Veterinary aspects of insecticides: Organochlorines

New Zealand Veterinary Journal, 1971
Abstract Extract Many countries are in the process of phasing out large-scale use of organochlorine insecticides. Reasons for this policy can be summarized in terms of resistance, residues, and pollution, all of which stem from the property common to most organochlorines—persistence in the environment.

Premature delivery and organochlorine compounds: Polychlorinated biphenyls and some organochlorine insecticides

Environmental Research, 1982
Abstract Some organochlorine compounds (OCC), DDT and metabolites, γ-HCH, dieldrin, heptachlor epoxide and polychlorinated biphenyls were assessed in the serum of 17 women with premature delivery (PD) and 10 women with normal, third-trimester pregnancy.

Dynamics of Organochlorine Insecticides in Vertebrates and Ecosystems

Nature, 1967
The dynamics of the diffusion of organochlorine pesticides in ecosystems can be described by a model based on the theory of sets. The model shows that research which relies on measurement of the pesticide at different periods of time can lead to misleading conclusions.

ORGANOCHLORINE INSECTICIDES IN SUBSTANTIA NIGRA IN PARKINSON'S DISEASE

Journal of Toxicology and Environmental Health, Part A, 2000
The concentrations of organochlorine (OC) compounds in the substantia nigra (SN) were compared in Parkinson's disease (PD) with concentrations in brain from cortical Lewy body dementia (CLBD), Alzheimer's disease (AD), and nondemented nonparkinsonian controls (CON).

Organochlorine insecticide residues in wild birds in Britain

Journal of the Science of Food and Agriculture, 1967
AbstractOrganochlorine insecticide residues in a wide range of wild birds and their eggs from all over Britain have been determined by gas‐liquid chromatography and paper chromatography. Higher residues were found in predatory species than in omnivorous or herbivorous species.

Electronic structure of pesticides: 1. Organochlorine insecticides

Journal of Electron Spectroscopy and Related Phenomena, 2011
The electronic structures of six organochlorine insecticides: g-lindane (I), aldrin (II), dieldrin (III), DDD(IV), DDE (V) and DDT (VI) have been investigated by UV photoelectron spectroscopy (UPS), quantum chemical calculations and comparison with molecular modelling studies.

Storage of organochlorine insecticides in adipose tissue of ugandans

Bulletin of Environmental Contamination and Toxicology, 1974
In the framework of a WHO — International Agency Program for Research on Cancer, people from five African, three Asian, and two South American countries were studied for the storage level of organochlorine insecticide storage in the adipose tissue of Ugandans.

Induction of Macrophage Apoptosis by an Organochlorine Insecticide Acetofenate

Chemical Research in Toxicology, 2009
Acetofenate (AF) is a widely used insecticide in China and other regions of southeastern Asia. A previous study showed that AF caused adverse developmental effects in zebrafish. Macrophages, which play a key role in inflammation, host defense, and reactions against a spectrum of autologous and foreign invaders, are crucial for innate immunity. However,

Organochlorine Insecticides in Mudflats of Hong Kong, China

Archives of Environmental Contamination and Toxicology, 2005
Organochlorine (OC) insecticides were measured in different environmental compartments (including seawater, sediment, and biota) at six sites within the Mai Po Marshes Nature Reserve (MPMNR) and at one site in A Chau (AC) in Hong Kong in June 2002 (wet season) and January 2003 (dry season).
