Pollution of the environment by the toxic heavy metals is a global issue of concern and affects the natural quality of the air, water, and soil. Anthropogenic activities are largely responsible for the widespread pollution of heavy metals in the environment, which is having a harmful impact on human health. Rapid urbanization, industrialization, population explosion, and use of advanced technology in developing countries have resulted in huge rise in waste production. Waste generation and disposal along with landfills is a serious global environmental threat resulting in heavy metal contamination of the soils, water, and plants. Heavy metals reaching in the atmosphere result to the deterioration of the quality, and contamination of the soil and groundwater along with damage to the living organisms. The present review describes the analysis of heavy metal pollution of the environment with respect to air, animals, aquatic ecosystem, plants, and soil. Special emphasis is provided on sources of heavy metals in the environment, harmful impacts of heavy metals on the environment and strategies to control heavy metal pollution of the environment. Present study is based on critical review and analysis of scientific information published by academic and professional researchers who studied the impact of heavy metal pollution on the environment. Research articles on impact of heavy metal pollution on the environment published in high impact factor journals were referred for collection of databases. This study notices that there is an urgent need for continuous monitoring of various environmental elements for heavy metals in different open dumpsites. It also recommends that nanomaterials, such as metal oxide nanoparticles, graphene and its derivatives, magnetic nanoparticles, and carbon nanotubes should be used to remove the toxic heavy metals from the air, water and soil.

“…Power generation and transmission are two of the major causes of cancer in humans [12,13]. Reports have shown that power transmission and distribution activities can elevate the concentrations of metals in the environment [14][15][16][17][18]. Metals such as aluminum (Al), copper (Cu), iron (Fe), cadmium (Cd), and lead (Pb) are closely associated with power transmission and distribution, hence, the environment could be contaminated by these metals over time.…”

The generation, transmission, and distribution of power have both positive and negative effects. However, this has not been effectively assessed and documented in the study area. Hence, this research was conducted to assess the impact of power transmission and distribution activities on the levels of trace metals in soil, including Telfairia occidentalis (T. occidentalis). In this research, topsoil and T. occidentalis were obtained from the vicinity with high tension copper cables at Ikono, Ibiono Ibom, Itu, Uyo, and Uruan in Akwa Ibom State. Similar samples were obtained 100 m away from areas with high-tension copper cables and used as controls. The mean values (mg kg-1) of cadmium(Cd), copper (Cu), iron (Fe), and lead (Pb) obtained in soil were 2.13 ± 1.24, 43.52 ± 9.28, 1,265.84 ± 287.33, and 27.39± 5.66, respectively. Whereas, the mean concentrations (mg kg-1) of these metals in T. occidentalis were 0.17 ± 0.10, 12.98 ± 2.50, 217.81 ± 62.56, and 1.47 ± 1.40, respectively. The results obtained revealed that the mean concentrations of Cd, Cu, and Fe in soil were higher than their recommended safe limits, while the mean concentrations of Cu, Fe, and Pb in T. occidentalis exceeded the limits. The results indicated that the mean concentrations of all metals in the impacted soils were higher than in the control plot for both soil and T. occidentalis. Pollution models employed showed that soils and T. occidentalis from the studied locations were highly impacted by metals originating mainly from power transmission and distribution activities. The estimated daily intake rate of all the metals through soils and T. occidentalis was investigated for the children and adult groups within their recommended oral reference doses except for Cd. The non-cancerous risks for the children and adult groups for both soil and T. occidentalis were less than than 1 mg kg-1 day-1. However, the children’s class was more susceptible. Cancer risks for both the children and adult groups via soil and T. occidentalis were within the acceptable limit, but the entire cancer risk for the children via T. occidentalis from the Uyo vicinity was higher than the safe limit. This study revealed the effects of power transmission and distribution activities on the metal loads in soil and T. occidentalis and the related human health problems. Consequently, consistent exposure to soil particles impacted by high-tension cables and the cultivation of edible plants under high-tension cables should be avoided.

“…The anthropogenic pollution is known as pollution caused by conventional fuels, chemicals, noise, electromagnetic fields and waste pollution [22][23][24]. A third source of atmospheric pollution with heavy metals is the biotic environment, through vegetation, the residues' storage, and manure [25][26][27].…”

The rapid technological development of society determined increased demand for safe potable water and food resources. Unfortunately, this progress causes complex environmental pollution, that is continuously challenging the scholars’ community. Therefore, it is important to chemically analyze the food for a better understanding of pollution-spreading mechanisms. Our study is focused on food analysis originating from Vatra Dornei City, which belongs to Suceava County in the Bukovina region of Romania. It represents a well-known Romanian spa and ski resort in the northern parts of the Oriental Carpathians Mountains. The mountain region owns a lot of mineral resources, mainly consisting of mineral and sparkling waters, uranium, manganese, copper, pyrite, chalcopyrite, polymetallic ores, baryte, gold and silver-bearing orebodies, etc. The present contribution aims to point out the results obtained from the analysis of soil, water and food samples collected from the local markets. The food samples consisted of lettuce, spinach, apples, pork (smoked) chicken meat (raw), milk and cheese. Last year the survey was conducted over six months. The results highlighted that the mining activities carried out during time caused environmental pollution with uranium and heavy metals due to the waste heaps’ weathering phenomena and tailing ponds’ presence.
