Today I’m going to talk about: Hazardous wastes I’ve divided my presentation into two parts: First I’d like to introduce the wastes and second I’ll present sourcesof hazardous wastes. So, let’s start with introduce Hazardous Wastes, solid, liquid, or gas wastes that can cause death,illness, or injury to people or destruction of the environment ifimproperly treated, stored, transported, or discarded. Substances areconsidered hazardous wastes if they are ignitable, corrosive, reactive, ortoxic. Mixtures, residues, or materials containing hazardous wastes arealso considered hazardous wastes. Many dangerous substances can be used only with special precautionsthat decrease their risks. When discarded, these substances are no longerunder the direct control of the user and may pose special hazards to peopleor other organisms that come in contact with them. Because of suchpotential risks, hazardous wastes are processed separately from ordinarywastes. There are foor sources of hazardous wastes: Industrial, Agricultural,Household and Medical. A Industrial Wastes Hazardous wastes are generated by nearly every industry; thoseindustries that themselves generate few hazardous wastes nonetheless useproducts from hazardous waste generating industries. Other hazardous wastesare generated in the manufacture of fiber optics and copper wire used inelectronic transmission, as well as magnetic disks, paper for technicalmanuals, photographs for packaging and publicity, and trucks fortransportation of the finished product. B Agricultural Wastes Industry is not alone in generating hazardous wastes.
