“…It is important to highlight that Kazakhstan is one of the most important producers of these combustibles. The industrialized areas need to develop a complex system of transport and infrastructures such as roads, railways, and ports, which, according to several authors, are one of the most importann sources of pollution related to Pb, Ni, Cu, Cd and Co [40,41]. In addition, the increase in tourism should be considered in this area, because this area highly overlaps the Silk Road [42].…”

Due to an increase in poorly planned anthropogenic activities, the water quality of several Asian big rivers is highly being affected. Although the assessment of heavy metal contents is vital to develop and design sustainable water management plans, several areas in Central Asia such as Kazakhstan do not have recent studies available that evaluate this situation. One representative example of this lack of information is the Syr Darya River. Thus, this study carried out the first approach to a water quality assessment in Kazakhstan’s Syr Darya River, where a massive expansion of irrigation canals, pastures in middle- and lower-reaches and an increase in industrialization and population have lowered its potential water capacity. To achieve this goal, various physicochemical parameters were analyzed for forty-three water samples along the river under dry weather conditions at 25 cm water depth. The obtained results were analyzed using standard methods (e.g., Multi N/C 2100 S analyzer or an atomic absorption spectrometer) and evaluated by multivariate techniques (cluster analysis (CA), principal component analysis (PCA), and non-metric multidimensional scaling (NDMS)) and a heavy metal pollution index (HPI). In the CA, five cluster groups were obtained. It is important to remark that the first cluster consists of the highest number of water sampling points (8). The last cluster is made up of only one point, which shows the highest difference against the other sites in our model. The NDMS also confirmed that some specific points along the river are different. Five components were extracted from the PCA: (1) COD (chemical oxygen demand), Zn, Cu, Pb, Ni and Mn; (2) Cu, Cd, Ni and Co; (3) T (water temperature), pH and DO (dissolved oxygen); (4) T and Fe; and (5) COD and OC (organic carbon). The HPI showed very high values (279.9), which were locally confirmed in some hotspots close to the Aral Sea, industrialized areas and agricultural fields. Therefore, our results demonstrate that, under dry weather conditions, surface water resources could be mismanaged in the Syr Darya River in Kazakhstan in specific areas. For the future, considering the important role that agriculture and pasture play in the Kazakh economy, we insist upon the importance of applying water quality control measures applying nature-based solutions and efficient management plans. Moreover, we confirmed the necessity to conduct further research related to sampling under other weather situations such as wet and cold conditions, different river water depths and other locations considering specific land uses, for example, grazing, mining, railways or industries.

“…Dentro de los estudios detectados se reportó también que el uso de valores de fondo promedios a nivel mundial fue posiblemente la mejor alternativa en caso de no contar con esta información en el área evaluada [7]. En este estudio se tomaron como guía los valores reportados por Alekseenko y Alekseenko [30], del análisis de más de 300 ciudades en todas las regiones continentales; y tal como lo sugirieron Ermolin et al [7], estos valores de fondo fueron los referentes más significativos hasta la fecha a nivel mundial. En promedio, los resultados mostraron que las concentraciones de Pb, Cu, Zn, Cr, Ni y Cd en el SV fueron 2,62, 3,62, 3,04, 1,73, 1,72 y 2,45 veces superiores con respecto a las concentraciones de fondo reportadas por los estudios detectados, respectivamente (Tabla 3).…”

“…El SV también actúa como un sumidero de sustancias peligrosas y es fuente de contaminación debido a que este se re-suspende y moviliza, alcanzando entornos aledaños y cuerpos hídricos a través de procesos tales como la turbulencia inducida por el viento y el lavado generado por la escorrentía superficial [4], [5]. De esta manera, el SV se convierte en un posible indicador de contaminación ambiental por MP en ambientes urbanos [6], [7].…”

El objetivo principal de este artículo es analizar las tendencias a nivel mundial en el uso de métodos para evaluar la contaminación por metales pesados (MP) asociados con el sedimento vial (SV) urbano. Se realizó una revisión sistemática de literatura entre los años 1995-2018. Se empleó un índice de frecuencia de citación con el fin de establecer un orden de importancia para las categorías detectadas. Los resultados muestran el siguiente ordende importancia para las categorías detectadas: enriquecimiento metálico (87,0%) > riesgo sobre la salud (55,8%) > riesgo ambiental (35,1%). Los métodos de preferencia mundial para cada una de las categorías son el índice de geo-acumulación (55,8%), cociente de riesgo no cancerígeno (50,6%) e índice de riesgo ecológico (31,2%), respectivamente. Estas preferencias están posiblemente condicionadas por la existencia local de información de concentraciones de fondo de MP, dosis diarias de inhalación de partículas vinculadas a SV, factores de toxicidad por ingesta/contacto dérmico con MP, y factores de emisión de partículas de SV. Los MP de mayor relevancia son Pb (97,4%), Cu (93,5%) y Zn (89,6%). No obstante, también se destacan Cr-Cd-As por su elevado riesgo ecológico y cancerígeno.

In this study, heavy metals in road dust from 5 different land use types in urban areas were investigated to understand the characteristics and status of metal pollution. Urban roads in mixed commercial/industrial areas (MCIA) showed the highest concentration of heavy metals compared to other areas. According to the pollution load index calculation, the MCIA area was approximately 6 times more polluted than that from the residential area (RA) and traffic area (TA), in the order of MCIA>CA (commercial area)>TA>PA (parking area)>RA. The road dust from most urban areas showed significant levels of pollution in Cu, Zn, Pb, Cd, resulting in contamination by traffic related vehicles such as abrasion of tire and brake wear. However, the MCIA road dust appeared to be extremely high pollution because of the use of metals associated with industrial activity in the area. Our results showed that 270 mg of 8 heavy metals is accumulated per unit area (m 2) in the road dust. The road dust contaminated with heavy metals can be dispersed and inhaled by residents of urban areas. It can also be introduced into the surrounding aquatic and coastal environments through drainage systems during rainfall and cause heavy metal pollution in these environments. Additional research on human and environmental impacts is necessary.
