background: this study was conducted to estimate the level of heavy metals accumulate in vegetables irrigated with contaminated water compared with those irrigated with fresh water in hamadan, west of iran in 2012. methods: sixty samples of different vegetables i.e., parsley, tarragon, sweat basil and leek irrigated with contaminated water and thirty six samples from three different adjacent ar...

H eavy metals, such as cadmium, copper, mercury, and arsenic, are ubiquitous components of the Earth’s crust. Most of these metals are toxic to varying degrees, and life has accordingly evolved ways to deal with them: either by developing mechanisms to detoxify them, or using them for biological functions. As humans began unearthing metals to be turned into consumer products, large amounts of h...

Ductile: Substances that can be drawn into thin wires are called ductile. For example, most of the metals are ductile. Question 2: Why is sodium kept immersed in kerosene oil? Answer: Sodium and potassium are very reactive metals and and combine explosively with air as well as water. Hence, they catch fire if kept in open. Therefore, to prevent accidental fires and accidents, sodium is stored i...

Phosphorescence in ethanol and n-pentane at 77 K of the benzologues 1-8 of furan, thiophene, selenophene and tellurophene has been investigated. The rate constants of both the radiative (A.PT) and non-radiative (A:GT) deactivation of the lowest triplet state correlate linearly with X cl C2 where ck denotes the Hückel AO coefficients in the HOMO of the carbon atoms bound to the hetero-atom and (...

(With the technical assistance of Adelina ()/eda, Alvaro Carstens and Iris Dugarte) H EAVY HOOKWORM INFECTION is sooner or later associated with iron deficiency anemia mainly due to continuous intestinal blood loss. A mean daily intestinal blood loss of 0.031 ± 0.017 ml. per worm and 2.14 ± 1.0 ml. of hlocd per 1,000 ova per gram of feces was found by means of the erythrocyte Cral tagging metho...
