Behavioural ecotoxicology, an “early warning” signal to assess environmental quality

Behavioural ecotoxicology, an “early warning” signal to assess environmental quality

BACKGROUND In this review, the position of behavioural ecotoxicology within the available means to assess the status of marine environments is described as filling the gap for the needed "early warning" signals. A few examples of studies performed since the 1960s are discussed to highlight the sensitivity of these approaches in investigating the effects of chemicals, including priority pollutan...

An early warning on early warning systems!

An Early Warning System for Vehicle Related Quality Data

Vehicle production audit tests, warranty claims and car control unit data are stored in a central data warehouse for data mining analysis. Neural network based part failure rate estimations, adjusted for mileage and seasonality, are used for monitoring warranty claims. Association and sequence analysis connect production audit data, car control unit data and warranty claims for an early detecti...

Micronucleus assay- an early diagnostic tool to assess genotoxic changes in tobacco and related habits

Objective: Micronuclei are induced in cells by a variety of substances, like UV radiation, infrared rays, X-radiations, and chemicals. Among them tobacco- specific nitrosamines have been reported to be potent mutagenic agents which are thought to be responsible for the induction of chromosomal aberrations resulting in production of micronuclei. The main aim of our study is to compare MN frequen...

Behavioural Adaptation to Fatigue Warning Systems

Driver impairment due to fatigue induced drowsiness is a significant cause of vehicle collisions. One countermeasure that is currently being implemented is Fatigue Warning Systems (FWS) to alert drivers that are drowsy. Behavioural adaptation of drivers to a FWS was evaluated in a closed track study. Thirty-two drivers completed two lengthy overnight drives, separated by one week, with half the...
