The biological context for the selection of the herring gull (Larus argentatus), from a long list of candidate species, as an indicator of the restoration of Great Lakes water quality is further elaborated. Embryo mortality and deformities in herring gull chicks led to the hypothesis that the Lake Ontario population was exhibiting chick edema disease. Subsequent observation of the suite of lesions associated with chick edema disease in herring gull chicks led to the hypothesis that the Great Lakes were contaminated with polychlorinated dibenzo-p-dioxins. Forensic toxicology, as a collaboration of environmental chemistry, biology and pathology, could form a rational basis for policy decisions about remedial actions to restore extirpated fish and wildlife populations and to protect public health. Key words: indicator, restoration, diagnosis, forensic toxicology, public health.

Abstract The specific features of the measuring instruments verification based on the results of their calibration are considered. It is noted that, in contrast to the verification procedure used in the legal metrology, the verification procedure for calibrated measuring instruments has to take into account the uncertainty of measurements into account. In this regard, a large number of measuring instruments, considered as those that are in compliance after verification in the legal metrology, turns out to be not in compliance after calibration. In this case, it is necessary to evaluate the probability of compliance of indicating measuring instruments. The procedure of compliance probability determination on the basis of the Monte Carlo method is considered. An example of calibration of a Vernier caliper is given.

AbstractThe microplastic cycle was originally and formally introduced and defined as a novel concept and paradigm for understanding plastic pollution and its fluxes across ecosystem reservoirs. This concept has now been expanded to include macroplastic particles and links all aspects of the fate, transport, and effects of plastic pollution, including source-receptor models in the environment, and expanded on previously established perspectives that viewed the plastic pollution issue in a less integrated manner. The value of this paradigm is that this perspective integrates three basic scientific spheres: environmental chemistry, biology (i.e., trophic transfer), and human health. The goal of this chapter is to introduce readers to the microplastic pollution problem and to outline the microplastic cycle as a concept and holistic paradigm for addressing this ubiquitous environmental and potential public health problem. The specific objectives of this chapter were to (1) introduce this volume and its chapters by outlining the microplastic pollution issue in the context of the entire plastic cycle; (2) evaluate fluxes of microplastics across different ecosystem compartments, including the atmosphere, lithosphere, hydrosphere. and biosphere, including humans; and (3) provide insights on public policy and potential solutions to the microplastic pollution problem.
