Heavy metal contamination in lakes caused by the rapid industrialization and urbanization is a serious problem. In this study, 12 heavy metals were systematically surveyed aquatic environment organisms of Dianchi Lake. Results showed that pollutions surface water exhibited decreasing order Ba > Fe Zn Mn As Ni Cr Cu Pb Cd Co, equipped consistency spatial distribution, seriously contaminat...

Nutrient criteria provide the numeric basis for lake eutrophication management. However, there are two obstacles that can hinder effective application of nutrient criteria, including 1) although total phosphorus (TP) and nitrogen (TN) might co-limit phytoplankton biomass in eutrophic lakes, their often developed independently; 2) linkage between percentile-based compliance assessment method chl...

Bacteria play an important role in the decomposition and cycling of a variety of compounds in freshwater aquatic environments, particularly nutrient-rich eutrophic lakes. A unique Chinese eutrophic lake--Dianchi--was selected for study because it has two separate and distinct basins, Caohai with higher organic carbon levels and Waihai with lower organic carbon levels. Sediment bacterial communi...

There are many rivers flowing from complex paths into Lake Dianchi. At present, there is a lack of inflow and water quality monitoring data for some rivers, resulting in limited accuracy statistical results regarding volume external loading estimations. In this study, we used DYRESM to estimate the entering Waihai Dianchi 2007 2019 without historical hydrological observation data. Then, combine...

Cyanobacterial blooms represent a significant environmental problem, threatening aquatic ecosystems worldwide. Caused by the eutrophication of water bodies and global climate change, these have altered freshwater worldwide during recent decades. Although cyanobacterial are typically caused blue-green cyanobacteria, which derive their color from phycocyanin pigment, other pigmented been frequent...

Qinghai-Tibet Plateau (QTP) Lake Region has largest abundance and size distribution of lakes in China. Being relatively away from major human activities, the water quality these not attracted concerns past. However, dramatic climate change intensified anthropogenic activities over past 30 years have exerted multiple pressures on environment lakes, resulting elevated nutrient concentrations fres...
