Basic Concepts Of Phytoremediation Environmental Sciences Essay

Basic Concepts Of Phytoremediation Environmental Sciences Essay Contamination of soil in oil refinery has been an environmental issue of modern industrialization in many countries. The main reason for this contamination is the contaminated products generated during the activities associated with purifying and refining petroleum in oil refinery. Those activities including distillation, chemical treatment, product transfer and storage and so on are the contributors of the contaminants. These consist of the petroleum hydrocarbons, asbestos, metals, some inorganic compounds and etc[1]. There are a lot of effective remediation technologies such as pump-and-treat (PAT), soil washing, thermal desorption, bioremediation and etc. However, some of them are causing inhibition of soil fertility or even destruction to ecosystem. Therefore, this encourages my evaluation on phytoremediation- a variation of bioremediation which has been an emerging technology for remediation of petroleum hydrocarbons since late 1990s[2]. Phytoremediation is a cost-effective in-situ treatment which uses up vegetation to clean up the petroleum-contaminated soils and groundwater. In general, it is to utilize the ability of the special plants roots associated bacteria to take up, accumulate, and breakdown the contaminants (e.g. TPHs) located in soils and ground water[3](Figure1). This technology is more suitable for: (a) large sites with shallow contaminants where only polishing treatment is required; and (b) the sites where vegetation is used as a final cap and closure of the site[4]. Figure 1 Basic concepts of phytoremediation 2. Mechanisms There are seven mechanisms of phytoremediation: phytoextraction, rhizofiltration, phytovolatilization, phytostabilization phytodegradation, hydraulic control and rhizodegradation. They can be described as follows: Phytoextraction This is also known as phytoaccumulation. It aims to utilize plant roots in order to uptake and translocate the metal contaminants in the soil into the above ground portions of the plants[5]. The plants absorb, concentrate, and precipitate the toxic metals from the soils into shoots, leaves, etc. (Fig. 1)[6]. Figure 2 Phytoextraction of Ni from contaminated soil There are some plants, called hyper-accumulators, which are capable of accumulating extremely large amount of metals especially nickel, zinc and copper[7]. These plants need to be either incinerated or composted to recycle the metal after have been used for some time[5]. Rhizofiltration It is the adsorption or precipitation onto plant root surfaces, or absorption into contaminants which present in the soil solution in the root zone. Although rhizofiltration looks similar with phytoextraction, the main function of rhizofiltration is to remediate the contaminated groundwater rather than the soil by removing inorganics and metals. The plants are first raised in greenhouses with their roots in water until a large root system has been completed. At this stage, the original water source is replaced by contaminated for acclimatization. Once the saturation of contaminants in the roots has been reached, the plants are harvested. In the study of removal ability, sunflower, Indian mustard, tobacco, corn and etc. have been used to investigate the removal of lead from water. Among those plants, sunflower has the greatest ability[5, 6]. Phytovolatilization This involves the uptake and transpiration of contaminants by plants, with release of the contaminants in vapour form to the atmosphere. It looks like a natural air-stripping pump system. This natural ability of volatilization enables the plants to volatilize the volatile organic compounds in parts of refinery site, vinyl chloride as well as inorganics and etc[6, 8]. Phytostabilization This process is to use plants for immobilizing contaminants in the soil and groundwater. The roots absorb and accumulate the contaminants, provide adsorption or precipitation within the rhizosphere (root zone) in order to reduce the mobility of contaminants. As contaminant migration to the groundwater or air has been minimized, the bioavailability for their entry into the food chain can be lowered. Metal-tolerant species can be used to restore vegetation to those metal-contaminated sites. Those species not only can decrease the potential migration of contaminants but also prevent the leaching of contaminants to groundwater[5]. Phytodegradation This is also called phytotransformation. It is the breakdown of contaminants through metabolic processes or the effect of constituents (e.g. enzymes) produced by the plants. The complex organic contaminants are degraded into simple molecules and these molecules are then incorporated into plant tissues[5]. Hydraulic Control Hydraulic control is employed by plant canopies on the control of water table and the soil field capacity. Phreatophytic trees and plants are commonly used due to the ability to transpire large amount of water and thereby influence the water balance at the site. The increased transpiration decreases the tendency of contaminants to move towards groundwater water or alleviates the migration of contaminants from the site in groundwater plumes[6]. There is something to be noted that trees must be rooted into a shallow water table aquifer in order to successfully prevent plume migration[9]. Rhizodegradation This is often referred to as phytostimulation or planted-assisted bioremediation/degradation. It can be achieved by breaking down the contaminants in the soil within the rhizosphere through microbial activities. During the microbial activities, organic contaminants such as fuels and solvents can be biodegraded by microorganisms into harmless products. The nutrients for the microorganisms are provided by the exudates produced by the plant[5]. 3. Major influencing factors (a) Soil composition and quality: Soils with high concentration of contaminants soils tends to have a poor physical conditioning which is not able to promote the growth of vegetation and rhizosphere microorganisms. Common limitations are the deficiencies in moisture-holding capacity, aeration, nutrient and permeability and so on. Thus, adjustments are required to improve the quality of soil before planting. A common adjustment is the amendment on pH of soil by adding sulphur or lime[9]. (b) Selection of plant: Plants are selected by taking the concerns of the target contaminants to be polluted and the remedial objectives for redevelopment such as time frame and risk management. Moreover, the climate for the plants to be adapted into is also very important. The ability of the plant acclimating to the soil and the depth of plants root structure also cannot be neglected. The selection and use of plant species must be done carefully in order to avoid the introduction of non-native species into the areas which are new to that species[10]. 4. Advantages Relatively low cost: Comparing with other treatment technologies such as thermal treatment, chemical extraction, some ex-situ technologies and so on, phytoremediation is relatively inexpensive as it only uses plants. [5, 11]. Besides, there is no extraction cost as it is an in-situ treatment. Safe and passive: Phytoremediation is driven by solar energy and there is no chemical usage Feasible for large varieties of contaminants: It can be used on the major contaminants produced in oil refinery-petroleum hydrocarbon as well as the other minor contaminants such as VOCs, TCE and even heavy metals and etc[12]. Mitigation of soil erosion: The establishment of vegetation can effectively improve the soil structure and resulting in reducing the soil erosion. Preventing migration of contaminants: Phytoremediation avoids excavation and transport of polluted media as the contaminants are destroyed in place. Therefore, it can lower the risk of spreading the contamination[13]. Aesthetically pleasing: The use of green plants can contribute a more eye-pleasing and natural green environment. 5. Disadvantages Relatively shallow clean-up of soil with low contaminant concentration: Treatment is limited to soils less than 1 m from surface for grasses, less than 3 m for shrubs, less than 6 m for deep-rooting trees and groundwater less than 3 m from the surface. Besides, it is not effective for contaminated site with high concentration [5, 14]. Slow process: The whole process is relatively slow compared with other technologies as three to five growing seasons are needed to achieve remediation goals[5]. Site specific and critical plant selection: The optimization of plant growth and the contaminants uptake depends on the characteristics of the site and the plant species that are selected[5]. Potential food chain contamination: Contaminants may enter the food chain through animals which eat the plants or borne fruits[14]. Production of residual waste: Using phytoremediation may relocate contaminants from the subsurface to the plant, thereby creating residual waste to be disposed of[5]. By looking at the features of phytoremediation in various aspects, we may find some drawbacks and limitations. Although the overall performance of phytoremediation is still not effective as soil vapor extraction and other technologies, its trade-off such as low cost, practicality and environmental-friendliness indicates that it can be a promising solution for remediation in oil refinery, especially in developing countries. Also, many studies on phytoremediation are still being carried out, so it can certainly be combined with a lot of technologies for future improvement and ultimately be widely applied in oil refineries all over the world.

