How to increase the efficiency of chemical flushing and decrease the remediation expenses of contaminated soils are two key scientific and technological issues to be solved. Joint chemical flushing was tested and compared with the water-flushing. The joint acid-flushing could effectively remove petroleum hydrocarbons in contaminated aquorizem and the dosage of washing powder as a flushing agent...

Simulated furcation perforations were repaired with and without blood contamination utilizing tooth-colored mineral trioxide aggregrate (MTA) mixed with either MTA liquid (sterile water), lidocaine, or saline. Samples underwent Instron testing at either 24 or 72 hours and at 7 days. Data were analyzed using a 3-way ANOVA and post-hoc testing using Turkey's true test for significance. All of the...

In July 2000, an outbreak of gastroenteritis occurred at a tourist resort in the Gulf of Taranto in southern Italy. Illness in 344 people, 69 of whom were staff members, met the case definition. Norwalk-like virus (NLV) was found in 22 of 28 stool specimens tested. The source of illness was likely contaminated drinking water, as environmental inspection identified a breakdown in the resort wate...

In the present study, bacteriological quality of 187 different mineral water bottle brands marketed in Karachi was analyzed from September 2009 to June 2010. All the collected samples were analyzed for the presence of coliform bacteria, fecal coliform bacteria, E. coli, fecal entrococci, P. aeruginosa and total viable plate count (TVPC). Alarmingly, 67 (36%) of these samples did not comply with...

An outbreak of hepatitis was reported from a military unit. An investigation to determine the type and the cause of outbreak revealed that the maximum number of cases occurred in a barrack which shared a common water supply contaminated from an overflow from a septic tank. Another barrack which had separate supply from the same source was unaffected. Seromarker study in 8 cases showed immunity ...

Submit Manuscript | http://medcraveonline.com is typically transmitted through direct contact of oral or nasal mucosa, with contaminated urine or water, and dogs are at risk of infection from drinking contaminated water [1,2]. Dogs play an important role as potential indicators of areas with high endemicity for leptospirosis. Thus, recognizing and preventing canine leptospirosis has implication...

There is a persistent emergence of human health and ecological assessment issues associated with perchlorate (ClO4-) and it is observed that even at extremely low concentration causes serious health implications on human being. It is used in rocket fuels, fireworks, explosives and other applications were an energetic oxidant is required. The existence of ClO4as a contaminant in effluent water, ...

Sprinkler irrigation is a common farming practice in those states where the semi-arid climate and lack of sufficient rainfall during critical growing periods necessitate the use of supplemental water. The source of most irrigation water is groundwater which can be contaminated with volatile organic compounds (VOCs). Since the groundwater may be the primary or only source of drinking water for a...

Approximately 5.5 x 109 g (4.0 x 105) of mercury was discharged into the Carson River Drainage Basin of west-central Nevada during processing of the gold- and silver-rich Comstock ore in the late 1800s. For the past 13 decades, mercury has been redistributed throughout 500 km2 of the basin, and concentrations are some of the highest reported values in North America. This article documents the c...
