The properties of persistent organic pollutants and mercury 1. Persistence to chemical and biological exposure 2. Bioaccumulation and bioconcentration 3. Poor solubility in water, solubility in the fat tissues 4. Volatility, transboundary transfer 5. Toxicity: reproductive, neuro- and immune toxicity, canceriginity
Human health effects of e-waste lung cancer and chronic

Potential value of raw materials in waste in 2016
Others - 5% black metals - 3% Стекло и glass and ceramics - 20% керамика – 20% Plastic - 40% Non-ferrous metals - 32% If every one user of mobile phone utilizes Если бы каждый пользователь мобильного телефона утилизировал всего один телефон , вместе мы бы сэкономили около 240 000 тонн сырья . one phone all together we would economy 240 000 tons of raw
Nokia has conducted a research in 13 countries (Finland, Germany, Italy, Russia, Sweden, Great Britain, United Arab Emirates, USA, Nigeria, India, China, Indonesia and Brazil), in which 6,500 people took part. 3% - sent their old cell phones for utilization 4% - threw out the old devices to the landfill 15% - gave to relatives 16% - sold 44% - kept them at home 74% never thought about recycling the phone
The total weight of all mobile phones produced in the world is tens of thousands of tons per year, and tens of thousands more tons are accessories.
Only a few high-tech companies around the world can extract gold 1 ton of gold ore and other expensive 0,3- 5 g of pure gold materials from their phones, as this process is truly dangerous and 280 g of pure can lead to poisoning. gold 140 g of Platinum 1 ton of cell phone 140 g of Copper
