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.