Sarnath Lion Capitol

Anna H. Asian Art History Maurya Dynasty: Sarnath Lion Capital Mauryan Empire of India lasted from 4th to 2nd century BCE. According to Coomaraswmy, an Indian historian, Mauryan art had three phases. The third phase was considered the beginning of brick and stone sculpture and architecture. The pillars of Asoka would consider such example, which are free standing carved animal capitals created in the time of Asoka empire. There are 20 known pillars that Asoka commissioned. These pillars are made out of shafts of sandstone and display Buddhist symbols. Asoka had a sculpture of four lions placed on top of one of his pillars, knows as Sarnath Lion Capital. These lions were portrayed as power and still remain a national symbol of India. The art elements portrayed in this sculpture define the meaning and characteristics that had important significance during Mauryan dynasty. The Sarnath Pillar’s composition has more abstract relation than schematic portrayal. The capital contains four lions, standing back to back, mounted on an abacus with a frieze carrying sculptures of an elephant, horse, bull, and a lion. In this way, four rivers of India is represented. The animals are separated by elapsing wheels, which symbolizes time. Because wheels are also mentioned in Buddhist religion, it can be explained as spiritual purpose as well. Since the sculpture has a schematic relation, it is hard to understand the main point at the first sight. The sculpture is volumetric with few high relieves. The animals and wheels can be considered as high relief where as the lion’s top portion would consider three dimensional. Overall sculpture itself is considered as free standing, since it can be iewed from all angles. The proportional relationship to the size of animals in reality is more abstract than realistic. The animals at the bottom portion of the sculpture, are much smaller than in real life. Although the lions can be considered realistic, despite the overlapping of one another. The adherence from reality suggests that the size of lions portrayed in large scale signifies power, besides of their nature meaning (powerful animal of animal kingdom). In this way it leads the viewer to concentrate more on lions than on other parts of the culpture. The lines of the sculpture let the eye to lead to the main ideas and it emphasizes more volume than lines. Some parts of the sculpture, such as water plant, and lion’s beard have curvilinear orientation where as the wheel is more rectilinear. The lines help to create more naturalistic details, which effects the sculpture to be more easily defined. The texture of the sculpture is smooth, more similar to copper made. This deviates from the real texture of the objects depicted, even though it gives the rich shiny feeling hich is more similar to lion’s natural color. Because the lack of color it give the sculpture more abstract than naturalistic look. The absence of the color gives more dull look and less definable. It also suggests that the painting techniques during Mauryan dynasty was not well developed and had limited us e of techniques. Asoka's pillars are some of India's earliest major stone sculptures. The Asoka's reign were highly religious. He was the first powerful monarch to practice Buddhism, therefore his sculptures were mainly on Buddhism and power.

