The Mighan playa/lake is characterized as a closed catchment. In the recent years, the rapid industrialization and urbanization has resulted in a pollution area in the city of Arak. In this work, we focus on six regions around the playa/lake to study the distribution of heavy metals in the waters and their contamination risk. A total of 32 water samples are analyzed to determine the conta...

Cement dust deposition on soil has been implicated in the heavy metal (HM) contamination of soil, leading to adverse effects on plants and humans. This study assessed the impact of cement dust deposition on the HM content of the soil samples in the vicinity of a cement factory and its implication on the public health of the host community. Topsoil samples were collected at varying distances and...

Sulak alan ekosistemleri çok sayıda fauna ve flora türüne yaşam ortamı sunan, aynı zamanda insanların faydalandığı önemli doğal kaynak değerleridir. Son yıllarda artan antropojenik etkiler sulak alanlarda PTE kaynaklı ekolojik bozulmaya buralardan çeşitli yollarla faydalanan insanlar üzerinde sağlık risklerine neden olmaktadır. Bu nedenle, bozulma riski analizleri yapmak için analitik metotlar ...

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...

Hong Kong played a pivotal role in the international spread of the Severe Acute Respiratory Syndrome (SARS): a doctor who spent the night of 21-22 February 2003 at Hotel 'M' was identified as the index case for four national and international clusters of SARS. In parallel to the international collaborative study led by WHO and United States, a retrospective study on the cohort of German persons...

there are many potential risks to human health from heavy metal contamination of vegetables resulting from wastewater irrigated sites. this study was carried out to assess the concentration of chromium (cr) and the risk to human health by chromium through the intake of locally grown vegetables collected from wastewater irrigated agricultural fields. twenty-seven samples of 9 (nine) different ty...

SNP allelic copy number data provides intensity measurements for the two different alleles separately. We present a method that estimates the number of copies of each allele at each SNP position, using a continuous-index hidden Markov model. The method is especially suited for cancer data, since it includes the fraction of normal tissue contamination, often present when studying data from cance...

Background: The Ural region is highlighted among other Russian regions for its unfavorable radiation situation and complexity of the overall environmental situation. The source of man-made radioactive contamination is the work of the "Mayak" Production Association. A significant radioactive contamination has happened as a result of several radiation incidents in the early period ...
