“…Metals water and soil. Metals of anthropogenic origin are commonly from agricultural activities, i.e., the use of fertilizers and pesticides, in addition to the emissions from metal plating, mining operations, fertilizer industries, tanneries, paint industry, battery manufacturing, paper industries, pesticides industry, transportation, and sewage treatment plants (Bradl 2005).…”

The levels of four metals (Zn, Cu, Cd, and Pb) were evaluated in two fruit types (apricot and fig), a fruity vegetable (tomato), and three leafy vegetables (arugula, spinach, and lettuce) that are commonly grown and consumed in Aseer Region, Saudi Arabia. Flame atomic absorption spectrophotometry was employed for quantification. The quality of results was checked by a certified reference material (NIST SRM 1570a). Good recovery values in the range of 87-104% were achieved. Metals were quantified in washed and unwashed samples to evaluate the effect of washing. Statistically, no significant difference was noticed (p>0.05), except for Zn in arugula and Cu in apricot and spinach. The levels of metals found in the analyzed fruits and vegetables were in their normal ranges in crops and not posing any serious risks to the consumers in Aseer Region. The toxic elements Pb and Cd were well below the maximum levels set in the Saudi and international food standards. Zn and Cu levels were comparable to the ranges reported in worldwide previous studies.

“…It poses a threat to the environment because the used lube oil contains toxic heavy metals which resulted from oil additives, mechanical wear, and chemical corrosion (Bradl 2005;Hu et al 2013). Different kinds of anthropogenic activities such as improper disposal of refinery wastes, leaking petroleum storage tanks, former train stations and railroads, industrialized areas, landfills, and mining sites have all become the source of lube oils and heavy metals (Alloway 2013;Jones et al 2013;Nordmark et al 2011;Rutkowska et al 2015;Torres et al 2007;Osman 2014;Wiłkomirski et al 2011).…”

Thermal treatment of soil polluted by lube oil and heavy metals (cadmium, chromium, copper, and lead) was carried out by using a laboratory-scale incinerator. The effect of co-contaminated soil mixtures as fixed/fluidized bed media was studied with different ratios of sand bed amount to soil feeding. Additionally, the effect of soil moisture content on incineration system was further investigated. The reduction in air input altered the mode of fluidized bed to fixed bed which resulted in an increase in organic pollutants such as benzene, toluene, ethylbenzene, xylene, and polycyclic aromatic hydrocarbons. The combustion efficiency of fixed bed mode was observed to be relatively high at a lower ratio of sand bed amount to soil feeding, whereas high combustion efficiency was found in fluidized bed mode at a higher ratio of sand bed amount to soil feeding. Much higher concentration of organic pollutants in both gas phase and bottom ash is found under a higher soil moisture content. In addition, the increase in moisture content has resulted in an increase in lead, cadmium, and chromium in fly ash while copper was decreased. An important consideration is that the partitioning of heavy metals was randomly distributed in particle sizes of bottom ash. The highest concentration of heavy metals was deposited on fine-sized particle. The distribution of heavy metals in medium-sized and coarse-sized particles to form eutectic species might be produced by the soil-sand aggregation.

“…Sources of heavy metals in the atmosphere are mineral dusts, sea salt particles, volcanic aerosols, forest fires, and industrial sources such as coal combustion [25]. Eight trace elements (Fe, Cu, Pb, Ni, Co, Zn, Cd and Mn) of groundwater samples were analyzed in the area and then compared with the WHO [17] and IQS [18] standards, as in Table-4 which shows that the concentrations all of trace elements falls within limits permissible for drinking water purposes except Fe and Pb in the wells (5,10,16) and (1,2,7,10,12,14,21) respectively, may be owing agricultural activities and weathering of clay minerals in the Quaternary deposits which cover the area, in addition to exist industrial area, Table-8.…”

Groundwater suitability for consumption in the Yaychi area is determined by analyzing groundwater samples of 21 wells distributed in the area, for dry period which begin from May to October 2016 and wet period begin from October 2016 to May 2017. Results indicated that the temperature (T °C) have normal values and the water of low alkaline and excessively mineralized, while most of these samples, for both periods, are slightly -brackish water. The mean ion concentrations for two periods indicates that all major and secondary ions are higher than water quality standards for drinking purposes according to World Health Organization (WQI) and Iraqi Standard (IQS) except for K and Cl ions. The water in the study area is classified as very hard. Kurolov formula shows the presence of three predominant salts MgSO 4 , Na 2 SO 4 and CaSO 4 , and the water origin in the area is meteoric water. The predominated of water types are " earth alkaline water with increased portions of alkalis with prevailing sulfate and chloride" and "Normal earth alkaline water with prevailing sulphate or chloride". After comparing the ionic concentrations with the water quality standards for different purposes, it was found that groundwater in the area is unsuitable for human drinking, but it's suitable for building and livestock and for growing most types of crops, it is also suitable for irrigation purposes depending on the sodium adsorption ratio (SAR), Soluble Sodium Percentage(Na%) and the Residual Sodium Carbonate (RSC), and unfit for irrigation according to Magnesium Adsorption Ratio(MAR) index. The water in the study area is devoid of heavy metal pollution except (Fe), (Pb) which are shown in water of some wells.
