“…Combustion of fossil fuels in industries, homes, and transportation is an anthropogenic source of heavy metals. Vehicle traffic is among the major anthropogenic sources of heavy metals such as Cr, Zn, Cd, and Pb [32]. Higher concentrations of environmentally important heavy metals have been reported in soils and plants along roads in urban and metropolitan areas.…”

Heavy metals are well-known environmental pollutants due to their toxicity, persistence in the environment, and bioaccumulative nature. Their natural sources include weathering of metal-bearing rocks and volcanic eruptions, while anthropogenic sources include mining and various industrial and agricultural activities. Mining and industrial processing for extraction of mineral resources and their subsequent applications for industrial, agricultural, and economic development has led to an increase in the mobilization of these elements in the environment and disturbance of their biogeochemical cycles. Contamination of aquatic and terrestrial ecosystems with toxic heavy metals is an environmental problem of public health concern. Being persistent pollutants, heavy metals accumulate in the environment and consequently contaminate the food chains. Accumulation of potentially toxic heavy metals in biota causes a potential health threat to their consumers including humans. This article comprehensively reviews the different aspects of heavy metals as hazardous materials with special focus on their environmental persistence, toxicity for living organisms, and bioaccumulative potential. The bioaccumulation of these elements and its implications for human health are discussed with a special coverage on fish, rice, and tobacco. The article will serve as a valuable educational resource for both undergraduate and graduate students and for researchers in environmental sciences. Environmentally relevant most hazardous heavy metals and metalloids include Cr, Ni, Cu, Zn, Cd, Pb, Hg, and As. The trophic transfer of these elements in aquatic and terrestrial food chains/webs has important implications for wildlife and human health. It is very important to assess and monitor the concentrations of potentially toxic heavy metals and metalloids in different environmental segments and in the resident biota. A comprehensive study of the environmental chemistry and ecotoxicology of hazardous heavy metals and metalloids shows that steps should be taken to minimize the impact of these elements on human health and the environment.

“…It should be pointed out that vehicle traffic emissions are often considered as the major anthropogenic sources of potentially toxic metal(s) such as Pb, Cr, and Cd in the atmosphere. [36][37][38] PM 10 concentration shows variations during the sampling period, where its levels in six days out of the 180-day sampling period, that is, for 21% of all samples, exceeded those from available NAAQS. Such variations were also observed for Pb, Cd, and Cr concentration during the period; the concentrations of Pb and Cd during the period were lower than the World Health Organization (WHO) guidelines; however, the concentration of Cr for about 53% of the samples (15 out of 28) was higher than the WHO annual average guideline value of 2.5 ng m −3 (corresponding to an excess lifetime risk of 1:10 000).…”

This study aims to determine the health risks from some potentially toxic metal content of PM 10 on the residents of Hamadan, Iran. The mean concentration of PM 10 is 122.55 µg m -3 , and for Pb, Cd, and Cr it is 7.44, 1.78, and 2.72 ng m -3 , respectively. PM 10 levels of 22% of the samples are higher than the National Ambient Air Quality Standards (NAAQS). Pb and Cd levels are within the standard/guideline limits, whereas Cr levels exceed the guideline value in 53% of the samples. Health risks from toxic elements of PM 10 are estimated using hazard quotient (HQ) and hazard index (HI), and the cancer risk is evaluated based on lifetime daily cancer risk (CR). Both HQ and HI are <1; furthermore, children are at an increased health risk according to obtained HQ and HI values. Cr and Cd present potentially carcinogenic health risks, while CR from Pb is within the acceptable limits. Although both HQ and HI are obtained <1, conducting such health risk assessment studies really is needed to determine the air quality in different cities such as Hamadan and the obtained data can be used as general guidance for decision makers to manage the air quality.

“…Studies have shown that, such pollutants can be harmful to the road side vegetation, wildlife and the neighbouring human settlements (Turer and Mynard, 2003;Caselles, 1998;Ferretti et al, 1995;Iqbal et al, 1994;Ndiokwere, 1984;Khan and Frankland 1983). It is evident that the urban soil containing the trace metals poses a serious threat to the safety of the human life by ingestion and inhaling (Wei and Yang, 2010) and through the direct contact with the soil on the road sides contaminated by trace metal (Yang et al, 2011;.…”

The wide use of petroleum products causes contamination of air, water, soil and plants. The present study was conducted to monitor the trace metal deposition in road side soil around the petrol filling stations along the busy roads of Karachi, Pakistan. Total 21 road side soil samples were collected from selected locations of busy roads. The soil samples were digested using acid digestion method and atomic absorption spectrophotometer (AAS) was used for the elemental analysis. Results of the study showed that concentration of lead was highest in the soil samples ranging from 41.3 to 361 mg/kg, then copper from 23.0 to 101 mg/kg, manganese from 36.2 to 125.0 mg/kg and zinc from 27.5 to 213.0 mg/kg, respectively. The correlation-coefficient (r) was also calculated between the metals in soil samples. The correlation matrix showed that all the pollution is coming from the same source. The gravitational sedimentation and impact on vegetation of coarse fraction is responsible for the high lead contamination of vegetation and soils. Collected data showed that, almost all the pollution being generated by automobile exhaust in urban areas of Karachi. The soil acts as an important sink for pollutants released through different activities.
