CONTAMINATION of the environment by persistent pesticides is universal1–11. Residues have been found in a variety of animals in the Antarctic12,15; analysis of two samples of glacial ice from the vicinity of Byrd Station (80° S, 1190° W) gave negative results13, but traces of dieldrin and DDT have been found in biota on Signy Island in the Antarctic, 3,000 miles from McMurdo Sound. The ecological implications of these contaminants have been discussed14,15. 
Organochlorine pesticides in the atmosphere of the Southern Ocean and Antarctica, January–March, 1990
Abstract Chlorinated pesticides in air were measured from the Greenpeace ship Gondwana between New Zealand and Ross Island, January–March, 1990. Geometric mean concentrations (pg m −3 ) were: α and γ

DDT is a useful model compound for studying the circulation of a toxic pollutant in the global environment1,2. An understanding of this process could in future be related to potentially more
Chemical change in Antarctica—Significance? A perspective
Abstract The bitter confrontations of 20–25 years ago between a small environmental science community and several industries manufacturing chlorinated hydrocarbons are now only an historical footnote
Dynamics of Pesticide Residues in the Environment
Residues of pesticides or their degradation products have been reported in a wide variety of environmental samples. The concentrations of compounds of one particular group of pesticides, the
Accumulation of Chemicals in the Hydrosphere
When considering accumulations of chemicals in the environment, among the first things that usually come into our minds are the concentrations and accumulations of various pesticides in aquatic food
Deposition of organochlorine pesticides into the surface snow of East Antarctica.
Backward air trajectory analysis showed that the air masses at the sampling sites came mainly from the Indian and Atlantic Oceans and over the Antarctic continent, indicating that the OCPs were subjected to long-range atmospheric transport and were deposited in the surface snow.
DDT in the Biosphere: Where Does It Go?
The analysis suggests that mere good fortune has protected man and the rest of the biota from much higher concentrations, thus emphasizing the need to determine the details of the movement of DDT residues and other toxins through the biosphere and to move swiftly to bring world use of such toxins under rational control based on firm knowledge of local and worldwide cycles and hazards.
Polychlorinated Biphenyls and Organochlorine Pesticides in Great Lakes Precipitation
Abstract Snow samples from the winter of 1975-6 and rain samples (seven locations) from the period May-November, 1976, were collected from around the Canadian side of the Great Lakes. All were
Chlordane compounds residues in Weddell seals (Leptonychotesweddelli) from the Antarctic
Weddell seal samples taken from the Antarctic have been found to be contaminated with chlordane compounds, and a probable explanation for their occurrence in the Antarctic is an airborne transport.
Atmospheric pollution by persistent organic compoumds: Monitoring with pine needles
Abstract Pine needles (P. sylvestris ) were used to observe the geographic and temporal patterns of atmospheric organic pollutants. Samples collected in 1986 (growth years 1984–1986) across Europe


Organochlorine Pesticides in Antarctica
The first reports of organochlorine pesticides in wildlife in the vicinity of the US Antarctic base at McMurdo Sound suggested that local human activity might be responsible. Measurements of samples
DDT Residues in Pacific Sea Birds: a Persistent Insecticide in Marine Food Chains
Analysis of collections of birds, fish and invertebrates from Pacific Ocean localities indicates that DDT is also a component of marine ecosystems and that pelagic species may accumulate high concentrations of DDT residues.
Pesticide Residues in the Irish Environment
An investigation of the occurrence and distribution of residues of organic mercury and the organic chlorine insecticides, lindane (γ-BHC), aldrin, dieldrin and pp′-DDT, in the Irish environment was undertaken and the findings should be of particular interest.

To explain the anti-tumour effect of RNA it is not necessary to suggest that changes it induces are preserved for a long time, but a decrease over a short period in the ability of implanted cells to autonomous growth simil:ir to short-time changes induced in bacteria by specific RNA from the outside is sufficient for protective mechanisms of the animal to perform their function.