Analysis Of A Raisin In The Sun By Lorraine Hansberry

Welcome to Windham High School’s very own theater production of the incredible play A Raisin in the Sun, written by Lorraine Hansberry. To further understand the play please read the text below about the background of Hansberry’s life, living conditions in the era that the play took place, and reviews written about the play. Lorraine Hansberry was a playwright and a writer. She was born in Chicago May 19, 1930 in Chicago, and she grew up in the Woodlawn neighborhood in the South side of Chicago. Her parents were well known civil rights activists; Carl Hansberry (her father) and Nannie Hansberry (her mother). When she was 8 years old, she and her family moved into a white neighborhood, where they experienced violence and antagonism†¦show more content†¦Even though people of color had more freedom in Chicago than those who lived more in the South, they still struggled to find their place living there; they lived in their own communities away from whites with very few opportunities to make lives for themselves. Living conditions weren’t very ideal. In an excerpt from How We Built the Ghettos James Boulie has written, â€Å"Many blacks lived in apartments that lacked plumbing, with only one bathroom for each floor.† In the play A Raisin in the Sun, Mama and her family shared their bathroom with neighbors and they had a system for who would use the bathroom at certain times. Boulie has also written, â€Å"With the buildings so overcrowded, building inspections and garbage collection were below the minimum mandatory requirements for healthy sanitation. This unhealthiness increased the threat of disease.† This is most likely why mama had always been cleaning and taking care of the home they lived in. Not only were the living conditions awful, but the opportunities to move into nicer places were even worse. In the History of African Americans in Chicago, on Wikipedia, it was written that, â€Å"Redlining is the practice of denying key services (like home loans and insurance ) or increasing their costs for residents in a defined geographical area.† When it came to a colored person trying to move into a white neighborhood, it usually didn’t end very well.

A Raisin in the Sun provided a twist in the American art as it highlighted on key issues which were unfolding in the U.S in the 1950s. Despite the economic boom experienced after World War II, there was growing racial tension and domestic tension. Summary The play A Raisin in the Sun is worthwhile discussing as it cut across sensitive topics†¦show more content†¦The play further focuses on the American dream through the character Walter who has a desire to make progress and is full of entrepreneurial spirit. Mama: What done got into you girl? Walter Lee done finally sold you on investing? (Hansberry 19). Walter doesnt challenge the current system but instead works very hard to ensure that he rises to the highest social class. He yearns of having a nice car, an expansive house and expensive jewelry for his wife together with a nice job. Walters dream envisages the American dream which at that time was the main focus. The play also addresses feminist questions which were prevalent during this period. Hansberry uses the character Beneath, who is socially progressive and studies to become a doctor to show that marriage is not an important rite of passage and women should focus on other career goals. Hansberry also delves into th e issue of abortion through the character Ruth. Ruth who came from a poor background becomes pregnant thus complicating the family situation which seems unable to accommodate another life thus prompting her to abort. This makes the topic to enter into action in an age where abortion was illegal. Style Hansberry was very objective in her work; as through her distinct work from other plays of that time drives a message home to the audience. Thus, in my opinion, the story is enlightened to individuals not only during the era it was set but even in the recent timesShow MoreRelatedAnalysis Of A Raisin In The Sun By Lorraine Hansberry1856 Words   |  8 Pages11, 1959 Lorraine Hansberry Was African American Born in Chicago on May 19, 1930 Died at age 34 from pancreatic cancer She attended the University of Wisconsin and was the first person in her family to not attend a black college She worked as a waitress and cashier at first, and writing was just a hobby.
