HUBUNGAN AKUMULASI TIMBAL PADA RAMBUT MASYARAKAT PENGUMPUL LIMBAH BATUBARA DENGAN PENYAKIT HIPERTENSI

Abstract

The water contamination in one place can affect the other places located far from
the source of pollution. One of the rivers that are polluted is Bengkulu river. One of the
causes of pollution in Bengkulu river that is coal waste originating from coal mine company
in the upstream of the river, which is still in service until now. The coal handling treatment as
crushing, grinding, washing, drying and low temperature combustion can cause any harmful
chemical substances like lead. Lead can get into the human body through the digestive tract
absorption or through the respiratory tract (inhalation) and skin absorption. One way of
disposal of heavy metal elements from the body is to accumulate in the hair, so the hair
analysis is a good way to estimate the content of heavy metal elements in the body and
determine its connection with hypertension. The purpose of this study is to determine the
content of lead in a coal waste accumulates in hair of coal waste collectors society in
Bengkulu river associated with hypertension. This study is an analytic observational study
with cross sectional study design. The case that will be studied is about the accumulation of
hair lead of coal waste collectors society in Bengkulu river against hypertension. The study
location is in Bengkulu river. Sample examination was conducted by Atomic Absorption
Spectrophotometry (AAS) analytical methods, and then performed statistical tests to
determine its connection with hypertension. The result of this study showed, from 40
respondents there were 14 respondents (35%) who had hair lead levels > 12?g/g suffered
from hypertension and 13 respondents (32.5%) who had hair lead levels > 12?g/g but did not
suffered from hypertension, and p(0.03)< 0.05 value which indicates a significant association.
Significant association between the levels of lead in the hair of coal waste collectors society in
Bengkulu river with hypertension
