“…Our review of the literature indicates that there are many other documented examples of water contamination resulting from direct release on rivers of deep waters extracted during petroleum exploitation (Moquet et al 2014; Barraza et al 2018). In Peruvian Amazonia, downstream of several oil spills, 64% of children <10 years old showed levels of Hg higher than recommended limits (O'Callaghan‐Gordo et al 2018).…”

Indigenous peoples (IPs) worldwide are confronted by the increasing threat of pollution. Based on a comprehensive review of the literature (n = 686 studies), we present the current state of knowledge on: 1) the exposure and vulnerability of IPs to pollution; 2) the environmental, health, and cultural impacts of pollution upon IPs; and 3) IPs' contributions to prevent, control, limit, and abate pollution from local to global scales. Indigenous peoples experience large burdens of environmental pollution linked to the expansion of commodity frontiers and industrial development, including agricultural, mining, and extractive industries, as well as urban growth, waste dumping, and infrastructure and energy development. Nevertheless, IPs are contributing to limit pollution in different ways, including through environmental monitoring and global policy advocacy, as well as through local resistance toward polluting activities. This work adds to growing evidence of the breadth and depth of environmental injustices faced by IPs worldwide, and we conclude by highlighting the need to increase IPs' engagement in environmental decision-making regarding pollution control.

“…This is only partially consistent with the results of similar studies conducted in populations living in areas contaminated by oil and gas products. An increase in the concentration of Cd in the biosubstrates of residents of territories contaminated with oil products after oil spills was reported by O’Callaghan-Gordo et al [ 12 ]. The difference in the obtained results may be due to the use of different biosubstrates for analysis.…”

“…According to Relic et al, one of the hazardous soil pollutants in areas close to the petrochemical industry is Hg [ 14 ]. O’Callaghan-Gordo et al observed high concentrations of Hg in the urine of residents living in areas where oil spills occurred [ 12 ]. Webb et al showed that indigenous Peruvians and Ecuadorian Amazonians from oil extraction sites often had urine Hg levels within the World Health Organization’s global background standard.…”

“…In a study by O’Callaghan-Gordo et al, urine was used as a biosubstrate for the analysis of trace element contents. Levels of toxic trace elements in hair do not correlate with levels found in urine [ 12 ]. Hair deposits of trace elements reflect quantitative changes in trace elements and related metabolic processes over a long period, whereas the content of trace elements in urine, saliva, lacrimal fluid, and blood reflects the short-term trace element status of the organism.…”

“…Oil production is an important source of environmental pollution with elemental Hg [ 11 , 12 ], Pb [ 13 , 14 , 15 ], As [ 16 , 17 ], Cd [ 14 ], Be [ 18 , 19 ], and Al [ 20 , 21 , 22 ]. The most studied toxic trace elements are Pb, Cd, Hg, and As.…”

This study aimed to assess the relationship between the content of toxic trace elements, such as aluminum (Al), arsenic (As), beryllium (Be), cadmium (Cd), mercury (Hg), and lead (Pb), in the hair of the adult population of western Kazakhstan and the distance of their residence from oil and gas fields. The cross-sectional study included 850 adults aged 18–60 years. Inductively coupled plasma mass spectrometry was used to measure the level of Al, As, Be, Cd, Hg, and Pb in hair. The relationship between the concentration of toxic trace elements in the hair and the distance from oil and gas fields was assessed in three groups (<16 km, 16–110 km, and >110 km), using multiple linear regression analysis. The highest concentration of Hg = 0.338 μg/g was determined in the group living near oil and gas fields (0–16 km), whereas the lowest concentration of Al = 3.127 μg/g and As = 0.028 μg/g was determined in participants living at a long distance (more than 110 km) (p < 0.001). The concentration of Al (−0.126 (CI: −0.174; −0.077)), Hg (−0.065 (CI: −0.129; −0.001)), and Pb (0.111 (CI: 0.045; 0.177)) is associated with the distance to oil and gas fields. The obtained data indicate a change in the toxic trace element content in the hair of residents in the Caspian region of western Kazakhstan, a change that is most pronounced in residents living in the zone of oil and gas pollution. The distance to the oil and gas fields affects the content of toxic elements in scalp hair. In particular, the concentration of Al and Hg is associated with a decrease in the distance to oil and gas fields, while the concentration of Pb is associated with an increase in the distance to these fields. The lowest content of Al and As was determined in the hair of study participants living in the most remote areas (more than 110 km from oil and gas fields). Our results demonstrate the need for the biomonitoring of toxic elements to determine long-term temporal trends in the impact of chemicals on public health in western Kazakhstan.
