Journal ArticleDOI
Development of a relative risk model for evaluating ecological risk of water environment in the Haihe River Basin estuary area
TL;DR: The results showed that there were two low risk regions, one medium risk region and two high risk regions in the HRBE, and urbanization was the biggest source, the second was shipping and the third was industry, and habitat destruction was the largest stressor with the risk scores.
Journal ArticleDOI
Ecological risk assessment of water environment for Luanhe River Basin based on relative risk model.
TL;DR: The relative risk model (RRM) was applied in regional ecological risk assessments successfully and showed water deterioration and ecological service values damaged were facing the biggest risk pressure, and secondly was biodiversity decreased and landscape fragmentation.
Journal ArticleDOI
Distribution and potential ecological risk of heavy metals in the typical eco-units of Haihe River Basin.
TL;DR: In this article, the distribution and characteristics of seven heavy metals in sediments located in the typical ecological units (eco-units) (e.g., rivers, lakes, and estuaries) of Haihe River Basin were analyzed.
Journal ArticleDOI
Pollution characteristics, ecological risk and sources of polycyclic aromatic hydrocarbons (PAHs) in surface sediment from Tuhai-Majia River system, China
TL;DR: In this article, the authors used the risk quotient (RQ) to assess the ecological risk of polycyclic aromatic hydrocarbons (PAHs) in surface sediment samples collected from 9 sites of the Tuhai-Majia River system.
Journal ArticleDOI
No-linear dynamics of lake ecosystem in responding to changes of nutrient regimes and climate factors: Case study on Dianchi and Erhai lakes, China
TL;DR: In this article, the authors analyzed over 20 years monitoring data in two lakes with similar geology but different nutrient levels by using statistical and modeling methods, and revealed the impact of UEAP on lake algae dynamics and the driving factors of change in UEAP changes.
