Physico-chemical properties and heavy metals content of soils were determined from seven farms in Minna, central Nigeria. Conventional analytical methods were employed to determine the physico-chemical properties and the heavy metals were analysed by atomic absorption spectrometry. The result showed that pH values ranged from 6.64 - 7.70 indicating slight acidity to slight alkalinity of the soils. The total organic carbon values ranged from 0.95-2.25 % resulting in the presence of organic matter (1.63-3.87). The electrical conductivity values ranged from 17-37 μS/cm. The cation exchange capacity of the soil samples ranged from 3.68-5.15 cmol/kg. The heavy metals levels were in the following range: Cd (0.00018-0.00134 mg/g), Cu (0.0069-0.0476 mg/g), Fe (1.942-2.2059 mg/g), Mn (0.1825-0.3696 mg/g), Ni (0.0065-0.0069 mg/g) and Zn (0.0157-0.2252 mg/g). The concentration of the metals in the soil samples varied according to the following trend: Fe>Mn>Zn> Cu>Ni>Cd. The average concentration of all the metals in each farm also gave the trend Farm B>Farm G>Farm E>Farm C>Farm F>Farm D>Farm A. The findings indicate the presence of heavy metals in all the farms but only Fe was above the FAO/WHO standards.

The paper deals with monitoring of pollution arising due to agrochemicals and pesticides manufacturing industries located along the Dombivali industrial belt of Mumbai, India. The study was carried for the period of one year from June, 2012 to May, 2013 to study the level of toxic heavy metals and the physico-chemical properties of waste water effluents discharged from the above industries. The average concentration of Cu, Ni, Cr, Pb and Zn was found to be maximum of 29.86, 0.90, 1.16 and 1.19 ppm respectively in summer season, while average Fe concentration was maximum of 51.10 ppm in winter season. The average pH value of the effluent was found to be maximum of 12.95 in summer season, while average conductivity value was maximum of 21085 µmhos/cm in rainy season. The majority of physco-chemical parameters like alkalinity, hardness, salinity, chloride, cyanide, phosphate, total solid, BOD and COD content were found to be maximum in summer season having the average values of 1918, 186, 4, 11.20, 0.07, 81, 6391, 685 and 2556 ppm respectively. The average DO content was found to be low of 4.5 ppm in winter season. It was observed that the concentration level of majority of the toxic heavy metals and physico-chemical properties were above the tolerable limit set for inland surface water. The results of present study indicates that the existing situation if mishandled can cause irreparable ecological harm in the long term well masked by short term economic prosperity due to extensive industrial growth

Four major soil series (Jharokuali, Kumaradapalli, Ranibara and Kantiagada) representing the cashew growing soils in coastal Odisha, which are developed from different parent materials were studied for their morphological, physico-chemical properties and their suitability for cashew production. Soils are moderately deep to very deep, well drained, texture varied from sand to sandy clay. The soils are slightly acidic to moderately alkaline in nature. A cation exchange capacity is low. Plant available nutrients status of soils are low in N, low to high in available P and K. The DTPA-extractable Fe, Cu and Mn were sufficient. Available Zn is sufficient in surface horizons while deficient in subsoils.The soils at the order level are classified as Alfisols and Entisols at sub group level as Typic Rhodustalfs, Typic Haplustalfs and Typic Ustipsamments. Interpretative groupings for Land Capability, Land Irrigability and Suitability were assessed and identified soil related constraints and suggested appropriate managements measures to improve Cashew productivity.

Some of the major concerns when applying sewage sludge to land include the potential effect on pH and cation exchange capacity; the mobility and the accumulation of heavy metals in sludge treated soil; the potential of applying too much nutrients and the problems associated with odors and insects. The main objective of this study is to identify the effects of sewage sludge application on the physical and chemical properties of sludge treated soil. Sewage sludge was applied to soil at various rates ranging from 0 L/m2 to 341 L/m2. In order to simulate the natural environment, the study was carried out at a pilot treatment site (5.2 m × 6.7 m) in an open area, covered with transparent roofing material to allow natural sunlight to pass through. Simulated rain was applied by means of a sprinkler system. Data obtained from sludge treated soil showed that the pH values decreased when the application rates were increased and the application period prolonged. The effect of sewage sludge on cation exchange capacity was not so clear; the values obtained for every application rate of sewage sludge did not indicate any consistent behaviour. The mobility of heavy metals in soils treated with sludge were described by observing the changes in the concentration of the heavy metals. The study showed that Cd has the highest mobility in sludge treated soil followed by Cu, Cr, Zn, Ni and Pb.

