Background and Objectives: Perchlorate, as an emerging contaminant, has attracted notice of the most individuals and organizations. Presence of perchlorate in the human body can lead to inappropriate regulation of metabolism in adults. Moreover, due to inhibition of iodide uptake in the thyroid gland, it causes neurological and behavioral problems in infants and children. United States Environm...

The aim of this study was to monitor the sediment, soil and surface water contamination with selected popular triketone herbicides (mesotrione (MES) and sulcotrione(SUL)), atrazine (ATR) classified as a possible carcinogen and endocrine disrupting chemical, as well as their degradation products, in Silesia (Poland). Seventeen sediment samples, 24 soil samples, and 64 surface water samples colle...

To learn more about salivirus/klassevirus, we tested feces of children with diarrhea in China during 2008-2009. We isolated the virus from 9/216 diarrhea samples and 0/96 control samples. The nearly full polyprotein of 1 isolate, SH1, showed 95% identity with a salivirus from Nigeria, indicating widespread distribution and association with diarrhea.

Digging by gophers disturbs near-surface soils, deposits sediment in mounds and “eskers” in non-uniform surface patterns, and affects surface penetrability of soils at alpine treeline. Soil samples were collected and soil compaction was measured at three sites in the Culebra Range of the Sangre de Cristo Mountains in southern Colorado, to determine the effects of gophers on surface compaction a...

evaluation of changes present in soil and water resources due to operation implement of floodwater spreading is necessary to assess their positive or negative resultant effect. rate of the internal sediment to diversion spreader channels, surface sedimentation and aggregation of the spreading field depth are most important effective attributes on the yield of floodwater spreading systems. these...

numerous ecological risk assessment methodologies have been developed over the last twenty years around the world for evaluating effects of pollutant on receptors such as different wildlife species. but so far such methods have only rarely been used to determine potential ecological risks in iran. therefore in this study we used one of these methodologies (eco-ssls) to determine ecological risk...

Forests are an important economic source for human and have key role in nutrient cycle, hydrology and ecosystem performance, any interference in this vital ecosystem causes to damage to forests. Mechanical logging and road construction in forest areas have led to much soil compaction. Soil physical and chemical properties were studied in parts of road and non-road in the Darabkola forest of Ira...

Forty-five soil samples of surface (0–15 cm) and subsurface (15–30 cm) soils from agricultural sites of Delhi, Haryana, Haridwar, Uttar Pradesh (UP) and around the hexachlorocyclohexane (HCH) manufacturing plant of IPL (Indian Pesticide Limited) and nine samples of different commercial brands of drinking water from markets in Delhi were analysed for the presence of residues of HCH isomers. Thir...

Twentyfour surface soil samples (0-30 cm) collected from salt affected area of Vasantdada Sugarcane Research and Development farm Manjari(Bkk.), Pune, Maharashtra (India) were studied for the Cu, Zn, Fe and Mn status in relation to important soil factors. All the soil samples had adequate amount of Cu, Zn, Fe and Mn. Iron and Maganese are significantly positively correlated with organic carbon,...
