Concern about the effects of environmental contaminants on immune function in both humans and wildlife is growing and practically nothing is known about this impact on terrestrial invertebrates, even though they are known to easily accumulate pollutants. We studied the effect of industrial heavy metal contamination on immune defense of a free-living wood ant (Formica aquilonia). To find out whe...

OBJECTIVES The general aim was to assess dietary exposure to selected persistent organic pollutants (POPs) and metals among Eskimo (Inuit) and Chukchi of the Chukotka Peninsula of the Russian Arctic, and to establish recommendations for exposure risk reduction. STUDY DESIGN A cross-sectional evaluation of nutritional patterns of coastal and inland indigenous peoples of the Chukotka Autonomous...

OBJECTIVES To gather enough data from a large scale investigation involving two health authorities, to assess the possible concentrations and routes of exposure and the consequent health implications. To use the data to decide whether a polluted beach should remain open to the public. In Spring 1997, a chemical incident came to light at a beach on the south coast of England when a local residen...

Parameter estimation is the first step in constructing any control chart. Most estimators of mean and dispersion are sensitive to the presence of outliers. The data may be contaminated by outliers either locally or globally. The exciting robust estimators deal only with global contamination. In this paper a robust estimator for dispersion is proposed to reduce the effect of local contamination ...

We investigate the performance of robust estimates of multivariate location under nonstandard data contamination models such as componentwise outliers (i.e., contamination in each variable is independent from the other variables). This model brings up a possible new source of statistical error that we call “propagation of outliers.” This source of error is unusual in the sense that it is genera...

Food borne diseases are considered as the major problems for public health in the world and salmonella serotypes are the most important pathogens causing these types of diseases. Present study was carried out for the isolation of salmonella and determination of their antibiotic sensitivity and serovars from local, industrial and breeder poultry eggs. In this cross-sectional survey, 300 samples ...

A method is described for direct analysis of lead in blood utilizing the carbon rod atomizer. Aliquots of whole blood are analyzed without pre-treatment. Resuits are comparable to those for a similar non-flame technique in which whole blood samples were prediluted with “Triton X-100.” The small sample volumes required and the minimal sample preparation further diminish the possibility of spurio...

Palaeoproterozoic sedimentary basins of north-eastern and central-eastern Australia are host to large amounts of variably deformed and metamorphosed Fe-rich tholeiitic rocks. Emplacement and/or extrusion of the mafic rocks occurred during one or more episodes of crustal thinning relating to a period of regional extension and sedimentation across Palaeoproterozoic northeastern Australia (ca. 173...

Fresh and raw vegetables may play a significant role in transmission of intestinal parasitic infections to humans. Therefore, this study was conducted estimate the level contamination which are consumed Aden governorate, Yemen. This is descriptive analytic cross-sectional six local markets were randomly selected. A total 216 fresh vegetable samples including parsley (Petroselinum sativum), wate...
