Using passive samplers to assess bioavailability, toxicity, and reactivity of hydrophobic organic chemicals (HOCs)
… was used to infer in situ degradation rates of dichlorodiphenyltrichloroethane (DDT), which in the sediments of a freshwater lake were found to be between 0.09 and 0.9 d-1. A second mathematical model describing the kinetics of exchange between passive samplers and water was also developed, …

Assessing the Phytoextraction of Organic and Inorganic Pollutants From Point Pelee National Park, Ontario and Iqaluit, Nunavut
… a National Park that is highly contaminated with dichlorodiphenyltrichloroethane (DDT), dieldrin, arsenic and lead from historical agricultural and residential pesticide applications. Six planted native grass and weed species, and several naturally occuring species were analyzed for DDT, dieldrin, …

Development of multi-residue and selective methods for the ultra-sensitive determination of endocrine disrupting chemicals in aqueous samples
… pollution of the surrounding environment with dichlorodiphenyltrichloroethane (DDT) [1]. From that time, public awareness was born and grew ever since. Only three decades later, a new disturbing event was signalled in an article by Theo Colborn [2]. He described the deleterious influence that …

Numerical Modeling of Steam Flushing for Removal of Dense Nonaqueous Phase Liquids
… and a mixture of monochlorobenzene (MCB) and dichlorodiphenyltrichloroethane (DDT) perched on a barrier layer were simulated with a nonisothermal multiphase, multicomponent model (CompSim) to both test the model’s ability to simulate DNAPL removal by steam flushing and to examine the effects …

Use of magnetic nanoparticles for wastewater treatment
… (PAHs), poly chlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane (DDT) and heavy metals like mercury, lead and manganese are among the ubiquitous trace contaminants of marine and freshwater systems. Presence of these contaminants raise concerns as small quantities of the organic …

Molecular docking and geographical information systems as tools to assess the potential impact of veterinary medicines on non-target organisms and the environment
… ethinylestradiol, two known xenoestrogens dichlorodiphenyltrichloroethane (DDT) and bisphenol A (BPA), the antioestrogen breast cancer treatment tamoxifen and 15 VMs using Auto Dock 4. Based on the results of this work, four VMs were identified as being possible xenoestrogens or …

Nutritional and toxicological studies on New Zealand mutton bird meat (Puffinus griseus) : a thesis submitted in partial fulfilment of the requirements for the degree of Master of Science at Lincoln University
… human consumption. Persistent organochlorine, dichlorodiphenyltrichloroethane (DDT) and their metabolites, and aldrin and lindane were also measured.Twenty bird carcasses were purchased in both 2006 and 2007 from a local source. Meat samples from the pectoral muscle of two carcasses were pooled …

Examining the Experiences of Smallholder farmers in Malawi towards Farm Input Subsidies
… of Blantyre. We could apply pesticides such as Dichlorodiphenyltrichloroethane (DDT) to prevent pests from attacking our crops to enhance vegetable production. No one could pronounce this name in our village, and everybody opted for its abbreviation. The pesticide is a general name that refers …

Genome-wide sequencing and an open reading frame analysis of DDT susceptible (91-C) and resistant (91-R) Drosophila melanogaster laboratory populations
DDT resistance in the Drosophila melanogaster resistant (91-R) and susceptible (91-C) fly lines has been previously examined for differential expression of transcripts and proteins. Here I present the first whole genome sequencing analysis of the 91-R and 91-C fly lines to identify structural …
