printing. Important applications have been also found in U.K.-curable paints, primers, and printing inks (4) exact control of radiation in terms of space, time and energy. Photo stabilizers are primarily used in plastics and man-made fibres. A Primary photochemical process of great theoretical and practical significance is luminescence. Photochemistry is an essential tool in both the manufacturing and the use of modern cars. Radiation curing is used as a very efficient, economically and ecologically attractive technology for the coating and bonding of many of the parts used in a car, and avoiding degradation of the coating due to photo induced processes during the foreseen service time is a key issue.

A biological system is a group of living beings in conjunction with the non-living parts. Biotic and abiotic parts are connected together through supplement cycles and vitality streams. Biological communities are controlled both by outside and inner variables. Outside variables, for example, atmosphere, parent material that structures the dirt and geography control the general structure of an environment. Biodiversity influences biological community work to do the procedure of aggravation and progression. 

Environmental innovation is the use of at least one of natural science, green science, natural checking and electronic gadgets to screen, model and ration the common habitat and assets, and to control the negative effects of human association. Feasible advancement markers are measures of manageability, and endeavour to evaluate past the non-specific idea. In spite of the fact that there are contradictions among from various controls and global associations have each offered measures while supportability pointer records and revealing frameworks increased developing prevalence in both general society and private parts. 

Biogeochemical cycle is a pathway by which a synthetic substance travels through both the biotic and abiotic parts of Earth. Biogeochemical discloses to us that organic, topographical and compound variables are included. There are numerous biogeochemical cycles that are as of now being considered interestingly as environmental change and human effects are radically changing the speed, power, and adjust of these moderately obscure cycles.

Hydrology is the scientific study of the movement, distribution, and quality of water on Earth and other planets, including the water cycle, water resources and environmental watershed sustainability. Hydrology subdivides into surface water hydrology, groundwater hydrology (hydrogeology), and marine hydrology. Domains of hydrology include hydrometeorology, surface hydrology, hydrogeology, drainage-basin management and water quality. 

Human population development, ascending according to capita material utilization, and troublesome advancements have made progress a worldwide environmental constrain. Human initiated worldwide natural changes perceive two expansive and covering field of study. Digestion examines the stream of materials and vitality through the chain of extraction, generation, utilization and transfer of present day modern culture.

Ecological instruction is a procedure that permits people to investigate natural issues, take part in critical thinking, and make a move to enhance the earth. It is a multi-disciplinary field incorporating orders, for example, science, science, material science, nature, earth science, air science, arithmetic, and topography.

Environmental chemistry is the scientific review of the chemical and biochemical phenomena that occur in natural places. Environmental chemistry can be described as the study of the sources, reactions, transport, effects of chemical species in the air, soil, and water environments; and the effect of human activity on these. Environmental chemistry is an integrative science that includes atmospheric, aquatic and soil chemistry, as well as uses analytical chemistry. It is allied to environmental and other areas of science. It is different from green chemistry, which tries to trim potential pollution at its source.

Whereas Environmental engineering deals with the combination of sciences and engineering principles to develop the natural environment, to provide healthy air, water, and land for human habitation and for other organisms, and to procure pollution sites.

Environmental biotechnology is a complex of scientific and engineering education related to the use of microorganisms and their products in the inhibition of environmental pollution through bio treatment of liquid, solid, and gaseous wastes, bioremediation of spoil environments, bio monitoring of environment and treatment processes. The aids of biotechnological treatment of wastes are as follows: diversity of the conditions suitable for biodegradation, biodegradation of a wide spectrum of hazard substances by natural microorganisms; availability of a wide range of biotechnological channels for complete wrecking of hazardous wastes; and diversity of the conditions suitable for biodegradation. The major considerations for utilization of biotechnology in waste treatment are technically and economically reasonable rate of detoxification of substances during biotechnological treatment, and ability of natural microorganisms to degrade substances. 

Green chemistry is the design of chemical products and processes that reduce or eliminate the use or generation of hazardous substances. Green chemistry applies across the life cycle of a chemical product, including its design, manufacture, use, and ultimate disposal. Green chemistry is also known as sustainable chemistry. Green chemistry reduces pollution at its source by minimizing or eliminating the hazards of chemical feed stocks, reagents, solvents, and products.

Environmental toxicology is the science and practices of the adverse effects mainly of chemicals other man-made agents in the environment and through the environment. The targeted receptors of these adverse effects may be both the ecosystem and the human. Environmental toxicology includes the study of chemical substances  potential and actual contaminants – polluting air, water, soil and food, their impacts upon the structure and function of ecological systems, including man as well as the use of these results for decision making and environmental management.

Mutagenicity refers to the induction of permanent transmissible changes in the structure of the genetic material of cells or organisms. These changes (mutations) may involve a single gene or a block of genes.

Petroleum Chemistry is made of a mixture of different hydrocarbons. The most prolific hydrocarbons found in the chemistry of petroleum are alkanes, these are also sometimes knows as branched or linear hydrocarbons.
