| الملخص: | ýAnthropogenic
activities have given great pressures on the environment including the river and
therefore public awareness is important in order to sustain our natural resources. This study was
carried out to analyze the heavy metals concentrations of the surface water of four stations within
Sg. Maong catchment and also to investigate the environmental awareness of the villagers in
Kpg Sg. Maong with regard to solid waste management and recycling. Elemental concentrations
of Zn, Fe, Pb, Cu, As and Al were measured using atomic absorption spectroscopy (AAS). The
mean values of the heavy metals are; Zn 0.91 mg/L; Fe 0.61 mg/L; Pb 0.018 mg/L; As 0.033
mg/L; Al 1.85 mg/L; whereas Cu was not detected in all water samples. The average trend of
heavy metals in Sg. Maong was observed in the order: AI>Zn>Fe>As >Pb. Pearson correlation
analysis was done to determine the degree of association between the heavy metals and pH. Fe
and As showed high correlation with pH whereas between metals, Zn/Fe, Zn/Al, Fe/As and
Fe/Al showed a positive correlation)lt was observed that the surface water of Sg. Maong was not
heavily contaminated with Fe, Zn, Al and Cu as these concentrations were below the standard
limit of Interim National Water Quality Standard (INWQS). At the same time, a convenience
sampling method was conducted in Kpg. Sg. Maong to investigate the villages' awareness
through scheduled interviews. The questions were categorized into five sections which are
environmental awareness, water awareness, solid waste management, recycling awareness and
demography. The finding shows that most of the respondents exhibited positive answers towards
different awareness. Thirty households were interviewed in this study and the chi-square test was
conducted to examine the significant difference between the independent variables with the
dependent variables. Results indicate that there are significant differences between age, gender
and education of the respondents. |
