This was a cross-sectional study and utilized interviewer administered questionnaire. The study employed purposive sampling among 256 PSP operators. Data were analyzed using descriptive statistics, Pearson’s product moment and multiple regression analysis correlation at 5% level of significance. Respondents’ age was 35.7 ± 4.2 years, and included 78.5% male. About 55.9% of the respondents spent up to 5 years in the waste management operations. Some 44.9% had at least completed secondary school education. A good knowledge of waste management was exhibited by 68.4% of the respondents. The respondents who had spent 16 years and above in waste management operations were more knowledgeable (8.0 ± 2.1) compared to those who had spent lesser time展开更多

This is a laboratory-based experiment involving optimization of amount of urine and dilution required for optimal growth of the test plants. Based on laboratory results, the experiments were scaled up. About 50 L of raw urine was collected from a male postgraduate student’s hall of residence, University of Ibadan, Ibadan, Nigeria. Water from Awba Dam, a natural lake within University of Ibadan, was used as the control. Viable seeds of Amaranthus viridis and Corchorus olitorius were collected from Department of Agronomy, University of Ibadan, and germinated in a nursery for 10 days before transplanting. The raw urine was diluted with varying amount of water in the ratio 1:1 through 1:50. Nutrients in urine media (nitrogen, phosphorus, potassium) and biomass indicators of plant growth (height, weight, number of leaves and leaf area) were determined using standard procedures. Urine dilution ratios below 1:25 did not support the experimental plants growth within a week. Plant height (cm), stem girth (cm), number of leaves (sheets) and leaf area (cm2) of Amaranthus viridis and Corchorus olitorius cultivated on Urine Dilution Ratio (UDR) 1:35 and 1:45 were higher at the end of week 3 compared to other dilutions and control. Percentage reduction of nutrients (NPK) in the media of Amaranthus viridis cultivated on UDR 1:45 was several folds higher (N = 59.9%, P = 100%, K = 55.3%) compared to that of UDR 1:35 (N = 38.5%, P = 49.1%, K = 37.6%). In the control water, the nutrients were totally removed during the experimental period. Growth of Corchorus olitorius cultivated on both UDR 1:35 and 1:45, was significantly higher at the end of week 6. A significant negative correlation was observed between Corchorus olitorius plant height and Phosphorus (r = -0.0418;p < 0.05) removal in the media. The study concluded that the use of diluted human urine for soilless cultivation of vegetables, if encouraged, could promote food security and environmental sustainability at household level in communities.展开更多

Information is inadequate on accessibility to sanitation and hygiene services in homes for the disabled in Nigeria. Purpose: To investigate accessibility to sanitation facilities and handwashing practices among Physically Challenged Persons (PCPs) in selected homes for the disabled in Ibadan. Materials and Methods: Sixty-four consenting PCPs selected from three homes for the disabled in a cross-sectional study were interviewed using questionnaire. Field observation and Focus Group Discussion (FGDs) were conducted using a checklist and FGD guide respectively. Results: Mean age of PCPs was 19.5 ± 6.8 years, and 56.2% were males. All PCPs reported they had water closet toilet-types in their homes, however, 42% reported that toilet usage was difficult because there were no assistive devices. Observation revealed there were no hand rails or ropes to aid in toilet usage. The FGDs revealed water supply for flushing was inadequate. Although 98.4% reported handwashing with soap after toilet use, only 54.7% of the PCPs reported that soap was readily available in their homes/centres. Discussion and Conclusion: Reports by the PCP and field observation showed that there were inadequate assistive devices such as wheelchair ramps, hand rails, or ropes to aid in toilet usage. Sanitation facilities in homes for the disabled should be appropriately built with necessary support to facilitate usage and easy accessibility.展开更多
