Review on Occurrence, Sources of Contamination, and Mitigation Strategies of Phthalates in Vegetable Oils

Su Yin Wang, Man Qiu Wang, En Qi Yang, Xian Mao Chen, more

European Journal of Lipid Science and Technology > 124 > 5 > n/a - n/a

Phthalates (PAEs) are fat‐soluble pollutants with a molecular structure similar to hormones. Long‐term intake of PAEs exceeding the safe dose can lead to poisoning of the liver, kidney, lung, heart, and multiple tissue systems causing harm to the human body. Edible vegetable oil is one of the sources of human exposure to PAEs. Therefore, information on PAE levels in edible vegetable oils is very important...

Qi Wang, Jianfeng Liu, Zhao Chen, Fangbai Li, more

Science of The Total Environment > 2018 > 642 > C > 1396-1405

A comprehensive and fact-based risk assessment of heavy metals in soils is paramount for defining strategies for environmental management. However, the risk assessment approaches of heavy metals in soils are often incomplete, in particular, causation-based pollution source apportionment is absent at present. Here, we developed a causation-based method framework of an integrated risk assessment of...

Food Chemistry > 2018 > 244 > C > 254-259

9,10-Anthraquinone (AQ) was a new contaminant, with unknown sources, occurred globally in tea. European Union (EU) fixed the maximum residue limit (MRL) of 0.02mg/kg. The pollution source of AQ in tea was traced from the view of AQ deposit on tea crop by simulation. The possible contamination pathway and main factors to decrease AQ were explored in tea cultivation- tea manufacture- tea infusion, on...
