What are pesticide birth defects?
Pesticide birth defects are aberrations that result in physical and mental disorders. Pregnant women must remember about the situations that can lead to pesticide exposure. Pesticide birth defects appear as a result of exposures in agriculture, gardening, and homes. Scientists affirm that in some cases pesticides increase the likelihoods of pesticide natal defects up to 450 %.
Pregnancy and pesticide birth defects
Exposure to pesticides during pregnancy bears considerable risks to the fetus. Now researchers find increased rates of pesticide birth defects and miscarriages. Organophosphate exposure during pregnancy may lead to early childbirth and low birth weight. Early birth is an important cause of infant mortality. Preterm birth and low birth weight pave the way to future cognitive problems, risk of heart disease and asthma. Organophosphates are associated with significant IQ loss in children.
Pesticide birth defects and children
Pregnancy beginning in spring and summer is linked to high rates of pesticide birth defects because of increased levels of chemicals in surface and ground waters. Infants are at risk of exposure to organophosphates and synthetic pyrethroids that lead to physical and mental delay, respiratory deformities, changes of cardiovascular system, musculoskeletal defects, obesity, aberrations of the menstrual cycle, and undeveloped secondary sex features. Researchers also point to the association between birth defects and chlorophenoxy herbicides.
Nervous system and pesticide birth defects
Scientists relate autism to the environmental pollution. Researchers affirm that infants born with high levels of organochlorines in the cord blood have small head circumference. Conceived in the spring babies are at higher risk for pesticide genetic defects such as Down syndrome. Researchers discovered high concentrations of endosulfan and lindane in placentas of newborns in some areas. They relate these pesticides to congenital neural tube defects with failure of spinal cord fusion, known as spina bifida, as well as to anencephaly.
Reproductive system and pesticide birth defects
Researcher demonstrated a relationship of professional exposure to insect repellents with an increased risk of hypospadias. Hypospadias is a hereditary defect in which the urethra opening is on the penis underside. Researchers also established an association between chemical contamination in pregnancy and the risk of cryptorchidism. These pesticide birth imperfections are related to high concentrations of organochlorines in the breast milk. These conditions may lead to disorders of sperm production later in life and increase the risk of testicular cancer.
Atrazine and pesticide natal defects
Researchers discovered that children conceived during the season of atrazine spraying are at an increased risk of pesticide genetic defects. Doctors diagnose gastroschisis more frequently among infants conceived when atrazine levels are increased. In gastroschisis the infant’s intestines stick out because of a defect of the umbilical cord and grow outside the body.
Chlorpyrifos and pesticide natal defects
Chlorpyrifos provokes serious birth defects. Chlorpyrifos is applied in agriculture and indoors against termites and fleas. Women living and working in areas with high chlorpyrifos use are at risk to give birth to children with defects of brain, eyes, ears, palate, teeth, heart, genitalia, and feet.
Glyphosate and pesticide genetic defects
Glyphosate damages embryonic growth. Glyphosate is responsible for miscarriages, stillbirths, infertility, cyclopia, and cancer. Glyphosate disrupts aromatase activity that is essential for reproduction, sex hormone synthesis, sex differentiation, and bone growth. Glyphosate makes cell membranes more penetrable and quickens apoptosis and necrosis.
