Modelling drivers and distribution of lead and zinc concentrations in soils of an urban catchment (Sydney estuary, Australia)

“…5b), therefore presenting minimal risk. The study by Atapour (2015) also found zinc to be elevated, and similar to the current study, the concentrations did not exceed Australia's guideline of 7400 mg kg −1 .…”

“…Previous studies have also linked land use to elevated metal concentrations in the soil (Atapour, 2015;Facchinelli et al, 2001;Guagliardi et al, 2015;Lin et al, 2002;Snowdon and Birch, 2004). The unexpected finding may have been a result of differing contaminant sources, interactions between other covariates in the model, or due to unavailable zoning data within the land use dataset (land use class 'unknown' represented 20.4% of catchment).…”

Spatial Distribution of Heavy Metals and the Environmental Quality of Soil in the Northern Plateau of Spain by Geostatistical Methods

“…The natural concentrations of trace elements in soil play a key role in controlling the impact caused by humans and in the level of soil quality of an area [ 5 , 6 , 7 ]. Studies of soil contaminated by heavy metals have identified areas with a high risk of pollution through the analysis of atypical local spatial values [ 8 , 9 ].…”

Correlation between heavy metal concentration and oxidative potential of street dust

“…Cr had the maximum content of 35 mg/kg equal to its value in the background soil. It was reported the mean concentration of Cr equal to 36.9 mg/kg in topsoil around Kerman in the study by Atapour (Atapour 2015 ). The maximum concentration of Cu (148 mg/kg) in the western part of Kerman could be associated to the copper industry situated in this section.…”

“…As value in the street dust samples in Tehran, the capital of Iran, was reported about 6 mg/kg (Taghavi et al 2019 ). The sources of As could be associated to the natural sources, particularly from deserts and agricultural or industrial activities (Atapour 2015 ). The mean concentration of Cd was similar to its value in the background sampling point (0.34 mg/kg).…”
