Antibiotics in two municipal sewage treatment plants in Sri Lanka: Occurrence, consumption and removal efficiency

Emerging Contaminants, 2019
Most of the monitoring data on the occurrence of antibiotics in sewage treatment plants (STPs) have been reported from Europe, North America and some countries in Northeast Asia, while very limited data can be found in Southeast Asian countries.

Coastline Fractal Dimension of Mainland, Island, and Estuaries Using Multi-temporal Landsat Remote Sensing Data from 1978 to 2018: A Case Study of the Pearl River Estuary Area

Remote Sensing, 2020
The Pearl River Estuary Area was selected for this study. For the past 40 years, it has been one of the most complex coasts in China, yet few studies have analyzed the complexity and variations of the area’s different coastlines.

Honey-collecting in prehistoric West Africa from 3500 years ago

Nature Communications, 2021
Though there is a long archaeological record of the use of honey, beeswax and other bee products, there are few known records from Africa. Here Dunne et al.

Compositional Characteristics of Fluvial Particulate Organic Matter Exported From the World's Largest Alpine Wetland [PDF]

, 2019
Wetlands are hot spots for particulate organic matter (POM) supply into rivers, which link the land-ocean transfer in the global carbon cycle. However, the source, composition, and seasonal variability of POM carried by wetland-draining rivers are poorly

The impact of forced closure on proppant distribution of hydraulic fracturing in shale formations

Deep Underground Science and Engineering, EarlyView.
Research findings demonstrate that implementing forced closure within shale formations can remarkably mitigate proppant settlement, concurrently increasing the effective propped surface area from 29.74% to 38.68%. Abstract Forced closure is widely used in conventional oil and gas reservoirs to promote uniform proppant placement.

Ozone Formation at a Suburban Site in the Pearl River Delta Region, China: Role of Biogenic Volatile Organic Compounds

Atmosphere, 2023
Ozone (O3) is becoming an increasingly concerning air quality problem in China, and previous O3 control strategies focused primarily on reducing anthropogenic volatile organic compounds (AVOCs), while neglecting the role of biogenic VOCs (BVOCs) in O3 ...

Organic Geochemistry

, 2019
The Pacific Island ecosystems of Remote Oceania were dramatically transformed following the arrival of humans within the last ∼3000 years, as the new settlers required technological innovations and environmental modifications to maintain their populations. These modifications included the introduction of numerous exotic species, including the important

Dark carbon fixation in the Arabian Sea oxygen minimum zone contributes to sedimentary organic carbon (SOM) [PDF]

, 2019
In response to rising CO2concentrations and increasing global sea surface temperatures,oxygen minimum zones (OMZ), or“dead zones”, are expected to expand.

High atmospheric pressure rescues plant growth under humidity stress: A model for climate‐resilient deep underground agriculture

Deep Underground Science and Engineering, EarlyView.
High atmospheric pressure (120 kPa) in deep underground counteracts humidity‐induced physiological stress in plants, stabilizing water balance and enhancing antioxidative defenses. This synergy boosts biomass despite elevated humidity, demonstrating sustainable deep underground agriculture potential under climate uncertainty.
