THE LOVE CANAL BY FAZIRA AMIRA


Quite simply, Love Canal is one of the most terrible environmental tragedies in American history. But that's not the most worrying fact. What is poorer is that it cannot be regarded as an isolated event. It could happen again anywhere in this country unless we move expeditiously to prevent it. It is a cruel irony that Love Canal was originally meant to be a dream community. That vision belonged to the man for whom the three-block tract of land on the eastern edge of Niagara Falls, New York, was named William T. Love. Love felt that by digging a short canal between the upper and lower Niagara Rivers, power could be produced cheaply to fuel the industry and homes of his would be model city. But despite considerable backing, Love's project was unable to tolerate the one-two punch of fluctuations in the economy and Nikola Tesla's discovery of how to economically transmit electricity over great distances by means of an alternating current. By 1910, the dream was devastated. All that was left to commemorate Love's hope was a half ditch where construction of the canal had begun.

In the 1920s the seeds of a genuine nightmare were planted. The canal was turned into a municipal and industrial chemical dumpsite. Landfills can of course be an environmentally acceptable method of dangerous waste disposal, assuming they are properly sited, managed, and regulated. Love Canal will always remain a perfect historical example of how not to run such an operation.

 

In 1953, the Hooker Chemical Company, then the owners and operators of the property, covered the canal with earth and sold it to the city for one dollar. It was a bad buy.

 

In the late '50s, about 100 homes and a school were built at the site. Perhaps it wasn't William T. Love's model city, but it was a solid, working class community.

JILIN CHEMICAL PLANT EXPLOSION BY FAZIRA AMIRA

The Jilin chemical plant explosion were a series of explosion which occurred on 13 November 2005, in the No.101 Petrochemical Plant in Jilin City, Jilin Province, China, over the period of an hour. The explosions killed six, injured dozens and caused the evacuation of tens of thousands of residents.

BACKGROUND INFORMATION
The No.101 Jilin Chemical plant was located in Jilin City in Jilin Province, China around 380 kilometers up river from Harbin City. The plant was located next to the Songhua River, which is the main water source for much of northeastern China, including Jilin and Harbin. The Songhua River eventually runs into the Amur RIver which flows through southern Russia.
The Jilin Chemical Plant itself was the first major, large scale chemical industry base to be built in China, producing chemicals such as benzene. nitrobenzene, and aniline which are often used in the production of different plastics.


EXPLOSION
The initial explosion happened on November 13, 2005. Around noon on the day of the blast a blockage occurred in the chemical plant’s processing nitration tower for the the production of benzene. A plant worker attempted to clear the blockage on his own, but was unsuccessful.3 The blockage and the workers inability to clear the blockage eventually lead to an explosion at 1:40 p.m.

The plants initial explosion was so powerful that they shattered windows that were at least 100 to 200 meters way from the chemical plants. Explosions continued throughout the plant for about and hour and eventually lead to a large scale fire at the plants. The fire was eventually put out in the early morning of November 14,6 by around three hundred firefighters.

After the blast and the resulting fire was put out at the chemical plant, Jilin Petrochemicals denied that the Songhua River has been polluted by spilled chemical from the plant. The local Jilin officials also claimed that as a result of the explosions and resulting fire had not released any toxic chemicals into the air, but that the fire had burned all the chemicals and that it had only produced carbon dioxide and water.2

There were initial worries that the explosion may have been caused by a terrorist groups, but it was later discovered that the explosion was not caused by terrorists and instead was operator error.



EVACUATION
After the explosion and resulting fire the residents of Jilin City did evacuate the city, not because they were warned to by the local government, but because they discovered what the actual situation of the chemical explosion was. Soon after the explosion occurred a large amount of yellow and dark smoke filled the sky around the city, the smoke made it extremely difficult for the residents to breathe. By 4 p.m. almost everyone that was able to met at the cities center and began leaving the city. But because the police blocked off city streets for emergency vehicles like cars, taxi,and buses were unable to make there way through the city and greatly reduced the evacuation. Initially more then 30,000 residents of the city evacuated the city along with 12,000 university students, including 5,000 students form the Jilin Petrochemical College. But because residents were unable to use vehicles, large amount of the old and sick were left behind. Eventually 10,000 more residents had to be evacuated by the Chinese Government.

Shortly after the explosion and during the cities evacuation, electricity, water, heat, and all telecommunications were shout off, except for radio broadcasting. In the city all schools and business were closed and by 7pm [that not almost no one had electricity. The communication that was being sent out by the Chinese government suggested that the city was safe and that only non-toxic carbon dioxide had been generated by the incident, despite the fact the sky above the city was still largely covered in thick yellow smoke.