To provide the quality required for its use, raw kaolin must be subjected to certain processing procedures like delamination which is applied to the layered structure materials. The aim of this research is to determine the possibility of performing delamination in the extruder and to estimate the effects of this process on the physico-chemical properties of kaolin. The results showed that delamination can be efficiently realized in the extruder by shearing densely packed layers under the influence of friction force and added Na2CO3 electrolyte. The crystal structure of the system was thus disrupted. This was confirmed by the Hinckley index (HI) decrease and by the dilatometric characteristics changes during heating. The particle size was reduced and, furthermore, new adsorption centers were formed, which led to an increase in the total cation exchange capacity (CEC). The plasticity of kaolin decreased with the increasing delamination degree, as well as the amount of water required for plastic processing, which is favorable in drying ceramic products.

This study compares the physico-chemical characteristics of three different types of biochar produced from biomass residues in Vietnam as a basis for optimising their application in water purification and soil fertilisation.  Wood biochar (WBC), rice husk biochar (RBC), and bamboo biochar (BBC) were produced under limited oxygen conditions using equipment available locally in Vietnam, known as a Top-Lid Updraft Drum (TLUD). The resulting biochars were characterised using a suite of state-of-the-art methods to understand their morphology, surface chemistry and cation exchange capacity.  Surface areas (measured by BET) for WBC and BBC were 479.34 m2/g and 434.53 m2/g, respectively, significantly higher than that of RBC which was only 3.29 m2/g.  The morphology as shown in SEM images corresponds with the BET surface area, showing a smooth surface for RBC, a hollow surface for BBC, and a rough surface for WBC.  All three biochars produced alkaline, with pH values around 10, and all have high carbon contents (47.95 - 82.1 %).  Cation exchange capacity (CEC) was significantly different (p<0.05) among the biochars, being 26.70 cmol/kg for RBC, 20.7 cmol/kg for BBC, and 13.53 cmol/kg for WBC, which relates to the cations (Ca, Mg, K) and functional groups with negative charge (carboxyl, hydroxyl) present on the biochar surfaces.  The highest contents of Ca, Mg and K in rice husk BC may explain its highest CEC values.  Thus, although the biochars were produced by the same method, the various feedstocks lead to quite different physico-chemical properties.  Ongoing work is linking these physico-chemical properties to the biochar efficiencies in terms of nitrate and ammonia capture capacities for use as fertilisers, and for adsorption of heavy metals (Zn, Cu) or water filtration, in order to design optimal biochar properties for specific applications.

Roadside Dust

University of Ilorin is one of the most populated Universities in Nigeria. Roadside dust was collected from the busiest roads of the university permanent site and level of heavy metals (Fe, Cu, Zn, Cd and Pb), organic carbon and physico-chemical properties of the dust were assessed. Atomic Absorption Spectrometry (Buck Scientific 210/211VGP) was used to analyse for heavy metals while appropriate standard methods were employed for the determination of organic carbon, pH, conductivity, particle density and bulk density of the roadside dust. The pH of dust from all roads was almost alkaline (7.2 – 7.6), particle density ranged from 1.60 - 2.14 gml-1, bulk density ranged from 1.03 – 1.62 gml-1, electrical conductivity ranged from 0.25 to 0.57µScm-1, organic carbon (OC) content of all roadside dust ranged from 0.9 % - 1.2 %. While Pb was obtained to be absent in all the roadside dust samples, it was observed that the abundance of other heavy metals at all the various sampling points and control followed the order Fe >>>Zn >> Cu > Cd. The average level of Fe in the control site was 2443.85 mg/kg which was very lower to that from other sites in the study. The results for the metal pollution index (MPI) show that all the roads were polluted with Fe, Cu, Zn and Cd. The levels of the metals showed a dependence on anthropogenic pollution such as vehicle density compared with the control site.

Extensive industrialization in the southern part of Gujarat is characterized by regional pollution of soil and water resources. In view of this, the present study has been undertaken in Ankaleshwar, one of the biggest industrial townships of India. About, 25 surface sediment /soil samples were collected from top 10 cm representing entire study area and were analyzed for heavy metals by using X-ray fluorescence spectrometer (XRF). The heavy metals concentrations were compared with the standard shale to find out pollution index (PI), results shows the significant enrichment for arsenic, moderate enrichment for Pb and minimal enrichment for metals in descending order as Fe>Mn>Cr>Ni>Co>Zn>Cu>Mo. Physico-chemical properties such as texture, cation exchange capacity, total carbonate and organic matter, as well as the percentages of the sand, silt, and clay fractions have been examined. It is observed that heavy metals like Ni, Cu, Zn, and Mo show a positive correlation with the silt size fraction. Similarly, Mn, Cr, As, and Pb show positive correlation with clay size fraction. Chemical properties like EC, CEC and organic matter have control over majority of heavy metals. High correlation with these properties suggests that higher ionic conductivity soils have high heavy metal content. The effect of these properties can be arranged in descending order as follows: EC >OM > Clay % >Silt % > CEC.
