This Book is compilation of experimental results of total metal concentration and speciation of different food field samples.Concentration of six elements(Cu,Cd,Cr,Ni,Pb,Zn) was determined experimentally after sequential extraction from soils of three crops (Cotton,Oat and Wheat),seven vegetables (Onion,Mustard,Cucumber,Carrot,Tinda,Pea and Garlic) and two fruits (Orange and Grapefruit) collected from different cities of Punjab, Pakistan.A wide variation in concentration of elements was found confirming species specific response to different elements. Chemical forms...

Organic and Inorganic pollutants from a number of sources are introduced into the water reservoirs limiting the usability and placing burden on natural resources. This manuscript is an attempt based on the applied bench scale research proposing novel adsorbents for the removal of aqueous pollutants. Nitrates and Phenols are persistent in the media and are difficult to be removed. Adsorption offers a viable and technological doable option for decontamination of industrial pollutants. Nanomaterials based on silica and alumina are synthesized using different procedures and to determine the...

Polycyclic aromatic hydrocarbons are ubiquoitous in environment. They can be produce from natural as well as from anthropogenic sources. In the present study their adsorption was studied on different soil types.Native soil have good adoptations towards degradation of organiccompounds. Degradation pattern can be expedite by controlling certain conditions. Present study concludes that in acidic pH and high organic mtter soil can degrade selected organic compounds in 12 to 24 hours.
