Abstract There are numerous industry byproducts that have negative environmental impacts. Pond ash accumulated from coal power plants is one such byproduct creates major and social issues, especially with regard to decommissioning a plant. Using pond in the block manufacturing process promising solution proposed by Nu-Rock. This research study evaluated economic impact throughout life cycle of ...

Archaeal 16S rRNA gene compositions and environmental factors of four distinct solfataric acidic hot springs in Kirishima, Japan were compared. The four ponds were selected by differences of temperature and total dissolved elemental concentration as follows: (1) Pond-A: 93°C and 1679 mg L(-1), (2) Pond-B: 66°C and 2248 mg L(-1), (3) Pond-C: 88°C and 198 mg L(-1), and (4) Pond-D: 67°C and 340 mg...

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...

One of the indexes of stabilization pond is the presence of coliform bacteria in water and wastewater. This study aimed to determine the effect of solar light on coliform variations in stabilization pond. In this experimental study, the effect of light, pH (<7, 7.1–8, 8.1–9), and temperature (10 ºC and 30 ºC) on facultative stabilization pond was studied for six months. The sampling was accompl...

Concentrations of 6 different heavy metals and total polycyclic aromatic hydrocarbons (PAHs) were determined in stormwater runoff and in the pond water of two Danish wet detention ponds. The pond water samples were analyzed for toxic effects, using the algae Selenastrum capricornutum as a test organism. Stormwater and pond water from a catchment with light industry showed high levels of heavy m...

Temporary-pond species can be expected to use environmental cues to predict the onset of adverse conditions, while permanent-pond species may be insensitive to such cues. Temperature is such a potential cue in temporary waterbodies, as it fluctuates more widely with decreasing pond size than in deeper permanent ponds. We compared the temperatureinduced response of a permanent-pond and a tempora...
