According to the British "Financial Times" website reported on November 18, every fall, Hong Kong restaurant will supply a seasonal delicious: crabs. These crabs come from lakes near Suzhou and are shipped to Hong Kong that same day. But food inspectors in Hong Kong have recently discovered a surprising number of hairy crabs shipped this year that contain dangerous levels of carcinogens. Worse still, these crabs appear to come from Taihu Lake - a region that has been a model for China's fight against pollution after years of multi-billion dollar investment.
The Taihu Lake pollution control action failed? Or say something else? Wang Yue, a crab farmer, said the problem was "bathing crabs." Wang Yue and his family kept crabs in shallow water in Taihu Lake. He estimates that the market demand for Taihu crabs is three times as large as he can provide, and foreign crabs are shipped to Taihu for a few days before being sold at high prices - a process known as crab " Bathing. " "Crabs here are delicious because the lake is very good, but people in other cities do not know the difference," says Craig, who makes a lot of money by disguising crab crabs in the field as Taihu crabs.
Reported that Taihu Lake and near the Yangcheng Lake to provide consumers with the best quality crabs. But there are many crabs are kept in other places, which pulled down the price of hairy crabs.
"Bathing crab" seems to be a typical Chinese food safety issue: the growth of hairy crabs surpasses the ability of regulators to check for quality. But the bigger problem is China's environmental pollution. Demonstration of the role of environmental management actions to Taihu Lake water quality has been significantly improved. But the success of this costly solution to China's broader soil pollution crisis and not much effect.
Over the past decade, central planners have developed blueprints to address haze, water pollution, and soil pollution by shutting down or moving factories, controlling emissions, and tightening regulations - the same approach that governs pollution in the Taihu Lake, the report said. The result is a steady improvement in chemical oxygen demand in the water. Chemical oxygen demand is a measure of organic matter in water, an indicator, but also one of Beijing's environmental goals. Dioxin and dioxin-like PCBs found in hairy crabs may come from poorly regulated incinerators or steel sintering plants in the Yangtze River Delta region or elsewhere where "bathing crabs" are kept.
"These pollutants may be emitted in the form of exhaust gases, but if it is present in the crab meat, it is because the pollutants are released into the water and into the soil," says Ma Jun, an environmentalist in China. Persistent organic pollutants (POPs) are difficult to decompose and will remain in the environment for a long time.
Reported that in 2007, Taihu Lake outbreak of a large area of cyanobacteria, resulting in 200 million people were cut off drinking water for several days. After the outbreak of blue-green algae, Beijing ordered in 2012 before the Taihu Lake to clean up. The government closed factories, built sewage treatment plants and prevented farmers from expanding pig farms. Widening the river channel leading to the Yangtze River is also conducive to the Taihu Lake area water cycle. This is not easy. This warm shallow lake is an ideal place for organic contaminants to breed, making it easy to cause algal blooms.
Concentrated efforts to clean up the Taihu Lake at the same time, Beijing is also encouraged to ... ... View Original: http: //www.zgsc123.com/show-109-136956-1.html
