There’s been a lot of work done on stressor interactions – about four or five studies (from freshwater systems alone) are currently being published every week. These experiments have studied the effects of over 900 stressors (>80% of these being different chemicals).

The relative interest in different stressors has fluctuated over time and some combinations of stressors are far more likely to be studied than others. Temperature has become more popular in the past decade and has been paired with virtually all other types of stressors.
