The Effect Of Heavy Metals On Groundwater

As the exploration of the industrial development and increased speed of the urban sprawl in Beijing, many severe environmental issues attribute mainly to the anthropocentric activities have been come out of the scene. One of them is the air pollution. Air pollution has been regarded as the most severe environment issue in China since it has already threatened to physical health, especially for the respiratory tract and lung. “In January 2013, Beijing experienced historical heavy air pollution. In this particular month, very few days were observed with blue sky.” (Lijian Han et.al., 2015) According to the analysis of the driving factors, “the population grew fast, and energy consumption and the number of vehicles increased rapidly” (Ju Zhang et.al., 2010), these factors add together can make the air quality worse than any one of them separately can. Firstly, it has been an undoubted truth that more and more people originally lived in rural has been moved to core urban of Beijing since there are more opportunities in there. Therefore, the huge explosion of urban population with more energy release and more CO2 exhalation is seen as an inevitably primary factor causing the bad air quality. What’s more, as the population

There are three main mechanisms by which the chemical composition of groundwater, which is our natural source of drinking water, may be changed: by natural processes, by man's waste-disposal practices such as those for sanitary wastes, liquid industrial wastes, solid wastes, and radioactive wastes, and by spills, leaks, and agricultural activities and other sources unrelated to disposal. The degree of risk posed by contaminants varies according to many factors. These include the volume and toxicity of the contaminant, its concentration in the aquifer, its persistence in the environment, and the degree of human and environmental exposure to the contaminant. In addition, the number of persons affected, or likely to be affected, over time and the percentage of available groundwater both locally and regionally should be taken into consideration. If the contaminants in the groundwater exceed the standards set for drinking water by the federal government, for example, then the water is hazardous for the use for which it was designated under the standards. These standards include, however, only a limited number of chemicals, and thus they do not necessarily protect humans or the environment against either the short-term or the long-term effects of every contaminant that might be found in

Groundwater pollution is a major problem that is growing in all over the world. Of course the united states America also facing this problem. People of Mississippi State are worried about groundwater pollution due to the several human activities. Groundwater is a main source of their water supply. Disposal of solid waste in landfills is an economic option for many municipalities in developing countries where alternatives like incineration and composting are costly. However, groundwater pollution from the leachate generated within the landfill and migrating through the bottom liner material into the underlying groundwater aquifers remains a major public health concern I studied chemical parameters of groundwater in Alcorn State University as a part of my project.

Experiments were done on the water quality and the contamination of groundwater. First, I observed the effects that different pollutants had on groundwater. I predicted that the experiments with the oil and vinegar would create the most contaminations to the water. When the laundry detergent were mixed with the groundwater, it created a light green color with a pleasant smell. The second water treatment experiment were about filtering techniques to remove contaminants from water. I predicted to drain the water by removing all the contaminants

Groundwater contamination has many far reaching environmental, political, societal and economic effects. Groundwater contamination, while obviously potentially detrimental to human wellbeing, can have a large impact on localities in any region of the world. When toxic agents are introduced into a groundwater system it puts all local wildlife in immediate danger. This includes the health of both flora and fauna near or in the flow from the source of contamination. Human health can also be impacted by this type of contamination. Toxic agents, in my example specifically tetrachloroethene (PCE), have many harmful effects on human health including affecting the central nervous system, causing cancers and causing pulmonary edema (Tetrachloroethylene Toxicity, 2017).

It is always difficult to remove contaminations from soils because it contains many toxic chemicals such as (Pb, As, Cu, Cd, Cr, Ni, Hg and Zn). This chemicals mixed with the soil after burning of industrial waste, electronics waste or uses of agricultural technology. Then rain water makes it seep deep into the soil and cause soil pollution. This makes it so difficult and time consuming to remove, particularly when the affected area is on a large scale. Soil is made of by two components which are organic and inorganic solid constituent, water and mixture of different gasses present in various proportions. The mineral component in the soil varies, according to the parent material which the soils had been developed due to the issue of different type of climate conditions. Also, soil can also be classified into three different properties, physical, chemical and biological properties. Physical properties of soil are being controlled by soil water movement, such as texture and soil structures. The soil moisture have high tendency in controlling solute movement, salt solubility, chemical reaction and microbiological activities and most importantly the bioavailability of metal ions. In this situation, a successful phytoremediation program must be considered as an alternative in the specific site. In the past lots of researchers have tried different method in order to mitigate or reclaim the heavy metals polluted soils, but so far phytoremediation is the best of all because it is

Groundwater pollution occurs when pollutants get into the water under the ground.You should not drink if it is polluted. Animals should also not consume it. Some of the pollution comes from the air. A lot of the pollutants comes from chemicals and nuclear waste

All around the world, countries are fighting to keep their drinking water clean. Whether it’s streams, rivers, or lakes, countries have taken great measures to maintain high quality drinking water for both human consumption and animal consumption. Countries must first understand the sources of the polltion, then determine the best methods to eliminate the pollution. Clean drinking water is a valuable resource and a the key to human survival. Plants and animals also depend on water for their growth, so all water must be kept clean. The major contributors to water pollution can be classified in three categories, industrial, agricultural and municipal.

