Analysis of concentration trends and origins of heavy metal loads in stormwater runoff in selected cities: A review

Abstract

Abstract. The currently heavy metal pollution in rainwater is a huge problem, especially in industrial areas. Sediment from devices for stormwater runoff treatment, especially those located in city centers, industrial districts and within the area of highways is characterized by a high content of heavy metals and is found to be most contaminated. A significant fraction of these harmful chemicals are deposited on the surface of highways and urban roads and eventually transported into local waterbodies by stormwater runoff that is the primary source of water quality impairments in urban areas. This review analyzes and interprets the collected results of tests for the content of heavy metals in sediments from the urban drainage to determine the actual threat they pose to the environment. As a result of the combustion of liquid fuels, significant amounts of nickel, vanadium, cadmium and zinc get into the aquatic environment. Due to the amount of sediments accumulated in the rainwater drainage system, periodic pollution monitoring should be carried out leading to the determination of the method of management and utilization of sludge. The use of separators contributes to the reduction of the presence of heavy metals in the aquatic environment.

Contribution of low impact development practices-bioretention systems towards urban flood resilience: case study of Novi Sad, Serbia

“…The mean value of 0.58 mg/L for zinc concentrations exceeded the limit of quantification (LOQ). Zinc in stormwater can cause the quality of receiving water bodies, harm fish and other aquatic organisms [11,22].…”

“…The average lead concentration in domestic wastewater from various sources is 0.1 mg/l [3]. For storm-water wastewater, such as urban rainwater runoff, the annual concentration of heavy metals reported in the Poland/Cze ¸stochowa areas was within the range of 21.00-63.00 mg/kg [4].…”

Risk assessment of potentially toxic elements in stagnant rainwater in Northwestern México

“…In storm water the PTEs source is attributed principally to metal surfaces, vehicles, and runoff from commercial and industrial activities (McDonald et al, 2022). The PTE concentration and variety in these kinds of matrixes is a re ect of air, water, and soil pollution levels because of the anthropogenic activities that sewage water, waste, industrial emissions, and combustion residues produce (Milik and Pasela, 2018). Common PTEs found in runoff include copper (Cu), zinc (Zn) and lead (Pb) among others and can be present in different forms (available or suspended); this partition is controlled basically by factors, such as water pH, concentration and organic matter presence (McDonald et al, 2022).…”
