(a) Static representation of the environment

(b) Chemical discharge

(c) Simplified dynamic approach

(d) Site history

This question was posed to me in semester exam.

Answer 1

Right option is (d) Site history

Best explanation: Evaluating organism exposure in ecosystems is a difficult and can be carried out measuring or predicting concentrations in the environment. Current regulatory approaches favour modelling approach, they either use a static representation of the environment and of the chemical discharge or a simplified dynamic approach.
