Mechanistic effect models for ecological risk assessment of chemicals (MEMoRisk) — A new SETAC-Europe Advisory Group [PDF]

, 2009
Recent reviews of the state-of-the-art of ecological modeling for risk assessments have highlighted the need for standardization of modeling approaches (Pastorok et al. 2003; Grimm et al. 2009).

A Procedure for Ecological Tiered Assessment of Risks (PETAR)

, 2004
Several procedures for Ecological Risk Assessment (ERA) have been suggested. The use of these existing procedures often relies on availability of existing data and/or on large resources for acquisition of new ones.

Simultaneous Degradation, Dehalogenation, and Detoxification of Halogenated Antibiotics by Carbon Dioxide Radical Anions

Engineering
Despite the extensive application of advanced oxidation processes (AOPs) in water treatment, the efficiency of AOPs in eliminating various emerging contaminants such as halogenated antibiotics is constrained by a number of factors.

Establishing an ecological security pattern for urban agglomeration, taking ecosystem services and human interference factors into consideration [PDF]

PeerJ, 2019
The assessment of ecological security patterns is a topic of conversation in landscape ecology in recent years. However, ecosystem services and human activities are seldom considered comprehensively in the assessment of ecological security patterns.

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite

Advanced Functional Materials, EarlyView.
The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

Photo‐Switchable Molecular Module Programming PET Biodegradation in Aquatic Environments

Advanced Functional Materials, EarlyView.
We address the plastic durability paradox by integrating an itaconic acid–derived pyrrolidone module into polymer backbones. Sunlight in water triggers Norrish Type I ring‐opening and hydrophilization, enabling rapid biodegradation into nontoxic minerals.

Ecological Risk Assessment and Ecological Security Pattern Optimization in Binzhou City

Chemical Engineering Transactions, 2018
In this research, we created an assessment model based on ecological footprint and ecological carrying capacity (EC) to detect the trend of urbanization in Binzhou city. In this model, we utilized four new indicators based on EF and EC by adding economic

An Adjusted Landscape Ecological Security of Cultivated Land Evaluation Method Based on the Interaction between Cultivated Land and Surrounding Land Types

Land, 2023
Because the relationship between cultivated land and the surrounding land types is not taken into account, there existed a deviation in the assessment of cultivated landscape ecological security.
