The subsidence pond is an important water resource for coal mining areas in China. In order to take full advantage of the pond, a floating photovoltaic cover or pillaring were installed on surface Huainan field. Different systems (floating/pilling cover) equipped may affect quality; thus, assessing metals with solar system great importance environment control. this research, samples collected f...

1. Haemoglobin production was measured for two populations of Daphnia putex, one from a temporary pond (GR Pond) and one from a permanent pond (Rash Pond). Surface water in Rash Pond remains high in oxygen, while by late summer very Uttle oxygen remains in GR Pond. Haemoglobin synthesis was induced in the laboratory by artificial oxygen deficiency. 2. Reproductive state influenced the level of ...

PCR-denaturing gradient gel electrophoresis (DGGE) and canonical correspondence analysis (CCA) were used to explore the relationship between eukaryotic plankton community succession and environmental factors in two aquaculture pond models with gibel carp Carassius auratus gibelio. The main culture species of pond 1 were gibel carp and grass carp, and the combined density was 46224 fingerling/ha...

In this research, the quality of wastewater discharged into environment has been investigated. The effluent from solar desalination pond contains large amounts TDS (3.68 grams per liter) and TH (6.50 liter). Since use filter is not economical in case, three types commercial coagulants such as aluminum sulfate, ferric chloride sulfide have used study. main parameters effectiveness inorganic coag...
