Abstract

Heavy metal pollution is one of the problems that often occurs in Indonesian coastal waters. Comparative methods of looking at heavy metal content in coastal sediments include a way to show similarities and differences between one or more articles by using certain criteria. Different comparison methods to see the heavy metal content in sediments include the AAS (Atomic Absorption Spectrophotometer) method, AAN (Netron Activation Analysis), Regression, and USEPA methods. Based on the comparison of 2 methods, namely: AAS and AAN methods, the most efficient in analyzing heavy metals in sediments in coastal areas is the Atomic Absorption Spectrophotometry (AAS) method compared to the Neutron Activation Analysis (AAS) method.Keywords:CoastalSedimentHeavy MetalSpectrophotometer

Highlights

Coastal waters are waters that are very susceptible to various kinds of pressure, one of which is heavy metals
The Neutron Activation Analysis (AAN) method has several advantages over other methods, namely it can determine the type of element and its content (Wijayanti, 2010), does not damage the sample (Purwandhani, 2007), has a higher sensitivity to nanograms (10-12 g) (Mireles et al, 2011), can distinguish each isotope from the same sample, and can be used to determine the content of metallic elements in liquids, solids and gases (Purwandhani, 2007), and use relatively few samples (50-100). 100 mg) (Wijayanti, 2010)
Among the various descriptions above, the Atomic Absorption Spectrophotometry (AAS) method is efficient in analyzing heavy metals in sediments in coastal areas compared to the Neutron Activation Analysis (AAS) method

Summary

Introduction

Coastal waters are waters that are very susceptible to various kinds of pressure, one of which is heavy metals. Amin et al (2011) stated that one of the pollutants that has the potential to reduce and damage the carrying capacity of the coastal environment is heavy metal. Heavy metal pollution is one of the problems that often occurs in coastal waters (Lestari, 2004). Indonesian Coastal Areas are very vulnerable to pollution, especially related to heavy metals in sediments (Effendi et al, 2017; Mahidin et al, 2021). The results of the heavy metals study in sediments can directly affect the aquatic ecosystem. It will cause contamination of aquatic biota such as fish, shrimp and shellfish, where these biota live on the bottom of the waters. Based on the case study of Rochyatun et al (2006) the content of heavy metals in sediments is higher than in water, this indicates an accumulation of heavy metals in the sediments (Irham et al, 2019)
