What research shows about biodiversity, water/sediment quality and underwater noise pollution

<p>Initial estimates showed no significant impact on the biodiversity of the Blue Lagoon area on the Akama Peninsula, which apparently did not appear to be affected by tourism activities. However, underwater noise pollution during the arrival, anchoring and departure of vessels was noticeable, a fact which is confirmed by the high readings recorded by a special hydrophone used during the sampling.</p>
<p>The above findings were extracted from the research conducted by the Cyprus Marine and Maritime Institute (CMMI-Cyprus Marine and Maritime Institute) with the support of the Bank of Cyprus, which lasted one year (2023-2024) and aimed to identify potential impacts that intense tourism activities bring to the natural integrity of the marine ecosystem in the 'Blue Lagoon' bay of the Akama Peninsula.</p>
<p>In addition, in the marine sediment during the summer season, copper values ​​were observed, which exceed the environmental limits, which is probably due to the increased passage and anchoring of boats in the area, since the antifouling paints often used on the exterior of boats have as a component the copper. Exposure to high concentrations of copper can be environmentally damaging, since they can alter the photosynthetic capacity of algae and affect the growth of other important benthic organisms (e.g. corals) among others. Heavy metals, such as copper, can also bioaccumulate in fish and molluscs affecting the food chain.</p>
<p>The importance of the present study lies in the fact that it lays the groundwork for long-term study of the possible effects of increased tourist activity in the 'Blue Lagoon' bay.</p>
<p>Scientists from CMMI conducted seasonal sampling (Spring, Summer, Fall, Winter) in the Blue Lagoon area to collect water and sediment samples for analyzes aimed primarily at identifying various chemical contaminants (e.g., heavy metals, sunscreens) and microbiological organisms, and to record environmental parameters and the area's biodiversity (fish fauna and benthic organisms).</p>
<p>The “Seamachia for cleaner seas” program is an initiative of the Bank of Cyprus with the aim of scientific research and generation of coastal marine water quality data. In 2022-2023, a survey was carried out in the sea area of ​​the Ayia Napa Marina, in collaboration with the NGO CYMEPA and the Cyprus University of Technology (TEPAK), the results of which were announced at the end of 2023.</p>
