Electronic Waste - Speech or Presentation Example Developed nations have made several steps towards ensuring e-waste management. On the other hand, developing nations lag behind and so far policies enacted as not fully implemented. In most developed nations, there are no policies that govern the disposal of electronic materials (Karpus, 1). This, therefore, implies that e-waste is posing several challenges in many nations.à Electronic wastes are made up different materials that are extremely toxic. Some of these materials cannot be decomposed or decompose at a unusually slow rate (Toothman & Elizabeth, 1). Toxic Components of E-Wasteà à à à à à à à à à à à à à à à à Smoke alarms contained in many electronic devices are made up of americium or carcinogen. This two materials are radioactive and take a very long to decompose. Mercury is used to make tilt switches, fluorescent tubes, flat screen monitors and thermostats. If mercury is absorbed into the environment, it results into serious health eff ects such as dermatitis, sensory impairment, general muscle weakness, and memory loss in human beings and reduced fertility, death, slower rate of growth and development in animals (Karpus, 1). Lead acid batteries are made up of particularly harmful chemical called sulphur. If absorbed into an individualââ¬â¢s body it causes adverse effects such as kidney damage, throat and eye irritation, and heart damage.

Lead acid batteries are made up of particularly harmful chemical called sulphur. If absorbed into an individualââ¬â¢s body it causes adverse effects such as kidney damage, throat and eye irritation, and heart damage. When allowed to reach the clouds, it reacts with vapor to form sulphuric acid (Toothman & Elizabeth, 1). BFR is used in most electronics as flame retardants. It is made up of other several chemicals, which when allowed to the environment causes several health complications. These include liver problems, thyroid problems, and impaired nervous system development both in animals and human beings (Grossman, 1). Cadmium is used to make light sensitive resistors and nickel cadmium rechargeable batteries used in electronic devices. Cadmium has adverse effects if ex posed to the environment. If inhaled, it causes permanent damage to the lungs as well as causing kidney diseases. Due to its adverse effects, it was banned in Europe except for medical purposes (Toothman & Elizabeth, 1). Lead is a vital component of most electronic devices including monitors, solders, lead-acid batteries, cathode ray tubes and PVC. Lead if allowed into the soil will encourage leaching and destroy natural habitats for many micro-organisms. Beryllium is used as filler in thermal materials. These include thermal grease that is used in CPUs and heat sinks, X-rays ceramic windows, vacuum tubes, and gas lasers (James, 13). If all of these harmful chemicals are released into the environment then our future generations are threatened. Most animals will get extinct the generations that
