Abstract
Healthcareprovide services likecontrolling and preventing of communicable andnoncommunicable diseases. In the process of performing these activities, health facilities generally generate hazardous waste. The number of inpatient and outpatient are one of the factor that affect the generation rate of healthcare waste and it is different from hospital to hospital because of their specialization. The generation rate of hazardous and non-hazardous of solid healthcare waste has an environmental risk to the patient, healthcare worker and the environment at large. The general purpose of this study was to assess solid healthcare waste generation rate, composition, concentration of heavy metals and its management system in selected governmental hospital in Addis Ababa, Ethiopia. The study was conducted using cross-sectional, longitudinal and experimental method. The sample size was determined using simple random sampling technique. The generation rate and composition were collected using waste collecting andmeasuring equipment.Heavy metalin incinerated ash were analyzed using Atomic Absorption Spectrometer for the selected hospitals. The Data was analyzed using Microsoft excel version 2010 and SPSS version 20. The mean healthcare waste generation rate was 0.96kg/day/patient of which 0.46kg/day/patient (47.82%) was non-infectious waste and0.5kg/day/patient (52.18%) was infectious. The overall heavy metals concentration were found high concentration in copper and low concentration in cadmium and the descending order was Copper>lead>Cadmium>Chromium. A wide variation in trace concentration of several toxic elements has also been seen due to variation in initial waste composition, design of the incineration, the level of hospital and operating conditions.
