Abstract: The aim of present study was is to create awareness about the current status of irrigation water (ground / water) quality and usability for cultivation. The irrigation system of study area is devoid of artificial system and receives insufficient precipitation. Levels of selected heavy metals such as Cd, Cr, Cu, Fe, Ni, Zn, Mn, Hg and Pb were estimated in water samples used for irrigation. A majority of the samples collected from the catchment area of Malir River, sub-urban eastern area of Karachi (near the sewage and industrial drain). Almost all the samples were are within WHO irrigation (water) standards of year 2004 (except for TDS). Iron showed a negative correlation with pH, TDS and all detected metal ions, where as positive correlation exist between Mn and Zn. Heavy metal concentrations were found to be elevated ions in almost all samples of vegetables, fruits and fodders irrigated in the study area particularly concentrations of Mn, Pb, Hg and Zn, which are well bey...

A composicao quimica e as propriedades morfologicas das fibras, de materiais lignocelulosicos, sao fatores-chave que afetam a eficiencia da producao de biocombustiveis durante os processos de conversao. Assim, a composicao quimica de plantas de tabaco foi examinada para avaliar seu potencial para producao de bioetanol. Apos hidrolise de tecidos (xilema, medula, folhas e raizes) com acido trifluoroacetico e acido sulfurico, os hidrolisados foram analisados atraves de sua composicao de carboidratos utilizando cromatografia de troca ionica (HPAE-PAD). Na haste de tabaco (tecido do xilema), os teores de carboidratos e lignina foram 62,4% e 20,8% de materia seca (MS), respectivamente. Esses valores sao muito proximos dos encontrados em madeira (eucalipto) e em bagaco de cana. As propriedades morfologicas das fibras do tecido xilematico e cortes histologicos efetuados na base do caule foram tambem avaliados e os resultados mostraram que as suas caracteristicas sao semelhantes aos de bioma...
