Effects of Glyphosate on the Planktonic Microbiota: An Experimental Approach

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Glyphosate is one of the most widely used herbicides in the world, including in Brazil, and its dispersion through habitats and surface waters can impact entire aquatic ecosystems. However, experimental studies evaluating the effects of pesticides on whole planktonic communities, considering attributes such as richness, density and composition—

First Assessment of Genetic Damage in the Speckled Cockroach (Nauphoeta cinerea) After Consumption of Lettuce (Lactuca sativa) Cultivated and Commercialized in Northeastern, Brazil

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT This study reports, for the first time, the use of the speckled cockroach Nauphoeta cinerea as a promising bioindicator for genotoxic monitoring. It was validated through control groups (both positive and negative) in addition to testing lettuce (Lactuca sativa ) samples from public street markets consumed by N. cinerea specimens in Pernambuco,

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

South Asian monsoon history over the past 60 kyr recorded by radiogenic isotopes and clay mineral assemblages in the Andaman Sea [PDF]

open access: yes, 2015
The Late Quaternary variability of the South Asian (or Indian) monsoon has been linked with glacial‐interglacial and millennial scale climatic changes but past rainfall intensity in the river catchments draining into the Andaman Sea remains poorly ...
