Table 2 presents pollutant factors that are grouped into four categories: water supply factors, drainage factors, air pollutant factors and solid waste factors. Each category includes several sub-factors that contribute to perceived health risks in the context of Indian villages. The perceived health risk factors listed in the table include hypertension, cancer, heart disease, gastrointestinal illness, asthma/COPD, psychiatric disease, frequent diarrhoea, skin problems and frequent illness. The table provides a comprehensive list of the factors that the study considered in developing a new model for health risk assessment that is coherent with quantitative benchmark-based health risks and considers multiple pollutant factors.
