NH, NO, NO and NO losses, emission factors and reduction mechanisms under different N managements from greenhouse vegetable soils.

Excessive nitrogen (N) application in greenhouse cultivation has led to substantial reactive N (Nr) emissions from soils, necessitating effective mitigation strategies. This study presents simultaneous high-frequency monitoring of ammonia (NH) volatilization, nitrous oxide (NO), nitric oxide (NO) and nitrogen dioxide (NO) emissions across three greenhouse vegetable seasons (tomato, cabbage and lettuce) under different N management regimes. Key findings reveal that emission factors of NH, NO, NO, and NO were 0.

Persistent organic pollutants exposure and risk of depression: A systematic review and meta-analysis.

Recently, more and more epidemiological studies have examined the impact of exposure to persistent organic pollutants (POPs) on depression, but the results are inconsistent. Thus, we conducted a systematic review and meta-analysis to better understand the effects of POPs exposure on the risk of depression in the general population. We searched PubMed, Embase, Web of Science, and Scopus databases for studies before March 20, 2024.

Combined effects of bacteria and antibiotics on surface properties and transport of nanoplastics in porous media.

Currently, research on the individual effects of bacteria and antibiotics on the transport of nanoplastics (NPs) in porous media is in its infancy, while research on their combined effect is absent. It is well known that bacteria and antibiotics also interact with each other, so this synergistic transport of bacteria, antibiotics, and NPs in porous media must be very interesting. For exploring this aspect, we investigated the individual and combined effects of bacteria and antibiotics on the transport of polystyrene NPs (PS-NPs) in saturated porous media.

Transport of polystyrene nanoplastics in porous media: Combined effects of two co-existing substances.

Both surfactants and natural organic matters (NOMs) are substances commonly found in aqueous environments, and their effects on the transport of nanoplastics that is gradually gaining widespread attention in porous media are currently in their infancy, while their combined effects are absent. We investigated innovatively the combined effect of surfactants and NOMs on the transport of polystyrene nanoplastics (PS-NPs) in saturated porous media. Adsorption tests of surfactants and NOMs onto PS-NPs, adsorption tests of PS-NPs onto quartz sand, and transport tests of PS-NPs in saturated quartz sand were conducted.

Cost-effective integrated conservation and restoration priorities by trading off multiple ecosystem services.

Conservation and restoration have long been regarded as two separate management avenues to maintain or enhance ecosystem functioning. Despite the commonalities in goals, restoration is generally considered a lower priority than conservation due to its generally greater cost, uncertainties in multiple trajectories and deals with already degraded habitats. However, when resources and opportunities for meeting conservation needs are limited, restoration could be an imperative avenue to provide additional benefits from conservation.

Formulating win-win management plans in Protected Areas (PAs) based on Key Ecosystem services (KESs): An application in the Shennongjia National Park, China.

Exploring win-win approaches to ecological conservation and community development goals is a central issue in the management of PAs. Achieving sustainable management of ESs in PAs is more of a social governance issue, requiring the SES managers to understand the diverse tradeoffs among ESs and well-beings and design management plans with supportive governance processes and institutions. To solve this issue, ESs importance was chosen as the entry point, which is good at "understanding" but weak in "designing" in most cases.

Synergic Benefits of Air Pollutant Reduction, CO Emission Abatement, and Water Saving under the Goal of Achieving Carbon Emission Peak: The Case of Tangshan City, China.

The study aims to explore the synergic benefits of reducing air pollutants and CO and water consumption under the carbon emission peak (CEP) policies at a city level. Air pollutants and CO emissions are predicted by the Low Emissions Analysis Platform (LEAP) model, and the water consumption is forecast by the quota method. Two scenarios are constructed with the same policies, but to different degrees: the reference scenario achieves CEP in 2030, and the green and low carbon scenario achieves CEP in 2025.
