In the present article we have studied the radiation effects on the flow of a viscoelastic fluid flow past a spongy plate by considering the viscosity as variable. In order to explore the variable viscosity effects, law of conservation of mass, momentum and energy are flourished. The shooting method is adapted to accomplish the numerical solution of governing equations. The effects of the involved emerging parameters such as Reynolds' model viscosity numbers, Vogel's model viscosity numbers and Prandtl numbers on velocity and temperature profiles are discussed with the help of graphs. The associated physical properties of the flow i.e. the skin friction coefficient and Nusselt numbers are presented graphically for different parameters. The tables for effects of distinct parameters on temperature profile at the wall for Reynolds' model and Vogel's model are given. Impact of various parameters involved on Nusselt number and skin friction are also presented in tables.

The study was conducted in peri-urban areas of Multan, Pakistan for the assessment of heavy metals risk on animal health by the consumption of maize as fodder grown with different types of wastewater/water and its source apportionment. Total 120 samples (wastewater, soil, raw milk, and maize plants) from six sites were collected and analyzed for cadmium, chromium, copper, manganese, nickel and lead contents by inductively coupled plasma-optical emission spectrometry (ICP-OES). The maize plants grown with industrial effluents were highly contaminated and exhibited the highest carcinogenic health risk and the lowest at the canal water irrigation site. The Total Target Health Quotient (TTHQ) values ranged between 27.44 and 80.34 at wastewater, 2.32 and 5.0 at canal water and 3.68 and 7.5 at tube well water irrigation site. The animal population at all studied sites were found expose to carcinogenic health risks. The multivariate statistical analysis indicated that the wastewater/water containing heavy metals and contaminated soil were common sources of maize plants contamination. The consumption of contaminated maize as fodder by lactating animals resulted in milk contamination which indicated that the application of wastewater/water containing heavy metals was causing food chain contamination. The untreated wastewater is not suitable to grow maize to use as fodder for animals.
