About this project
This chemistry project determines the concentration of heavy metals (lead, cadmium, chromium, zinc) in vegetables irrigated with wastewater using atomic absorption spectrophotometry. It compares levels with WHO/FAO permissible limits, computes daily intake estimates and health risk indices, and advises on the safety of urban wastewater agriculture.
Methodology
Laboratory analysis
Chapters 1–5 outline
Chapter 1
Introduction: background to heavy metals in wastewater-irrigated vegetables, statement of the problem (urban farmers increasingly irrigate with untreated wastewater of unknown safety), aim and objectives, research questions, scope, significance of the study, and definition of terms.
Chapter 2
Literature Review: theoretical framework, review of related works on heavy metals in wastewater-irrigated vegetables, gaps in existing studies, and a summary positioning this project.
Chapter 3
Methodology / System Analysis and Design: experimental design; AAS analysis; health risk assessment. Includes data collection method, system requirements, use-case and architecture diagrams (or population, sample size, and instrument).
Chapter 4
Implementation and Results: metal concentration tables, risk indices and safety recommendations. Presentation of findings, testing, evaluation, and discussion of results.
Chapter 5
Summary, Conclusion and Recommendations: key findings, contribution to knowledge, limitations, and recommendations for further research.
