Lead distribution in near-surface soils of two Florida cities: Gainesville and Miami

Lead, Cadmium and Iron Concentrations in <i>Zea Mays</i> Grown Within the Vicinity of Ori-Ile Battery Waste Dumpsite, Olodo, Ibadan, Nigeria

“…According to Chirenje et al [38] and Oni [2], Pb occurs naturally in all soils in concentrations ranging from 1 to 200 mg/kg with a mean of 15 mg/kg but the values obtained in this study for Rd topsoil and those of distances 0 m to 25 m along E direction from the edge of the waste dumpsite were several times beyond this range. WHO [39] reported that normal concentrations of Pb in soil to range from 15 to 30 mg/kg but this study Pb values were much higher than this value.…”

Heavy metals assessment of private drinking water supplies in Ibadan, Nigeria and associated health risks

“…Human diseases have resulted from consumption of cadmium contaminated foods (Kobayashi, 1978;Nogawa et al, 1987). The threat that heavy metals pose to human and animal health is aggravated by their low environmental mobility, even under high precipitations, and their long term persistence in the environment (Mench et al, 1994;Chirenje et al, 2004). USEPA (2004) noted that manganese is an essential element for many living organisms including human beings.…”

Metal Contamination of Soils and Prospects of Phytoremediation in and Around River Yamuna: A Case Study from North-Central India

“…It is Environmental Risk Assessment of Soil Contaminationimportant to note that floral diversity decreased with increasing contamination profile of the sites. Maximum species (20) were observed in zone 3, followed by zones 1 and 2. C. procera has been demonstrated as a potential phytoremediator species.…”

“…In general, freshwater ecosystems have low natural background metal levels and therefore tend to be sensitive to even small additions of most trace metals. Heavy metal contamination of soils and water from industrial and traffic sources in urban environments has been studied in North America and Europe [18][19][20][21][22]. Agencies like the World Health Organization (WHO) and the United states Environment Protection Agency (USEPA) have set stringent standards for maximum permissible limits of heavy metals, but there is a paucity of detailed studies on heavy metal pollution and its remediation within industrial zones in developing countries.…”
