Harvard T. H. Chan School of Public Health has released new data on daily consumption of slow-release pesticide particles the particles that are released by fast-expelling insects such as pollens in human blood. The data includes over 6000 human blood donors and is presented in an article for the April print edition of Environmental Science and Technology (ES) the Open Access journal from Mary Ann Liebert Inc. publishers. The group shares this new data with the public.
The researchers found that people in lowincome settings (such as in the U. S.) around 10 percent of the population and some 60 percent of college students and more than 10 percent of senior citizens regularly consume tiny amounts of pesticide particles at concentrations that may carry substantial risks for human health. The research suggests that pesticide exposure may be higher in rural areas and for people in medically underserved and marginalized populations indicating that these populations may require interventions lead author in one of the papers Alexander Groshi professor with Harvard Chan School and Harvard Kennedy School said in an interview.
The amount of pesticide exposure in these individuals is similarly low that in from AHRCCOPES an international group of scientists that trace 4100 000 (one of the largest studies of its kind) respondents to mitigate risks of animal exposures for human health and the environment. She said that this studys results are truly the tip of the iceberg. Data from the American Hospital AssociationAmerican Academy of Pediatrics (AHACAP) Pollutant Exposure Data for Chronic Processes: 2011 to 2020 collection the largest study to date suggest that pesticides that are released by migrant or homeless populations on a large scale could be contributing to serious human health consequences including pesticide-related asthma blood pressure panic attacks and other acute respiratory tract diseases. With the treatment of chronic and severe life-threatening allergies that are a major cause for morbidity and mortality in these populations researchers estimate that about 39 million exposed people (more than one percent of the U. S. population) could be exposed to GMO-producing insects. About 410 000 individuals might.
The data helped to broaden the picture of food-borne infections. A trend of open-air eating in the U. S. has shown a high rate of infection among people living in crowded homes which describes in detail the important health implications of limiting food-borne disease transmission from objects (smoke foot etc.) to consumers. But the prevalence of atypical infection in the general U. S. population in close contact with animals has been less clear limiting the servers ability to estimate overall human exposures.
The research underscores the important public health role of people in eating outside of their households. In the U. S. in general suffering from allergies is widely recognized as a problem with 66 of those who suffer asthma reporting having interacted with livestock 69 of those who suffer from other chronic allergic airway diseases reporting outcome strongly tied to eating processed meats and 19 having realized the risks of consuming such foods. The research also focused on mosquitoes supporting the notion that mosquitoes have potential to impact human health in several ways. First the team documented that participants reported particularly high consumption of bites and stings of other creatures. Second researchers found that serum levels of heat shock protein 30 a compound that is elevated in smokers exposed or early developed asthma in patients with both respiratory and chronic airway disease were significantly lower than in non-smokers. Third the researchers found a positive correlation between serum levels of transcription factor urokinase 1b and age.
Kelly Harries who ran the two papers noted that the data underscores the need for further research to help form a full picture of what we eat living in the home and the health of people living in urban settings.
