Studies of unexplained symptoms observed in chemically sensitive subjects have increased the awareness of the relationship between neurological and immunological diseases due to exposure to volatile organic compounds (VOCs). However, there is no direct evidence that links exposure to low doses of VOCs and neurological and immunological dysfunction. We review animal model data to clarify the role of VOCs in neuroimmune interactions and discuss our recent studies that show a relationship between chronic exposure of C3H mice to low levels of formaldehyde and the induction of neural and immune dysfunction. We also consider the possible mechanisms by which VOC exposure can induce the symptoms presenting in patients with a multiple chemical sensitivity.

Transmission of Zika virus (ZIKV) has been reported in 92 countries and the geographical spread of invasive virus-borne vectors has increased in recent years. Arboviruses naturally survive between vertebrate hosts and arthropod vectors. Transmission success requires the mosquito to feed on viraemic hosts.

The Metropolitan Area of São Paulo (MASP) in southern Brazil is impacted by high ozone levels posing significant threats to its urban forests and the Atlantic Forest remnants. These green areas, covering 540 km and constituting 30% of MASP's territory, necessitate an urgent assessment of air pollution impacts on their flora. Our study investigates the effects of atmospheric pollution on the morphoanatomical and physiological responses of four native tree species (Alchornea sidifolia, Casearia sylvestris, Guarea macrophylla, and Machaerium nyctitans) across two Atlantic Forest remnants in MASP.

The extraction of plant essential oils (EOs) and analysis by gas chromatography coupled to mass spectrometry (GC-MS) are standard methods when studying aromatic plants and the chemical composition of EOs. Here, two simple methods for the extraction of EO compounds from leaves of Thymus vulgaris are described. Organic solvent extraction and solid-phase microextraction (SPME), respectively, are used and the results of the GC-MS analyses are compared.

Emissions of ethyl acetate (EA) exhaust from industrial sources can cause environmental and health risks. EA can be effectively removed by biological filtration with low operating costs and promising good benefits. This study demonstrated the synergistic effect of using magnetite and pebbles as bio-packing in promoting microbial activity and microbial abundance for EA degradation.

Despite benzotriazole UV stabilizers (BT-UVs) being widely used since the 1960s, few empirical data on their atmospheric presence exist. UV-328 was added to the Stockholm Convention on Persistent Organic Pollutants, based in part on model calculations indicating atmospheric long-range transport potential. We investigated the atmospheric occurrence of BT-UVs at multiple sites that differ greatly in their proximity to potential sources.
