ANALISIS KONSENTRASI TIMBAL (Pb) PADA AIR, IKAN DAN TIRAM DI PESISIR BARU TENGAH BALIKPAPAN TAHUN 2022

Abstract

Background & Objective: Coastal pollution can come from human activities which can contain lead that can contaminate waters and accumulate in marine biota and give an impact on the health. Inform ation regarding lead pollution in the waters and marine biota on the coast of Baru Tengah is still limited. This study aims to analyze the concentration of lead in water, fish and oysters on the coast of Baru Tengah against environmental quality standards and determine the level of health risk. Method: The type of research is quantitative with descriptive method and on-desk analysis of lead health risk level. The measurements of temperature, pH, dissolved oxygen and salinity of the waters were also carried out. Heavy metals were analyzed using the Atomic Absorbed Spectrometer (AAS). Results: The results showed that the concentration of lead in the water at each station and the fish studied was still below the environmental quality standard. The concentration of lead in oysters at all observation stations has exceeded the environmental quality standard with the highest concentration at station 1 is 4,167mg/kg and the lowest at station 3 is 2,799 mg/kg. Oysters at stations 1 and 2 have an unsafe level of health risk (RQ>1). Conclusion: Based on the results there had been environmental pollution by lead accumulated in oysters and there is a health risk by oysters at stations 1 and 2. Suggestions that can be done are to carry out control efforts such as controlling coastal space, realizing waste management regulations, periodically monitoring the environment, applying environmentally friendly technology, applying waste recycling principles, and measuring public health as a whole
