Summary: This study has been conducted to determine the lead concentration and health risk assessment of the water and Tunsoy (Sardinella fimbriata) in Barangay Ligtong IV, Rosario, Cavite. The fish and water samples were collected from November 2023 to April at the three selected sampling sites in Manila Bay where the distance is over 500 meters (about 1640.42 ft). At least 500 ml (about 16.91 oz) of water and 500 grams (about 1.1 lb.) of fish were obtained at each sampling point every month during the five-month sampling period to determine their lead concentrations as well as the water’s pH and temperature. The samples were then analyzed in the laboratory right after labelling the water and measuring the fish's weight and dimensions. The laboratory used 3111B. Flame Atomic Absorption Spectroscopy (AAS) and Flame Atomic Absorption Spectrometric to identify the lead concentrations of the samples. The results were compared statistically using the Friedman and Pearson r correlation test. The data shows a high negative correlation between the lead concentrations of the fish and the water's pH level. According to the Estimated Dietary Intake (EDI) of lead concentrations in Tunsoy, only the month of January passed the maximum permissible limit of lead in fish as per recommended by Food and Agriculture Organization (FAO) and World Health Organization (WHO). Moreover, the noncarcinogenic target risk quotient (THQ) of lead concentration in Tunsoy showed that all the data from the five-month sampling were all below the recommended level of exposure (THQ<1). With that, the toxic effect of lead is not to be expected by the consumers that were exposed to Tunsoy that have been contaminated with lead.

This study has been conducted to determine the lead concentration and health risk
assessment of the water and Tunsoy (Sardinella fimbriata) in Barangay Ligtong IV, Rosario,
Cavite. The fish and water samples were collected from November 2023 to April at the three
selected sampling sites in Manila Bay where the distance is over 500 meters (about 1640.42 ft). At
least 500 ml (about 16.91 oz) of water and 500 grams (about 1.1 lb.) of fish were obtained at each
sampling point every month during the five-month sampling period to determine their lead
concentrations as well as the water’s pH and temperature. The samples were then analyzed in the
laboratory right after labelling the water and measuring the fish's weight and dimensions. The
laboratory used 3111B. Flame Atomic Absorption Spectroscopy (AAS) and Flame Atomic
Absorption Spectrometric to identify the lead concentrations of the samples. The results were
compared statistically using the Friedman and Pearson r correlation test. The data shows a high
negative correlation between the lead concentrations of the fish and the water's pH level. According
to the Estimated Dietary Intake (EDI) of lead concentrations in Tunsoy, only the month of January
passed the maximum permissible limit of lead in fish as per recommended by Food and Agriculture
Organization (FAO) and World Health Organization (WHO). Moreover, the noncarcinogenic target
risk quotient (THQ) of lead concentration in Tunsoy showed that all the data from the five-month
sampling were all below the recommended level of exposure (THQ<1). With that, the toxic effect
of lead is not to be expected by the consumers that were exposed to Tunsoy that have been
contaminated with lead.