Human activities could have important implications of air pollution in Beijing. Initially, some Chinese traditions are responsible for the problem. The celebration of Lantern Festival with fire works and firecrackers is one of the best examples. According to Wang et.al. (2007), some primary and secondary components such as Ba, K, Sr, Pb, Mg were over five times higher than in the normal days during the lantern festival in 2006 and these components are the significant part of the air pollution. Urbanisation of Beijing, in addition, is a vital reason of the problem. As urbanisation progressing, more factories were built and ran, some of which emitted poison gases and polluted the air. What makes matter worse, urbanisation also increase the usage of vehicles in Beijing and lots of components which can polluted air due to the burning of fossil fuels. Further more, other human activities including land clearing for

Ground water forms a large percent of all the used water on the earth. And as it cannot be seen, it is usually overlooked or ignore when considering all the water on the earth. Since aquifer is valuable source, protecting it form pollution and managing its use carefully will guarantee its future as an important part of eco-system and human activity. Recently, industrial applications of toxic heavy metals have caused dangerous environmental problems. This essay will show the effect of aquifer polluted by some contaminants such as Cr (III), Fe(III), Cu(II), Cd(II), and Pb(II) or radioactive materials on people, plants and animals. In addition, it will demonstrate the best treatment and preventative methods. Furthermore, it will argue that the pretreatment of industrial wastes is the best way to prevent the pollution in ground water.

To sum up, groundwater contamination can be related to waste disposal, land disposal of solid waste, and brine disposal from the petroleum industry. Over 50% of the United States population depends on ground water for drinking water. Water management needs to be in place to regulate what is going in water and where waste can be put to prevent contamination. Contamination of groundwater and population of surface water with waste are big problems affecting water supply. The problem associated with water pollution has the ability to disrupt life on our planet to a great

When there is an addition of undesired substances from human activities in the groundwater, it can cause groundwater contamination. There are many industrial operations that cause contamination in ground water, due to the large quantities of chemicals used. Chlorinated hydrocarbons, which are used in cleaning products and solutions containing chromium, which are used in metal plating, lead to the groundwater contamination. These industrial wastes are dumped in storage tanks and they leak, thus causing contamination.

Deprivation of accepted resources is perhaps one of the lethal lapses mankind has ever prepared in its voyage of progress and civilization. All the natural resources are contaminated with lethal lapses. Among them the land and water resources are worst affected and under continuous stress with both biotic and abiotic, due to anthropogenic interventions. If we talk about the soul of infinite life i.e., SOIL then it seems to appear the primary recipient by design or accident of a myriad of waste products and chemicals used in modern society. Soil contamination can be defined as the, addition of any substance to soil that may exert adverse effects on its functioning and capacity to yield a crop. Contamination of heavy metal is of special worry

Chemical elements can cause harmful effects on human health due to the use of plants that are grown in contaminated soil. Through bioaccumulation, over plants that absorb an element from the soil, elements enter into the food chain and shall be deposited in the human body. Root system in plants plays an important role in the distribution of elements from the soil through the plant. Elevated pH values can affect the lack of accessible forms of specific nutritious elements. The value of pH has a decisive influence on the dynamics of all the elements in the soil, especially micro elements and heavy metals. In the acidic environment the solubility of metals increases, they cross to the solution of the soil from which the plant adopted them, which can lead to greater adoption of these elements by plants. The increase in soil acidity reduces the amount of plant available phosphorus, which by binding to iron and aluminum becomes difficult soluble phosphates (Resulović, Čustović 2002) Also, there is a more intensive adoption of manganese and its toxic effects on

There is an array of pollutants capable of contaminating freshwater in different ways (Schiedek et al., 2007). Some of these contaminants include fertilizers and pesticides from agriculture farms, heavy metals such as mercury which are prone to long-range transport and oil spills from pipes in the course of transport of fossil fuels (Kundu et al., 2007). Human activities have also been identified as the most prominent cause of freshwater contamination (Liu et al., 2004). Some of these human activities include improper management of agricultural runoff and sewage disposal methods and the use of energy sources that can emit particulates into the atmosphere, which may eventually end up in freshwater bodies (Li et al., 1999). Approximately 50% of untreated waste water is dumped in freshwater bodies. The consumption of contaminated water may cause illnesses such as cholera and
