The Relationship Between Lead (Pb) Levels in Blood and Kidney Function in Farmers in Tanggulangin Subdistrict, Sidoarjo Regency

Abstract

Lead is one of the heavy metals that can be found in pesticide formulations and has carcinogenic properties. Lead exposure tends to accumulate in the blood after entering the body through various exposure routes, potentially causing proximal tubule damage and leading to chronic kidney disease. The aim of this study is to analyze the relationship between blood lead (Pb) levels and kidney function in farmers in Tanggulangin District, Sidoarjo Regency, using AAS (Atomic Absorption Spectrophotometry) and a photometer. This study is a correlational study conducted at the BSPJI laboratory and the Clinical Chemistry Laboratory of the Medical Laboratory Technology Department at Poltekkes Kemenkes Surabaya from March to May 2024. The population in this study consists of farmers, with a total of 30 blood samples collected using purposive sampling. The results of the study regarding blood lead levels in farmers showed that 29 respondents had normal levels, while 1 respondent had abnormal levels. Meanwhile, 9 respondents had abnormal creatinine and BUN levels, and 21 respondents had normal levels. The conclusion of this study is that there is no relationship between blood lead levels and kidney function in farmers in Tanggulangin District, Sidoarjo Regency.
