1. What is RoHS?
- Directive on the restriction of hazardous substances in electrical and electronic equipment and the RoHS Directive (Restriction of hazardous substances electrical and electronic equipment directive print 2002/95 / EC, hereinafter referred to as RoHS) by the European Union through through to February 2003.
- This law was implemented starting July 1, 2006 and are required to be enforced and become law in each Member State. All the products that contain one of 06 substances are not sold in Europe.
- This directive restricts the use of six hazardous substances in manufacturing all kinds of electrical and electronic devices are lead (Pb) <1000 ppm, cadmim (Cd) <100 ppm, mercury (Hg) <1000 ppm, hexavalent chromium (Cr6 +) <1000 ppm, polybrominated biphenyls (PBB) <1000 ppm, and polybrominated diphenyl ethers (PBDE) <1000 ppm.
2. The harmful effects of toxic elements
Can see these are harmful elements unique to the human body. Here are a few typical damage of these elements:
- Lead (Pb): Lead is toxic to the central nervous system, peripheral nervous system, effects on enzyme systems containing hydrogen group activities. People with lead poisoning will be disturbed parts hematopoietic (bone marrow). Depending on the severity of poisoning may have abdominal pain, joint pain, inflammation of the kidneys, high blood pressure, brain seizures, severe poisoning can be fatal. Features after entering the body, lead less weeded that accumulate over time and then poisoning.
- Mercury (Hg): Mercury has the ability to react with sulfur-containing amino acids, the hemoglobin, albumin; have the ability to link the membrane, alter potassium, acid base balance changes of the tissues, causing energy shortages provide neurons. Children with mercury poisoning will be schizophrenia, seizures, not proactive.
- Cadmium (Cd): - Cadmium enters the body by the kidneys and bone accumulation; jamming activity of some enzymes, which causes increased blood pressure, lung cancer, nasal septum perforation, making renal dysfunction, bone marrow destroyed, affecting the endocrine, blood, heart.
- Chromium (Cr): cause stomach ulcers, intestines, hepatitis, nephritis, lung cancer.
3. The electrical and electronic equipment in the regulation of this Directive are divided into 10 groups:
- Large household appliances (such as refrigerators, washing machines, microwaves),
- Small household appliances (eg vacuum cleaners, oven)
- IT equipment and telecommunications equipment,
- Consumer equipment (radios, televisions, musical instruments),
- Electrical, electronic instruments,
- medical devices,
- automatic processing machine,
- Lighting equipment,
- observation instruments and controls.
