China existing chemicals

The Chemical Registration Center of the State Environmental Protection Administration (CRC-SEPA, later the Chemical Registration Center of the Ministry of Environmental Protection, MEP) began to inventory existing chemical substances manufactured in or imported into the People s Republic of China in 1992. The first edition of the Inventory of Existing Chemical Substances in China (lECSC) included chemical substances that were manufactured, processed, or used inside China, or imported from outside China for commercial purposes during the period from January 1, 1992 to December 31, 1994 [124]. CRC-SEPA stated the purpose of the inventory as follows [124, p. 3] ... 

The "Inventory of Existing Chemical Substances in China" is a technical supjportive document for laws and regulations on the prevention and control of pollution caused by chemical substances. 

In summary, the manufacture of new chemicals in China has only been regulated since 2003. Approximately 45,000 substances were listed as existing chemicals before the 2003 Provisions began chemical controls. The MEP accepted 217 notifications for new chemicals under Order Number 17 between 2004 and 2010, and 148 Typical Notifications under Order Number 7 from 2011 to 2013. 

Approximately 45,000 chemicals were listed on the lECSC when the Provisions on the Environmental Administration of New Chemical Substances (SEPA Order Number 17) came into effect in 2003. China banned or restricted some of those existing chemicals based on international conventions and regulated the import/export and use of certain hazardous chemicals.

In the United States, CAS number 88-73-3, Benzene, l-chloro-2-nitro-, is listed on the Toxic Substances Control Act (TSCA) Non-Confidential Inventory with no Significant New Use Rule (SNUR) [38]. It has been designated as a High Production Volume (HPV) chemical [39]. In the European Union (EU), ONCB has been notified under REACH as an intermediate and as a chemical produced or imported at 100-1,000 tormes per armum. The REACH notifications refer to use as an intermediate in closed processes, and to use as a laboratory reagent [40]. In China, ONCB is listed on the Inventory of Existing Chemical Substances Produced or Imported in China (lESC) it is also listed in the Catalog of Hazardous Chemicals [41]. 

In contrast to the lengthy regulatory history in the United States and the European Union, the story of 1,4-DCB under chemical control regulations in China is quite brief. 1,4-DCB is listed as an existing chemical substance in China. It is also considered to be a hazardous chemical [76]. 

In China, polymers are generally considered to be of low concern and most existing polymers are not regulated [166]. Polyethylene (CAS 9002-88-4) is on the lECSC [41] as an existing chemical.

The use of chemicals to produce heat, light, smoke, noise, and motion has existed for several thousand years, originating most likely in China or India. India has been cited as a particularly good possibility due to the natural deposits of saltpeter (potassium nitrate, KNO3) found there [11-... 

Se has a greatly uneven distribution in the world. For example, there are Se-deficient places with the Keshan disease due to scant Se intake in Keshan (China) while by contrast, in other places of China, the levels of Se concentration are toxic to humans and animals. The Se accumulation and distribution in plants hence varies among species, and as a function of chemical forms and concentrations of Se supplied. In general, with an elemental abundance of 0.08 J,g g in the Earth s crust and 13 4g g in the Earth s interior, the existence and speciation of Se in nature is so dispersive that it commonly does not reach a threshold abundance warranting industrial... 

In principle, these figures can be neglected for a worldwide consideration. However, taking into account that today s supply originates from a small number of bigger mines besides a large number of smaller ones (especially in China), and that only 10-20 chemical converting plants exist, it is evident that local problems exist or may arise in the future. 

Propylene oxide (PO) is a versatile chemical intermediate used in a wide range of industrial and commercial products. Current world production is over 6 million metric torts a year. While several processes exist, the Shell Chemicals companies have derived a strong competitive advantage by using and continually developing their proprietary styrene monomer propylene oxide (SMPO) technology, a process in which propylene and ethylbenzene (EB) are converted into PO and styrene monomer (SM), respectively. Worldwide, there are now five world-scale SMPO plants based on Shell technology, the most recent one started up in 2006 in China.
