A facile, economical and straightforward hydrothermal strategy was used to prepare highly luminescent nitrogen‐doped carbon quantum dots (N‐CQDs) by using citric acid and urea as the precursors. The as‐prepared N‐CQDs exhibited excellent excitation‐wavelength‐dependent photoluminescence property, high relative fluorescence quantum yield of up to 82.4%, and high selective response to Hg2+ over other examined metal ions in water samples. Under the optimal conditions, the response was linearly proportional to the Hg2+ concentration in the range of 0–250 μM with a detection limit of 1.3 nM. The established N‐CQDs based fluorescent sensor was then successfully applied for label‐free detection of Hg2+ in environmental water samples (tap, lake, and well water). Satisfactory repeatability, reproducibility, recovery results (92.6‐116.8%) are achieved for the determination of Hg2+ in real water samples.

Water scarcity is a growing concern due to rapid urbanization and population growth. This study assesses spring water quality at 20 stations in Giresun province, Türkiye, focusing on potentially toxic elements and physicochemical parameters. The Water Quality Index rated most samples as "excellent" during the rainy season and "good" during the dry season, except at stations 4 (40° 35′ 12″ North/38° 26′ 34″ East) and 19 (40° 44′ 28″ North/38° 06′ 53″ West), indicating "poor" quality. Mean macro-element concentrations (mg/L) were: Ca (34.27), Na (10.36), Mg (8.26), and K (1.48). Mean trace element values (μg/L) were: Al (1093), Zn (110.54), Fe (67.45), Mn (23.03), Cu (9.79), As (3.75), Ni (3.00), Cr (2.84), Pb (2.70), Co (1.93), and Cd (0.76). Health risk assessments showed minimal non-carcinogenic risks, while carcinogenic risk from arsenic slightly exceeded safe limits (CR = 1.75E−04). Higher arsenic concentrations during the rainy season were due to increased recharge, arsenic-laden surface runoff, and human activities. Statistical analyses (PCA, PCC, HCA) suggested that metals and physico-chemical parameters originated from lithogenic, anthropogenic, or mixed sources. Regular monitoring of spring water is recommended to mitigate potential public health risks from waterborne contaminants.
