EXECUTIVE SUMMARY This study of mercury contamination in Newark Bay sediments was initiated from a broader study of mercury sources and material balance in the New York-New Jersey Harbor, conducted for the New York Academy of Sciences' Harbor Consortium by Themelis and Gregory (2001). The author of this report concluded that a more in-depth study should be conducted on a smaller area within the...

The need for assessment of aquatic ecosystem contamination and of its impact on water dwelling organisms was developed in response to rising aquatic environmental pollution. In this field study, liver enzymes of phase I and phase II of xenobiotic transformation, namely cytochrome P450, ethoxyresorufin-O-deethylase, glutathione-S-transferase and tripeptide glutathione were used to assess the con...

The term “mycotoxin” is generally associated with secondary metabolic toxic products of filamentous fungi to which humans and animals can be exposed, most often through ingestion. This exposure can result in a range of toxicities (acute to chronic), and a spectrum of effects (mild to severe) including carcinogenicity and death. The history of mycotoxicoses has been long and dramatic, including ...

Background Despite the avoidance of allergen-containing products by allergic individuals, a risk of allergic reaction to food allergen still remains. These contaminations may result from the shared use of processing equipment in the food industry, and are not always identified. It is therefore important to select a representative food sample to analyse food contamination and to further assess r...

Methods Patients requiring pre-hospital intubation in a physician– led pre-hospital trauma service over 16 months were included. Intubation success rate, misplaced tracheal tube rate, Cormack and Lehane grade and the presence and nature of gross airway contamination were recorded at laryngoscopy. Tube placement was verified with carbon dioxide detection and chest x-ray. After visual assessment ...

In this paper, lumped-parameter models (LPMs) were developed and utilized to simulate nitrate concentration in the groundwater of Gaza City and Jabalia Camp (GCJC) in the Gaza Coastal Aquifer (GCA) in Palestine. In the GCJC area, nitrate levels exceed the maximum contaminant level (MCL) of 10 mg/L NO3-N (45 mg/L NO3) in many wells. Elevated nitrate concentrations in the groundwater of GCJC area...

The present study utilizes multiple methods to examine the relationship between disgust and contamination-related obsessive-compulsive disorder (OCD) symptoms in an analogue sample. Questionnaire findings revealed that participants with high OCD contamination concerns showed stronger disgust sensitivity than did participants with low OCD contamination symptoms after controlling for negative aff...

The disposal of municipal solid waste into the landfills has been recognized as the major source of soil, surface water and groundwater contamination. Municipal solid waste disposal site for the city of Ludhiana, in Punjab, India, has become an overflowing landfill because of the indiscriminate dumping of solid waste at the site. The leachate produced by landfilling site contains a large amount...

BACKGROUND In the sub-urban areas of Kampala city, springs are a major source of water for domestic use. Though spring water is considered to be aesthetically acceptable for domestic use, presence of poorly designed pit latrines, poor solid waste management as well as poor and inadequate spring protection, may lead to contamination of spring water with pathogenic bacteria. OBJECTIVES The obje...
