TLDR
Glyphosate will likely remain the most widely applied pesticide worldwide for years to come, and interest will grow in quantifying ecological and human health impacts, according to published global pesticide use data.Abstract:
Accurate pesticide use data are essential when studying the environmental and public health impacts of pesticide use. Since the mid-1990s, significant changes have occurred in when and how glyphosate herbicides are applied, and there has been a dramatic increase in the total volume applied. Data on glyphosate applications were collected from multiple sources and integrated into a dataset spanning agricultural, non-agricultural, and total glyphosate use from 1974–2014 in the United States, and from 1994–2014 globally. Since 1974 in the U.S., over 1.6 billion kilograms of glyphosate active ingredient have been applied, or 19 % of estimated global use of glyphosate (8.6 billion kilograms). Globally, glyphosate use has risen almost 15-fold since so-called “Roundup Ready,” genetically engineered glyphosate-tolerant crops were introduced in 1996. Two-thirds of the total volume of glyphosate applied in the U.S. from 1974 to 2014 has been sprayed in just the last 10 years. The corresponding share globally is 72 %. In 2014, farmers sprayed enough glyphosate to apply ~1.0 kg/ha (0.8 pound/acre) on every hectare of U.S.-cultivated cropland and nearly 0.53 kg/ha (0.47 pounds/acre) on all cropland worldwide. Genetically engineered herbicide-tolerant crops now account for about 56 % of global glyphosate use. In the U.S., no pesticide has come remotely close to such intensive and widespread use. This is likely the case globally, but published global pesticide use data are sparse. Glyphosate will likely remain the most widely applied pesticide worldwide for years to come, and interest will grow in quantifying ecological and human health impacts. Accurate, accessible time-series data on glyphosate use will accelerate research progress.read more

Glyphosate Induces Metaphase II Oocyte Deterioration and Embryo Damage by Zinc Depletion and Overproduction of Reactive Oxygen Species
Zeina A. Yahfoufi,David Bai,Sana N. Khan,Charalampos Chatzicharalampous,Hamid Reza Kohan-Ghadr,Robert T. Morris,Husam M. Abu-Soud +6 more
TL;DR: This work shows for the first time that glyphosate exposure impairs metaphase II mouse oocyte quality via two mechanisms: disruption of the microtubule organizing center and chromosomes such as anomalous pericentrin formation, spindle fiber destruction and disappearance, and defective chromosomal alignment and substantial depletion of intracellular zinc bioavailability and enhancement of reactive oxygen species accumulation.

Title: Low concentrations of glyphosate in water and sediment after direct over-water application to control an invasive aquatic plant.
TL;DR: The direct, over-water application of glyphosate with AquasurfⓇ to control invasive P. australis did not reach concentrations deemed to pose toxicological concern to aquatic biota by the Canadian Council of Ministers of the Environment, and concentrations in water returned to pre-treatment levels.

Bioconcentration of glyphosate in wetland biofilms.
Laura Beecraft,Rebecca C. Rooney +1 more
TL;DR: The role of biofilms is demonstrated in improving wetland water quality by removing contaminants like glyphosate, but also as a potential exposure route to higher trophic levels via consumption due to bioconcentration of pesticides.

TL;DR: This multi-omics approach provides evidence for subtle metabolic effects of Roundup® LB plus under the conditions applied, and identifies some effects on the functional level.

The rise of glyphosate and new opportunities for biosentinel early-warning studies.
Zoe Kissane,Jill M. Shephard +1 more
TL;DR: There is a strong case for the recognition of glyphosate as an emerging organic contaminant and substantial potential exists for collaborative research among ecologists, toxicologists, and chemists to quantify the impact of glyphosate on wildlife and to evaluate the role of biosentinel species in a preemptive move to mitigate downstream impacts on people.

TL;DR: One of the first specialized agencies of the United Nations to become active, the Food and Agriculture Organization (FAO) as discussed by the authors has elicited interest beyond the specialized field of agricultural economists.

Glyphosate: a once-in-a-century herbicide.
TL;DR: The use of this virtually ideal herbicide is now being threatened by the evolution of glyphosate-resistant weeds, and adoption of resistance management practices will be required to maintain the benefits of glyphosate technologies for future generations.

TL;DR: GBHs are the most heavily applied herbicide in the world and usage continues to rise; Worldwide, GBHs often contaminate drinking water sources, precipitation, and air, especially in agricultural regions and regulatory estimates of tolerable daily intakes for glyphosate in the United States and European Union are based on outdated science.
