Use a specific toxin name or CAS number to search. See Home tab for more information about CAS numbers.
Consider using non-technical names for toxins because news articles are more likely to use terms the general public can understand. For example, rather than searching petroleum hydrocarbons, search oil spill.
Consider adding a specific geographic location or any of these terms: toxicity, pollution, biodegradation, remediation, or bioremediation.
