Environmental has been postulated to be aerosolized during ploughing and heavy rain, and could result in inhalational melioidosis. Here, we determined the presence of in soil, paddy field water (PFW), air, and rainwater samples in a single rice paddy field in Ubon Ratchathani, northeast Thailand. In 2012, we collected 100 soil samples during the dry season, 10 PFW samples during the monsoon season, 77 air samples during ploughing ( = 31) and heavy rains ( = 46), and 60 rainwater samples during 12 rain events. We found that 32 soil samples (32%), six PFW samples (60%), and none of the air and rainwater samples were culture positive for . Other soil bacteria were isolated from air and rainwater samples. Mean quantitative count of estimated from two culture-positive PFW samples was 200 colony forming units/mL. Our findings suggest that the risk of melioidosis acquisition by inhalation in Thailand might be low.

Soil samples collected from an aqueous film-forming foam (AFFF)-impacted sandy soil formation at two depth intervals above the water table were used in bench-scale column experiments to evaluate the release of poly- and perfluoroalkyl substances (PFASs) under different degrees of water saturation. Artificial rainwater was applied to the soils under constant and variably saturated conditions. Results from constant saturation experiments suggest that retention of PFAS mass at air-water interfaces was evident in the deep soil (f < 0.

The study assessed the sensitivity of 20 provenances of European larch (Larix decidua Mill.) growing at provenance experimental trials located in lowland (Siemianice) and upland (Bliżyn) climate in Central Poland to air temperature and precipitation, including drought. The measure of the tree' sensitivity was their radial growth reactions, i.

Article Synopsis
- The study examines how rainwater affects the oxidation and spontaneous combustion of high-sulfur coal gangue from Inner Mongolia, particularly under varying moisture conditions.
- * When coal gangue samples were treated with different moisture levels, the optimal conditions for low-temperature oxidation were found at 25% moisture, yielding the highest concentrations of gases at 390 °C.
- * However, moisture levels above 70% diluted combustible materials, reducing gas concentrations below control levels and making spontaneous combustion less likely, while also lowering generation temperatures for gases.
Environmental Occurrence and Biotic Concentrations of Ultrashort-Chain Perfluoroalkyl Acids: Overlooked Global Organofluorine Contaminants.

Article Synopsis
- PFASs are a group of man-made chemicals, and ultrashort-chain PFAAs have become a focus due to their environmental impact and prevalence.
- A literature database from 1990 to 2024 reveals that these ultrashort-chain PFAAs, particularly TFA, are widely found in various environments and often at higher concentrations than longer-chain PFASs.
- The review also indicates that ultrashort-chain PFAAs are present in many living organisms, including humans, and emphasizes the need for research and regulation due to their increasing significance in environmental health discussions.
