OMICS International cordially invites all the participants to attend "International Conference on Pollution Control & Sustainable Environment" during April 25-26, 2016 at Dubai, UAE.
With the increase of the urbanization, humans were able to advance further into the 21st century. Technology developed rapidly, science became advanced and the manufacturing age came into view. With all of these came one more effect, environmental pollution. Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. There is general agreement that we must control pollution of our air, water, and land, but there is considerable dispute over how controls should be designed and how much control is enough.
This conference is all about promoting global health issues and advanced technologies used to control and regulate the pollution. This conference includes various types of pollutions, human impact on the environment, pollution risk assessment, advanced control methods.
The presence of gases, dust particulates, fumes or odour in large amounts which leads to harmful damage to the living beings and environment is called as air pollution. The air pollutants from automobile emissions, chemical odours and factory smoke are the sources.
The emission of particulate matter which is microscopic solid or liquid in air is particulate emission. Particulate emissions are visible in the form of soot or smoke. There are some effective methods which are used to control the air pollution. These are used to filter and purify the air which is polluted.
Waste Water Pollution
Waste water pollution is caused due to discharge of waste water from industrial and commercial waste into surface waters; untreated discharge of domestic sewage, chemicals into flowing surface waters and disposal of waste and leaching into ground water; eutrophication. The various methods of contamination of wastewater require a variety of strategies to remove the contamination. The various treatments are brine treatment, brine management, solids removal, oil and grease removal, hydro cyclone oil separators, removal of biodegradable organics etc.
Solid and Hazardous Waste Disposal
Solid waste is defined as waste that is generated by businesses from an industrial or manufacturing process or waste generated from non-manufacturing activities that are managed as a separate waste stream. Toxic waste, chemical waste, industrial solid waste and municipal solid waste are designations of solid waste.
The wastes may be found in different physical states such as gaseous, liquids, or solids. A hazardous waste is a special type of waste because it cannot be disposed of by common means like other by-products of our everyday lives.
Marine pollution occurs when harmful, or potentially harmful, effects result from the entry into the ocean of chemicals, particles, industrial, agricultural and residential waste, noise, or the spread of invasive organisms. Most sources of marine pollution are land based.
Pollutants enter rivers and the sea directly from urban sewerage and industrial waste discharges, sometimes in the form of hazardous and toxic wastes.
There are many causes of industrial pollution, the negative by-products of human industry. One of the main sources is the pollution caused by energy production. By-products produced through industry are another major component of this type of pollution. Besides pollution unique to specific sources, the release of carbon dioxide gas from various industrial sources is a key cause of global warming. The first main source of industrial pollution is the production of electricity. In coal-burning power plants, fly ash is the by-product of burned coal. Once incinerated directly into the atmosphere, most fly ash in the 21st century is either recycled or stored in vast holding ponds.
Various Pollution Control Technologies
The control of the emission of various contaminants into the environment which brings down the level of the pollution is done by various updated methods. The various technologies which control the pollution are laser methods, chemical methods, nanotechnology etc.
The Pollution control equipment can reduce emissions by cleaning exhaust and dirty air. The various control equipment are bag houses or fabric filters, absorbers, electrostatic precipitators, catalytic oxidizers etc.
Human Impact on the Environment
Human applications on various fields may affect the environment which leads to pollution. An increase in population makes excessive demands on natural resources, and increases the demand on agriculture.
Using chemical fertilizers, insecticides and herbicides to increase production pollutes the environment with harmful chemicals. Deforestation causes habitat loss and threatens the survival of species of animals and plants.
Environmental Risk Assessment
An environmental risk assessment (ERA) is a process of predicting whether there may be a risk of adverse effects on the environment caused by a chemical substance. Environmental exposure concentrations of a chemical are predicted and compared to predicted no-effect concentrations for different environmental compartments. Environmental risk assessment is based on comparison of indicators of environmental values over time.
Current conditions are compared against historic “natural” range of variation and predicted future ranges based on differing management scenarios. Assessment of environmental conditions and indicators is summarized in terms of a “risk index.” The assessment and reporting of risk to environmental values can then be used to identify risk reduction strategies. Subsequent revisions to management plans and actions will then hopefully be undertaken to reduce risk.
The increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth. This is a type of greenhouse effect. The most significant greenhouse gas is actually water vapour, not something produced directly by humankind in significant amounts. However, even slight increases in atmospheric levels of carbon dioxide (CO2) can cause a substantial increase in temperature.
Earth’s natural greenhouse effect is critical to supporting life. Human activities, primarily the burning of fossil fuels and clearing of forests, have intensified the natural greenhouse effect, causing global warming.
Sustainability is everything that we need for our survival and well-being against the industrial pollution. Sustainability creates and maintains the conditions under which humans and nature can exists in productive harmony that fulfils the social, economic and other requirements of present and future generations.
At the global scale and in the broadest sense environmental management involves the oceans, freshwater systems, land and atmosphere, but following the sustainability principle of scale it can be equally applied to any ecosystem from a tropical rainforest to a home garden. Sustainability interfaces with economics through the social and ecological consequences of economic activity.
Waste Management Hierarchy
The waste management hierarchy indicates an order of preference for action to reduce and manage waste. The aim of the waste hierarchy is to extract the maximum practical benefits from products and to generate the minimum amount of waste. The proper application of the waste hierarchy can have several benefits. It can help prevent emissions of greenhouse gases, reduces pollutants, save energy, conserves resources, create jobs and stimulate the development of green technologies.
Green computing is the use of computers and related resources in an environmentally responsible manner. This involves the implementation of energy-efficient central processing units (CPUs), servers and peripherals as well as proper disposal of electronic waste (e-waste).
Green computing aims to attain economic viability and improve the way computing devices are used. Green IT practices include the development of environmentally sustainable production practices, energy efficient computers and improved disposal and recycling procedures. Energy use would decline by over 143 billion kilowatt hours per year.CO2 emissions would decrease by 114 million metric tons. That’s like planting 550 million trees! E-waste would be reduced by 7.9 million metric tons.
