It has been two months since the explosion in Binhai District of Tianjin on August 12. Overwhelming reports from different media have calmed down, and the clean-up work in the core area of the disaster has been finished, with large tracts of land exposed. It is reported that the core area of the explosion will be used to build a park in two months. These 24 hectares of land will be used to build a harbor ecological park to restore the damaged environment. However, to those who experienced this blast, the huge sound is still clear and the pain is not vague off. Besides, traffic disruption, mistrust to environment and doubt caused by the explosion put the hazardous chemicals industry on the table of public judgment. The current situation and abuses in administration hiding in the industry will be discovered.
Hot hazardous chemicals industry
Hazardous chemical industry has grew rapidly in recent years. Data released by National Bureau of Statistics shows that sulfuric acid, caustic soda, soda ash and synthetic ammonia produced in 2014 in China are respectively 88.46 million tons, 30.59 million tons, 25.14 million tons, and 57.45 million tons (2013). These four chemical products are included in the hazardous chemicals of conventional industry. The amount of hazardous chemicals by road transportation each year is more than 300 million tons, accounting for over 30% of the total freight, and the rate is increasing each year. With rapid development these years, the production of major hazardous chemicals of China all rank the first place. Hazardous chemicals included in "Hazardous Chemicals Directory (2015)" has 2828 in number, which are all essential raw materials in petrochemical industry, pharmaceutical industry and cosmetic industry.
According to the statistics from chemicals industry association, China is second only to America in terms of hazardous chemicals production and application. With the attraction of over 40% of profit, various domestic districts try to introduce hazardous chemicals industry. Till now, more than 200 national and provincial large-scale industrial parks have been built, and more than 300, 000 hazardous chemicals companies have been founded. The annual output of hazardous chemicals each year will be over 1.8 billion tons.
Only sodium cyanide’s annual output can reach 300, 000 tons, and 250, 000 tons is used in the country, most of which serve as "gold washing liquid" to extract gold. As an important chemical raw material, sodium cyanide is widely used in the fields of chemical synthesis, electroplating, metallurgy, organic synthesis of pharmaceuticals, pesticides, and metal processing. Its most "attractiveness" is in the ability of extracting gold. China Association of Renewable Resource and Recycling Deputy Secretary-General Tang Aijun said to NetEase that using sodium cyanide to extract golf from e-waste has become an important industry. He further added that regular enterprises have stopped using sodium cyanide to extract gold, while its usage in irregular enterprises is prevalent. Although gold extraction needs a huge amount of sodium cyanide, different from foreign countries’ harsh regulatory which will lead to high cost, extensive usage for being lack of regulatory in China still can make relevant industries get generous benefits. China Gold News reported that, a large-scale gold producer in Inner Mongolia in 2014 needed to use more than 2000 tons of sodium cyanide each month to extract only 5.1 tons of gold.
