Article Abstract
To clarify the environmental capacity of heavy metals in sediments of Chengxi Lake and Chengdong Lake in Huoqiu County, 30 sediment samples were collected from Chengxi Lake and Chengdong Lake, respectively. The environmental capacity characteristics and spatial distribution of heavy metals in sediments of Chengxi Lake and Chengdong Lake were studied using the comprehensive environmental capacity index, the static and dynamic environmental capacity was estimated, and the change trend of nearly one hundred years was predicted. The results showed that the average contents of As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn in the sediments of Chengxi Lake and Chengdong Lake did not exceed the national soil risk screening values. The average values of the single environmental capacity index of heavy metals in the sediments of Chengxi Lake and Chengdong Lake were in the following orders:Ni(0.81)

To identify potential sources of hookworm infections in a Ghanaian community of endemicity that could be targeted to interrupt transmission, we tracked the movements of infected and noninfected persons to their most frequented locations. Fifty-nine participants (29 hookworm positives and 30 negatives) wore GPS trackers for 10 consecutive days. Their movement data were captured in real time and overlaid on a community grid map.

Background: Although existing disease preparedness and response frameworks provide guidance about strengthening emergency response capacity, little attention is paid to health service continuity during emergency responses. During the 2014 Ebola outbreak, there were 11,325 reported deaths due to the Ebola virus and yet disruption in access to care caused more than 10,000 additional deaths due to measles, HIV/AIDS, tuberculosis, and malaria. Low- and middle-income countries account for the largest disease burden due to HIV, tuberculosis, and malaria and yet previous responses to health emergencies showed that HIV, tuberculosis, and malaria service delivery can be significantly disrupted.

The exploration of extraterrestrial environments has become a focal point of scientific inquiry, driven by advancements in technology and a growing interest in the potential for life beyond Earth. This study investigates the adaptability of Antarctic nematodes, known for thriving in extreme cold and isolation, to simulated Martian (MGS-1) and Lunar (LMS-1) soils. The experiment revealed differential responses in nematode survivability to the two simulants, with Lunar soil demonstrating better adaptability compared to Martian soil.

Aging inevitably gives rise to many challenges and transitions that can greatly impact our (mental) well-being and quality of life if these are not controlled adequately. Hence, the key to successful aging may not be the absence of these stressors, but the ability to demonstrate resilience against them. The current study set out to explore how resilience and successful aging may intersect by investigating how various resilience capacity-promoting (protective) and resilience capacity-reducing (risk) factors relate to mental well-being and quality of life.

Photochemical weathering and eco-corona formation through natural organic matter (NOM) adsorption play vital roles in the aggregation tendencies of nanoplastics (NPs) in aquatic environments. However, it remains unclear how photochemical weathering alters the adsorption patterns of NOM and the conformation of the eco-corona, subsequently affecting the aggregation tendencies of NPs. This study examined the effect of Suwannee River NOM adsorption on the aggregation kinetics of pristine and photoaged polystyrene (PS) NPs in monovalent electrolyte solutions.
