Six trapped in Russian mine

Six Russian miners are trapped underground after a cave-in at their pit in the Siberian region of Kemerovo.

When the incident occurred, 17 people were working underground in the Lenin mine, but 11 of them escaped to safety.

A rescue operation was underway. "It is very hard work indeed. Rescue workers can use only their hands, because machinery can provoke a new cave-in," she told Reuters by telephone from the regional capital of Kemerovo, also known as the centre of the giant Kuzbass coal basin.

"The mishap occurred at a depth of 400 metres. If need be, the rescue operation will continue through the night."

Accidents are not uncommon in Russian coal mines, many of them caused by outdated equipment or neglect of safety rules.

A methane gas explosion killed 110 miners at the Ulyanovskaya mine in March last year, becoming Russia's deadliest mine accident since the fall of the Soviet Union.

Two months later, a methane gas blast killed 38 people at a neighbouring mine, Yubileynaya, operated by the same company.

Read the statements and say if they are true or false.

1.Eleven miners were injured to death during the incident.

2.The rescue team used machinery to help the miners.

3.The tragedy happened at a depth less than 500 metres.

4.Such accidents often occur because of outdated equipment.

5.The cause of gas explosion at the Ulyanovskay mine was chlorine.

Computer Waste Impacts in Asia Alastair Iles

Electronic wastes are a rapidly growing transnational problem. Electronic wastes result when consumer, business, and household devices, including computers, refrigerators, fax machines, cell phones, software, and home entertainment systems, become obsolete and are disposed of or sent for recycling. The billionth computer worldwide was sold at some point in early 2003, with tens of millions already in storage. Much of this waste is traded from industrial nations to developing countries. In 2002 alone, the US exported up to 10.2 million obsolete computers (or around 50-80% of all PCs sent for recycling in the US) to Asia, most of them to China. The problem is not just industrial countries exporting computers to developing countries. Within China alone, 5 million computers may already be obsolete because of the economy's rapid growth over the past decade. Electronic wastes contain up to 1000 toxic substances, ranging from lead, chromium, to plastic additives. Dumping or recycling can lead to these substances contaminating ecosystems and human bodies, and to adverse health outcomes. Electronic wastes exemplify the pattern of technology and materials flows in the contemporary...
