Fish assemblage was investigated during the study of longitudinal profile of the Ehania River Basin in south-eastern Côte d’Ivoire. This area is subjected to intense human activities with many plantations (palm tree, banana, pineapple, coffee, rubber and cocoa). Samples were collected, with gillnets of different mesh sizes, through 6 sampling surveys during dry and rainy seasons from February ...

background dust events are common air pollution events in parts of the world in arid, semiarid, or desert areas. during the last years, air quality of kerman city has been deteriorated due to urban and industrial development as well as population growth. objective the aim of this study was to evaluate the dust fall events in kerman city. material and methods the british jar test assembly method...

A swab-sampling method was developed for cleaning validation of a residual active pharmaceutical ingredient in samples collected after cleaning the sampling suite. A summary of the strategies and results of the method development is presented. The developed extraction method produced an acceptable level of recovery and precision. ross contamination with active ingredients is a real concern. The...

The study comparatively assessed the impacts of farm activities on the abundance and diversity of soil arthropods and soil physico-chemical parameters of the Practical Year Training Programme (PYTP) farmlands, University of Ibadan, South Western Nigeria. Soil arthropods were collected from September, 2010 to February, 2011 in five sampling sites of PYTP farmlands using Berlese Tullgren Extracti...

Since 1972, the UNESCO "World Heritage Convention" offers an international canvas for conservation and management that targets areas of high cultural and environmental significance. To support the designation of areas within the 36.000 km(2) of New Caledonia coral reefs and lagoons as a World Heritage Site, the natural value and diversity of the proposed zones needed to be demonstrated. To exha...

Article history: Received 15 February 2005 Received in revised form 9 April 2005 Accepted 12 April 2006 This study demonstrated prediction of breeding success of Black-tailed Gulls in relation to the selected environmental factors through evaluation of relative importance in determining breeding success. The data were obtained from the 258 selected and 120 non-selected sites for breeding of the...

Strategies for sampling shallow soils at hazardous waste sites are employed primarily to evaluate levels and distributions of contamination. The ensuing analyses of potential public health impacts are therefore dependent on the sampling design rather than having the sampling design based on the data needs for evaluating potential public health impacts of shallow soil contamination. We define a ...

Fungi are one important group of eukaryotic microorganisms in a diverse range of ecosystems, but their diversity in groundwater ecosystems is largely unknown. We used DNA-based pyro-tag sequencing of the fungal internal transcribed spacer (ITS) rDNA gene to investigate the presence and community structure of fungi at different sampling sites of two superimposed limestone aquifers ranging from 8...

Abstract Background Anemia is one of the most common abnormalities in pediatric medicine. Considerable differences are seen in the peripheral blood indices of infants in developing countries. The aim of this study was to determine and compared blood hemoglobin concentration in three sites of sampling in neonate. Materials and Methods 1600 term and preterm new infant in three sites of sampli...

OBJECTIVES This study evaluates personal exposure to respirable inorganic and organic fibers during normal human lifetimes and assesses the order of magnitude of the contribution of inorganic fibers other than asbestos to total fiber exposure from man-made and natural sources. METHODS Four groups (suburban schoolchildren, rural retired persons, office workers, and taxi drivers), with five per...
