Impact of oil-related environmental pollutants on the ovary structure in the freshwater leech Erpobdella johanssoni (Johansson, 1927) (Clitellata: Hirudinea)

The European Zoological Journal, 2017
Toxicity of organic chemical compounds, including benzene, toluene, ethyl benzene and xylene (BTEX), is a major concern because of their induction of adverse effects in organisms, including reproductive abnormalities.

Volatile Organic Compounds in Rainwater: A New Frontier in Atmosphere–Biosphere Interactions

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.
Abstract Rainwater is a key vector of atmospheric deposition, linking the atmosphere with terrestrial and aquatic ecosystems. While the inorganic chemistry of precipitation (dominated by sulfate, nitrate, ammonium, and trace metals) has been extensively studied, organic compounds in rainwater have received less attention, and Volatile Organic Compounds

A Simple Parallel Screening Method for Gas–Solid Photodegradation Catalysis

Chemistry–Methods, Volume 6, Issue 8, August 2026.
This work describes a facile option for preliminary‐stage testing of various heterogenous photocatalytic materials or conditions, using a conventional hot dog cooker to provide uniform heating and rotation of sealed vials irradiated from above. Varying conditions can be tested in parallel, and we find this method particularly useful for gas‐solid ...

Observations and numerical simulations of a valley‐exit wind in the Alpine Bolzano basin

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 779, July 2026 Part B.
The evolution and spreading of the nocturnal valley‐exit wind flowing from the Isarco Valley into the Bolzano basin, in the Italian Alps, are found to be influenced by the basin temperature stratification. Measurements and high‐resolution simulations show that a cold‐air pool favors an upward trajectory of the flow at the exit of the valley.

From Citrus to Cymene: Understanding the Hydrothermal Conversion of Limonene

ChemSusChem, Volume 19, Issue 11, 15 June 2026.
When life gives you limonene… Hydrothermal conversion and pyrolysis of limonene give two distinct sets of products, arising from differing reaction cascades. While p‐cymene dominates in the presence of water, indicative of an isomerisation/aromatisation pathway, pyrolysis favours cracking and loss of carbon affording an m‐xylene rich aromatic mix.
