“…This is because As, especially (AsO 4 ) 3− , competes with inorganic P transporters. Atici et al [28] observed the seasonal variation in the patterns of heavy metal accumulation and the stress of the phytoplankton in a freshwater body, Sariyar Dam Lake in Turkey. The heavy metal accumulation pattern in plankton samples in all four seasons was the same as Pb > Cr > Cd > Hg, in agreement with the bioavailability of these metals in the same order in the lake water samples of the freshwater system, showing a directly proportional relationship between metal abundance and bioabsorption by phytoplankton.…”

Several types of contaminants are anthropogenically introduced into natural aquatic ecosystems and interact with other chemicals and/or with living organisms. Although metal toxicity alone has been relatively well studied, the toxic metal ion effects in the mixture have been thoroughly studied only during the last decades. This review focuses on the published reciprocal effects of different metals on different species of algae, together with describing their toxic effects on studied parameters. Phytoplankton as a bioindicator can help to estimate the reciprocal metal risk factor. Many methodologies have been developed and explored, such as the biotic ligand model (BLM), concentration addition (CA), independent action (IA), sensitivity distribution of EC50 species sensitivity distribution (SSD curves), and others, to study reciprocal metal toxicity and provide promising results, which are briefly mentioned too. From our review, we can commonly conclude the following: Zn acted antagonistically with most heavy metals (Al, Cu, Cd, and Ni). The Cu interaction with Cd, Fe, and Pb was mostly antagonistic. Cd showed synergistic behaviour with Hg, Cu, Zn, and Pb and antagonistic behaviour with Co and Fe in many cases. Methods and techniques need to be developed and optimised to determine reciprocal metal toxicity so that the ecotoxicological predictions made by using phytoplankton can be more accurate and related to real-time toxic metals risks to the aquatic ecosystem. This is the main objective of ecotoxicological tests for risk assessment. Understanding how metals enter algal cells and organelles can help to solve this challenge and was one of the main parts of the review.

“…7389 Tahun 2009 tentang Batas Maksimum Cemaran Logam Dalam Pangan dengan Nilai Logam Berat Kadmium (Cd) adalah 100 ppb atau 0,1 mg/L. Logam berat di lingkungan perairan merupakan jenis pencemaran utama yang mengancam kehidupan perairan dan manusia serta memiliki efek negatif yang dapat mengganggu keseimbangan ekologi lingkungan dan keanekaragaman organisme perairan (Atici, 2008). Kontaminan logam berat yang masuk ke dalam tubuh ikan nila (Oreochromis niloticus) melalui beberapa cara, yaitu sistem sirkulasi (peredaran darah) dan sistem ekskresi.…”

Aktivitas di Sungai Kapuas Kecil terdiri dari aktivitas transportasi air, domistik, industri seperti industri galangan kapal dan budidaya ikan atau dikenal sebagai keramba jaring apung (KJA). Sekitaran tepian Sungai Kapuas Kecil terdapat beberapa industri galangan kapal. Kegiatan industri galangan kapal merupakan produksi reparasi atau perbaikan kapal yang dimana industri ini berpotensi menghasilkan limbah cair yang berasal dari proses pengecatan kapal. Hasil limbah dari aktivitas industri galangan kapal diduga mengandung logam berat seperti Cd, Cr, Cu, Hg, Ni, Pb dan Zn. Logam berat yang bersifat sulit didegradasi dan tidak mudah terlarut dalam air yang dapat menyebabkan dampak negatif terhadap kualitas perairan sungai, selain itu logam berat yang berlebihan juga dapat mengganggu kehidupan biota periaran. Dari penjelasan diatas maka perlu dilakukan analisis terhadap ikan nila (Oreochromis niloticus) di KJA Sungai Kapuas Kecil. Pengujian kandungan kadmium (Cd) pada ikan nila (Oreochromis niloticus) menggunakan metode SSA (Serapan Serapan Atom). Hasil konsentrasi kadmium (Cd) ikan nila (Oreochromis niloticus) pada KJA 1, KJA 2 dan KJA 3 sebesar < 0,001 mg/L hasil tersebut masih dibawah baku mutu SNI No 7389 Tahun 2009 sebesar 100 ppb atau 0,1 mg/L. hasil pengujian pada daging ikan nila (Oreochromis niloticus) tersebut menunjukan hasil dibawah baku mutu yang dapat disimpulkan bahwa pencemaran logam berat kadmium (Cd) belum berdampak pada ikan di Sungai Kapuas Kecil.

“…Fish from freshwater are majorly exposed to various heavy metals, which are added into the water bodies through the different-different sources. Contamination of these heavy metals into aquaculture has intensified global issues because it shows a risk to fish and has harmful impacts on fish buyers [71]. There are three different modes through which heavy metals enter the fish.…”

The Toxicity of Environmental Pollutants

Water has become a major threat in today’s world. Collection of heavy metals, a few of them, is potentially toxic and these get distributed to different areas through different pathways. With an increase in the earth’s population, development and industrialization are taking place rapidly and these get the major source of water contamination. With heavy metals in lakes, rivers, groundwater, and various water sources, water gets polluted by the increased concentration of heavy metals and metalloids through release from the suddenly mine tailings, disposal of high metal wastes, growing industrial areas, leaded gasoline and paints, usage of fertilizers inland, animal manures, E-waste, sewage sludge, pesticides, wastewater irrigation, coal, etc. Exposure to heavy metals has been linked to chronic and acute toxicity, which develops retardation; neurotoxicity can damage the kidneys, lead to the development of different cancers, damage the liver and lungs; bones can become fragile; and there are even chances of death in case of huge amount of exposure. This chapter mainly focuses on heavy metal pollution in water and its toxic effect on living organisms.
