In the present study, (NH₄)₂S₂O₃ extraction methods were applied to assess bioaccumulation of methylmercury (MeHg) in rice grains, and inorganic mercury (IHg) concentrations in rice leaves were analyzed during the rice growing time to access the bioaccumulation of IHg in rice leaves. The results show that the IHg concentrations in leaves increased in the rice harvest stage, indicating that the limit...
Heterotrophic nitrifying bacteria are attracting increasing interest due to their advantages in treatment of wastewater with high nitrogen concentration. In this work, four bacterial isolates (WS-1, WS-4, WS-6, and WS-7) with the capability of simultaneous heterotrophic nitrification and aerobic denitrification from soil, sludge, and water by a fast isolation procedure were studied. Isolates WS-1,...
Discovering how to best protect one of the most endangered animals in the world, giant pandas, has always been an important project in ecological studies. Moreover, researching the living environments of giant pandas and how to recover them is one of the most important elements to these studies. In order to more effectively protect the giant pandas and their habitats, we studied the changing of Xiaohegou...
Sawdust is the most popular matrix used in bio-toilets, but the wood resource is scarce in many countries. The aim of our research is to explore the possibility to select cornstalks as alternative matrix in bio-toilets. The experiments were conducted to compare the biodegradation effects of feces mixed with sawdust and cornstalk by monitoring the main physical and chemical parameters. In both tests,...
