Environmental Pollution And Its Effects

Pollution is one of the biggest global killers, affecting nearly 100 million people. Pollution comes in many different forms and affects the world and the environment in many different ways. Along with the best known pollutants such as water, air, and land, there are other pollutants that many people do not know much about. These include light, noise, thermal, and household pollution and are all just as damaging as the most known ones. Pollution is an introduction of a harmful or poisonous substance into the environment that has a negative effect on life around it. Pollution is deadly, and it is destroying the only world suitable for life. Pollution is a

Pollution is one of the most concerning topics to talk about in today's modern world. It acts as a poison for anything that lives and breathes; it could toxify water, air, land, humans, and animals, and is not to be taken lightly.

No matter how hard we try, the effects of pollution are everywhere. From major catastrophes like the

Bioremediation is the process in which microorganisms such as bacteria, yeasts, molds, and filamentous fungi are introduced into the spills. The introduction of these microorganisms assists in altering and metabolizing various chemical compounds present in oil. When the microorganisms metabolize these certain compounds it significantly reduces the time it takes for the oil biodegradation to occur.

Another common remediation technique is stabilization or solidification which aims to alter the contaminants into a less soluble or mobile form (Wuana and Okieimen, 2011; Mulligan, Yong, and Gibbs, 2001; United States Environmental Protection Agency, 1991). In both methods water and a site-specific chemical solution is mixed into the soil to either alter its physical - make it less soluble - or chemical - reduce mobility - properties to make it less likely that the contaminants will move into other locations or be inhaled (Wuana and Okieimen, 2011; Mulligan, Yong, and Gibbs, 2001). Chemical treatment can also fall under the umbrella term of stabilization. Chemical treatment is add chemical solutions to the soil to detoxify the soil and can be used as a pre-treatment for other techniques such as solidification (Wuana and Okieimen, 2011; Mulligan, Yong, and Gibbs, 2001). These techniques are typically preferred due to lower costs but other physical elements of the soil, such as boulders, can make mixing the soil difficult and the process can volatilize and release volatile compounds (Mulligan, Yong, and Gibbs, 2001; United States Environmental Protection Agency, 1991). Mobility of contaminants can also be reduced by using the technique of vitrification through the process of heating up the soil (Wuana and Okieimen, 2011; United States Environmental Protection Agency, 1991). This method results

The study conducted by McKew et al. examined the efficiency of degradation of n-alkanes (or straight-chain hydrocarbons) in response to various types of intervention strategies. It is somewhat established that the native marine bacteria may not be able to degrade the constituents of crude oil spills without the aid of microorganisms that are specialized in disintegrating hydrocarbons – Hydocarbonoclastic bacteria, or HCBs. McKew et al.’s study quantifies this

With the rapid expansion of cities and the incredible growth of technologies, humans have polluted the atmosphere, acidified the oceans and ruined the soils worldwide. This has ultimately caused drastic changes in the environment that affects all creatures that inhabit the planet. Furthermore, modern transportation systems across the world are resulting in dangerously high emissions of carbon monoxide, nitrogen dioxide and greenhouse gases such as carbon dioxide into the Earth’s atmosphere on a daily basis. Also, industrial production is emitting sulfur dioxide, lead and other air pollutants at the same rate. With no signs of slowing down, toxins will sustain their presence in the air and ultimately continue to be absorbed by the world’s oceans. So even though the atmosphere is losing some of those gases, however, they are simply just being replaced by daily habits. Meanwhile, the oceans are becoming more acidic in the process. In fact, the

Pollution has had a shocking impact in the atmosphere for including many irreparable damages to ocean life, serious health issues to human beings, and negative changes to the environment. Pollution is a man-made global dilemma which is increasing to a serious magnitude. Human beings, the number one culprit, seem to be blind to this matter. Humans’ inability to clearly see the problem they are creating, will be one of the causes for the world to be no more.

