Huge pipeline accidents cause spills, kill dozens in China

Huge pipeline accidents cause spills, kill dozens in China

This is what Qingdao normally looks like.

Pipeline accidents in China during the past week have killed more than 50 people, led to the arrests of nine officials, caused two large oil spills, and triggered evacuations. Both of the ruptured pipelines were owned by China’s largest oil refiner, China Petroleum, also known as Sinopec. Here are the basics:

Leak and explosion on Friday

A pipeline ruptured in the eastern port city of Qingdao, causing crude to gush into streets and into the sea. Several hours later, with cleanup underway, the crude exploded, igniting a street filled with shops and apartments. The latest confirmed death toll is 55 people, with nine still missing and 136 reported injured. Oil dispersants are being sprayed over an oil spill stretching from Jiaozhou Bay into the Yellow Sea. The government blamed human error. On Tuesday, the AP reported that seven company officials and two Qingdao city employees were in custody.

Leak on Tuesday

On the other side of the country, in Anshun City in the southwestern Guizhou province, a crane toppled over on Tuesday at a high-speed railway construction site, splitting open a pipeline used to transport gasoline. Residents within a mile of the accident were evacuated and the Press Trust of India is reporting that an estimated 2,200 tons of gasoline has spilled. A team of 110 people is working to repair the pipe and mop up the toxic fuel.

WTF is going on?

A fossil-fueled energy boom feeding China’s economic growth is what’s going on.

“The ever-growing refining capacity and oil infrastructure in China had certainly seen a rising number of incidents,” Andrey Kryuchenkov, an analyst at VTB Capital in London, told Bloomberg. “The Sinopec pipeline explosion will surely see a prolonged investigation and a safety review.”

China’s Massive Algae Bloom Could Leave the Ocean’s Water Lifeless

It’s become an annual affair, the rafts of green algae washing up on the shores of Qingdao, China. Since 2007, massive algae blooms in the Yellow Sea have been fueled, scientists think, by “pollution and increased seaweed farming” south of Qingdao. The mats of photosynthetic phytoplankton aren’t dangerous to people (unless you count ruining a day at the beach as dangerous), but the return of these massive algae blooms year after year could be troubling for the marine creatures living in the Yellow Sea.

“The carpet on the surface can dramatically change the ecology of the environment beneath it,” says the Guardian. “It blocks sunlight from entering the ocean and sucks oxygen from the water suffocating marine life.”

Vast blooms of algae can cause the water to become “hypoxic,” to have the concentration of oxygen in the water drawn down so low that it makes it uninhabitable for many marine creatures. A strong case of hypoxia can further lead to something called a “dead zone.” And, by drawing down the oxygen levels and messing with the chemistry of the water, algae blooms can temporarily amplify ocean acidification. The National Oceanic and Atmospheric Administration explains how algae blooms lead to dead zones:

Such recurring, annual algae blooms like the one in Qingdao aren’t limited to China’s Yellow Sea, either. According to Scientific American, there are at least 405 dead zones around the world. One of the worst in the world is the one in the Gulf of Mexico, where this year researchers with NOAA expect around 8,000 square miles of the Gulf to be oxygen depleted—a patch of ocean about the size of New Jersey, says National Geographic. If the bloom lives up to expectations, this year’s would be the largest dead zone in the Gulf on record.

So while China’s algae problem may be making a mess for swimmers, it’s the life beneath the waves that may be hurting the most.
