This study aimes to assess the spatial and temporal (seasonal) variation of physico-chemical characteristics (electrical conductivity, pH, organic matter and …

The elements of P, Cd, Cu, Pb, Se and Zn were further investigated. Cu, Cd, Pb and Zn are frequently studied metals (Goodyear and McNeill 1999), as elevated levels might be toxic to organisms. Zn and Cu are essential trace metals; whereas, Cd and Pb are in general considered non-essential (e.g. Rainbow 2002; Hejna et al. 2018). P is an ...

Determination of heavy metals; cadmium (Cd) and lead (Pb) as well as trace elements; copper (Cu) and zinc (Zn) contents in legumes, cereals, cereal products and fried potatoes purchased from the Egyptian market were carried out using atomic absorption spectrometry. The heavy metal amounts detected in legumes ranged from 0.010 to 0.178 mg.kg-1 of …

Sungai Puloh mangrove estuary supports a large diversity of macrobenthic organisms and provides social benefits to the local community. Recently, it became a major recipient of heavy metals originating from industries in the hinterland as a result of industrialization and urbanization. This study was conducted to evaluate mobility and …

Lead accumulates in plants by soil-plant interaction as its adsorption has been detected in roots of many plants such as Helianthus annus [7], Lactuca sativa [8], Chenopodium murale [9], Brassica juncea [10], and Nicotiana tabaccum [11].The extensive roots of plants absorb mineral nutrients along with free-Pb 2+ ions from the Pb …
