A comparative study of deep learning-based network model and conventional method to assess beach debris standing-stock.

Mar Pollut Bull 2021 May 11;168:112466. Epub 2021 May 11.

A.I. Platform Department, HancomInSpace Co., Ltd, Daejeon 34103, Republic of Korea.

The conventional survey of marine debris standing-stock has various drawbacks such as high cost and inaccuracy because the total amount of debris in the whole beach is inferred using the results of the manual investigation in selected narrow areas. To overcome the disadvantages, an automatic detection method using a deep learning-based network model was developed to detect and quantify the beach debris. The network model developed in this study classified items with a precision of 0. Read More

Distribution and Emission Estimation of Short- and Medium-Chain Chlorinated Paraffins in Chinese Products through Detection-Based Mass Balancing.

Environ Sci Technol 2021 May 14. Epub 2021 May 14.

State Key Joint Laboratory for Environmental Simulation and Pollution Control, College of Environmental Sciences and Engineering, Peking University, Beijing 100871, China.

Short- and medium-chain chlorinated paraffins (SCCPs and MCCPs, respectively) have raised environmental concern due to their potential for persistence, long-range transport, bioaccumulation, and toxicity. However, little is known about the production, use, and environmental emissions of SCCPs and MCCPs in China, the world's largest producer and consumer. In this study, we estimated the amounts of SCCPs and MCCPs produced and used in China in 2018-2019 based on a nationwide survey and measurements of concentrations in products, from which we estimated the environmental emissions of SCCPs and MCCPs in China.

A conflicts' classification for IoT-based services: a comparative survey.

PeerJ Comput Sci 2021 27;7:e480. Epub 2021 Apr 27.

Computer Science Department, Faculty of Computers and Artificial Intelligence, Cairo University, Giza, Egypt.

Recently, Internet of Things (IoT)-based systems, especially automation systems, have become an indispensable part of modern-day lives to support the controlling of the networked devices and providing context-aware and intelligent environments. IoT-based services/apps developed by the end-users interact with each other and share concurrent access to devices according to their preferences, which increases safety, security, and correctness issues in IoT systems. Due to the critical impacts resulting from these issues, IoT-based apps require a customized type of compilers or checking tools that capable of analyzing the structures of these apps and detecting different types of errors and conflicts either in intra-IoT app instructions or in inter-IoT apps interactions.

Biomarkers of poly- and perfluoroalkyl substances (PFAS) in Sub-Arctic and Arctic communities in Canada.

Int J Hyg Environ Health 2021 May 10;235:113754. Epub 2021 May 10.

School of Public Health and Health Systems, Faculty of Applied Health Sciences, University of Waterloo, 200 University Avenue West, Waterloo, Ontario, N2L 3G1, Canada. Electronic address:

Polyfluoroalkyl substances and perfluoroalkyl substances (PFAS) are a family of anthropogenic chemicals that are used in food packaging, waterproof clothing, and firefighting foams for their water and oil resistant properties. Though levels of some PFAS appear to be decreasing in Canada's south, environmental levels have been increasing in the Arctic due to long-range transport. However, the implications of this on human exposures in sub-Arctic and Arctic populations in Canada have yet to be established. Read More

Domoic acid and saxitoxin in seabirds in the United States between 2007 and 2018.

Harmful Algae 2021 Mar 1;103:101981. Epub 2021 Apr 1.

Environmental and Fisheries Science Division, Northwest Fisheries Science Center, National Marine Fisheries Service, National Oceanographic and Atmospheric Administration, 2725 Montlake Blvd. East, Seattle, WA 98112 United States. Electronic address:

As harmful algal blooms (HABs) increase in magnitude and duration worldwide, they are becoming an expanding threat to marine wildlife. Over the past decade, blooms of algae that produce the neurotoxins domoic acid (DA) and saxitoxin (STX) and documented concurrent seabird mortality events have increased bicoastally in the United States. We conducted a retrospective analysis of HAB related mortality events in California, Washington, and Rhode Island between 2007 and 2018 involving 12 species of seabirds, to document the levels, ranges, and patterns of DA and STX in eight sample types (kidney, liver, stomach, intestinal, cloacal, cecal contents, bile, blood) collected from birds during these events.

[Establishing an integrated hospital-community pyramid for screening and achieving hepatocellular carcinoma early diagnosis and treatment].

Zhonghua Gan Zang Bing Za Zhi 2021 Apr;29(4):289-292

Department of Infectious Diseases, Nanfang Hospital, Southern Medical University, State Key Laboratory of Organ Failure Research, Guangdong Provincial Key Laboratory of Viral Hepatitis Research, Guangzhou 510515, China Shenzhen Hospital, Southern Medical University, Shenzhen 518110, China.

The comprehensive management of hepatocellular carcinoma (HCC) is a complete, dynamic and personalized process. Therefore, how to scientifically determine the HCC high-risk/extremely high-risk populations and develop a stratified monitoring plan is the key link to early detection, diagnosis and improvement of overall survival. In addition, accurately identifying high-risk/extremely high-risk groups based on the HCC risk prediction model, and applying it to establish an integrated hospital-community pyramid for HCC screening through the implementation of interdisciplinary scientific management and treatment may ultimately reduce HCC-related mortality rate.

Cross-ecosystem fluxes of pesticides from prairie wetlands mediated by aquatic insect emergence: implications for terrestrial insectivores.

Environ Toxicol Chem 2021 May 12. Epub 2021 May 12.

Fort Collins, CO, 80526, USA.

Contaminants alter the quantity and quality of insect prey available to terrestrial insectivores. In agricultural regions, the quantity of aquatic insects emerging from freshwaters can be impacted by insecticides originating from surrounding croplands. We hypothesized that, in such regions, adult aquatic insects could also act as important vectors of pesticide transfer to terrestrial food webs. Read More

Optimising the cost of roadkill surveys based on an analysis of carcass persistence.

J Environ Manage 2021 May 8;291:112664. Epub 2021 May 8.

Wildlife and Reserve Management Research Group, Department of Zoology and Entomology, Rhodes University, Grahamstown, 6140, South Africa; School of Biology and Environmental Sciences, University of Mpumalanga, Nelspruit, 1200, South Africa.

Reliable estimates of wildlife mortality due to wildlife-vehicle collisions are key to understanding its impact on wildlife populations and developing strategies to prevent or reduce collisions. Standardised approaches for monitoring roadkill are needed to derive robust and unbiased estimates of mortality that are comparable across different study systems and ecological contexts. When designing surveys, there is a trade-off between survey frequency (and hence logistical effort and financial cost) and carcass detection. Read More

Characterisation of Brucella species and biovars in South Africa between 2008 and 2018 using laboratory diagnostic data.

Vet Med Sci 2021 May 11. Epub 2021 May 11.

Biometry Division, Agriculture Research Council, Stellenbosch, South Africa.

Background: Brucellosis is an infectious zoonotic bacterial disease of humans and other animals. In the Republic of South Africa (RSA), animal brucellosis is widespread and the current available data on the prevalence of this disease rely solely on serological testing. The primary limitation of brucellosis serology is the lack of discriminatory powers to differentiate between Brucella species and biovars as well as the cross-reactivity observed with other Gram-negative bacteria.
