Cadmium (Cd) Levels In The Blood Of Communities Consuming Mystus Gulilo Around The Kenjeran Beach Area Of Surabaya With Atomic Absorption Spectrophotometry Method

Abstract

Cadmium is heavy metal with a toxic effect in the body, which is found in the environment of soil, air and water.
Mystus Gulilo is one type of fish that can survive in polluted water such as Kenjeran Beach Surabaya, which is
contaminated the heavy metal, cadmium. Mystus Gulilo that is consumed by humans accumulates in blood, settles
for 75-128 days, and binds low molecular weight proteins that causing health problems, nerve damage, kidney
damage, and red blood cell damage. This research is a descriptive study. The population in this research is the
people who consume fish. The research specimens is blood, which taken by purposive sampling, requires people
who consume Mystus Gulilo regularly for the last 1-3 months and aged 25-60 years. The research was carried out
at the Surabaya Health Laboratory Center by using Atomic Absorption Spectrophotometry (AAS) apparatus. The
results showed 3 respondents had a cadmium level exceeding the normal value with an average of 0.186 µg/dL,
The age factor and the level of consumption affect the value of cadmium levels. The higher a person's age and the
consumption levels of Mystus Gulilo they have, the higher the value of cadmium levels in their body and can cause
chronic poisoning because the poison contained in the metal is carried to the body and accumulates over a long
period of time, having an impact on the body's health, causing organ damage to death.
