2. E-waste
Equipment that mainly uses current and electromagnetic fields is called electronic equipment; Waste electronic equipment belongs to electronic waste.
E-waste mainly includes household appliances such as refrigerators, air conditioners, washing machines and televisions, and communication electronic products such as computers. Electronic waste is commonly known as "electronic waste".
There are many kinds of electronic waste, which can be roughly divided into two categories: one is waste electronic products with relatively simple materials and less harm to the environment, such as refrigerators, washing machines, air conditioners and other household appliances, as well as medical and scientific research appliances. Its disassembly and handling are relatively simple; The other is waste electronic products, which are made of complex materials and harmful to the environment, such as lead in computer and TV picture tubes, arsenic and mercury in computer components.
A variety of persistent and bioaccumulative toxic substances such as arsenic, cadmium and lead in mobile phone raw materials.

First, the application status of electronic products
With the progress of society and the continuous development of science and technology, electronic products have brought convenience to our daily life, such as mobile phones, computers, old people in their sixties and seventies and children in their sixties and sevens. While mobile phones and computers bring us convenience, they also bring us harm. Now the mobile phone has brought us a lot of convenience, such as shopping on Taobao, searching for the information we need online, and now paying with WeChat and Alipay, without fear of losing money, you can use mobile navigation, mobile phone positioning, * * * positioning, making information and so on. It has brought us great convenience, but mobile phones have also brought us a lot of harm. For example, let children have poor self-control, easy to indulge in online games, difficult to control themselves, leading to unintentional learning. It may even make parents feel helpless because they quarrel with their parents on their mobile phones, which is not conducive to their children's growth. Because of the mobile phone, many children don't exercise and indulge in games, which leads to poor eyes, poor physical coordination and even online violence and pornography, which will affect their physical and mental health. These disadvantages make parents very helpless. In a word, electronic products are like a double-edged sword. Good use will benefit the people, and bad use will harm the people. If parents can effectively manage their children, I believe that the advantages of the development of electronic products outweigh the disadvantages. Electronic products have promoted social and economic development, made our life more convenient and made great contributions to social and economic development.
