A B S T R A C TIn this study, the water quality and heavy metal pollution status of Riva Stream which is related to Ö merli Dam Lake, one of the water resources of Istanbul (Turkey), was determined. For this purpose, some physicochemical parameters, phytoplankton compositions, some nutrient, and heavy metal concentrations in the surface water of Riva Stream were investigated. Samples were collected at six sampling sites in the course of the stream in February 2012 and May 2012. A total of 19 taxa, belonging to five divisions, were identified. The phytoplankton density varied from 47 to 264 ind./cm 3 ; chlorophyll-a contents varied between 1.52 and 1.83 mg/m 3 . Measured concentrations of heavy metals and nutrients showed difference related to sampling points. As a result of measurements, the lowest and highest heavy metal and mineral nutrient concentrations of measured water samples were as follows: Al (617.40-1094.16 μg/L), B (1010.40-5736.00 μg/L), Ca (1015.80-1925.40 mg/L), Cd (1.45-5.22 μg/L), Cr (61.26-164.16 μg/L), Cu (35.04-372.66 μg/L), Fe (28.50-369.06 μg/L), K (179.10-1314.60 mg/L), Mg (202.68-1755.60 mg/L), Na (669.00-1553.40 mg/L), Ni (40.62-269.70 μg/L), Pb (6.48-76.86 μg/L), and Zn (429.18-990.60 μg/L).It was observed that Riva Stream is highly polluted by some heavy metals, and a number of heavy metal resistant/tolerant phytoplankton species are present in the stream. Pearson's correlation and Spearman rank correlation analyses were applied to examine the relationship between Al, B,

“…Pearson's correlation coefficient between two variables is defined as the covariance of the two variables divided by the product of their standard deviations [27]. It must be pointed out that the Pearson correlation coefficient does not determine causalities, nor ascertain the presence of nonlinear relations, however, only linear relationship [28]. The Pearson correlation coefficient matrix of the dataset and the significance values of the correlations are presented in Table 6.…”

Abstract. Many cities, especially larger metropolises, parks are very important recreational areas where people usually have closer contact with flora. Therefore, the pollution level in the parks can have a greater effect on human health. Heavy metals are ubiquitous with the environment, as a result of both natural and anthropogenic activities, and humans are exposed to them through various pathways. Essentially, these areas are assumed to be less exposed to routine contaminants, but especially in metropolises, this assumption could prove false considering these areas are stuck within the confines of a city full of pollutant activity such as intense traffic. In this study; the relationships between heavy metal pollution levels (Cd, Cr, Cu, Ni, Pb, Zn) and the pH and electrical conductivity (EC) of soil samples were investigated from the parks on the Asian side of Istanbul. For this purpose, the most frequently visited 16 parks were selected as sampling sites. In the second part of the study, linear correlation is used for the data analysis.
