An inexpensive 'dipstick' test for pesticides in foods
November 05, 2009Scientists in Canada are reporting the development of a fast, inexpensive "dipstick" test to identify small amounts of pesticides that may exist in foods and beverages. Their paper-strip test is more practical than conventional pesticide tests, producing results in minutes rather than hours by means of an easy-to-read color-change, they say.
The study is in the November 1 issue of ACS' Analytical Chemistry, a semi-monthly journal. John Brennan and colleagues note in the new study that conventional tests for detecting pesticides tend to use expensive and complex equipment and in some cases can take several hours to produce results. They cite a growing need for cheaper, more convenient, and more eco-friendly tests for pesticides, particularly in the food industry.
The scientists describe the development of a new paper-based test strip that changes color shades depending on the amount of pesticide present. In laboratory studies using food and beverage samples intentionally contaminated with common pesticides, the test strips accurately identified minute amounts of pesticides. The test strips, which produced results in less than 5 minutes, could be particularly useful in developing countries or remote areas that may lack access to expensive testing equipment and electricity, they note.

Pesticides: A Toxic Time Bomb in Our Midst by Marvin J. Levine (Author) Pesticide exposure has long been a cause for concern, and with good reason. Studies have shown that all persons, but especially children, pregnant women, farmers, farmworkers, and the elderly, may experience negative health effects from pesticide exposure. These effects may include acute poisoning, cancer, neurological damage, birth defects, reduced sperm count, suppressed immune systems, and reproductive and developmental harm. This book is a comprehensive examination of pesticide use, pesticide harm, and alternatives to harmful pesticides. Levine highlights the role of farming, because a substantial majority—70 percent or more annually—of pesticides are applied in agricultural uses, thereby making their way into the food chain and into the water supply. More than 20... |

Chemical Pesticides: Mode of Action and Toxicology by Jørgen Stenersen (Author) Environmental-friendliness, issues of public health, and the pros and cons of genetically-modified crops all receive regular coverage in the world's media. This, in turn, has led to increased questioning and investigation of chemical pesticides.Stenersen's concise introduction to chemical pesticides describes these compounds according to their biochemical mode of action, such as whether they are enzyme inhibitors, receptor ligands, or free radical generators. Chemical Pesticides provides answers to why pesticides are toxic to the target organism, how resistance develops, why pesticides are toxic to some organisms and not others. The book also discusses legal matters and concerns as well as potential environmental problems. |
