Gastropods As A Bioindicator and Biomonitoring Water Pollution

Abstract

Andi Nur Samsi, Ruzkiah Asaf, Sahabuddin, Andi Santi, and Muhammad Ikhsan Wamnebo. 2017. Review: Gastropods as A Bioindicator and Biomonitoring Metal Pollution. Aquacultura Indonesiana, 18 (1): 1-8. Water pollution effect on aquatic organisms and if consumed can affect people's health. These pollutants can be heavy metals such as Cd, Pb, Cr, Hg, and others. Heavy metals have high levels will cause disorders of the kidneys, brain, severe irritation to the skin, can cause diarrhea and even death. The purpose of this paper is to explain physiological mechanisms that occur in the body of gastropods are linked to pollutants in the water environment. Therefore, monitoring the level of pollution a body of water that is alleged to have suffered contamination is very important. Gastropods are one of the aquatic animals (Class) used as bioindicators and biomonitoring for this group of animals has a high ability to accumulate heavy metals in their bodies compared to other aquatic animals. Gastropods is one bioavailability against metal pollution so that it can be used for environmental monitoring. Littoraria scabra, Nassarius reticulatus, Nerita albicilla, Nucella lapillus, Gibberulus gibbosus, Terebralia palustris, and Telescopium telescopiun always use as biomonitoring metal pollution. The main indicator that can be shown by gastropods is declining abundance and body size. Other indicators are as bioavailability of heavy metals in the soft tissues and shells. The ability of the heavy metal deposits is influenced by environmental factors, body size, weight, and gender. Heavy metals can affect hard, thickness, volume, and color of the shell.

Bioaccumulation of some trace elements in tropical mangrove plants and snails (Can Gio, Vietnam)

“…Conversely, all snails were deconcentrators to microconcentrators for Mn and Fe. Due to negative effects of toxic trace elements on community structure, gender, size of snails (Amin et al 2009, Yap andCheng 2013), the obtained results in the present study provided a further claim that these snails can be used as good biomonitors for environmental quality (Samsi et al 2017).…”

“…The variations of trace metals concentrations in snails depend on their feeding regime, their digging activities, and metals bioavailability within their habitat. Snails can accumulate higher metals concentrations than any other groups of mollusks (Zhou et al 2008) and can offer the possibility to assess metals contaminations (De Wolf and Rashid 2008, Samsi et al 2017, Yap and Cheng 2013. It was demonstrated that elevated trace metals concentrations in sediments can influence negatively the number of snail species in an ecosystem as well as the community structure (Amin et al 2009).…”

Sediment Assessment of Al-Hindyia and Al-Abbasyia River / Iraq by aquatic oligocheata community as bioindicators

“…Many organisms such as plants, planktons, fishes are used as bioindicators 2 . The benthic macro invertebrates like Oligochaeta are most commonly used to evaluate the water health, they are subclass of class Clitellate, phylum Annelida, predominantly aquatic and terrestrial, used as an indicator for water and sediment quality 3. About 1700 rightful species of Oligochaetes are recognized to date; of these nearly 1,100 are freshwater.…”

Identification of Cyanide in Sediment of River in Hulawa Village

“…One of the indicators used to assess the accumulation of heavy metals in waters is air, river, and sea sediments (Vieira et al 2013;Palapa et al 2015;Ronoko et al 2019;Arifin et al 2020;Smits, 2014), and bioaccumulator microorganisms (Mehana et al 2020;Stankovic, 2013;Samsi et al 2017) that live in the waters around mining. The purpose of this study was to identify the cyanide content in river sediments in Hulawa Village.…”
