Ecological bases of Ecotoxicology<br />
• The basis for determining the effects of<br />
<strong>contaminants</strong> on ecosystem is at<br />
organism level<br />
• At organism level, response can be:<br />
– Acute toxicity causing mortality<br />
– Chronically accumulating damage ultimately<br />
causing death<br />
– Sublethal impairment of various aspects of<br />
physiology <strong>and</strong> morphology<br />
– Sublethal behavioral effects<br />
– Measurable biochemical changes
