“…They mentioned that the reduction in the electrostatic interaction between soil particles and water enhanced by a thin film of low-polarity of the compounds (i.e., hydrocarbons), around the polar surfaces of the soil organic matter (SOM) and clays, could be the reason (Adams et al, 2008a and2008b). When dry, a film of petroleum hydrocarbon covers soil particles, bind them together and on the surface, it form a crust (Marı´n-Garcı et al, 2016).…”

Petroleum and petrochemical hydrocarbons for some places are serious sources of environmental pollutants. To remediate these contaminants, phytoremediation, a relatively low cost and an environmental friendly technique is recommended more widely, now more than ever. Successful and effective applying of hydrocarbons phytoremediation depends mainly on the soil and plant types and conditions and microbial activities and the interactions between these three factors. Although for the last several decades, various plant and organism's species for the phytoremediation processes have been extensively studied, evaluating and characterizing soil properties, as an important objective for sustainable remediation and land use management, which had negligible considerations. An ideal soil for phytoremediation should have proper physical, chemical and biological characteristics to let the plant grow well and produce biomass as high as possible. It also should provide favorable conditions for microbial activities to perform efficient remediation. Soil physical characteristics such as texture, structure, water status and aeration are important factors affecting the microbial activities and consequently the degree of remediation potential. A better understanding of soil physical properties in conjunction with proper soil-plant-microbe management could be exploited to enhance the remediation of hydrocarbon contaminated soils and thus sustainable healthy environment.

“…These kinds of hydrocarbons have very low toxicity, but they do alter physical-chemical properties which are important for soil fertility such as field capacity, cation exchange capacity, bulk density, porosity, pH, electrical conductivity and soil temperature (Adams et al, 2008b(Adams et al, , 2008c. Several studies have been made related to pasture production in marshy soils impacted by weathered hydrocarbons in the region.…”

ABSTRACT:A site evaluation was made for a low-lying property in an old river levee/marsh association, used marginally for cattle raising, which was contaminated due to historical practices. Contamination was related to geomorphology: the lowest areas contained 79 % of the contaminated samples. Other contaminated samples were all rear access roads (probable intentional dumping). There were no samples in the higher, levee areas away from roads with hydrocarbon concentrations above 3,000 mg/kg. Medium and high impact levels, corresponding to average hydrocarbon concentrations of 13,400 mg/kg and 109,700 mg/kg, respectively, were found in 28 % and 27 % of the property area. The medium impact level was predicted to have a reduced pasture production potential of ~ 50 % while at the high impact level practically no pasture production was predicted. Toxicological risk to cattle is present in only 12 % of the sample points although almost all of these are in very marshy areas not apt for cattle raising. Because the hydrocarbons at this tropical site are very weathered, acute toxicity was not related to hydrocarbon concentration. Although slightly more than half of the property has hydrocarbon concentrations above the permissible limit, only about one-third of the contaminated area is apt for cattle raising. This study, based on hydrocarbon distribution related to site geomorphology, soil toxicity bioassay, risk assessment to cattle and evaluation of pasture production allowed to made a more accurate assessment and definition of future use of the site. These criteria could be used for diagnostic studies of sites with similar tropical conditions.

“…Trace metals are ubiquitous in aquatic environments [7]. Some of these metal contaminants are crucial due to their potential toxicity [8] and have potential impact on human health if they reach levels such that they constitute toxic pollutants [9].In addition, metals including Cu, Fe, Mn, and Ni are essential micronutrients for the life processes of animals and plants [10], but imbalances of these metals may be fatal [11]. Furthermore, [12] observed that elements such as As, Pb, Zn, and Cd exhibit extreme toxicity, even at low levels.…”

Selected trace metals investigation of agricultural soil at sawah, vegetable and river sediment in Sumani watershed, West Sumatra, Indonesia were conducted to determine their abundances and to assess contamination levels. pH, CEC and TC values indicates moderate to high soil fertility status. Average concentrations of Pb, Zn, Cu, TiO2, Fe2O3 and P2O5 were greater than those of Bulk Composition Crust (BCC) and UCC in most areas. Enrichment factor values at Sawah confirms depletion to minimal enrichment with most metals, while vegetable area indicates moderate enrichment with Pb, Cu and Rb, and depletion to minimal enrichment for Zn, Ni, Cr, V and Sr. Igeo values for Pb, at Sawah were unpolluted to moderately polluted but practically unpolluted for Zn, Cu, Ni, Cr, V, while vegetable area were moderately polluted with Pb, unpolluted to moderately polluted with Cu and Rb and and practically unpolluted for Zn, Ni, Cr, V and Sr. Elevated values of Pb in vegetable area, possibly due to volcanic ash from mount Talang, excess application of fertilizers and pesticides, and high contents of Pb in gasoline, Indonesia.
