Abstract: Carrots have an important role for a life of the men. Everybody can use carrots in the meals or he drinks, he uses carrots such as the medicaments to cure many diseases, too. Carrots are very necessaries, we can tell the following effects: carrots help improve eyesight, especially, carrots contain vitamin A, essential nutrients for health of the eyes. When our bodies have the vitamin A deficiency in the long time, visual cells in the eye retina can been hurt, make dry eyes, the visual disturbances and it is serious that everyone does not see. Carrots support to cure the diabetes; help the strengthen immunity; improve the health cardiovascular; help beautiful healthy skin; can reduce the risk of cancer. Besides; everyone drinks carrot juice to stimulate hair growth and stabilize blood pressure. Carrots contain a lot of beta carotene, fiber, vitamin K1, potassium as well as antioxidants and was grown popular in all regions of Vietnam. The cultivating soil, irrigating water and carrot samples were collected in Loc Thanh village, Bao Lam district, Lam Dong province and analyzed some indicators. The results showed that the soil sample was poor in nutrient by N, P, K indicators were lower than the standards; but pH, Al3+ and Fe+ were higher than the standards. The water sample did not contain the toxic heavy metals such as: As, Pb, Cd; but the indicators of Cu, Zn, Fe were higher than the standards. For the carrot sample, the indicators of As, Pb, Cu, Zn exceeded the allowable threshold; the contents of lipid and protein were lower than the standards but NO3- was within allowable standards. However, analysis of carrot samples grown by us using organic methods showed that some heavy metal indicators such as: As, Pb, Cu were lower than allowable standards. This showed that it is necessary to choose the type of soil, water and organic method for growing carrots in order to harvest good quality carrots and safety for users. We studied an environment of soil, water and analyzed the carrots to find a nutrition level, nutritional value and the metal accumulation in order to improve a life of men.

Abstract: Spill sites, the proximity of workshops and flow stations to various ecosystems, coupled with the improper handling and disposal of waste oil, and has led to the inadvertent release of petroleum hydrocarbons into the surrounding soil. This contamination poses a significant environmental challenge as it has the potential to disrupt soil fertility dynamics, including nutrient availability, microbial activity, and overall ecosystem health. The aim of this work is to ascertain the effect of petroleum level (waste oil) on soil fertility using YORLA OIL LOCATIONS in Kpean, Khana Local Government Area of Rivers State as a case study. Two sites, Yorla Location-1, YL-LC 1 and Yorla Location-2, YL-LC 2 were assessed by collecting soil samples from different points at depths of 0.10m and 0.25m respectively and analyzed for Ammonium, Nitrate, Sulphate, and Soil Carbonate. However, experimental results shows varying values of each parameter as compared to the control sample taken 100m away from spill site. Highest TPH values for site YL-LC 1 (6232 mg/kg) and YL-LC 2 (6648 mg/kg) clearly overshoots the EGASPIN standards. Nitrate and Ammonium levels were significantly lower at all contaminated points compared to the control, indicating a consistent disruption of nitrogen cycling. Consequently, YL-LC 1 displayed elevated iron levels, indicative of potential anaerobic conditions caused by pollution, while YL-LC 2 exhibited varying manganese levels and site-specific fluctuations in potassium and calcium. This implies that the soil health has been tampered with as a result of the oil spill and remediation must be done to restore the soil to its origin state.
