the influence of long-term mixed organic and inorganic contamination on soil microbial activity, community structure and genetic diversity was investigated in soil samples from a coke oven plant located in upper silesia, poland. the tested soils were heavily contaminated with polycyclic aromatic hydrocarbons (pahs) and heavy metals. the microbial communities were characterized using the phospho...

To the Editor—Multidrug-resistant organisms (MDROs) have recently caused infection outbreaks with increased morbidity and mortality. Colonization of the inanimate hospital environment and intestines may contribute to the increased prevalence of MDROs. To prevent the spread of MDROs in the intensive care unit (ICU), the correlation between colonization of MDROs and the length of patient hospital...

Rainwater harvesting (RWH) systems have been the source of domestic water for many years and still becoming essential in communities developing countries. However, due to various reasons, there are several sources contamination rainwater cistern systems. Dissolved chemicals from roofing, storage, conveyance materials, together with suspended particulate matter airborne, examples contamination. ...

UNLABELLED BACKGROUND The objective of this study was to examine the potential environmental risk of tailings resulted after precious and base metal ores processing, stored in seven impoundments located in the Aries river basin, Romania. The tailings were characterized by mineralogical and elemental composition, contamination indices, acid rock drainage generation potential and water leachab...

We use data from 58 strong lensing events surveyed by the Sloan Lens ACS Survey to estimate the projected galaxy mass inside their Einstein radii by two independent methods: stellar dynamics and strong gravitational lensing. Four models are examined testing the galaxy-lens density profile and a possible line-of-sigh (l.o.s.) mass contamination. We test a fixed isothermal profile and a power-law...

Toxic trace metals concentrations in soil exert a decisive impact on soil quality and its use in food production particularly in an industrial area. An attempt is made here to study toxic metals such as Cr, Cu, Ni, Pb, Zn, including Ba, Co and V in representative soil samples from Patancheru industrial area near Hyderabad, Andhra Pradesh. It is a known polluted area and is one of the most conta...