Does Bleach Eliminate Bacteria? Abstract There are many methods used to destroy bacteria and this experiment tests the affects of Clorox bleach on bacteria. It will outline the methods used to determine if bleach could, or should be, used to decrease the amount of bacteria and whether or not this particular method is effective. The experiment will also test whether the levels of phosphorus and phosphatase in the soil are affected.

Fruitvale was a perfect town. There was a nice creek (Strawberry Creek) that dogs and children could play in and a very good diner that families could eat out at. Fruitvale was a mini fairy-tale land, until they hit reality. Fruitvale was recently contaminated by a No-Bug Pesticide that farmers had been using to get rid of the bugs eating their crops. Twelve wells were tested and the No-Bug Pesticide had not contaminated the Fruitvale Municipal Water Well yet. After one year, we tested all of the wells again to see how far the contaminant has spread. We have found that Fruitvale has approximately three years to get Fruitvale de-contaminated. We want to keep the cost at a minimum and all of the Fruitvale residents safe. To meet these goals, we hypothesize that bioremediation would be the most efficient way to accomplish the following task of making Fruitvale a safe

Sewage treatment, or domestic wastewater treatment, is the process of removing contaminants from wastewater and household sewage, both runoff (effluents) and domestic. It includes physical, chemical, and biological processes to remove physical, chemical and biological contaminants. Its objective is to produce an environmentally-safe fluid waste stream (or treated effluent) and a solid waste (or treated sludge) suitable for disposal or reuse (usually as farm fertilizer). Using advanced technology it is now possible to re-use sewage effluent for drinking water, although

Urban and rural areas need bioremediation because they have different problems. Some uses of bioremediation include cleaning up crude oil, gasoline, pesticides, and sewage. In 2010, a massive oil spill had taken place in the Gulf of Mexico which had been a massive hazard to the animals and even the humans. Cleaning up the oil was risky for humans, so the idea of using bioremediators came up. Also, TNT and other explosives can be broken down when plants are are engineered to contain certain bacterial enzymes.

Pollution has become a prevalent issue worldwide and has begun to affect the air used to breathe, the soil used to grow food, and the water used to drink. All of these effects result in commonly occurring destruction of health and wildlife that one may have seen on the news or heard from peers. In order to live, one needs food, water, clothing, and shelter. If the water and food that society consumes gets contaminated, a major component of life has been eradicated, which can only have negative consequences. If more people are educated as to what effects the environment, the world has a chance to counteract the effects of pollution. The main causes of pollution are the burning of fossil fuels such as with car exhausts, littering as a result of societal norms and laziness, and factory waste as a result of lax waste regulation, and can result in mass destruction of the environment and catastrophic effects on the everyday lives of contemporary people.

The contaminated sites are directly treated using the microorganisms. Underground petroleum pipes sometimes have leakages. Such sites of contamination are directly treated with microorganisms that can degrade petroleum hydrocarbons. The same is applicable in case of oil spills and heavy metal contamination. Phytoremediation is brought about by certain special plants which can take up the pollutants and make them less available in the soil. Some examples of such plants are mustard, alpine pennycress, hemp and pigweed. When the soil which is to be treated with the microorganisms is stimulated by providing it with oxygen, it is known as bioventing. Bioleaching is a process where living organisms or microorganisms are used to extract metals from their respective ores. This process ensures that there is not much expenditure of both chemicals and energy to bring about the extraction. Land farming refers to amending the soil with organic amendments like vermicompost, bulking agents etc which are tilled into

Bioreactors are employed when the value of the gold recovery is sufficient to justify the costs of installing and operating the necessary equipment. Bioreactors are able to process less gold ore at one time, but create a much faster oxidation process. This process usually utilizes higher grade ores compared to heap leaching. This type of bioleaching is characterized by a reactor tank in which relatively finely ground ore and nutrients are added, as well as bacteria containing solution to create a slurry (Figure 1). This mixture is then mechanically or air agitated.
