< p > > a > < < /a > >, the EU non food quick warning system (RAPEX) has issued a consumer warning to four children's shoes exported to France and Spain by China. The reason is that children's shoes contain "six valent chromium" exceeding the standard. One of the children's shoes exceeds the standard of 100ppm, which is 33 times that of France, Spain and other countries. The above four children's shoes have been ordered to withdraw from the market by the above four children's shoes. < /p >
< p > "six valence chromium" is recognized as a carcinogenic high toxic substance. It is easy to be absorbed by human body. Skin contact may lead to allergy and has lasting danger to the environment. The sources of "six valent chromium" in leather production are mainly two aspects: first, the "six valent chromium" may be produced in tanning process of leather making industry; two, the "six valent chromium" may be contained in tannery materials, especially additives. < /p >
< p > < a > href= > http://sjfzxm.com/news/index_s.asp > > /a > March 26th. The European Commission amended the annex 17 of the REACH regulations, limiting the six valent chromium (VI) content of imported leather products to 3ppm, or three parts per million. The new regulation will take effect in May 1, 2015. Prior to this, only Germany in the European Union had banned the six valence chromium content of clothing, watch bands, bags, chairs, sofa, neck bags and leather toys, which were not more than 3ppm, while the other EU Member States currently control the demand of six valent chromium at 1000ppm, and the difference between the two was more than 333 times. What is more concerned is that in the 2014 edition of the eco textile standard Oeko-Tex100, the requirement of six valent chromium for Eco textiles is <0.5ppm, and the limit of heavy metal chromium in leather products is 10ppm. < /p >
It is necessary to pay attention to the differences between different importing countries in terms of the "six valence chromium" limit, especially in Germany, France, Italy, Spain and other countries. The two is to control the source, strengthen supplier management, do not arbitrarily purchase raw materials from non qualified suppliers, make clear the quality assurance provisions, carry out six valent chromium test on chrome powder used for tanning, three control production process, adjust tanning technology, such as using plant retanning agents, use reductive neutralization reagents and retanning agents, use antioxidants as fatliquoring aids when leather fatliquoring, so as to ensure that there is no excess six < a > valence chromium < /a > during the production process of 3ppm. < p > for this reason, the inspection and quarantine department reminds the relevant enterprises: 1. < /p >
