The Distribution and Reactivity of Organochlorines in Estuaries
… further understanding of the behaviour of these organochlorines (OCs) in estuarine systems. Field surveys were conducted at UK estuarine (Humber, Clyde and Dee) and coastal locations. Sediments were analysed for OCs and a range of chemical and physicochemical properties (trace metals, organic …

A common and previously unknown ecological niche: the halorespiration of natural organochlorines in terrestrial soil and sediment
… and investigates the ability of natural organochlorines to serve as terminal electron acceptors for halorespiring organisms.

Ex ante assessment of secondary impacts of environmental regulation: case study--organochlorines in the Canadian pulp and paper industry
… assessed. The case study is the control of organochlorines in the Canadian pulp and paper industry via federal regulation of dioxins and furans and British Columbia's regulation of Adsorbable Organic Halogen (AOX). The thesis is founded upon the premise that sustainability must be an …

Immunological and hematological biomarkers for contaminants in fish-eating birds of the Great Lakes
… negative exposure-response relationship with organochlorines. There was no discernible association between contaminants and suppression of antibody-mediated immunity as measured by the sheep red blood cell antibody test and bursal mass. However, contaminant effects on bursal mass were …

Investigating the relationship between modifiable environmental risk factors and incidence of colorectal cancer: a community based study
… are tobacco/smoking, alcohol use, pesticides/organochlorines, and metal toxins. Following this study, it is imperative that recommendations are directed at a community level and relate to the assessment of potential non-nutritional modifiable environmental risk factors. Future research should …

Greening the invisible hand : how environmental non-governmental organizations (NGOs) succeed and fall in technology change
… they tried to diffuse reduced dioxins and other organochlorines from mills that bleach pulp for making white paper products. Totally chlorine-free (TCF) bleaching emerged as the cleanest bleaching technology in commercial use: it eliminated organochlorine water pollution. The Swedish …

Bald Eagle Foraging Habitats Along the James River in Missouri: Protection From Human Developments
… Fish samples collected were tested for 12 organochlorines and nine metals including lead and mercury. The sampling sites' micrograms/gram of fish of these contaminants were ranked using the Mann-Whitney U Test. There was no difference between the upper and the lower James River. The DDT …

Insecticide-Mediated Neurochemical and Behavioral Changes as Possible Predisposing Environmental Factors in Idiopathic Parkinson's Disease
… require Ca²⁺. Insecticidal toxicants, such as organochlorines and pyrethroids, which augment dopamine release and increase the maximal rate of dopamine uptake, may inundate the cytosol of nigrostriatal neurons with high concentrations of free dopamine, which has been shown by other researchers …

Toxicological consequences of pesticidal use in the Republic of South Africa
… cases (organophosphates 55%, carbamates 14%, organochlorines 4%) are with the exception of pyrethroids, also the chemicals most frequently formulated. Products containing these three chemical groups constitute only 41% of all formulated products, but are responsible for 73% of all …

Applications of aerobic and anaerobic bacteria in the fields of biological degradation of contaminants and biological wastewater treatment
… of the added polychlorinated chemicals. The organochlorines were analysed using reversed phase HPLC and FID-GC. When a change in the Chromatogram was detected the respective cultures were further analysed using ECD-GC and GC-MS. The results showed that the culutres grew under these …

Life on the edge: exploring the effects of urbanisation on the foraging ecology and ecotoxicology of caracals
… persistent organic pollutants (POPs), including organochlorines (OCs) such as PCBs and DDT and its metabolites, are extremely toxic, causing adverse effects on wildlife and human health. I tested blood and adipose tissues of caracals, with different diets utilising a range of natural and …
