Abstract—Heavy metals are considered as a major pollutant causing environmental cytotoxic, mutagenic and carcinogenic effects in animals and aquatic organisms. Pollution caused by these substances can arise from many sources and the major problem associated with its persistence is its potential for bioaccumulation. Heavy metals such as lead (Pb), cadmium (Cd) and chromium (Cr) are the most common toxicant that can be found in the marine environment including fish. Fish is a common table food consumed by humans for protein nourishment and its use to study heavy metal contamination would benefit majority of individuals living in a country surrounded by bodies of water, such as the Philippines. The study aims to analyze the presence of lead, cadmium and chromium using qualitative and quantitative tests in the head, meat and internals of selected fish samples sold in wet markets located at Metro Manila, Philippines. Quantitative analysis confirmed the presence of lead, cadmium and chromium in all fish samples. Results were reinforced by the Flame Atomic Absorbance Spectroscopy, wherein most of the fish samples exceeded the standard limits set by US-EPA and FDA for lead, cadmium and chromium i.e. 0.5, 0.05 and 0.1 ppm respectively. Single factor ANOVA have shown that there is no significance among the levels of lead, cadmium and chromium with p values of 0.3679, 0.8858 and 0.9593 respectively in the head, meat and internal organs of the fish samples. Therefore, a person will acquire the same amount and effect of the heavy metals regardless of the part of the fish to be consumed. This study would be useful for the creation of guidelines to protect the public from the harmful effects of the toxicants present in fish that is consumed by the public.
