Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Integrated Species Distribution Model Using Historical Data Shows Decline in a Common Semi‐Aquatic Mammal

Animal Conservation, EarlyView.
A diagram of the integrated species distribution model of river otter intensity of use. Three types of data (latrine detections, roadkill detections, and detection/nondetection surveys) are linked by different observation processes to the same underlying intensity of use.

Microplastic Impacts on Seafood: A Global Synthesis of Experimental Findings

Fish and Fisheries, EarlyView.
ABSTRACT Plastic pollution is a growing global concern, with plastic and microplastic particles now widespread in aquatic environments. Microplastics are frequently ingested by marine organisms, including commercially important seafood species. Ingestion can lead to a range of biological effects, influenced by the size, type and quantity of plastic, as

Occurrence of multiple congenital anomalies in Potamotrygon amandae (Elasmobranchii, Potamotrygoninae) embryos, including the first report of bicephaly

Journal of Fish Biology, EarlyView.
Abstract Reports of teratogenic embryos in elasmobranchs have been documented in multiple species, with proposed aetiologies including environmental disturbances, genetic mutations, predation, exposure to endocrine‐disrupting compounds and maternal stress.

Polychlorinated biphenyls, glycaemia and diabetes in a population living in a highly polychlorinated biphenyls-polluted area in northern Italy: a cross-sectional and cohort study

Journal of Public Health Research, 2013
Background. Polychlorinated biphenyls (PCBs) have been found to be associated with diabetes in some, but not all, studies performed so far. The aim of this study was to assess the association between PCB serum levels and glycaemia and diabetes in people ...
