to be disposed of. Cleaning up contamination: Phytoremediation is a novel, efficient, environmentally friendly, low-cost technology, which uses plants and trees to clean up soil and water contaminated with heavy metals and/or organic contaminants such as solvents, crude oil, polyaromatic hydrocarbons and other toxic compounds from contaminated environments. This technology is useful for soil and water remediation. Mechanisms: Phytoremediation uses one basic concept: the plant takes the pollutant
Phytoremediation: Using Plants To Combat a Stressed Environment Plants have long been adapting the traits necessary to survive in a wide variety of stressful environments – including areas of high salinity, extreme heat, drought, and freezing temperatures - but now, using genetic modification, scientists have been able to expand the role that plants play in the environment. With the advent of transgenic biotechnology, plants can be enhanced with qualities that not only allow them to flourish
REMEDIATION OF CONTAMINATED MARSH LAND: Introduction: Coastal wetlands are commonly known as marshes or marsh land. There are various kinds of marsh land from coastal to inland and saltwater to fresh water etc but mainly distinguished as Tidal marsh lands, Freshwater marsh lands, Mangrove swamps or brackish wetland (Mitsch and Gosselink, 2000). Wetland ecosystems are herbaceous vegetations that not only protect wide variety of wildlife but also protect the shores support coastal fisheries also (US
question my group was trying to test was, does a variation in solution affect the growth or production of duckweed? Duck weeds are one type of plant that has the ability to eliminate nitrogen and phosphate out of fresh water. This is called phytoremediation (Bunnell 84). Since humans use other organism to clean up environmental contamination, we would call this bioremediation. Duckweed can also be used as a natural wastewater system treatment method, which is ideal for developing countries (Nhapi
In the first semester of college, I was enrolled in a flex dedicated to Biology majors and Kinesiology. So we all had something in common. The concept that I learned most was that humans actually induce pollution themselves. This year we were able to go on a field trip to a location in Los Angeles where there was an oil drill that contaminated the air and everything around it and the residents of the area were blind to it. This then made me want to dig deeper into which ways we pollute our environment
Soil remediation is part of a broader effort known as environmental remediation. It restores previously contaminated land to an uncontaminated state and is an important part of sustainable development, especially in respect of resource management and reducing reliance on landfill (Scottish Environment Protection Agency, n.d., p. 4). Most countries around the world are actively engaged in some form of soil remediation. Each year in the European Union, several billion euros are expended on the remediation
woodlands trials on seepage from TSFs; and approximately 200 plant species will be used out of the almost 600 species found to grow naturally on the reef outcrops, polluted soils and tailings. The final phase of research (2009-2012) will look at how phytoremediation plants might be able to produce materials such as precious wood, fibres, chemicals, essential oils, dyes, gums, and recoverable minerals and metals for secondary industries, and thus help local communities.
Bioremediation is the technique of using living organisms to clean up contamination in land and water is called bioremediation. A subset of bioremediation is phytoremediation (technique of using plants as environmental clean-up remedies. petroleum industry employs bacteria to clean up after oil spills and leaks have occurred. oil-loving bacteria break down the chemicals into natural substances, including carbon dioxide gas, a type of alcohol, and water. Bioremediation, while safe relies on natural
Pesticides and Fertilizer run off from farms causes an overwhelming negative effects on the environment. Pesticides contaminate the water and poison fish both killing them and causing biological magnification in the fish that are higher up in the food chain. When humans eat these fish the risk of being harmed by pesticides is increased. Tobacco plants were engineered to express a gene that detoxifies 2,4-dichlorophenoxyacetate ( 2,4-D), one of the most commonly used pesticides world wide, and removes
The various activities of human beings affect adversely all environments where the plants, the animals and the humans live (Kaya et al., 2002). The numbers of chemicals which are the most important group of environmental pollution were limited to a few thousand until the beginning of this century and the majority part of that was constituted by plants, animals and mineral origin accounted for natural ingredients. The production of the chemicals which were 7 million tons in 1950 is estimated to reach
environmental commons, which at the moment are suffering as some stakeholders take more than they give. Sustainability also hinges on environmental stewardship of ecosystems, and reclamation of contaminated sites using environmental services such as phytoremediation and mycoremediation. Grey water recycling from homes and businesses reduces fresh water usage, and can be used to irrigate urban agriculture projects, such as green roofs, green walls, community gardens, and edible forest gardens which in turn
Bioaccumulation is the slow process of increasing chemical content in a living organism over time. This happens either because the chemical is taken up faster than it can be used. It is also because the chemical cannot be broken down for use by the organism. Compounds that are harmful to health, such as mercury, can accumulate in living tissues of organism. Contamination with mercury is a good example of the bioaccumulation process. Usually, mercury is taken up by phytoplankton and bacteria. Small
2.1 NANOTECHNOLOGY: Many main technological innovations in the 21st century is expected to be based on nanotechnology (Mukunthan et al., 2011). It is a rapidly growing multidisciplinary field which includes many branches of science like physics, chemical engineering, super molecular chemistry, mechanical engineering, material sciences, biotechnology and medicine (Dondaa et al., 2013). Bio nanotechnology integrates biotechnology and nanotechnology for developing biosynthetic and environmental-friendly
Heavy Metal Pollution By/Diar Alrubayee Pollution is one of the most ignored concepts in the modern world. It is a topic that often gets forgotten by talk of conservation, sustainability, climate change and energy issue, perhaps, because it is a complex subject with lots of sources and lots of effects. In spite of the fact, that pollution is one of the biggest global killers. At the same time, it can be solved in our life time, and the solutions are relatively low-cost. There are some major substances
The environment, and particularly the aquatic environment, has been focused within in the last years due to the large amount of released chemicals. Thousands of synthetic chemical compounds are currently recorded for use in industry and agriculture, and thousands of tons of these are produced yearly. In addition, several tons of more unintended byproducts produced with these synthetic compounds. Regardless of the source or original intended use, fundamental amounts of these chemicals end up in the
