Sensitivity of freshwater periphytic diatoms to agricultural herbicides [PDF]

, 2009
The biomonitoring of pesticide pollution in streams and rivers using algae such as diatoms remains difficult. The responses of diatomcommunities to toxic stress in streamwater are disturbed by the variations of environmental parameters.

Differential herbicide persistence and shifts in soil bacterial communities in Alfisol and Inceptisol

Sains Tanah: Journal of Soil Science and Agroclimatology
Weeds significantly reduce crop yields and promote herbicide use, accounting for 80% of agricultural pesticides. However, herbicide persistence and toxicity adversely affect soil microbial communities, impacting soil health and productivity.

Effects on herbicides on hedgerow biodiversity [PDF]

, 2008
Low dosages of herbicides may reduce the number of flowers on non-target plants. Effect of herbicides on flowering and on pollen and nectar production are relevant end-points for effect assessment on non-target species.

Nanozymes at the Bio‐Nano Interface: From Synthesis, Defect Engineering, Catalytic Behavior in Biological Microenvironments, and Biosafety Implications

Advanced Materials Interfaces, EarlyView.
Nanozymes (NZs) have emerged as versatile artificial enzymes with tunable catalytic properties driven by atomic coordination, defect engineering, and surface chemistry. This review presents a bio–nano interface framework linking synthesis strategies, structural design, and catalytic behavior within complex biological microenvironments.

Allelopathy: an eco-friendly approach to control palmer amaranth using allelopathic sweetpotato

Frontiers in Agronomy, 2022
Palmer amaranth (PA) is one of the major weeds in sweetpotato reducing its quantity and quality. The widespread and repeated use of chemical herbicides has led PA to develop resistance for such chemicals. In addition, chemical herbicides are incompatible

Climate Change Threatens Micronutrient Density of European Winter Wheat

Advanced Science, EarlyView.
Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates

Organic meat products contaminated with carcinogenic herbicide

BMJ, 2002
A storage depot in east Germany has been identified as the source of several hundred tonnes of organic animal feed contaminated with the herbicide nitrofen. Before the reunification of Germany in 1990, the depot, in Mecklenburg-West Pomerania, was used for storing the herbicide.

Bioenergy Cropping Reduces the Spatiotemporal Scaling of Soil Bacterial Biodiversity

Advanced Science, EarlyView.
Consistent with patterns observed in plant and animal communities, soil bacterial communities exhibit significant species–time–area and phylogenetic–time–area relationships independent of nested structure. Bioenergy cropping significantly reduces the spatiotemporal scaling rates, particularly in sandy loam soils.
