This work applied new investigative techniques to assess the locations, distributions, and associations of polycyclic aromatic hydrocarbons (PAHs) in dredged harbor sediment. Dredged materials from the Milwaukee Confined Disposal Facility were collected and homogenized to provide sufficient sample for four month bioslurry treatment testing and for PAH analyses on various size and density fracti...

polycyclic aromatic hydrocarbons are a class of potentially hazardous chemicals of environmental and health concern. pahs are one of the most prevalent groups of contaminants found in soil. biodegradation of complex hydrocarbon usually requires the cooperation of more than single specie. in this research biotreatment of pah (phenanthrene) was studied in a solid-phase reactor using indigenous ba...

The survival rate of Penaeus monodon was monitored for a decade (2010-2019) in two shrimp culture ponds at Chemaguri located Sagar Island the Indian Sundarbans delta complex. exhibited significant variations terms cultured species, which is attributed to nitrate, phosphate, and dissolved oxygen. root cause such difference related variation stocking density species (10 PL20/m2 pond 1 25 2) resul...

This study compares the removal of a mixture of benzene, toluene, ethylbenzene, and all three xylene isomers (BTEX) in mesophilic and thermophilic (50 degrees C) bioreactors. In the mesophilic reactor fungi became dominant after long-term operation, while bacteria dominated in the thermophilic unit. Microbial acclimation was achieved by exposing the biofilters to initial BTEX loads of 2-15 g m(...

The treatment of electroplating industrial effluent by coconut husk was carried out by analyzing the physico-chemical parameters of the effluent such as pH, salinity, calcium, magnesium, phosphates, nitrates, BOD3 30C̊ and total solids using standard methods. The efficiency of coconut husk was tested by using it in different quantities such as 25, 50, 75 and 100 grams for five days. As a result,...
