“…However, several studies did not match our above findings [36,37]. Hong et al (2008) showed that the water TN and TP concentrations in the Xingfengjiang Reservoir basin in the dry season were not significantly different from those in the wet season [37]. The inconsistent results may be mainly attributed to the difference among catchments in terms of the land use composition and agricultural types, which strongly affect the outputs of nutrients and heavy metals.…”

“…Another possible reason is that aquatic macrophytes growing in riparian wetlands and shallow water bodies can absorb and accumulate large quantities of contaminants in the wet season [35]. However, several studies did not match our above findings [36,37].

Due to the acceleration of industrialization and urbanization in recent decades, the majority of coastal rivers and estuaries in China have been moderately or severely contaminated by a variety of pollutants. We investigated the spatial and seasonal variations of water nutrients (permanganate index, chemical oxygen demand, biochemical oxygen demand, ammonium, nitrate, total nitrogen, and total phosphorus) and heavy metals (Hg, Pb, Cu, Zn, Se, As, Cd, Cr, Fe, and Mn) in 27 subtropical rivers draining into the South China Sea. Our results indicated that the average concentrations of all water quality parameters except ammonium, total nitrogen, and total phosphorus satisfied the requirements for grade III of the surface water quality standard of China. The concentrations of both nutrients and heavy metals showed a strong spatial variation. Cluster analysis classified the 27 rivers into three spatial clusters corresponding to low, moderate, and high pollution levels. In terms of seasonal variation, the values of chemical oxygen demand and biochemical oxygen demand in wet seasons were significantly lower than those in dry seasons. Multivariate statistical analyses demonstrated that river nutrients might mainly originate from domestic, industrial, and agricultural wastewaters, while heavy metals likely came from industrial activities and natural weathering processes. The findings of this study suggest that for reducing the pollution of subtropical rivers draining into the South China Sea, further efforts should be made to control nitrogen and phosphorus export from catchments.

“…Nitrogen limitation in lakes is recently more often observed and described in the literature (Havens 1995;Hong et al 2008;Pełechata et al 2006;Rekolainen et al 2005;Schindler 2006), although phosphorus has been considered to be commonly the initial nutrient limiting factor for algal growth in lakes (Rekolainen et al 2005;Wetzel 2001). When phosphorus is available in quantities adequate to support metabolism, nitrogen availability can become limiting.…”

Abstract:The objective of the study was to determine the current trophic state of eight selected lakes -Rybiec, Niezabyszewskie, Czarne, Chotkowskie, Obłęże, Jasień Południowy, Jasień Północny, Jeleń -based on Carlson-type indices (TSIs) and, to examine the relationship between the four calculated trophic state indices: TSI(SD), TSI(Chl), TSI(TP) and TSI(TN). Based on these values, it can be claimed that the trophy level of the lakes are within the mesotrophic and eutrophic states. It was observed that the values of the TSI(TP) in the analysed lakes are higher than the values of the indices calculated on the basis of the other variables. Moreover, the differences between the indices for particular lakes, suggest that in none of the analysed lakes is phosphorus a factor which limits algal productivity.
