Hi Readers, This time Informasi Ahli will discuss about Environmental Science.
Environmental science is the study of interdisciplinary integrating biological and physical sciences (including chemistry, physics, biology, soil science, geography and geology) to study the environment and solutions regarding environmental problems.
Environmental science study of the environment and environmental engineering. Environmental science using social science to understand human relations, policy and perception of the environment. Environmental engineering focused on technology and design in order to improve the quality of the environment.
Work environmental scientists is to understand the process of the Earth, pendalian mitigation and pollution, evaluating alternative energy systems, natural resource management and the impact caused by global climate change. Environmental issues almost always include physical interactions, biological and chemical processes. In analyzing environmental problems, environmental scientists use the system approach. An effective environmental scientists have the ability to relate to space and time, as well as the use of quantitative analysis in environmental analysis.
Environmental science came alive as a substantive, active field of scientific investigation in the 1960s and 1970s driven by :
1. To analyze the environmental problems that required complex multi-disciplinary approach.
2. Protocol investigation is required by the specific environment of substantive environmental law, and
3. To address environmental concerns needed awareness of the public.
atmospheric sciences focused solely on studying the Earth’s atmosphere, by an emphasis on linkages to other systems. Atmospheric sciences learn about meteorology, atmospheric dispersion modeling of airborne contaminants, the phenomenon of the greenhouse gas, sound propagation phenomena related to noise pollution, as well as light pollution.
An example of the phenomenon of global warming, physicists created a computer model of the transmission of infra-red radiation and atmospheric circulation, biologists analyzing the contribution of animals and plants for flux Carbon dioxide, chemists examine atmospheric chemicals and their reactions, and oceanographers and meteorologists analyze the dynamics of the atmosphere.
An interdisciplinary analysis of ecological systems that are affected by one or more stressors may include several related environmental science fields. Example: Someone check the setting of the estuary in the construction industry that could affect certain species contained in the water and in the air as a result of air pollution. In this study, the chemists would analyze the transport of water pollutants to the marsh, biologists will describe the fauna and flora, physicists calculate the emissions of pollutants Urada and geologists analyze marshland and bay muds.
Environmental chemistry is the science of the chemical changes in the environment. Environmental chemistry include water pollution and water pollution. Topics that environmental chemical analyzes on the chemical degradation of the environment, multi-phase transport of chemicals (for example, evaporation of solvent containing lake to yield solvent as an air pollutant), and chemical effects that occur in biota.
For example studies, case solvent tank leaked into the soil habitat of threatened amphibian species. The computer models will be used as a method to understand or cope with the level of contamination of soil and surface transport under solvent.
The chemists will characterize the molecular bonds of solvent with certain soil types, while biologists studying the effects that occur in soil arthropods, plants and organisms that are present in the pond which is the food of the endangered amphibian.
Geoscience included in the geological sciences environment, environmental soil science, volcanic phenomena and evolution of the earth’s crust. In some classification systems may include hydrology, including oceanography.
For example the study of soil erosion, the analysis calculation is made of the surface runoff by soil scientists. The Geomorphologists fluvial participate in petrified examine sediment transport in overland flow. Scientists fission duty to assess the changes in light transmission. Biologists who analyze subsequent impacts to aquatic fauna and flora of the increase in turbidity.
In the U.S. the National Environmental Policy Act (NEPA) of 1969 establishes requirements in analyzing large projects in terms of specific environmental criteria. State laws have been widely apply the principle of local-scale action. The results of this application is an explosion of documentation and studies on environmental impact before the fact tidakan development.
By reading the examples of environmental impact statements, it can check the specifications of environmental sciences prepared under NEPA such as:
“Waste water treatment for consumption expansion to San Diego/Tijuana Estuary, the construction of the Houston, San Francisco International Airport Expansion, metro transport system and the construction of interstate 66 through Arlington, Virginia.”
In England and Wales, the Environment Agency (EA) which was formed in 1996 is a public body that improve and protect the environment and make the rules on public listed dala local government sites, (previously a deputy prime minister’s office). The Environment Agency was established under the laws of the environment in 1995 as an independent body and cooperate with the United pemmerintah in enforcing regulations.
In common usage, ecology and environmental science are used interchangeably, but technically only refers to the study of the ecology of the organism and interaction with the environment. Ecology is considered as part of an environmental science that can involve health problems or general chemically pure. In practice, there is overlap between the work of ecologists and other environmental scientists.
Academic programs in environmental science is defined by the following The National Centre for Education Statistics in the United States :
“A program that focuses on the application of chemical, biological and principles of physics in studying the physical environment and provide solutions to environmental problems, control of environmental pollution and degradation, Interactions between the natural environment and human beings, and management of natural resources including instruction in chemistry, geosciences, physics, biology, statistics, climatology and mathematical modeling.”
