What is the most dangerous issues of hazardous waste? Write any six sources of hazardous waste that are common in Nepal.

The most dangerous issue of hazardous waste is that it can contaminate the environment and human health. The six sources of hazardous waste common in Nepal are:

  1. Industrial processes – This is one of the major sources of hazardous wastes in Nepal as factories and industries use large quantities of chemicals which, when discarded, form hazardous substances.

  2. Agricultural chemicals – These include pesticides, fungicides and insecticides used for crop production which leach into soil and water systems, posing potential risks to humans and wildlife.

  3. Automobile exhaust fumes – These contain volatile organic compounds such as carbon monoxide, nitrogen oxides, sulphur dioxide and lead which are all toxic to humans when inhaled or ingested in large quantities over a long period of time.

  4. Solid wastes – In Nepal this includes waste generated by households such as plastic bottles and packaging materials which may contain toxins like lead or mercury if not disposed properly; these can also leach into ground water systems if left unchecked.

  5. Medical waste – This includes biological material such as syringes or used bandages that can contain bacteria or viruses that could spread disease if not disposed properly; incineration is often the best way to dispose this type of hazardous material safely in Nepal..

6 Electronics waste - Old electronics that have been discarded by households can also be a source of pollutants due to their potentially high levels of heavy metals like mercury or lead; these should be recycled rather than thrown away so they do not pollute the environment unnecessarily..
