| 1 | Source identification, contamination status and health risk assessment of heavy metals from road dusts in Dhaka, Bangladesh显示文摘In this study, concentrations of Cr, Mn, Ni, Cu, Zn, Cd and Pb were determined in road dusts collected from different locations in Dhaka to assess source, contamination status and health risk. Energy-dispersive X-ray fluorescence spectroscopy and energy-dispersive X-ray spectroscopy were used to determine Cr, Mn, Ni, Cu, Zn, Cd and Pb and their mean concentrations were 162.27 ± 29.46, 721.18 ± 180.14, 35.65 ± 12.55, 104.56 ± 128.33, 515.32 ± 321.90,BDL, and 342.82 ± 591.20 mg/kg, respectively. Among the heavy metals, highest concentrations of Cu, Zn and Pb were found at urban sites-7(municipal waste dumping) and 8(medical waste incineration). Highest concentration of Cr followed by Cu and Zn was found at site-5(Tejgaon, urban). Principal component analysis revealed that anthropogenic activities are the potential sources for Cr, Ni, Cu, Zn and Pb while earth crust for Mn. Pollution index and pollution load index results suggested that all the sites were contaminated and/or degraded by Cr, Cu, Zn and Pb except sites-9(urban), 10(sub-urban), 11(rural) while sites-7 and 8(urban) were extremely degraded. For noncarcinogenic health risk, hazard quotient values for dermal were higher compared to that of inhalation/ingestion. Though hazard index values were less than 1 at all the sites, these were at least one order of magnitude higher for children group than that of adult group, thus the children group may face more noncarcinogenic health risk at sites -7 and 8. Values of incremental lifetime cancer risk were from 10to 10showed no carcinogenic health risk by road dusts contaminated with the heavy metals. | Aklima Nargis Ahsan Habib Md Nazrul Islam Kai Chen Md Shafiqul Islam Sarker A N M Al-Razee Wenbin Liu Guorui Liu Minggang Cai | 2022 | Journal of Environmental Sciences2022，34，11： | 3 |
| 2 | In vivo anticancer activity of vanillin semicarbazone显示文摘Objective:To evaluate the anticancer activity of vanillin semicarbazone(VSC) against Ehrlich ascites carcinoma(EAC) cells in Swiss albino mice.Methods:The compound VSC at three doses(5, 7.5 and 10 mg/kg i.p.) was administered into the intraperitoneal cavity of the EAC inoculated mice to observe its efficiency by studying the cell growth inhibition, reduction of tumour weight,enhancement of survival time as well as the changes in depleted hematological parameters. Allsuch parameters were also studied with a known standard drug bleomycin at the dose of 0.3 mg/kg(i.p.).Results:Among the doses studied, 10 mg/kg(i.p.) was found to be quite comparable in potency to that of bleomycin at the dose of 0.3 mg/kg(i.p.). The host toxic effects of VSC was found to be negligible.Conclusions:It can be concluded that VSC can therefore be considered as potent anticancer agent. | Shaikh M Mohsin Ali M Abul Kalam Azad Mele Jesmin Shamim Ahsan M Mijanur Rahman Jahan Ara Khanam M Nazrul Islam Sha M Shahan Shahriar | 2012 | Asian Pacific Journal of Tropical Biomedicine2012，2，6： | 2 |
