“…This occurrence has acute and chronic effect on plant metabolisms and responses, such as experiencing oxidative stress; lipid peroxidation, presence of malondialdehyde and disrupting the electron transport chain [5]. Elevated heavy metal concentration in the soil can lead to enhanced crop uptake and excessive metals intake in human nutrition, which can lead to acute gastrointestinal problems, respiratory damage, as well as acute heart, brain and kidney malfunction [29,30]. Many industrial activities of man have been attributed to heavy metal contamination of soil and plants in the environment, starting from the process, to the usage and waste disposal methods.…”

The general increase of heavy metal content in the soil has been largely caused by crude oil spillage. This study investigates the possibility of tomato (Lycopersicon esculentum Miller) to sorb heavy metals present in crude oil. Crude oil of 0 mL (control), 75 and 150 mL were mixed thoroughly with 15 kg of loamy soil (dry weight) in perforated plastic buckets, as the experimental pots and left for 4 days before transplanting tomato seedlings. After 12 weeks of transplanting, heavy metals analysis was carried out on plant’s fruits, leaves, stems and roots. Physicochemical analyses show that control soil had the lowest organic carbon (3.07 %) while 150 mL had the highest mean organic carbon content (8.24 %). The silt, clay and sand constituents were not significantly different (p > 0.05) in both treated and untreated soil. The control had the least pH value (6.1) while the lead (Pb) content in soil was highest in 150 mL (0.33 mg/kg) but was not significantly different (p > 0.05) from control (0.26 ) and 75 mL (0.30 mg/kg). Lead (Pb) and Cadmium (Cd) were not detected in leaves and fruits. However, bioaccumulation factor (BAF) of Cd and Ni in stem were greater than 1. Although, the concentrations of these heavy metals falls below toxic levels, its consumption could lead to adverse health effects in both man and animals through bioaccumulation or biomagnification. HIGHLIGHTS Countries with poor hydrocarbon pollution regulation are more challenging with oil spills, either through accidental discharges or indiscriminate disposal of hydrocarbon waste Plants essentially need some metals such as iron, copper among others, for their growth and other metabolic activities. However, at excess of specific limits, these metals adversely affect plant growth In this study, bioaccumulation factors (BAF) of Cd and Ni in the stem were greater than 1, this shows that the tomato plant is a hyperaccumulator of Cd and Ni from the soil GRAPHICAL ABSTRACT

This article discusses the results of chemical analysis of mobile forms of chemical elements (Cu, Ni, Pb, Zn, Co, Cd, Mb, Cr, Fe) in the soils of Aktobe city. Soil samples from 7 test plots in the territory of Aktobe city are studied. The concentrations of chemical elements are determined, and the concentration coefficients and the total index of soil pollution with heavy metals (Zc ) are calculated. The calculation results show that the level of soil pollution with heavy metals in 4–8 micro-districts and the area “Aviagorodok” is within Zc = 19.4–22.2 (16 < Zc < 33 is an average, moderately dangerous level), while in other studied zones it shows Zc < 16, i.e. low pollution.

“…Mined metal and metalloid elements, which are non-biodegradable (Tytła & Kostecki, 2019;Yan et al, 2020) may enter waterbodies and become a source of water pollution. Heavy metals can accumulate and persist in the environment (Abah et al, 2020). Among the heavy metals commonly found in wastewater and soils are cadmium (Cd), and lead (Pb), which can negatively affect the environment and human health (Kinuthia et al, 2020).…”

Vegetable cultivation using river water, which may be polluted with heavy metals, can cause health problems to consumers. A study to establish cadmium and lead levels in water from Msasa, Manyame; Mukuvisi and Nyatsime Rivers was conducted in 2019. A questionnaire survey involving 105 randomly selected urban vegetable growers was conducted to examine farmer knowledge of the potential of polluted water to contaminate produce through heavy metals. Water, soil and vegetable samples were also collected and analysed for heavy metal presence using atomic absorption spectrophotometry. Results showed that some farmers (62%) were aware that wastewater could contain heavy metals. The majority of farmers (67%) applied phosphate-based fertilisers, a potential source of cadmium. Tested at P < 0.05, the results showed that sampled water from the four sites failed to meet the Standards Association of Zimbabwe 5560 (1997) standards. Cadmium tissue concentration from wastewater from Msasa and Manyame rivers was 1.3 and 1.17 mg g −1 respectively, which were 59 and 65 times higher than 0.02 mg g −1 from the control. Water from Manyame and Nyatsime rivers contains levels of heavy
