Physico-chemical quality of ashes post-incineration and waste from laboratory automaton biochemistry, hematology and serology in Togo
Biochemistry, hematology and serology laboratories produce very heterogeneous discharges capable of polluting water, soil and the environment. The aim of this study is to evaluate the physico-chemical quality of the ashes, effluents and the range of equipment that produce the much effluent and pollu...

| description | Biochemistry, hematology and serology laboratories produce very heterogeneous discharges capable of polluting water, soil and the environment. The aim of this study is to evaluate the physico-chemical quality of the ashes, effluents and the range of equipment that produce the much effluent and pollutions.This is a descriptive and cross-sectional study of 82 laboratories followed by the sampling of effluents from automatons. The physico-chemical parameters and trace elements are determined according to French Standardization Association (AFNOR) standards and used atomic absorption spectrometers and molecular absorption spectrometers. The Mindray hematology automaton is used for 64.7% and 81.5% of the cans are used to collect waste. Semehow 77.8% of discharges are released into sinks without adequate treatment in 42.6% of cases. Chemical analyses show that trace elements (TE) levels in effluents range from 5.89 ± 0.21 to 105.80 ± 0.96 μg/L for Arsenic; from 5.62 ± 0.34 to 6.53 ± 0.49 μg/L for Cadmium; 0.70 ± 0.01 to 10.63 ± 1.17 μg/L for Mercure and 35.72 ± 1.88 to 61.98 ± 5.15 μg/L for Plomb. pH ranges from 7.17 ± 0.65 to 8.3 ± 1.35 with total dissolved salts (TDS) range from 3260.20 ± 401.68 to 17117.41 ± 265.37 mg/L. All averages of contamination indices (CI) and polymetallic contamination indices (PCI) for post-incineration ashes are greater than 1.5 with the exception of Hg (0.22). For effluents, in addition to polymetallic contamination indices (PCI), CI in hematology effluents (1.09), all CI are less than 1. Hematology effluents have a lower pH and are much more mineralized and concentrated in trace elements while those from biochemistry and serology appear to be similar. However, the effluents of Biochemistry and Serology are more basic and concentrated in Suspended Solids with higher values obtained in Biochemistry. Although the physico-chemical parameters comply with WHO standards, discharges from automatons deserve appropriate treatment before their disposal. |