DEEPWATER HORIZON OIL SPILL BY MUHAMAD AFIG

In the wake of the explosion of the Deepwater Horizon offshore drilling rig in the Gulf of Mexico on 20 April 2010. Federal agencies, state and local government agencies, and responsible parties faced an unprecedented challenge. An oil discharge continued for 87 days, resulting in the largest ever oil spill in United State waters. 11 workers are dead in this disaster.

Area of oil spill






                                                          
Oil spill of this size was estimated at approximately 206 million gallons (4.9 million barrels) are occurred in United State waters.The incident tested the public and private response capabilities, as well as the legal framework of liability and compensation under the Oil Pollution Act. The oil spill cleanup, Natural Resource Damage Assessment (NRDA), and compensation processes continue today.

Oil Spill Response Activities


The uncontrolled discharge from the Deepwater Horizon continued for approximately 87 days until, following several attempts, responders gained control of the release on July 15, 2010. The response involved multiple agencies. During the height of operations in the summer of 2010, response personnel levels reached 47,000, and response vessel numbers approached 7,000;4 and  the maximum extent of shoreline oiling involved almost 1,100 miles of shoreline.

Cleanup

On 15 April 2014, BP claimed that cleanup along the coast was substantially complete, but the United States Coast Guard responded that a lot of work remained. The details of the cleanup operations are unclear.The State of Louisiana was funded by BP to do regular testing of fish, shellfish, water, and sand. Initial testing regularly showed detectible levels of Dioctyl sodium sulfosuccinate, a chemical used in the clean up. Testing over the past year reported by GulfSource.org  for the pollutants tested have not produced results.

BAIA MARE CYANIDE SPILL BY MUHAMMAD HAZIQ


Occur in January 2000,the Baia Mare cyanide spill was a leak of cyanide near Baia Mare, Romania into the Somes river by the gold mining company, Aurul, a joint venture of the Australian company Esmeralda Exploration and the Romanian goverment.The polluted waters eventually spread and reached the Tisza, poisoning the river of Tisza and then the Danube, killing a large number of fish in Hungary and Yugoslavia. the spill has been called the worst environmental disaster in Europe since the Chernobyl disaster, Russia in 1986.

Sasar river in Baia Mare



Background


Aurul company claimed that it had the ability to clean up a by-product of gold mining, the toxic tailings which began to be spread as toxic dust by the wind. Promising to deal with them and to extract remaining gold from them via gold cyanidation, the company shipped its waste product  to a dam near Bozinta Mare, Maramures county. if you wonder about gold cyanidation, gold cyanidation is a technique of extracting gold from low-grade ore by converting a gold into water soluble complex and what happened next triggered the beginning of disaster. on the night of January 30, 2000, a dam holding contaminated waters burst and 100,000 cubic metres of cyanide-contaminated waters spilled over some farmland and then into  the Somes river. Esmeralda Exploration blamed excessive snowfall for the dam failure as the spill was actually the result of poor dam design and unusual weather conditions.
Tisza river in Hungary

Effects
After the spill, The Somes had cyanide concentrations of 700 times above the permitted levels. The Somes flows into the Tisza, Hungary's second largest river, which then flows into the Danube, Europe's second longest river, located in Central and Eastern Europe. After the cyanide entered the Danube, the large volume of river's water diluted the cyanide but in some sections it still remain as high as 20 to 50 times the maximum permitted concentration. In addition to cyanide, heavy metals were also washed  into the river and had a long-lasting  negative impact  on the environment. The spill contaminated  the drinking supplies of over 2.5 million  Hungarians. More than 1,400 tons of fish have died as a result of this devastating environmental accident that destroyed the life basis and necessity for hundred of fishermen along the Tisza  in Hungary. Large quantities of fish died  due to  the toxicity of cyanide in the waters of the river. Living organisms such as foxes and osprey also need to pay the price as they died after eating contaminated fish.


Recovery

Two years after the spill, the ecosystem began to recover, but it was still far from better at that  time  as the fishermen  of Hungary claimed that their catches in 2002  were only  at a fifth of their original levels. The Aurul company, now known as Transgold restarted the operation some month after the accident. Though Transgold has improved its safety standard and precautions, it still under heavy criticism  of environmentalists because  the company  still choose cyanide in its gold mining operation. As there have been no additional accident in recent years, the river of Tisza could slowly recover back to its initial state.Today, the number of fish is close  to the number before the accident, but there are still fewer species in Tisza river. 

The legacy of the Baia Mare cyanide spill is a strong reminder on the importance of environmentally safe gold mining techniques environmental care, for sure.We hope this post can enlighten all of you about the importance of environmental care.
