The prevalence of rheumatic diseases in developing countries is largely unknown. Studies which allow comparison data within the contrasting communities Third World and developed world have potential to provide insights into disease aetiologies. current study compared frequency symptoms (point prevalence) amongst 1997 adults distributed evenly between poor rural urban relatively affluent people. Comparisons were also made with similarly but previously derived rates rheumatoid arthritis (RA)...
This paper reports the extended study from a previously-described on As and F contaminated groundwater small village, Kalalanwala, in east Punjab, Pakistan (Farooqi et al., 2007). Of 147 samples investigated, 91% exceeded WHO standard (10 μg/L) for 75% (1.5 mg/L) F-. The highly (max. 2400 F- 22.8 groundwaters were found shallow depths down to 30 m surface. are characterized by high pH 8.8), alkalinity (HCO3- up 1281 mg/L), SO42- 960 Na+ 1058 maximum electric conductivity >4.6 mS/cm.

ABSTRACTThe present study was aimed at assessing drinking water quality regarding arsenic (As) and its impact on health from Mailsi (Punjab), Pakistan. Forty-four groundwater samples were collected two sites, Sargana Mailsi. Arsenic other cations determined by atomic absorption spectrophotometer, whereas the anions either through titration or spectrophotometer. The results revealed that dominant HCO3− Cl−, Ca+2 cation, overall chemistry of area CaMgHCO3− type. concentrations high, ranging 11...
Biosorption efficiency of natural orange peel (NOP) and charred (COP) was examined for the immobilization arsenate (As(V)) in aqueous environments using batch sorption experiments. Sorption experiments were carried out as a function pH, time, initial As(V) concentration biosorbent dose, NOP COP (pretreated with sulfuric acid). Arsenate found to be maximum at pH 6.5, higher removal percentage (98%) by than (68%) 4 g L−1 optimum dose. isotherm data exhibited (60.9 mg g−1) (32.7 g−1). Langmuir...
Finding appropriate adsorbent may improve the quality of drinking water in those regions where arsenic (As) and fluoride (F-) are present geological formations. In this study, we evaluated efficiency potato peel rice husk ash (PPRH-ash)-derived for removal As F from contaminated water. Evaluation was done batch adsorption experiments, effect pH, initial adsorbate concentration, contact time, dose were studied. Characteristics adsorbents analyzed using scanning electron micropcope (SEM)...
Rapid urban sprawl adversely impacts the local climate and ecosystem components. Islamabad, one of South Asia's green environment-friendly capitals, has experienced major Land Use Cover (LULC) changes over past three decades consequently, elevating seasonal annual Surface Temperature (LST) in planned unplanned areas. The focus this study was to quantify fluctuations LULC LST areas using Landsat data Machine Learning algorithms involving Support Vector (SVM) 1990-2020 period. Moreover, hybrid...
South Asians have a significantly higher risk of mortality from coronary heart disease (CHD) compared with the general population in UK. There is lack evidence on attitudes to and knowledge factors for CHD amongst Asians. Such information important provision effective health promotion services.The aim study was identify key issues relating lifestyle aged over 40 years Leicester, UK.A qualitative focus group analysis carried out using randomly selected GP lists attending community centres....
