Phytoremediation

I think it is a flagging topic. The method is to clean up the land which is contaminated pollutants by using bioremediation. And now I am eager to discus about phytoremediation that is a part of bioremediation methods.

As I have already told about bioremediation, but not just the microbes and fungi, the plant also can be used to eliminating the chemical waste by the sub-bioremediation called phytoremediation. And the plant will process the chemical waste to change them to be oxygen.

Phytoremediation is a mouthful to say and tough to spell correctly. It is a term that was coined by Dr. Ilya Raskin who was sent as part of the IAEA taskforce to clean up after the Chernobyl Nuclear Power Plant disaster. It is basically, a way to clean soil and groundwater that has been contaminated with radiation or heavy metals by using certain green plants. These green plants extract and contain harmful elements within their ecosystem and thus remove them from the soil and water.

Remember when I had assignment at school about bioremediation, I found an interesting topic about phytoremediation by using a bamboo. In Japan, it’s about 300 km from the Fukushima Power plant, and every day Japanese society sees disturbing images of smoke pouring out of the number 3 and 2 reactors. Japanese society also sees farmers and fishermen complaining about the loss of their livelihoods because of the nuclear disaster. The quicker they can get the reactor under control and start to clear up the better. And they thought about how to clean up the environment from pollution, they used phytoremediation.

After the nuclear disaster hemp was extensively planted around the worst affected areas. Hemp like bamboo grows quickly and helped to reduce levels of iodine, cesium-137, strontium, and plutonium from the soil. Since bamboo grows everywhere in Japan already and requires no inputs of fertilizers and pesticides to flourish, it is the ideal candidate for phytoremediation. And of course, afterwards the bamboo can be used for a whole plethora of purposes. Bamboo represents some advantages versus the traditional water plants such as, the same level of treatment, and lower density for plantation (1 plant/m² instead of 6-11 plants/m²), and also maintain green all the year round, “Phragmites Australls” becomes brown in the winter period and give a bad aspect to the unit during 4-5 months/year, and there’s no competition of other plants when in South Europe, Phragmites Australls can be dominated by other grasses, and the last is a less maintenance.

In conclusion, Phytoremediation employs the use of plants, alone or together with their associated microorganisms, to degrade, contain or stabilize various environmental contaminants in soil, water, and air. Bamboo may be used to decontaminate soil and water by phytoremediation, a natural way of removing pollutants using plants, restoring soil to statutory safe limits.

Bioremediation

We have already known that the environment is contaminated pollution since 2000 until now. The scientists tried to solve the environment problems by using bioremediation methods, why? It is because bioremediation is safe to the environment and humankind, lower cost, and also permanents to environment because it makes the contaminant degraded. Do you that Japan use phytoremediation methods to clean up the nuclear leak? Yes, phytoremediation is a part of bioremediation to clean up the nuclear leak. Phytoremediation method is cleaning up pollution through the use of plants and their microorganisms. In Japan, the scientists have still processed the phytoremediation by using a bamboo. They use this method because it is safe for the environment and can defect the global warming.

The population in this world has increased; therefore it creates more big problems. Like climate change, pollution, mutation, and chemical waste. The problems become worldwide; the estimated number of contaminated sites is significant. It is now widely recognized that contaminated land is a potential threat to human health, and it is continual discovery over recent years has led to international efforts to remedy many of these sites, either as a response to the risk of adverse health of environmental effect caused by contamination to enable the site to be redeveloped for use. One of the methods is to recover the environmental by using bioremediation process.

Bioremediation allows natural processes to clean up harmful chemicals in the environment. Microscopic “bugs” or microbes and fungi that live in soil and groundwater like to eat certain harmful chemical, such as those found in gasoline and oil spills. When microbes completely digest these chemicals, they change them into water and harmless gases such as carbon dioxide. 

The good idea is to use bioremediation to treat the environment which is contaminated with pollutants. Why? Because it is made a promising approach, such as, it would permanence, it is because contaminant was degraded, and it had potentially low cost, 60-90% less than other technologies.

SETI

Do you know what SETI is? I think ever body has already known about it. Yes, SETI  is from the initial letters of “the Search for ExtraTerrestrial Intelligence”, SETI is the science by using telescope, radio, and optical to find the signals from alien civilizations on the skies.

The idea of SETI began from the publication of a paper in the British journal Nature by Giuseppe Cocconi and Philip Morrison in 1959. The paper discussed about the possibility of the existence of alien civilizations and how we might be able to detect them. And their conclusion was radio waves that easiest method to detect alien civilizations. Why the scientists chose radio waves to detect signals from other civilizations? It was because radio waves were able to travel the massive distances between stars. Radio waves could be produced with rational amounts of power.

In the 30 years since the early Ozma which was conducted in 1960 by Frank Drake, many other have been carried out for more responsive equipment, overmuch longer time frames, observing the thousands of stars. No further there’re no signals from alien civilizations which had been detected, but the scientist had not to stop giving up, they had begun to scratch the surface. They have known that there’re many skies and frequencies that signals could be received on. Lately, the scientists at the University of California at Berkeley have tied together the internet to attack this problem.

Rose

Rose in family Rosacea, is herb with thorny stem. In history, rose or “queen of flower” was a symbol of life of religion. Rose was from China, middle-east, and east-Europe. But now we can see roses in our own country. Roses amended and spread vastly in other countries especially in country which has subtropical and tropical season. Rose has many varieties in color, from white to crimson and has high productivity, it’s about 120-280 buds/m²/year. That’s why we can find roses easily.

Calyx, leaf, and root of rose contain polyphenol. And its leaf contains saponin and tannin, whereas the root contains saponin and flavonoid.

The calyx has known as a cough medicine. Just take three calyxes, and put it all in stew pan and pour with a glass of hot water, after that drink it up.

Roses actually have aura and high energy. Immerse in bath up full of rose calyxes can rise somebody’s feelings especially into good mood.

Study from New England journal of medicine found that someone has diabetes that immerses in warm water with rose calyxes in 30 minutes can reduce the blood sugar as much

Study from Japan found that immerses in warm water during 10 minutes is good for health especially for heart. It can also smooth the blood stream, and reduce pain and stress.
