Mary Jane Incorvia Mattina, William Iannucci-Berger, and Laure Dykas Chlordane Uptake and Its Translocation in Food Crops. (... the use of chlordane, an insecticide, was banned by the EPA [the United States Environmental Protection Agency] in 1988 due to the fact that it accumulates in the human body and can lead to digestive and nervous system disorders. Chlordane is a member of a group of pollutants known as persistent organic pollutants [POPs]--a group of chemicals characterized by extremely long residence in the environment after application. While the fact that chlordane remains in the environment long after it has been applied has been known for many years, this report was the first comprehensive study of the uptake of weathered soil residues of chlordane and its translocation throughout the tissues of food crops under both greenhouse and field conditions. In 1998, a variety of crops were planted in soil [in Connecticut, USA] that had been treated with chlordane in 1960. Roots and leaves from these crops were compared to the roots and leaves from crops that were grown in soil known not to be contaminated with chlordane. Results showed that chlordane was detected in the edible root tissue of the three root crops examined, carrots, beets, and potatoes. In the remaining crops chlordane was detected in the edible aerial tissue of spinach, lettuce, dandelion, and zucchini, whereas it was not detected in edible aerial tissue of tomatoes, peppers, and corn; trace amounts of chlordane were detected in the edible aerial tissue of bush beans and eggplant. The results of the study also indicated that the plants took up the chlordane much more through the soil than they did through the air. The implications of this study are that crops grown today may still contain chlordane even though chlordane may not have been applied to the soil in which they were grown for many years--from the text of the abstract and the article) Journal of Agricultural and Food Chemistry Volume 48, Number 5 (May 15, 2000): 1909-1915. **The complete text of this article is currently available through the Web site of Journal of Agricultural and Food Chemistry** Stephen C. Trombulak and Christopher A. Frissell Review of Ecological Effects of Roads on Terrestrial and Aquatic Communities. (... an article that reviews the scientific literature [published from the 1970's through the late 1990's] dealing with the effects of road construction, the use of roads, and the existence of roads of all types on surrounding land and water environments [both close to and substantial distances away from the road]. The authors found support for the general conclusion that they [roads] are associated with negative effects. Other keywords and phrases -- alteration of chemical environment, changes in use by humans, collision with vehicles, disruption of physical environment, fragmentation, habitat, hyperfragmentation, modification of animal behavior, mortality, spread of exotic species--from the text of the abstract and the article; see the extensive bibliography) Conservation Biology Volume 14, Number 1 (February 2000): 18-30. **An abstract of this article is currently available through the Web site of Conservation Biology** How to find the above journals, magazines, and other publications?
