Does radial oxygen loss and iron plaque formation on roots alter Cd and Pb uptake and distribution in rice plant tissues?

• Hao Cheng, Maoyi Wang, Ming-hung Wong, Zhihong Ye
• Plant and Soil
• 2013

Metal (e.g. Cd and Pb) pollution in agricultural soils and crops have aroused considerable attention in recent years. This study aimed to evaluate the effects of ROL and Fe plaque on Cd and Pb… (More)

• Environmental science & technology
• 2018

Changes in soil rhizosphere properties after growing the Cd hyperaccumulator Noccaea caerulescens and the Ni hyperaccumulator Thlaspi goesingense were investigated. Dissolved organic carbon content… (More)

Mechanistic insights from DGT and soil solution measurements on the uptake of Ni and Cd by radish.

• Jun Luo, Hao Cheng, Jinghua Ren, William Davison, Hao H. Zhang
• Environmental science & technology
• 2014

This work tests the previously proposed hypothesis that plant uptake of metals is determined dominantly by diffusional controlled or plant limiting uptake mechanisms at, respectively, low and high… (More)

Diffusive gradients in thin-films (DGT) for in situ sampling of selected endocrine disrupting chemicals (EDCs) in waters.

• Wei Chen, Suhong Pan, Hao Cheng, Andrew J Sweetman, Hao H. Zhang, Kevin C Jones
• Water research
• 2018

A passive water sampler based on the diffusive gradients in thin-films (DGT) technique was developed and tested for 3 groups of endocrine disrupting chemicals (EDCs, including oestrogens,… (More)
