“…Pure arsenic is rarely found in nature and is not very toxic, but it can be oxidized easily in humid air and become toxic by conversion to arsenic anhydride. Arsenic, which has four different oxidation steps, is mostly in the form of +3 and + 5 valences in nature [1,11,12].…”

Heavy Metals - Their Environmental Impacts and Mitigation

View full text Add to dashboard Cite

Fast consumption, increasing energy needs, unplanned urbanization, and unconscious discharge of industrial wastes cause pollution of air, soil, food and water resources. Among these pollutants, heavy metals and metalloids are not biodegradable and accumulate in compartments such as water, soil and plants, threatening human and environmental health. Monitoring studies show that heavy metals such as arsenic, lead, mercury, cadmium, nickel, zinc, copper, chromium and trace elements are in first place according to their availability in the environment. Preventive and remedial measures should be taken to reduce the effects of heavy metals. Legal regulations, monitoring studies, the use of soluble and non-toxic compounds in environmental compartments (air, water, soil and plants) in industrial processes, heavy metal-free pesticides, appropriate wastewater treatment plants and use of renewable energy sources instead of fossil fuels are among the priority measures to reduce concentrations of heavy metals in the environment. As a bioremediation approach, removing toxic wastes from the environment by using bioaccumulatory organisms such as plants or mussels maintains its importance among studies aimed at recovery. Studies have shown that integrated methods - especially the combination of suitable plants and microorganisms - are very effective in mitigating the effect of heavy metals in the environment.

“…Results indicated that the investigated samples were moderately contaminated with Ag, Cr and As, moderately to severely contaminated with Zn and Ni, and severely contaminated with Cu. 30 Our previous study conducted between 2011-2012, a study on marine pollution in the region identified Pb, As, and Cu levels above those permitted by the Turkish Food Codex in shrimp sample collected from the coasts of Tekirdağ 31 .In addition, another research is to determine the mercury, lead and cadmium accumulation in scads (Trachurustrachurus) caught in the near Tekirdag in the sea of Marmara in 1996. Fish sample average mercury contents were 0.029 ppm and average lead contents were 0.038 respectively.…”

Objective: The aim of this report is to evaluate the heavy metal pollution of the Ergene Basin and its effects on public health. Methods: Local people, as well as the surrounding ecosystem, are exposed to varying levels of chemical substances. Those working in different industrial sectors are particularly vulnerable. Ergene river, one of the most important water sources in the Thrace region, is being rapidly polluted due to increasing industrialization and urbanization in the region. Many chemicals are discharged into the Ergene river without proper treatment. This is largely due to the inadequacy of residential and industrial treatment plants, as well as the proliferation of illegal dumping in the region. Thus, both the environment and the people face a serious threat. For many years there have been many studies investigating the presence and effects of heavy metals on the water, soil, air, plants, animals and people of the region. In our study, the literature on heavy metal concentrations in the region was summarized and the five-year cancer statistics were evaluated. Results: The lead concentration, which is a common metal in all the different environmental compartments, has been found to be above the maximum limit value. Furthermore, the evaluation of cancer data showed an increase in all cancer types between 2006 and 2011. Conclusion: Although it is difficult to relate cancer and environmental factors directly, studies show that there may be a close relationship between lead concentration (largely produced by the textile and leather industries) and the occurrence of bladder and kidney cancers. However further research, such as risk assessments, is required to establish more definitive conclusions.

Pollution affects all biomes. Marine environments have been particularly impacted, especially coral reefs, one of the most sensitive ecosystems on Earth. Globally, 4.5 billion people are economically dependent on the sea, where most of their livelihood is provided by coral reefs. Corals are of great importance and therefore their extinction leads to catastrophic consequences. There are several possible solutions to remediate marine pollutants and local contamination, including bioremediation. Bioremediation is the capacity of organisms to degrade contaminants. The approach presents several advantages, such as sustainability, relatively low cost, and the fact that it can be applied in different ecosystems, causing minimal impacts to the environment. As an extra advantage, the manipulation of endogenous microbiomes, including putative beneficial microorganisms for corals (pBMCs), may have probiotic effects for marine animals. In this context, the use of the two approaches, bioremediation and pBMC inoculation combined, could be promising. This strategy would promote the degradation of specific pollutants that can be harmful to corals and other metaorganisms while also increasing host resistance and resilience to deal with pollution and other threats. This method focuses on the selection of pBMCs to degrade two contaminants: the synthetic estrogen 17a-ethinylestradiol (EE2) and crude oil. Both have been reported to negatively impact marine animals, including corals, and humans. The protocol describes how to isolate and test bacteria capable of degrading the specific contaminants, followed by a description of how to detect some putative beneficial characteristics of these associated microbes to their coral host. The methodologies described here are relatively cheap, easy to perform, and highly adaptable. Almost any kind of soluble target compound can be used instead of EE2 and oil.

For instance, 4.5 billion people depend on ocean fish as their main food source 16 , which are greatly supported by coral reefs. Regardless of their ecological, social, and economic importance, coral reefs are being decimated 17,18. Anthropogenic activities are primarily responsible for contributing to the three main causes of corals' death: climate change, overfishing, and water pollution 19. Even though it is important to work on the mitigation of global warming, it is also important to work on minimizing local contamination, including water pollution,
