New Report Shows Pesticide Exposure Associated with Certain Cancers

(Beyond Pesticides, July 6, 2010) A review report published last Friday highlights that some research studies indicate that pesticide exposure either prior to conception, during pregnancy or during childhood appears to increase the risk of childhood cancer, with maternal pesticide exposure during pregnancy being most consistently associated with childhood cancer. Furthermore, the report notes that […]

Nonpersistent Pesticides Found in Umbilical Cord Blood

(Beyond Pesticides, June 17, 2010) Researchers have found detectable levels of common household pesticides in the majority of umbilical cord blood of babies born at an urban hospital. The study looks at concentrations of organophosphate (OP), carbamate, pyrethroids, and organochlorine pesticides in samples of umbilical cord blood taken from newborns delivered at the Johns Hopkins […]

USGS Finds Atrazine Herbicide Adversely Affects Fish Reproduction

(Beyond Pesticides, June 1, 2010) Atrazine, one of the most commonly used herbicides in the world, has been shown to affect reproduction of fish at concentrations below U.S. Environmental Protection Agency’s (EPA) water-quality guideline, according to a new U.S. Geological Survey (USGS) study. “Concentrations of atrazine commonly found in agricultural streams and rivers caused reduced […]

Study Finds that Childhood Exposure to Insecticides Associated with Brain Tumors

(Beyond Pesticides, January, 21, 2009) A new study concludes that exposures during pregnancy and childhood to insecticides that target the nervous system, such as organophosphates (OPs) and carbamates, are associated with childhood brain tumors. The researchers hypothesize that this susceptibility might be increased in children with genetic variations that affect the metabolism of these chemicals. […]

Insect repellents linked to genital defects in baby boys

THE GUARDIAN, UNITED KINGDOM Tuesday, December 1, 2009 British Medical Journal Women who use insect repellents during the first three months of pregnancy are more likely to give birth to baby boys with a genital defect, according to researchers. Insecticides used in gardening and agriculture may also be linked to genital malformations in boys. What […]

Pesticide-Chemical Mixtures Affect Sex Organ Development

(Beyond Pesticides, July 28, 2009) A new study by researchers at the National Food Institute, Technical University of Denmark shows that exposure to a mixture of pesticides and other chemicals has a synergistic effect on the development of male sex organs. Synergy occurs when the effect of multiple chemicals is greater than the sum of […]

Sexual Disruption Linked to Environmental Pollutants

(Beyond Pesticides, January 22, 2009) A new English study has found that chemicals found in rivers and waste waters could be linked to male infertility. These chemicals, known as anti-androgens, block the action of the male sex-hormone testosterone and could impact the development of male reproductive organs in humans. The study entitled, “Statistical Modeling Suggests […]

Testicular Defects in Newborns Linked to Prenatal Chemical Exposure

(Beyond Pesticides, September 17, 2008) A new study has found a link between total chemical contamination in the bodies of pregnant women and the risk of cryptorchidism in their male babies. Mothers whose babies were born with the defect had the highest concentrations of persistent organic pollutants (POPs), mostly organochlorines like PCB and DDE, in […]

Researcher Shows Chemicals Alter Male Reproductive System

(Beyond Pesticides, February 19, 2008) Common household chemicals and widespread pollutants are changing male reproductive health and impacting sexual function, development and cancer rates of today’s generations and possibly their offspring, according to more than 15 years of research by a Colorado State University expert. For example, one study looking at sperm counts globally from […]
