NUS Environmental Research Institute, National University of Singapore, 1 Create Way, Create Tower #15-02, Singapore 138602, Singapore; Energy and Environmental Sustainability for Megacities (E2S2) Phase II, Campus for Research Excellence and Technological Enterprise (CREATE), 1 CREATE Way, Singapore 138602, Singapore; Department of Chemical and Biomolecular Engineering, National University of Singapore, 4 Engineering Drive 4, Singapore 117585, Singapore. Electronic address:

The aim of this work was to study the effects of plastics (high-density polyethylene (HDPE), polystyrene (PS), polypropylene (PP), and polyethylene terephthalate (PET)) on reactor performance and microbial communities during acidogenic fermentation of food waste for the production of volatile fatty acids (VFA). The addition of HDPE and PS increased total VFA yields by 28% and 47%, respectively, whereas the addition of PP and PET decreased total VFA yields by 6% and 2%, respectively. The highest enhancing performance of PS could be ascribed to its highly porous structure that could provide immobilization effects for microbial growth. Read More

Water Security and Nutrition: Current Knowledge and Research Opportunities.

Adv Nutr 2021 Jul 15. Epub 2021 Jul 15.

Department of Nutrition, University of North Carolina at Chapel Hill, Chapel Hill, NC, USA.

Water is an essential nutrient that has primarily been considered in terms of its physiological necessity. But reliable access to water in sufficient quantities and quality is also critical for many nutrition-related behaviors and activities, including growing and cooking diverse foods. Given growing challenges to water availability and safety, including climate change, pollution, and infrastructure degradation, a broader conceptualization of water and its diverse uses is needed to sustainably achieve global nutrition targets.

Metagenome-Wide Analysis of Rural and Urban Surface Waters and Sediments in Bangladesh Identifies Human Waste as a Driver of Antibiotic Resistance.

mSystems 2021 Jul 13:e0013721. Epub 2021 Jul 13.

Institute of Microbiology and Infection, University of Birmingham, Birmingham, United Kingdom.

In many low- and middle-income countries, antibiotic-resistant bacteria spread in the environment due to inadequate treatment of wastewater and the poorly regulated use of antibiotics in agri- and aquaculture. Here, we characterized the abundance and diversity of antibiotic-resistant bacteria and antibiotic resistance genes in surface waters and sediments in Bangladesh through quantitative culture of extended-spectrum beta-lactamase (ESBL)-producing coliforms and shotgun metagenomics. Samples were collected from highly urbanized settings (7), rural ponds with a history of aquaculture-related antibiotic use (11), and rural ponds with no history of antibiotic use (=6). Read More

The Healthy Crew, Clean Vessel, and Set Departure Date Triad: Successful Control of Outbreaks of COVID-19 On Board Four Cargo Vessels.

Prehosp Disaster Med 2021 Jul 9:1-10. Epub 2021 Jul 9.

Public Health Emergency Operations Centre, Department of Health Western Australia, Perth, Western Australia, Australia.

Background: A variety of infectious diseases can cause outbreaks on board vessels, with both health and economic effects. Internationally, Coronavirus Disease 2019 (COVID-19) outbreaks have occurred on numerous cruise and cargo vessels and the containment measures, travel restrictions, and border closures continue to make it increasingly difficult for ship operators world-wide to be granted pratique, effect crew changes, and conduct trade. An effective outbreak management strategy is essential to achieve the outcome triad - healthy crew, clean vessel, and set departure date - while maintaining the safety of the on-shore workers and broader community and minimizing disruption to trade.

Towards transformative WASH: an integrated case study exploring environmental, sociocultural, economic and institutional risk factors contributing to infant enteric infections in rural tribal India.

BMC Public Health 2021 Jul 6;21(1):1331. Epub 2021 Jul 6.

Population, Policy and Practice, UCL Great Ormond Street Institute of Child Health, London, WC1N 1EH, UK.

Background: Despite clear linkages between poor Water, Sanitation, Hygiene (WASH) and enteric disease, the design of effective WASH interventions that reduce child enteric infections and stunting rates has proved challenging. WASH factors as currently defined do not capture the overall exposure factors to faecal pathogens through the numerous infection transmission pathways. Understanding the multiple and multifaceted factors contributing to enteric infections and their interconnectedness is key to inform future interventions. Read More

Lancet 2021 Jul;398 Suppl 1:S49

Remedial Education Center, Gaza Strip, occupied Palestinian territory.

Background: Public health research suggests that multiple factors contribute to the mental health sequalae of political violence, but the daily experiences and ongoing strategies of psychological survival during active warfare are not clearly understood. We analysed retrospective chronological diaries from Palestinian women in Gaza, occupied Palestinian territory, to explore their lives during Operation Protective Edge in 2014, when a series of aerial bombardments killed over 2000 Palestinians and left around 500 000 displaced from their homes.

Methods: 20 Palestinian female teachers in Gaza were recruited via an intervention for trauma recovery 1 month after the end of Operation Protective Edge, in September, 2014. Read More

Electronic address:

Anthropogenic structures are increasingly encroaching wildlife habitats, creating conflicts between humans and animals. Scaling up renewable energy requires new infrastructures such as power lines, that cause high mortality among birds since they act as obstacles to flight and are used for perching and nesting, which can result in collisions or electrocutions. These interactions often endanger wildlife populations and may also result in high financial costs for companies. Read More

[Different Responses of Soil Dissolved Organic Matter to Different Types of Compost].

Huan Jing Ke Xue 2021 Jul;42(7):3565-3576

State Key Laboratory of Environment Criteria and Risk Assessment, Chinese Research Academy of Environmental Sciences, Beijing 100012, China.

This study explored the responses of soil dissolved organic matter (DOM) to the application of different types of compost using a soil sample without compost as a control. Ultraviolet and fluorescence spectrum technology and EEM-PARAFAC was used to analyze DOM structure and driving factors in soil added with different proportion of cow dung compost (SCC), food and kitchen waste compost (SFC), and sludge compost (SCC). Compared with the control group, contents of AN, NH-N, DOC, and SOM in soil added with compost were significantly increased, and contents of SOM and DOC increased with the increasing of compost amount.
