sea snot is more acidic than sea water. It was found that when nitrogen and
phosphorus were added, pH value increased and the environment became
more acidic. Marine creatures are fitted to live in the aquatic environments
with basic characteristics, but it is difficult for them to adapt to living in an
acidifying environment. It was observed that conductivity of sea water
increased after the nitrogen and phosphorus fertilizer was added (from -68,7/-
58,5 mV to -8,3-14,8 mV). On the other hand, it was detected that the electrical
conductivity of sea snot increased from 18.1 MV to 36.00 MV.

Figure 6. Physical properties of sea water and mucilage in Marmara Ereğlisi
(Yümün and Kam, 2021)
Nitrogen (N) and Phosphorus (P) fertilizers used in agriculture reach the seas
by surface or underground transmission and reduce the pH value of the seas
and increase the electrical conductivity. This situation may contribute to the
stress of algae and other phytoplankton living in the seas. Sudden warming
of sea water, variation in the food chain, increase in the population of living
things, competitive conditions are also among the conditions required for the
production of phytoplankton mucilage. Elemental analysis was performed
using ICP-OES method on the water sample taken from the clean area of the
Marmara Sea (S-1) and the water sample from the mucilage contaminated
zone (S-5) and the concentration values of the elements were determined. In
the measurement results, the measurement values of some elements (Mn, Zn,
Al, Cu, As, Pb, Cd, Hg, Mo, Co, Fr, Sb, Bi, Ni) are below the measurement limit.
According to the measurement results, it is understood that the concentrations
of some elements (K, P, Ca, Mg, B, Fe, Zn) are above normal values (Table 3).
