Abstract
In this study, heavy metal levels in muscle and liver tissues of different age groups of Lagocephalus sceleratus caught in the Mersin Bay were investigated. Six different age groups were determined among fishes caught using commercial trawlers from the Mersin Bay. The lengths of fish were measured between 17 cm and 68 cm, the weights were measured between 265 g and 3955 g. Cadmium (Cd), Lead (Pb), Chromium (Cr) and Arsenic (As) levels were investigated using ICP-MS. The heavy metal concentrations in the liver and muscle tissues in L. sceleratus were found to be As>Cr>Cd>Pb and As>Cr>Pb>Cd, respectively. It was observed that with the increased ages of pufferfish, the levels of heavy metals determined in both muscle and liver tissues were increased.
Highlights
Environmental pollution is one of the major problems of our global society
Heavy metals are elements that are considered to be toxic for a long time and that are harmful to human health or ecosystems if limit values are exceeded
Heavy metal levels (Cd, Pb, As and Cr) in the liver and muscle tissues of pufferfish are shown in Table 2 and Figure 2
Summary
Environmental pollution is one of the major problems of our global society. Metal pollution is an important element of environmental pollution. Heavy metal contamination is a problem that has had a very negative impact on human nutrition and human health (Kulcu et al, 2014) Environmental elements such as water, air and soil can be influenced by exposure to metals, people are most exposed to metals with food. As a general belief, seas are still seen as a compensatory system of pollution (Bjerregaard et al, 2015, Nordberg et al, 2015) This situation has led to dramatic levels of metal contamination, especially in marine ecosystems. Marine organisms consumed by humans can act as a source of nutrients, but they are effective in spreading the effect of pollution For this reason, the heavy metal levels of living things collected from natural habitats are an important indicator of the potential risks for human health and heavy metal contamination in living areas
