For decades, such work relied mainly on indirect methods, testing water, air and food for contamination; assuming that environmental levels correspond to levels in the body, and then using either animal tests or statistical analysis to disclose threats.
A slight decrease appeared during the exposure at contamination level similar to the environmental levels.
Table 2 gives examples of theory-based methods at the individual and environmental levels.

Nowadays the European cities usually present important problems at economic, social and environmental levels.
After exposure, all species had plasma nitrite-N concentrations greater than environmental levels.
With respect to environmental levels, methods are linked to each level: interpersonal, organizational, community and policy levels.

Combined effects of TBT and BaP exposure at environmental levels on these biomarkers should be further researched.
Plasma gasification consistently exhibits much lower environmental levels for both air emissions and slag leachate toxicity than other thermal technologies.
The optimized method was applied to different sludge samples to determine the environmental levels of anticancer drugs.
