Vertebrate fish are characterized by high levels of carcinogen metabolism, low body burdens of carcinogen, the formation of carcinogen-macromolecule adducts, and the occurrence of pollution-related tumors.
Rozell and Reaven (2012) studied five pathways of water contamination, assessing the probability of occurrence of water pollution and also advocating the need for further detailed studies.
This region presents a high occurrence of photochemical pollution events, which result from numerous industrial and urban sources of primary pollutants.
The present study has obviously demonstrated that there is a significant occurrence of bacterial pollution indicators and pathogenic bacterial groups in the Meenachil river.
Based on these results, we argue that the occurrence of environmental pollution in the Faynan valley is highly variable, and that the distribution of heavy metals resulted from a combination of natural and cultural factors, including persistent landscape features that helped contain the most polluted metallurgical deposits.
In Thailand, PEBs have been enthusiastically promoted but they have still not received much public attention, as evidenced by the degradation of ecosystems and the occurrence of environmental pollutions in some areas.
First, according to the statistical significance of source, transport, and attenuation factors dominating the occurrence of nitrate-N pollution, a LR model was adopted to evaluate aquifer vulnerability and to characterize occurrence probability of nitrate-N exceeding 0.5 mg/L.
There was however a relationship between days of ANY reliever use and the occurrence of a moderate/high pollution day.
Therefore, air pollution could affect the occurrence of HFRS, because air pollution is associated with changes in climate variables.
In addition, Monte Carlo simulation (MCS) and normal distribution function were used to evaluate the uncertainty of this parameter and the probability of pollution occurrence in the study area.
To characterize risk index affecting the study area, a novel approach was developed by combining both damage map which was obtained by multiplying seven hydrogeological parameters of modified DRASTIC model with pollution and probability of pollution occurrence with consideration of uncertainty.
