“…Moreover, pollution with crude oil has a negative impact not only on soil characteristics, but could also increase the heavy metal content of vegetation growing on the impacted land, as shown by Bada and Olarinre in 2012 [62]. The obtained results are also confirmed by other authors that have demonstrated that crude oil contamination can lead to gradual heavy metal build-up in the soil with negative consequences on crops from such soils [63]. The present study underlines the necessity of carrying out remediation works of the contaminated site simultaneously with the health risk assessment studies based on the risk-based approach.…”

Soils contaminated with toxic and persistent pollutants pose different and serious hazards to the environment and human health. Multidisciplinary procedures that are considering models for the prediction of risk for long-term exposure are needed. The present paper illustrates the operating mode and utility of an environmental software able toe0) integrates the dose-response modeling as a major part of hazard characterization in order to assess the quantitative risk from carcinogens. In this way, risk assessment is used as a method for the investigation of contaminated sites. The method is demonstrated on a Romanian field site, contaminated with petroleum products. For the assessment of human health risks from oil-contaminated sites, the contaminants of concern are considered as polycyclic aromatic hydrocarbons (PAHs), monocyclic aromatic hydrocarbons (MAHs), and heavy metals, chemicals known as human carcinogens. Quantitative risk calculations revealed an individual risk of 1.07 × 10 −5 for children and 6.89 × 10 −6 for adults. The paper represents a utility example of an environmental software solution that could be considered by decision-making factors in approving certain projects. The software tool is helpful for protecting the environment and human health.

“…Maize is grown in most agro ecological areas especially in the Niger Delta region where oil industrial activities are predominant (Agbogidi et al, 2005a;Agbogidi et al, 2006a;Agbogidi et al, 2007). Oil pollution effects on the growth and yield of crop plant species have been variously reported by several workers to include poor growth, yield reduction and sometime death (Anoliefo, 1991;Anoliefo and Vwioko, 1994;Agbogidi et al, 2005b;Agbogidi et al, 2006a;Agbogidi et al, 2006b;Agbogidi et al, 2007).…”

“…A crop yield is a function of a number of factors and processes such as light intercepted by the canopy, metabolic efficiency of the plant, translocation efficiency of photosynthesis from the source (leaves) to economic parts and sink capacity or sink strength (Agbogidi et al, 2006b). The photosynthetic capacity of the plant determines overall productivity and the extent of development of each yield character and is dependent on the interrelationship between the various yield components The study was conducted to evaluate the effect of various levels of crude oil applied at different stages of growth on maize grain yield and yield components with a view to making appropriate recommendation to maize growers in the oil producing areas of the Niger Delta including Delta State.…”

Field experiments on the effect of crude oil levels: 0.0 (control), 5.2, 10.4, 20.8 and 41.6 ml applied at different stages of growth on maize yield and yield attributes, with a view to making appropriate recommendation to maize growers in the oil producing areas of the Niger Delta, were conducted in Ozoro, Delta State during the 2003 and 2004 cropping seasons. Seven maize varieties: Composite (suwan 1), Hybrid 3x-yx, AMATZER w, TZBRSYN w, AMATZBR y, TZBRSYN y and Ozoro local were evaluated. The experiment was laid out in a randomized complete block design with five treatments replicated four times. Crude oil application (ring application) was carried out at three weeks after planting (3 WAP), 5 WAP and 7 WAP. Plants were harvested at 112 days after planting and assessed for grain yield, 1000-grain weight, cob girth and shelling percentage. The results showed that crude oil treatment significantly reduced (P>0.05) grain yield, grain weight and cob girth but increased shelling percentage at P<0.05. Significant differences at the 5% probably level in the responses of maize varieties to crude oils were also recorded at 5 WAP and 7 WAP with Hybrid 3x-yx recording highest grain yield and weight whereas Ozoro local produced the highest cob girth and shelling percentage. Based on the results obtained from this investigation, Hybrid 3x-yx appeared to be susceptible to soils affected with crude oil, as death was eminent at higher oil doses. The open pollinated varieties (AMATZER w, TZBRSYN w, AMATZBR y, TZBRSYN y) are better in terms of relative tolerance hence should be recommended to farmers and maize growers in the oil producing areas of Nigeria. There is therefore the need to test the open pollinated varieties on farmers' field to determine their adaptability to oil pollution. Furthermore, the need for further studies to determine the level of pollution at which maize growth and yield are adversely affected cannot be overemphasized. The study established varietal differences with respect to maize response to crude oil level and this provides a basis for future breeding work by plant breeders.

“…Maize ranks third in the world production of cereal following wheat and rice [25]. It is used as feed for livestock and a principal raw material for many industrial products [24,25]. Maize classified as Zea Mays, is the common name for the cereal grass in the Poaceae, which are known to be good accumulators of contaminants [26].…”

Agricultural produce resulting from the cultivation of polluted soil can result in undue exposure and health hazards for its consumers at different level along the food chain. Available literature has shown that maize absorbs and accumulates toxic heavy metals from polluted soils. This study was designed to determine the concentration of lead (Pb), cadmium (Cd) and iron (Fe) within the leaf, stem, grains and root of maize grown on Ori-Ile battery waste dumpsite, Olodo, Ibadan Nigeria. Soil samples were collected every two months (March 2008 to July 2009) from the waste dumpsite and along the direction of the garden at 5m interval from the edge of the waste dump site. To determine the levels of uptake and accumulation of Pb, Cd, and Fe, maize was planted in a nearby house garden, situated within 25m distance away from the waste dumpsite and the root, stem, leaf and grains were harvested at maturity. All soil samples collected and the harvested maize parts were analysed for Pb, Cd, and Fe. Concentrations of Pb, Cd and Fe in soil were found to range from 3265.8±517.8 to 4351.3±1068.2; 163.96±23.2 to 258.38±123.1; 7712.90±473.8 to 8130.00±808.4 mg/kg respectively. These were significantly higher than values obtained from the reference soil (157.0±39.8, 2.2±1.2, 976.3±353.9 mg/kg respectively) and National Environmental Standard Regulation Agency (NESREA) limits (164mgPb/kg and 50mgCd/kg). Also, soil contamination factor values obtained were greater than 6 and this indicated severe contamination. Concentrations of Pb, Cd and Fe in maize-parts were significantly higher (P ≤ 0.05) than those cultivated on the reference site soil. Roots had the highest concentration of Pb (40.95±1.98 mg/L) and Cd (2.84±0.19 mg/L). In all maize-parts, bio-accumulation factor of the heavy metals was less than 1. Overall, these results have shown that the levels of metals in soil were several folds above the limits set by NESREA. Also, the range within the analysed plant parts was above the normal limit recommended for plants. High accumulation of heavy metals found in the soils of Ori-Ile battery waste dumpsite, Olodo, Ibadan bio-accumulated in maizeroots. Therefore, maize root is actively involved in phyto extraction of heavy metals from contaminated soils.
