Is well known that certain industrial chemicals can affect the hormone system and cause endocrine disorders. So far, hundreds of chemical substances will affect the endocrine system. glue stick The majority of such chemicals or aromatic phenolic compounds.
In recent years, the reproductive system damage in the community and discussed the concern that damage to the reproductive system will be produced in the animal world and nature, and epidemic diseases on the rise, including testicular cancer, genital abnormalities, sperm quantity and quality changes even a serious impact on "overall environmental hormones." Endocrine effects of these organisms will lead and its compounds,glue gun even in low concentration, stage of development on the sensitive environment, it will affect other substances into the environment, the same endocrine effect will be transferred to other substances.
Study showed that the two chemicals affect the endocrine - nonylphenol and phthalates in the industrial chemicals were used, and the annual production in the Federal Republic of Germany more than 100 tons. Phthalates PVC plastics used for software, the NP is usually present in the phenolic resin, mainly in the form of nonylphenol ethoxylate surfactants as a phenolic resin. On the other hand, polycyclic aromatic hydrocarbons (PAHs) is considered to be contaminants in the manufacturing process, in such as power tools, paint and plastics found in consumer products.
Import and export volume of these three substances is enormous, both as raw materials or semi-finished or finished products. Impact of these three chemicals are endocrine aromatic compounds: polycyclic aromatic hydrocarbons (PAHs) for the benzene derivatives, nonylphenol (NP) for the phenol derivatives, phthalate esters of benzene dicarboxylic .
The presence of such substances and toxicity caused by high level of public attention, the German authorities to implement strict control on this.
Famous German journal published a series of social concern on the health impact of consumer goods. In 2005, the company's power tools as a black plastic handle unpleasant odors released who were sued, after testing, found to contain nearly 2,000 mg of high levels of polycyclic aromatic hydrocarbons (PAHs). Reported the same year, Halloween masks found in high concentrations of phthalates and nonylphenol (NP). This year, the disclosure of a paper folding stroller found in a large number of polycyclic aromatic hydrocarbons (PAhs), plasticizers and organic tin compounds. The chemicals are the major phenolic and aromatic substances, scientific evidence of its health consequences. In particular, nonylphenol, inhibits the growth and maturation of the endocrine system.
a) nonylphenol.
Nonylphenol (NP) is a member of alkylphenols, due to its lubricating properties, mainly for the production of detergents and surfactants.
In 2003, the European Directive 2003/53/EC requires all member states formally promulgated and enforced, including Germany from January 2005 began formal implementation. Instructions to NP "as a finished product or raw material, its concentration is equal to or greater than 0.1% shall not be sold or used in the market", that is, the maximum allowable limit of 1000 mg / kg.
b) phthalate.
Phthalates are 1,2 - benzene dicarboxylic two aryl alkyl or alkyl ester, mainly used as plasticizers or plastic additives [mainly polyvinyl chloride (PVC)], in order to increase the flexibility of plastic. Plastic materials in PVCs material found in a variety of applications, including medical pipes, blood bags, shoes, stationery, sheet flooring and wallpaper, wire cable insulation, cover and toys.
Germany, the EU Directive on the restriction of phthalates 2005/84/EC (76/769/EEC Directive 22 modified version of) the way through secondary changes in the laws, into their daily necessities, and Cosmetic Act (May 30, 2006 ), in the June 9, 2006 announcement (BGBl2006, Part1, nr.
26). For each or the sum of several phthalates in the maximum allowable limit of 0.1%,
Toys and infant products.
Phthalate (2 - ethylhexyl) phthalate (DEHP) 117-81-7.
Dibutyl phthalate (DBP) 84-74-2.
Phenyl-butyl phthalate (BBP) 85-68-7.
Can be put into the mouth of toys and infant products.
Isononyl phthalate ester (DINP) 28553-12-0and68515-48-0.
Isodecyl phthalate ester (DIDP) 26761-40-0and68515-49-1.
Dioctyl phthalate (DNOP) 117-84-0.
c) polycyclic aromatic hydrocarbons.
Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous chemicals, polycyclic aromatic hydrocarbons of this series covers more than 100 kinds of compounds are potentially carcinogenic substance found in crude oil, creosote, coal tar and coal and other natural substances. Polycyclic aromatic hydrocarbons through the formation of incomplete combustion, pyrolysis process will produce the oil, mainly used in manufacturing pharmaceuticals, dyes, plastics (PVC toys, software), pesticides, rubber (tool handles and trim products), and paint. Such substances that can accumulate in the environment, low solubility in water is usually not easily burn.
In 2005, the German based (LFGB) section 30 of the PAHs can be allowed to develop for the limit value, and that harmful substances can not exist in consumer products.
By August 2, 2005 Berlin meeting, the experts recommend the use of the materials used for the final consumer PAHs maximum allowed value, in Table 2. PAH components of the test method detection limit to be met for 0.1 mg / kg.
Parameters and skin contact time is not more than 30 seconds in contact with skin for more than 30 seconds.
Benzo (a) pyrene (mg / kg) 201.
The sum of 16 PAHs (EPA) (mg / kg) 20010.
If the electrical and electronic products exported to Germany, ZentralstellederL? Nderf? RSicherheitstechnik (ZLS) in Gepr? FteSicherheit (GS) certification requirements of the PAHs is mandatory. Toys, food, baby products and product may be placed in the mouth of the PAH requirements in Table 3.
Parameter Category 1.
And food contact materials or pursuant to law may be placed in the mouth of the definition of Category 2 material.
Category 1 is not within the scope of toy materials.
Benzo (a) pyrene (mg / kg) was not found (<0.1) 1.
