Soil contamination is a public health concern in many countries but methods to assess dietary risk from soil metal toxicity have not been standardized worldwide. Laboratory data on urban soils are limited and do not adequately link metal content to associated food plant uptake. Cadmium is a health risk because it accumulates in lettuce and may be consumed at high levels by childbearing women. T...

In situ inactivation of soil Pb is an alternative to soil removal and replacement that has been demonstrated in recent years at industrial sites with hazardous soil Pb concentrations. Most children exposed to elevated soil Pb, however, reside in urban areas, and no government programs exist to remediate such soils unless an industrial source caused the contamination. Modern regulated biosolids ...

Spatial statistical methods including Cokriging interpolation, Morans I analysis, and geographically weighted regression (GWR) were used for studying the spatial characteristics of polycyclic aromatic hydrocarbon (PAH) accumulation in urban, suburban, and rural soils of Beijing. The concentrations of PAHs decreased spatially as the level of urbanization decreased. Generally, PAHs in soil showed...

introduction: reuse of wastewater for agricultural irrigation is increasing due to an increased demand for water resources in different parts of the world. almost 70% of deviated water from rivers and pumped groundwater is used for agriculture. if wastewater is used for irrigation in agriculture, then the amount of discharged water from natural sources will be decreased and the flow of wastewat...

to study the effects of soil amendments on physical and hydraulic properties of a saline-sodic sandy clay loam soil, a field experiment was carried out as a complete block design with three replications. the treatments in this research consisted of control (b), 10 ton ha-1 gypsum (g), 10 ton ha-1 urban solid compost (c), three levels of vinyl alcohol acrylic acid (s1= 0.05%, s2= 0.1%, s3= 0.2%)...

BACKGROUND AND OBJECTIVES: Urban farming makes a substantial influence on the household economy of the urban poor especially in developing countries. Urban soil the hot spot of urban farming is a natural sink for contaminants especially the trace elements derived mainly from anthropogenic activities. This study’s aim was to quantify the concentrations of selected trace elements...

Recent urban landscape vegetation surveys conducted in many cities in China identified numerous plant nutrient deficiencies, especially in newly developed cities. Soil nutrients and soil nutrient management in the cities of Hubei province have not received adequate attention to date. The aims of this study were to characterize the available nutrients of urban soils from nine cities in Hubei pro...

We used data available from the literature and measurements from Baltionore, Marylan6 to (i) assas inter-city variebifity of soil oqanic carbon (SOC) pools (1-m depth) of six cities (Atlanta, Balbore, Boston, Cbifago, Oakland, and Syracuse); (ii) calculate the net effect of urban land-use conversion on SOC pools for the same cities; (iii) use the National Land Cover Database to extrepolrrte tot...

In the municipality of Bor (Eastern Serbia), which is known for its production of copper from sulphide ores, soil was sampled in urban, rural and background area. The content of metals (Pb, Cu, Cd, Zn, Ni, Cr) and metalloids (As, Sb, Se, Te) in the soil was determined. The highest concentrations of the analyzed elements and frequent exceedance of the limit values were observed in soil samples f...

Urban gardens provide affordable fresh produce to communities with limited access to healthy food but may also increase exposure to lead (Pb) and other soil contaminants. Metals analysis of 564 soil samples from 54 New York City (NYC) community gardens found at least one sample exceeding health-based guidance values in 70% of gardens. However, most samples (78%) did not exceed guidance values, ...
