Water scarcity is a serious problem in the mega city Karachi. The problem is more pronounced in the slum areas of the city having poor infrastructure and limited facilities. This study presents a quality assessment of piped water supply in the biggest slum area of Asia; the Orangi town. Forty six samples of piped water were collected from different places and examined for bacteriological and ph...

to investigate the effects of regulated deficit irrigation (rdi) on the growth, yield and quality of ‘yali’ pears, field experiments for c (fully watered control), ew [early withholding of irrigation, water stress from pullulation to 25 days after flower bloom (dafb)], mw (mid-growth withholding of irrigation, water stress from 25 dafb to 80 dafb), and lw (late withholding of irrigation, water ...

background: contamination of swimming pools’ water can lead to the transfer of different diseases to humans. the aim of this study was to investigate the quality of water in kerman swimming pools. methods: in this cross-sectional study, sampling from swimming pools was performed before and after swimming, every week. total number of samples collected was 150 samples. samples were investigated i...

background: in this study, the chemical quality of water in some sub-basins of gamasiab river has been investigated for a long term planning of water consuming in the region . methods: the area is about 11 x10 3 km 2 , located in ramadan and kermanshah, the two western regions of iran. in this regard the results of the water samples, which were collected on the outlet of the 13 hydrometrical st...

the purpose of this study is to investigate the performance and efficiency of moringa seeds from different sources on turbidity. a protein analysis test was done for each source; then two different methods of extraction were compared to examine the coagulation activity for the moringa's active ingredient. the results of sodium chloride (naci) extraction in comparison to distilled water ext...

Increased tomato fruit quality in response to increased salinity is well documented (Li, 2000). However, the increased fruit quality is achieved at the expenses of severe yield losses mostly due to reduced fruit size (fresh weight) and increased incidence of physiological disorders such as blossom end rot (BER). The ability to minimize the negative effects of high salinity at the root level, wh...

This paper presents the use of an equilibrium partitioning (EP) method to derive generic quality criteria. Quality criteria for dissolved concentrations in water, total water concentrations and total sediment concentrations were derived from direct-effect data (aquatic toxicity data) and product standard data (human consumption standards). Both sets of data were obtained from physico-chemical a...

On November 13, 1997 the South Carolina Department of Health and Environmental Control Approved regulation R.61-43, Standards for the Permitting of Agricultural Animal Facilities. The State Legislature approved these standards on June 26,1998.
