“…OPs used as additives in materials are not chemically bonded; hence, OPs may easily be released into the environment over time . As a consequence, they have been widely detected in air particles, house dust, drinking water, and baby food; this contamination leads to human exposure. − Limited animal studies have suggested that certain OPs may be neurotoxic, carcinogenic, and endocrine disruptors. − TNBP was determined as a neurotoxic agent after chronic exposure in rodent . Cl–OPs are suspected carcinogens; for example, TCEP was related to tumor growth in the kidney and thyroid, and TDCIPP might cause cancer in the brain, liver, and testes .…”

In this study, three chlorinated (Cl–mOPs) and five nonchlorinated (NCl–mOPs) organophosphate metabolites were determined in urine samples collected from participants living in an electronic waste (e-waste) dismantling area (n = 175) and two reference areas (rural, n = 29 and urban, n = 17) in southern China. Bis(2-chloroethyl) phosphate [BCEP, geometric mean (GM): 0.72 ng/mL] was the most abundant Cl–mOP, and diphenyl phosphate (DPHP, 0.55 ng/mL) was the most abundant NCl–mOP. The GM concentrations of mOPs in the e-waste dismantling sites were higher than those in the rural control site. These differences were significant for BCEP (p < 0.05) and DPHP (p < 0.01). Results suggested that e-waste dismantling activities contributed to human exposure to OPs. In the e-waste sites, the urinary concentrations of bis(2-chloro-isopropyl) phosphate (r = 0.484, p < 0.01), BCEP (r = 0.504, p < 0.01), dibutyl phosphate (r = 0.214, p < 0.05), and DPHP (r = 0.440, p < 0.01) were significantly increased as the concentration of 8-hydroxy-2′-deoxyguanosine (8-OHdG), a marker of DNA oxidative stress, increased. Our results also suggested that human exposure to OPs might be correlated with DNA oxidative stress for residents in e-waste dismantling areas. To our knowledge, this study is the first to report the urinary levels of mOPs in China and examine the association between OP exposure and 8-OHdG in humans.

“…Due to their health effects, OP residues in crops, food, and food by-products especially residues exceeding the Maximum Residue Levels (MRL) can be a threat to health and international trade (Zhang et al, 2008). Consequently, pesticide monitoring programmes have been implemented…”

“…There are no national MRLs in Kenya, and this could lead to inadequate monitoring of pesticide residues in vegetables. Failure to follow GAP may lead to exposure of consumers to higher than maximum allowable limits, which may lead to adverse health effects (Zhang et al, 2008). In addition, MRL exceedances may impede trade leading to reduced export of the vegetable produce to the EU and other trade partner countries .…”

SummaryHerein we present a survey of the literature covering the development of molecular imprinting science and technology over the years 2004 to 2011. In total, 3779 references to the original papers, reviews, edited volumes and monographs from this period are included, along with recently identified uncited materials from prior to 2004 which were omitted in the first instalment of this series covering the years 1930 to 2003. 1 In the presentation of the assembled references, a section presenting reviews and monographs covering the area is followed by sections describing fundamental aspects of molecular imprinting including the development of novel polymer formats. Thereafter, literature describing efforts to apply these polymeric materials to a range of application areas is presented. Current trends and areas of rapid development are discussed.2
