background: in the current study,the hazard quotient, the hazard index (hi) and spatial variations of fe,mn,cu and cr in drinking water sources of andimesk-shush, khuzestan province, southern iranaquifer were assessed. methods: we compared theconcentrations of aforementioned heavy metals in wells and springs inandimeshk and shush regions. the non-carcinogenic risk assessment of heavy metals was...
Abstract One method of probing new physics beyond the Standard Model is to check correlation among higher-dimensional operators in effective field theory. We examine strong between processes and tq , which both depend on same three operators. The indicates that, according data \sigma_{tHq} = \big[106.8 \pm 64.8\big]\; {\rm fb} significantly below current upper li...
A 2328-membered library of 2,3,4-trisubstituted tetrahydroquinolines was produced using a combination of solution- and solid-phase synthesis techniques. A tetrahydroquinoline (THQ) scaffold was prepared via an asymmetric Povarov reaction using cooperative catalysis to generate three contiguous stereogenic centers. A matrix of 4 stereoisomers of the THQ scaffold was prepared to enable the develo...
Groundwater resources make up an important portion of potable and irrigation water in Iran, making it important to monitor toxic elements of pollutants in these resources in order to protect the inhabitants' health. The current study has been carried out to assess the health risks, caused by trivalent inorganic arsenic-polluted groundwater in Qaleeh Shahin Plain, an important agricultural regio...
Objective: The purpose of this study was to look into the concentration heavy element Cadmium and its health risks in cheese samples available Iraqi markets. Methods: 72 random six country groups (15 Iran, 9 Iraq, Egypt, 15 Turkey, Hungary, Saudi Arabia) markets were collected analyzed using an atomic absorption spectrophotometer, Shimadzu model AA7000, USA. Results: highest average Cd metal le...
Background and Aims: Heavy metals in atmospheric dust can enter the human body through ingestion, respiration and skin contact and cause various diseases. The aim of this study was to determine the concentration of lead, a heavy metal, in atmospheric dust and assess its health risk during the period between winter of 1397 and the fall of 1398 in regions 9, 10, 11 and 12 of Tehran Municipality, ...
the aim of this study was to determine the concentration of copper and hazard quotient (hq) in muscle of the carp aquaculture fishes (common carp) (cyprinus carpio), grass carp (ctenopharyngodon idella), big head carp (aristichthys nobilis) and silver carp (hypophthalmichthys molitrix)] in khuzestan province. 108 pieces farmed fish sampled was prepared from the azadegan warm water fish culture ...
Background and aims: Recently, there is an increasing concern about the quality of breath air in cabins of public transportation system. Present study measured the driver’s occupational exposure of BTEX as the most important and toxic group of VOCs in cabins of Tehran bus rapid transit (BRT) system. Methods: NIOSH 1501 was used for sampling and analyzing. Samples were extracted by CS2 and anal...
