Water Resource Pollution by Herbicide Residues

Abstract

Herbicides are frequently used in the chemical control of weeds in various crops in Brazil and worldwide, so they are more frequently detected outside the application areas, contributing to the risk of environmental contamination. The importance of knowledge of the physicochemical properties of the environment and the pesticide used in the agricultural area is in order to understand its effects on terrestrial and aquatic ecosystems and the search for the prevention of future bioaccumulation potentials (bioconcentration and/or biomagnification) of molecules of pesticides in living nontarget organisms, minimizing their negative effects on the environment. The understanding of analytical techniques for measuring the quality of water resources as well as techniques for the remediation of contaminated water is essential to minimize the possible impacts caused by the application of pesticides to the environment.

Herbicides in Water Sources: Communicating Potential Risks to the Population of Mangaung Metropolitan Municipality, South Africa

“…These outcomes are expected to have an undesirable effect on aquatic life and human beings. There is evidence showing that exposure to simazine may cause weight changes as well as effects on the serum and thyroid gland [ 53 ]. Terbuthylazine may have an effect on carp growth rate, early ontogeny, and antioxidant enzyme [ 49 ].…”

Health effects of herbicides and its current removal strategies

“…Their mobility in soil is attributed to leaching and runoff that later contributes to agricultural non-point source pollution i.e. one of the major causes of reduced surface water quality [ 115 ]. With advances in research and development, the field is moving toward alternative technologies, as they are effective, green, and sustainable in addressing modern-day wastewater treatment [ 10 ].…”

“…Nonetheless, its use was examined on a small scale and the ecological and physiological properties of the extracts are not currently understood in the context of large-scale applications. Averting the arrival of chemical herbicide from water sources is another sustainable strategy to reduce the need for conventional remediation practices [ 115 ]. This can be done through mineralization using the microbial metabolism process, in which soil microorganisms consume herbicide compounds as a carbon source and turns them into NH 3 , H 2 O, and CO 2 via photolysis and hydrolysis in the presence of enzymes (e.g.…”

Facile Synthesis of Citric Acid Functionalized Fe3O4@Activated Carbon Magnetic Nanocomposite for Efficient Adsorption of Brilliant Green Dye from Wastewater

“…The major cause of this disaster is ever increasing industrialization, multiple-fold population growth and toxic chemical pollution of water bodies. Heavy metals, [1] radionuclides, [2] phenols, [3] pesticide, [4] herbicides, [5] antibiotics, [6] dyes, [7] and other pollutants are routinely emitted into the environment by several industries. The more dangerous of the pollutants indicated are dyes because they contain sophisticated unsaturated organic molecules that absorb visible light, reducing photosynthesis in aquatic environments.…”
