Risk assessment of heavy metals in soil previously irrigated with industrial wastewater in Shenyang, China

Metals Uptake by Wastewater Irrigated Vegetables and their Daily Dietary Intake in Peshawar, Pakistan / Pobieranie Metali Przez Warzywa Nawadniane Ściekami I Ich Dzienne Stężenie W Diecie Ludności Peszawaru, Pakistan

“…It was reported previously that plant leaves are the major sink for Fe accumulation where it is used to build chlorophyll content [29]. Iron becomes toxic to plants when its accumulation exceeds 300 mg · kg -1 especially at the soil having pH less than 5.0 [8]. The results clearly depicted the same trend for all other metals ie, higher accumulation in wastewater irrigated vegetables and low in tube well irrigated vegetables.…”

“…Wastewater irrigation is a prevalent practice for many years in most develop and underdeveloped countries of the world, such as Germany, France, India, Pakistan [4][5][6][7][8].…”

Adsorption characteristics of 1,2,4-trichlorobenzene, 2,4,6-trichlorophenol, 2-naphthol and naphthalene on graphene and graphene oxide

“…Industrialization and urbanization result in discharge of toxic chemicals in natural surface water bodies [1], including persistent aromatic pollutants, which are widely detected in the effluents of pharmaceutical, petrochemical, dyestuff, pesticide, and other industries. Numerous studies focused on the efficient removal of these toxic pollutants from aqueous solutions such as by photocatalysis [2], adsorption [3], and electrolysis [4].…”

Extractability and phytoavailability of cadmium in Cd-rich pedogenic soils

“…The contamination risk of Cd has been widely studied recently, as it is one of the most mobile and toxic heavy metals (Kumar Sharma et al, 2007;Li et al, 2009;Wei and Yang, 2010). Recent growing interest in environmental Cd contamination may likely come from increased information about the potentially harmful effects of the element associated with the increasing contamination of resources from human activities (Tran and Popova, 2013).…”
