In the context of biomedical wastes, we mean wastes produced during diagnosis, treatment or vaccination of humans and animals. This also includes wastes created in connection with research or testing biological specimens. Biochemical specimens include any preparations made with organisms and micro-organisms as well as products from metabolism or biochemical reaction intended to be used in diagnosis, immunization, treatment of animals or humans or research – continue reading?
Health care waste includes various materials such as used needles, syringes, soiled dressings or body parts, diagnostic specimens, blood, drugs, medical equipment, and radioactive material. Health care waste management can lead to contamination, injury and even death for health care workers and waste handlers. Medical wastes must be properly treated, sorted and disposed at their source. In the bottom or fly-ash of incinerated plastics (PVC), dioxins,furans and toxic air pollutants are produced when low temperature wastes incinerated. The combustion of wastes that contain polyvinyl chloride can produce toxic dioxins, PCBs (co-planar) and furans. The toxic substances dioxins (furans), co-planar pcbs, and others are then produced in the bottom or flyash.
When there is a well-functioning infrastructure, it’s possible to safely dispose of the waste produced by rural clinics and larger hospitals. WHO reported that in 2000 contaminated injections and contaminated needles had caused 21,000,000 hepatitis B (HBV) infection (32% of new infections), 2,000,000 hepatitis B (HCV), infections (40% new infections), as well as at least 260000 HIV infections (5%) The results of an assessment by WHO in 2002 conducted in 22 developing nations showed that 18% to 64 % of the health care facilities did not dispose of waste properly.
