Correlation Between Occurrence and Deterioration of Respiratory Diseases and Air Pollution Within the Legally Permissible Limits.
The aim of the study was to investigate the unknown effect of air pollutants on the occurrence or deterioration of respiratory diseases in the area with a humid continental climate. This retrospective study included 5868 patients with respiratory symptomatology (upper respiratory tract infection (URTI), pneumonia, acute bronchitis, chronic obstructive pulmonary disease (COPD), and asthma) admit...
متن کاملGeoengineering, Ocean Fertilization, and the Problem of Permissible Pollution
Many geoengineering projects have been proposed to address climate change, including both solar radiation management and carbon removal techniques. Some of these methods would introduce additional compounds into the atmosphere or the ocean. This poses a difficult conundrum: Is it permissible to remediate one pollutant by introducing a second pollutant into a system that has already been damaged...
متن کاملDevelopment of permissible exposure limits: the California experience.

The model used offers important benefits. First, by allowing open meetings, the process was transparent, and input could be offered by concerned stakeholders. Second, the process was data-driven and, there...
متن کاملEvaluation of multiple sewage-associated Bacteroides PCR markers for sewage pollution tracking.
The host specificity of the five published sewage-associated Bacteroides markers (i.e., HF183, BacHum, HuBac, BacH and Human-Bac) was evaluated in Southeast Queensland, Australia by testing fecal DNA samples (n=186) from 11 animal species including human fecal samples collected via influent to a sewage treatment plant (STP). All human fecal samples (n=50) were positive for all five markers indi...
متن کاملStrategic management of non-point source pollution from sewage sludge.
In the UK, the recycling of sewage sludge to land is expected to double by 2006 but the security of this route is threatened by environmental concerns and health scares. Strategic investment is needed to ensure sustainable and secure sludge recycling outlets. At present, the security of this landbank for sludge recycling is determined by legislation relating to nutrient rather than potentially ...
