Should other research confirm the effects (whether positive or negative) of air pollutants on gestational age, it is possible that the effects observed for particular pollutants may be indicators of the urban air pollution mix.
Our method of estimating individual exposure to outdoor air pollutants may be more accurate because it takes account many influences on air pollution levels.
Secondly, the particles possess a large surface area, and pollutants may be sorbed to these surfaces5.
Many islanders are already believers, and they worry that the pollutants may be threatening their health.
Air pollutants may be regulated by federal and state laws or by nuisance complaints.
Hazardous air pollutants may be released when equipment leaks or when material is transferred, or they may be emitted from smokestacks.
It is suspected that limit values for traffic-related pollutants may be exceeded near busy streets, although respected at urban background sites.
Nuclear power plants, however, do yield waste heat that may be considered thermal pollution, and they also yield useless and dangerous radioactive wastes that, although they are pollutants, may be less undesirable than those from fossil-fuel generators.
The transconjugant P13 strain was more efficient than either strain P13 or SZH16, and shows how plant growth-promoting bacteria which show no, or only limited, ability to degrade organic pollutants may be modified.
The agency's scientific advisory panel has recommended setting a high bar that could put hundreds of counties out of compliance with the law, forcing them to take action to reduce emissions, even though the pollutants may be generated beyond their jurisdiction.
Finally, the organic pollutants may be destroyed by these forming radicals.
