Potentially big: A superior court in Hyde County, N.C., ruled that the state has authority to require Rose Acre Farms, a facility housing nearly four million egg-laying hens, to be regulated under the federal Clean Water Act because of pollutants released from ventilation fans in the henhouses.
The thing is, if they build this [development] and people are getting sick because of pollutants that the Housing Authority knows about now, there's tremendous liability for them down the road".
The report cautioned that in many cases the data were "very limited". In those 49 countries, representing about two-thirds of the world's population, they estimated more than 17 million years of healthy life were lost because of pollutants caused by the 10 industries examined, compared to 14 million for malaria, 25 million for tuberculosis and nearly 29 million for HIV.
The total sample number per pollutant differed slightly because of pollutant-specific data invalidations (Table 2).
Because the spatial distribution of pollutant concentrations was similar from one day to the next the three metrics were well-correlated over time; consequently the chi-square statistics from the time-series models were similar across metrics.
DME (dimethyl ether, CH3OCH3) is a potentially attractive fuel for gas turbines because of low pollutant emission and easy transportation and storage.
We chose SIC code 2752, representing commercial lithographic printing, because it released one type of pollutant rather than multiple classes of pollutants.
We excluded 4931 events (6.2%) from the multi-pollutant model because of missing pollution data; for single pollutant models, the number of events excluded ranged from 1952 (2.5%) to 2447 (3.1%) depending on the pollutant (further details in web appendix).
This is because the amount of pollutants emission would be confined in a certain level and coal-fired electricity conversion technology corresponds to a higher pollutants emission rate than natural gas-fired conversion technology.
The unsaturated zone, described as the portion between the ground surface and groundwater (Freeze and Cherry 1979), is of key interest because the transmission of pollutants to groundwater occurs through it.
