5.4 Relationship between ages, races and education level of respondents with the awareness on heavy metal contamination in water convolvulus
By using chi-square test, age of respondents is significantly associated with awareness on heavy metal contamination in water convolvulus (p=0.045). Based on Figure X, it can be concluded as the respondents in the age of between 18 and 54 years old are more aware on heavy metal contamination in water convolvulus compared to the age group between 55 until 65 years old and above.
There is no significant association between races of respondents and awareness on heavy metal contamination in water convolvulus (p=0.972).

Based on Figure X, the respondents from tertiary education and secondary school are more aware on exposure to heavy metal can cause health effects
5.6 Relationship between awareness on heavy metal contamination in water convolvulus with the awareness on exposure to heavy metal can cause health effects
Awareness on heavy metal contamination in water convolvulus is significantly associated with the awareness on exposure to heavy metal can cause health effects (p=0.000). Refer to Figure X, among 243 respondents who aware on heavy metal contamination in water convolvulus, only 30 respondents aware on exposure to heavy metal can cause health effects. While among 39 respondents who are not aware on heavy metal contamination in water convolvulus, there are 34 respondents who aware that exposure to heavy metal can cause health effects.
