Total elemental composition of soils contaminated with wastewater irrigation by combining IBA techniques

Comparative study on open system digestion and microwave assisted digestion methods for metal determination in shrimp sludge compost

“…Concern over adverse human and ecological health effects of accumulation of heavy metal contaminants in the environment is increasing [11][12][13][14]. Heavy metal pollution accumulated in agriculture soil influences the ecosystem nearby.…”

Distribution and sources of bioaccumulative air pollutants at Mezquital Valley, Mexico, as reflected by the atmospheric plant <i>Tillandsia recurvata</i> L.

“…Tillandsia recurvata has some physiological resistance to high levels of O 3 and SO 2 (Benzig et al, 1992), which may partially explain why is it so abundant at the polluted MV. This and other atmospheric Tillandsia species have been used as in situ air pollution biomonitors in some southern US states and Latin-American countries, where this genus is exclusively distributed (e.g., De Sousa et al, 2007;Husk et al, 2004;Pignata et al, 2002;Pyatt et al, 1999;Schrimpff, 1984;Smodiš et al, 2004;Wannaz et al, 2006a, b). Successful transplanting of Tillandsia from rural into urban areas for similar purposes has been reported by Brighina et al (2002), Figuereido et al (2007), and Malm et al (1998).…”

Geochemical data: acidic igneous rocks, calculated from Verma-Surendra (2001); agricultural soils, median values amongFlores- Delgadillo et al (1992),Hernández-Silva et al (1994),Huerta et al (2002),Lucho-Constantino et al (2005), andSiebe (1994); limestone(Lozano and Bernal, 2005).…”

Heavy Metal Contamination of Zn, Cu, Ni and Pb in Soil and Leaf of Robinia pseudoacacia Irrigated with Municipal Wastewater in Iran

“…1). As a matter of fact, high concentration of heavy metals in wastewater leads to increase them in soil (Huerta et al, 2002;Nan et al, 2002;Mapanda, et al, 2005). The comparison of soil Zn, Cu, Pb and Ni with critical range of heavy metals in soil (Table 3) showed that only Ni of soil treated with municipal wastewater and Pb of soil treated with the both municipal wastewater and well water were higher than the standard amounts of soil.…”
