“…153 An ecological study determined that women in a rural region of Iowa with increased levels of triazine, metolachlor, and cyanazine herbicides in the drinking water had an elevated risk of delivering an infant with intrauterine growth retardation compared with women in other parts of the state. 154 A study based in France reported that atrazine levels in municipal drinking water throughout pregnancy were not associated with increased risk of delivering an SGA infant but that the risk of delivering an SGA infant increased when the third trimester occurred in whole or in part during the period of May through September, when atrazine levels typically peak. 155 …”

Pesticides are a collective term for a wide array of chemicals intended to kill unwanted insects, plants, molds, and rodents. Food, water, and treatment in the home, yard, and school are all potential sources of children’s exposure. Exposures to pesticides may be overt or subacute, and effects range from acute to chronic toxicity. In 2008, pesticides were the ninth most common substance reported to poison control centers, and approximately 45% of all reports of pesticide poisoning were for children. Organophosphate and carbamate poisoning are perhaps the most widely known acute poisoning syndromes, can be diagnosed by depressed red blood cell cholinesterase levels, and have available antidotal therapy. However, numerous other pesticides that may cause acute toxicity, such as pyrethroid and neonicotinoid insecticides, herbicides, fungicides, and rodenticides, also have specific toxic effects; recognition of these effects may help identify acute exposures. Evidence is increasingly emerging about chronic health implications from both acute and chronic exposure. A growing body of epidemiological evidence demonstrates associations between parental use of pesticides, particularly insecticides, with acute lymphocytic leukemia and brain tumors. Prenatal, household, and occupational exposures (maternal and paternal) appear to be the largest risks. Prospective cohort studies link early-life exposure to organophosphates and organochlorine pesticides (primarily DDT) with adverse effects on neurodevelopment and behavior. Among the findings associated with increased pesticide levels are poorer mental development by using the Bayley index and increased scores on measures assessing pervasive developmental disorder, inattention, and attention-deficit/hyperactivity disorder. Related animal toxicology studies provide supportive biological plausibility for these findings. Additional data suggest that there may also be an association between parental pesticide use and adverse birth outcomes including physical birth defects, low birth weight, and fetal death, although the data are less robust than for cancer and neurodevelopmental effects. Children’s exposures to pesticides should be limited as much as possible.

“…The bio-accumulation of atrazine into the food chain (animals and human beings) leads to various notorious health hazards and environmental effects. The most serious side effects of atrazine pollution are endocrine disruptor, teratogen, retarding sexual and embryo development, variations in pubertal growth in the living things (Chapin et al 1996;Munger et al 1997;Kniewald et al 2000 Atrazine is found in the ground water at several places of the world (Ritter 1990;Southwick et al 2002;Phyu et al 2004;Thorpe and Shirmohammadi 2005;Gilliom et al 2006;Sanagi et al 2015). The scientists, governments and nongovernmental organizations (NGOs) are very much concerned to this herbicide.…”

Atrazine organic pollutant has been found in several water resources of the world. It is highly toxic and carcinogenic in nature. Atrazine is removed by adsorption on iron composite nanoparticles. The composite nanoparticles were synthesized, analyzed and applied for atrazine uptake from water. Residual atrazine was monitored by gas chromatography-mass spectrometry. The maximum atrazine removal (95 %) was achieved using contact time 30.0 min, concentration 30.0 lg/L, pH 7.0, dose 2.5 g/L and temperature 20.0°C. The adsorbent was selective for atrazine adsorption. The results obeyed Langmuir, Freundlich, Temkin and Dubinin-Radushkevich isotherms. DG°values were -6.05, -6.11 and -6.15 kJ/mol at 20, 25 and 30°C temperatures, respectively. The value of DS°w as -2.45 9 10 -3 kJ/mol K. It showed decline in entropy of atrazine uptake. The adsorption followed pseudo-second-order kinetics. The adsorption mechanism was liquid film diffusion. The proposed adsorption method is inexpensive, fast and reproducible. It can be used to remove atrazine from any water sample/source.

“…Although the radiokbelled PQ is found in the placenta and the fetus 0.5 h after the intravenous administration to pregnant rats, PQ is considered not a teratogen (Bus et al, 1975;Selypes et al, 1980;Ingebrigtsen et al, 1984). But the drinking water supplies contaminated with herbicides elevate rates of intrauterine growth retardation (IUDR) (Munger et al, 1997) and is associated with significant reductions in gastrointestinal and pancreatic tissue weights (Xu et al, 1994).…”
