The contamination of phthalate esters (PAEs) has become a potential threat to the environment and human health because they could be easily released as plasticizers from the daily supply products, especially in polyethylene films. Concentration levels of total six PAEs, nominated as priority pollutants by the US Environmental Protection Agency (USEPA), were investigated in soils and vegetables from four greenhouse areas in suburbs of Nanjing, East China. Total PAEs concentration ranged from 930±840 to 2 450±710 μg kg −1 (dry weight (DW)) in soil and from 790 ± 630 to 3 010 ± 2 130 μg kg −1 in vegetables. Higher concentrations of PAEs were found in soils except in Suo Shi (SS) area and in vegetables, especially in potherb mustard and purple tsai-tai samples. Risk assessment mainly based on the exposures of soil ingestion and daily vegetable intake indicated that bis(2-ethylhexyl) phthalate (DEHP) in the samples from Gu Li (GL) and Hu Shu (HS) exhibited the highest hazard to children less than 6-year old. Therefore, the human health risk of the PAEs contamination in soils and vegetables should greatly be of a concern, especially for their environmental estrogen analog effects.

The proposed method for Miniature Inertial Measurement Unit (MIMU) system enables the exact measurement of sports parameter even under challenging conditions. With the aid of sports biomechanical parameter, proposed method suppresses the drift. The Hilbert-spectrum responds the sports rhythm law. It will provide aided information for trainer.
