Assessing Children’s Dietary Pesticide Exposure: Direct Measurement of Pesticide Residues in 24-Hr Duplicate Food Samples
Lu, Chensheng Alex; Schenck, Frank J.; Pearson, Melanie A.; Wong, Jon W. (National Institute of Environmental Health Sciences, 2010)Background: The data presented here are a response to calls for more direct measurements of pesticide residues in foods consumed by children and provide an opportunity to compare direct measures of pesticide residues in ... -
Estimating Pesticide Exposure from Dietary Intake and Organic Food Choices: The Multi-Ethnic Study of Atherosclerosis (MESA)
Curl, Cynthia L.; Beresford, Shirley A.A.; Fenske, Richard A.; Fitzpatrick, Annette L.; Lu, Chensheng; Nettleton, Jennifer A.; Kaufman, Joel D. (NLM-Export, 2015)Background: Organophosphate pesticide (OP) exposure to the U.S. population is dominated by dietary intake. The magnitude of exposure from diet depends partly on personal decisions such as which foods to eat and whether to ... -
The Implications of Using a Physiologically-Based Pharmacokinetic (PBPK) Model for Pesticide Risk Assessment
Lu, Chensheng; Holbrook, Christina M.; Andres, Leo M. (National Institute of Environmental Health Sciences, 2009)Background: A physiologically based pharmacokinetic (PBPK) model would make it possible to simulate the dynamics of chemical absorption, distribution, metabolism, and elimination (ADME) from different routes of exposures ... -
Quantitative Analysis of Neonicotinoid Insecticide Residues in Foods: Implication for Dietary Exposures
Chen, Mei; Tao, Lin; McLean, John; Lu, Chensheng (American Chemical Society, 2014)This study quantitatively measured neonicotinoids in various foods that are common to human consumption. All fruit and vegetable samples (except nectarine and tomato) and 90% of honey samples were detected positive for at ... -
Reconstructing Organophosphorus Pesticide Doses Using the Reversed Dosimetry Approach in a Simple Physiologically-Based Pharmacokinetic Model
Lu, Chensheng Alex; Andres, Leo (Hindawi Publishing Corporation, 2012)We illustrated the development of a simple pharmacokinetic (SPK) model aiming to estimate the absorbed chlorpyrifos doses using urinary biomarker data, 3,5,6-trichlorpyridinol as the model input. The effectiveness of the ... -
Short-term metal particulate exposures decrease cardiac acceleration and deceleration capacities in welders: a repeated-measures panel study
Umukoro, Peter E; Cavallari, Jennifer M; Fang, Shona C; Lu, Chensheng; Lin, Xihong; Mittleman, Murray A; Christiani, David C (BMJ Publishing Group, 2016)Objective: Acceleration (AC) and deceleration (DC) capacities measure heart rate variability during speeding up and slowing down of the heart, respectively. We investigated associations between AC and DC with occupational ...
