Endocrine Disruptors - National Institute of Environmental
Endocrine disruptors are found in many everyday products, including some plastic bottles and containers, liners of metal food cans, detergents, flame retardants, food, toys, cosmetics, and pesticides. Some endocrine-disrupting chemicals are slow to break-down in the environment. That characteristic makes them potentially hazardous over time.
Contamination of Groundwater | U.S. Geological Survey
Pesticides and fertilizers applied to lawns and crops can accumulate and migrate to the water table. Leakage from septic tanks and/or waste-disposal sites also can introduce bacteria to the water, and pesticides and fertilizers that seep into farmed soil can eventually end up in water drawn from a well.
Inert Ingredients Overview and Guidance | US EPA
An inert ingredient generally is any substance (or group of similar substances) other than an active ingredient that is intentionally included in a pesticide product. Examples of inert ingredients include emulsifiers, solvents, carriers, aerosol propellants, fragrances and dyes. InertFinder allows users to search for inert ingredients by
Endocrine Disruptors - Biological Diversity
ENDOCRINE DISRUPTORS. Just say no to wildlife on drugs — biology-altering chemicals, that is. Thanks to pesticides, pharmaceuticals, plasticizers, cleaning agents, cosmetics, antibiotics, contraceptives, veterinary and illicit drugs, sunscreen and caffeine introduced into waterways and aquatic habitats, endangered species are ever more exposed to chemicals that disrupt the function of their
Occurrence and treatment of contaminants of
According to the review, pharmaceuticals, endocrine-disrupting chemicals, personal care products, pesticides, per- and polyfluoroalkyl compounds, and microplastics were found in conventional and non-conventional water resources. Most conventional water resources, such as rivers, streams, lakes, wells, and boreholes, are used as drinking water
- What are the subclasses of pesticides?
- The chemical composition of pesticides, such as dipyridyl, organochlorines, benzoic acid, organophosphates, pyrethroids, carbamates, phenyl alkanoate, triazines, phenyl amides, and phthalimides, is another approach to divide them into subclasses (Jayaraj et al. 2016).
- Are pesticides causing heavy agricultural activity?
- According to a study by Belenguer et al. (2014), the presence and concentration of pesticides such as prochloraz, clofenvinphos, pyriproxyfen, imazalil,and dichlofenthionhave been linked to the region's heavy agricultural activity (Belenguer et al. 2014).
- Why are plasticizers considered environmental pollutants?
- Plasticizers that include phthalates show a tendency to persist in the environment and bioaccumulate in organisms. These are the main factors that contribute to their inclusion in lists of priority pollutants (Schwarzbauer et al. 2002). Other plasticizers, phosphates and sulfonamides are also included in the category of environmental pollutants.
- How many pesticides are in surface water and groundwater?
- Increased concentrations of chemicals derived from pesticides have been discovered in both surface water and groundwater due to their widespread usage. The research discovered 58 samples of surface water and groundwater to contain 150 pesticides and their metabolic byproducts (Reemtsma et al. 2013).
- Are pesticide metabolites found in water matrices?
- The variability in the runoff specimens to various pesticide applications in sparsely populated urban areas; pesticide metabolites were found in ground and surface water (Reemtsma et al. 2013). Numerous metabolites discovered in water matrices indicate that pesticide use is every day in urban areas (Gallé et al., 2020, Reemtsma et al., 2013).
- How many pharmaceuticals are in a multiclass EDC?
- Of the 18 multiclass EDCs, sample analyses revealed the occurrence of seven pharmaceuticals, five hormones, two plasticizers, and one pesticide in tap water samples (Fig. 3).
