Realism, Conservatism, and Tiered Ecological Risk Assessment

چکیده
Recent research has provided valuable momentum for the development and use of population models ecological risk assessment (ERA). In general, ERA proceeds along a tiered strategy, with conservative assumptions deployed at lower tiers that are relaxed higher ever more realistic models. As tier increases, so do levels time effort required by assessor. When faced many stressors, species, habitats, assessors need to find efficiencies. Conservative lower-tier approaches well established, but higher-tier often prioritize accuracy, relatively unexplored tiers. A principle efficiency modeling population-level is articulated evaluated against conceptual model an existing set avian chemical assessment. Here, four published reviewed in increasing order realism (risk quotient → Markov chain nest productivity endogenous lifecycle spatially explicit model). Models compared pairwise fashion according as whether conservatism increases or decreases each step. The shown be challenging ideal, though some cause optimism identified. Strategies suggested studying deployment.

A tiered ecological risk assessment of three chlorophenols in Chinese surface waters.
INTRODUCTION The ecological risks posed by three chlorophenols (CPs), 2,4-dichlorophenol (2,4-DCP), 2,4,6-trichlorophenol (2,4,6-TCP), and pentachlorophenol (PCP) in Chinese surface waters were assessed. MATERIALS AND METHODS This was achieved by applying a tiered ecological risk assessment (ERA) approach ranging from deterministic methods to probabilistic options to measured concentrations o...
متن کاملHuman and Ecological Risk Assessment
Yellow perch (YP) are metal tolerant fish that form large populations in many metal-impacted regions across Canada. While they are able to survive and reproduce successfully in environments with water and sediment metal concentrations that are toxic to many invertebrates, perch experience a suite of direct and indirect impacts. YP were studied in a series of Canadian Precambrian Shield lakes ne...
متن کاملEcological risk assessment of heavy metals from cement factory dust
Background: The release of metals from industrial factories is one of the most important sources of environmental pollution. The present study aimed to determine the concentration of heavy metals like cadmium (Cd), chromium (Cr), manganese (Mn), nickel (Ni), and lead (Pb) in dust around the cement factory. Methods: A total of 22 dust samples were collected from areas around the cement factory...
متن کاملEcological conservatism in the ‘‘living fossil’’ Ginkgo
—The living species Ginkgo biloba is phylogenetically isolated, has a relictual distribution, and is morphologically very similar to Mesozoic and Cenozoic congenerics. To investigate what adaptations may have allowed this lineage to persist with little or no morphological change for over 100 Myr, we analyzed both sedimentological and floral data from 51 latest Cretaceous to middle Miocene Ginkg...
