Global Zoning and Exchangeability of Field Trial Residues Between Zones: Are There Systematic Differences in Pesticide Residues Across Geographies?

James Nguyen, Carmen Tiu, Jane Stewart & David Miller
Mixed-effects models were used to evaluate the global zoning concept using residue data from a comprehensive database of supervised field trials performed in various countries and regions on a variety of pesticide–crop combinations. No statistically significant systematic differences in pesticide residues were found between zones among the pesticide uses examined. In addition, we conducted a simulation to assess the impact of using regional versus global datasets for calculating maximum residue limits (MRLs). The conclusion of...

Toxicity assessment of cobalt ferrite nanoparticles on wheat plants

J. López–Luna, M.M. Camacho–Martínez, F.A. Solís–Domínguez, M.C. González–Chávez, R. Carrillo–González, S. Martinez–Vargas, O.F. Mijangos–Ricardez & M.C. Cuevas–Díaz
Cobalt ferrite nanoparticles (NPs) have received increasing attention due to their widespread therapeutic and agricultural applicability. In the environmental field, dry powder- and ferrofluid-suspended cobalt ferrite NPs were found to be useful for removing heavy metals and metalloids from water, while diluted suspensions of cobalt ferrite NP have been promisingly applied in medicine. However, the potential toxicological implications of widespread exposure are still unknown. Since cobalt ferrite NPs are considered residual wastes of environmental or...

Toxic and genotoxic effects of graphene and multi-walled carbon nanotubes

Eşref Demir & Ricard Marcos
Graphene and multi-walled carbon nanotubes (MWCNT) are widely used in nanomedicine, and other fields, due to their unique physicochemical properties including high tensile strength, ultra-light weight, thermal and chemical stability, and reliable semi-conductive electronic properties. Although extensive amount of data exist describing their adverse effects including potential genotoxicity, few studies using gene mutation detection approaches in mammalian cells are available, which represents an important gap for risk estimations. The aim of the present study was...

Comparative bioaccumulation and effects of purified and cellular extract of cylindrospermopsin to freshwater fish Hoplias malabaricus

Rodrigo De Cássio Da Silva, Sonia Regina Grötzner, Daniele Dietrich Moura Costa, Juan Ramón Esquivel Garcia, Juan Muelbert, Valéria Freitas De Magalhães, Francisco Filipak Neto & Ciro Alberto De Oliveira Ribeiro
Many tropical freshwater ecosystems are impacted by cyanobacteria blooms increasing the risk of cyanotoxins exposure to aquatic organisms while human populations may be exposed by eating fish, drinking water, or dermal swimming. However, few toxicological data are available on the influence of cyanobacteria blooms in particular, cylindrospermopsin (CYN) on Brazilian neotropical fish. A number of studies demonstrated the ability of CYN to bioaccumulate in freshwater organisms and consequently enter the human food chain. The aim...

Iron–tungsten/titania nanotube films for photoelectrochemical water splitting

M. M. Momeni, Y. Ghayeb & F. Ezati
Iron–tungsten/TiO2 nanotube photoelectrodes have been synthesised by the anodisation process followed by the chemical bath deposition technique in this work. X-ray diffraction analysis, field emission scanning electron microscopy, UV–Vis, energy-dispersive X-ray spectroscopy and photoelectrochemical (PEC) measurements have been used to characterise these photoelectrodes. The ratio of the iron–tungsten deposited on TiO2 nanotubes remarkably influences the PEC performance and the amount of hydrogen. The A1 photoelectrode showed the best PEC activity. The investigation of the recyclability...

Inside out: microbiota dynamics during host-plant adaptation of whiteflies - Supplementay Material

Diego Santos Garcia, Natividad Mestre Rincon, Einat Zchori-Fein & Shai Morin

While most insect herbivores are selective feeders, a small proportion of them feed on a wide range of plants. This polyphagous habit requires overcoming a remarkable array of defenses, which often necessitates an adaptation period. Efforts for understanding the mechanisms involved mostly focus on the insect’s phenotypic plasticity. Here, we hypothesized that the adaptation process might partially rely on transient associations with bacteria. To test this, we followed in a field-like experiment, the adaptation process...

We present a mathematical model formalizing the practice of science in nature. The model, which we name formal science, is constructed within the frameworks of algorithmic information theory and that of theoretic computer science. Formal Science is a significant improvement over the informal practice of science as well as a 'clarification tool par excellence' for the foundation of physics, and as such it is able to derive the corpus of physics as a theorem. Formal...

FRİG VADİSİ ANITLARINDA GÖZLEMLENEN BOZULMA PROBLEMLERİNİN İKLİM İLE İLİŞKİSİ

Musa Tokmak
Frig vadisi üzerinde bir çok kaya anıtı bulunmaktadır. Bu anıtlar zamana karşı direnmektedir. Anıtlar bölgenin coğrafi konumundan dolayı fiziksel bozulmaya daha çok maruz kalmaktadır. Gece ve gündüz sıcaklık farkının yüksek olması, güneş ışıklarına maruz kalınan saat sayısı, bölgede ortalama nem oranı gibi faktörler fiziksel bozulmanın ana faktörleridir. Bunun yanında yağışlı gün sayısı ve atmosferdeki kirli ve zararlı gazlarda fiziksel bozulmaya kimyasal bozulma olarak katkı sağlamaktadır. Frig vadisindeki anıtlar yıllarla karşın verdikleri direnç savaşında maalesef insan...
