human health risk assessment, congener specific analysis and spatial distribution pattern of organochlorine pesticides (ocps) through rice crop from selected districts of punjab province, pakistan. | to evaluate the screening level risk assessment of ocps in rice (oryza sativa l.) straw (n=20) and rice grains (n=20), samples were collected from different districts of punjab province, pakistan. ∑ocps' levels (ng g(-1)) in rice straw and grains ranged from 3.63 to 39.40, 2.72 to 49.89, respectively. ddts were found predominant over the other detected ocp isomers followed by hch and heptachlor. results of one way anova reflected no significant difference for ocps' levels among sampling sites, e ... | 2015 | 25553549 |
polychlorinated biphenyl (pcbs) in rice grains and straw; risk surveillance, congener specific analysis, distribution and source apportionment from selected districts of punjab province, pakistan. | the current study presents health risk surveillance by investigating the levels of polychlorinated biphenyls (pcbs) in rice (oryza sativa l.) grains and rice straw. samples were collected from four districts (okara, sahiwal, lahore and sheikhpura) of punjab province, pakistan for congener specific analysis of pcbs, and to observe the spatial distribution pattern and point sources. level of σ30 pcb (ng g(-1)) in rice grains and rice straw ranged from 4.31 to 29.68 and 6.11-25.35, respectively. te ... | 2016 | 26613515 |
economical and environmental implications of solid waste compost applications to agricultural fields in punjab, pakistan. | application of municipal solid waste compost (mswc) to agricultural soils is becoming an increasingly important global practice to enhance and sustain soil organic matter (som) and fertility levels. potential risks associated with heavy metals and phosphorus accumulations in surface soils may be minimized with integrated nutrient management strategies that utilize mswc together with mineral fertilizers. to explore the economic feasibility of mswc applications, nutrient management plans were deve ... | 2009 | 19501499 |
effect of saline soil on grain quality of rices differing in salinity tolerance. | four varieties of rice, differing in salinity tolerance and grown in saline soil (electrical conductivity 5-6 ds/m) at sadhoke, punjab, pakistan, had lighter grain and higher na content than control samples. grains of three out of the four rices grown on saline soils had higher brown rice protein (higher nutritional value), less translucent grain, lower starch and amylose content, and lower k than their control samples, but these differences were not related to salinity tolerance. alkali spreadi ... | 1990 | 2345732 |
