Water and sediment samples have been collected from five different stations, located along Djendjen River between February and June, 2016 so that the concentrations of Cd, Ni, Zn, and Cu could be determined. The extent of the sediment pollution has been assessed, using the multiple pollution indices, namely Contamination Factor (CF), Pollution Load Index (PLI), and the geoaccumulation index (Ig...

background cereal products are susceptible to mould damage during pre- and post-harvesting stages of the production. the regional specificity of golestan province in the northern region of of iran, with its high temperature and high relative humidity, acts as a leading factor for the growth of aflatoxin-producing fungi. it is well known that contamination of starch-based ingredients with mycoto...

Background The Sediment Quality Objectives (SQO) indirect effects assessment determines whether sediments meet California’s narrative SQO for human health: Pollutants shall not be present in sediments at levels that will bioaccumulate in aquatic life to levels that are harmful to human health. This program determines whether sediment contamination at a site results in an unacceptable health ris...

Water quality data collection in shallow water areas can be a challenging task. Obstacles encountered in such environments include difficulty in covering large territories and the presence of inaccessible areas due to a variety of reasons such as a soft bottom or contamination. There is also a high probability of disturbing the test area while placing the sensors. This paper describes a NASA-fu...

background: existence of bacterial host cell dna contamination in biopharmaceutical products is a potential risk factor for patients receiving these drugs. hence, the quantity of contamination must be controlled under the regulatory standards. although different methods such as hybridization assays have been employed to determine dna impurities, these methods are labor, intensive and rather exp...

OBJECTIVES This study examined the spatial distribution and the extent of soil contamination by heavy metals resulting from primitive, unconventional informal electronic waste recycling in the Agbogbloshie e-waste processing site (AEPS) in Ghana. METHODS A total of 132 samples were collected at 100 m intervals, with a handheld global position system used in taking the location data of the soi...

The emotion of disgust, with feelings of revulsion and behavioral withdrawal, make it a prime emotion to aid in the avoidance of sources of contamination, including sources of potential infectious disease. We tested the theory that living in a region with a historically high prevalence of infectious diseases would promote higher levels of disgust and contamination sensitivity as a protective me...
