Sorption and resistant desorption of atrazine in typical Chinese soils

Abstract

Atrazine is one of the most commonly used herbicides and is produced and used in large quantity worldwide. In the present study, the sorption and desorption of atrazine in five typical Chinese soils were examined. The sorption of atrazine followed the conventional linear isotherm reasonably well, indicating that sorption was driven largely by hydrophobic partitioning into soil organic matter. However, strong resistant desorption (desorption hysteresis) was observed for all five soils. The desorption data could be well modeled with several biphasic sorption/desorption isotherms that include a quasi-Langmuir or a Freundlich term to account for the nonlinear sorptive property associated with the desorption-resistant fraction. Experimental observations in the present study are consistent with studies reported in the literature and with our previous work with other hydrophobic organic compounds and different sorbents. These observations suggest that physical entrapment within porous soil matrix was likely the predominant mechanism controlling the observed desorption resistance. The unique characteristics associated with the resistant-desorption fraction have important implications for risk assessment of atrazine-contaminated soil/se...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
