In this study,
monthly change of the heavy metal composition of tellina (Donax trunculus Linnaeus,
1758) from Kefken territory on the Black Sea coast between 2013 and 2014 was
investigated. Heavy metal analysis was determined by ICP-OES. Mercury (Hg) and
tin (Sn) were not detected during the period of 12 months. Lead (Pb) was
detected in November, December, January, February, and March and it was
calculated as 12.97 μg/g on average. The highest amount of lead was detected in
December as 16.08±0.82 μg/g. The amounts of cadmium (Cd), cobalt (Co) and
nickel (Ni) were determined between November and April and it was seen that
they had average values such as 0.45 μg/g Cd, 0.91 μg/g Co and 4.46 μg/g Ni.
Chrome was detected during the 12 months and it was calculated as 4.19 μg/g on
average. The highest and the lowest amounts of chrome were detected in January
as 16.71±2.11 and August as 0.70±0.05, respectively. In addition, it was seen
that during the period this study was held, between 2013 and 2014, there were
dramatic temperature changes and the instant temperature changes positively
affected the accumulation of heavy metal in the species. Despite the fact that
the instant temperature changes positively affect the accumulation of heavy
metals in the live metabolism, it is better to handle the subject regarding the
effects of global warming on living things. It is possible to say that tellina
can be consumed as food in convenient times. In respect of the detections in
this study, it can be said that tellina can be conveniently consumed between
April and October depending on the territory.
