“…In the municipalities of Tepetitla de Lardizabal and Nativitas, located in southern Tlaxcala, 6289 ha of land are used for growing corn, fodder oat, chard, coriander, broad bean, bean, onion, spinach, and pumpkin (COPLADET, 2009). There are almost no studies showing the presence of pollutants in the sediments from these rivers; certain works are focused on assessing the water pollution by the volatile organic compounds (Navarro et al, 2004) and metals (García-Nieto et al, 2011), as well as to evaluate the impact of these contaminants on agriculture soils (Méndez et al, 2000).…”

“…These compounds are moved long distances and then accumulate in soils, sediments, and biological tissues (González-Mille et al, 2010;Liu et al, 2011). Sediments are an essential component of the freshwater ecosystems; the studies conducted in several countries, including Mexico, indicate that sediments are contaminated by pesticides and chlorinated biphenyls (PCB) (Echols et al, 2008;González-Mille et al, 2010), polycyclic aromatic hydrocarbon (PAH) (Echols et al, 2008), dioxins, and furans (Wang and Lee, 2010), and almost invariably heavy metals (García-Nieto et al, 2011).…”

“…Al respecto, Méndez-García et al (2000) reportaron 0.21 mg/L de Pb y 0.03 mg/L de Cd en agua y 4.22 mg/kg de Pb y 0.30 mg/kg de Cd en suelos. Y García-Nieto et al (2011) obtuvieron valores de 0.95 mg/L de Pb y 0.94 mg/L de As en agua y de 127.7 mg/kg para As y 89.5 mg/kg para Pb en el caso de los suelos.…”
