Deconstruction of annoyance due to air pollution by multiple correspondence analyses

Annoyance caused by air pollution is a matter of public health as it can cause stress and ill-health and affect quality of life, among other burdens. The aim of this study is to apply the multiple correspondence analyses (MCA) technique as a differential tooling to explore relationships between variables that can influence peoples’ behaviour concerning annoyance caused by air pollution. Data were collected through a survey on air pollution, environmental issues and quality of life. Face-to-face survey studies were conducted in two industrialized urban areas (Vitoria in Brazil and Dunkirk in France). These two regions were chosen as their inhabitants often report feeling annoyed by air pollution, and both regions have similar industrial characteristics. The results showed a progressive correspondence between levels of annoyance and other active variables in the “air pollution” factor group: as the levels of annoyance increased, the levels of the other qualitative variables (importance of air quality, perceived exposure to industrial risk, assessment of air quality, perceived air pollution) also increased. Respondents who reported feeling annoyed by air pollution also thought that air quality was very important and were very concerned about exposure to industrial risks. Furthermore, they often assessed air quality as horrible, and they could frequently perceive air pollution by dust, odours and decreased visibility. The results also showed a statistically significant association between occurrence of allergies and high levels of annoyance.

Locating Existing Best Management Practices Within a Watershed: The Value of Multiple Methods

There is an increasing need to document the impacts of conservation‐related best management practices (BMPs) on water quality within a watershed. However, this impact analysis depends upon accurate geospatial locations of existing practices, which are difficult to obtain. This study demonstrates and evaluates three different methods for obtaining geospatial information for BMPs. This study was focused on the Eagle Creek Watershed, a mixed use watershed in central Indiana. We obtained geospatial information for BMPs through government records, producer interviews, and remote‐sensing aerial photo interpretation. Aerial photos were also used to validate the government records and producer interviews. This study shows the variation in results obtained from the three sources of information as well as the benefits and drawbacks of each method. Using only one method for obtaining BMP information can be incomplete, and this study demonstrates how multiple methods can be used for the most accurate picture.     

Occupational safety conditions of bus drivers in Metro Manila,the Philippines

The study looks into the occupational safety and working conditions among bus drivers in Metro Manila, the Philippines. Quantitative data were collected through survey interviews of 95 bus drivers using the stratified sampling technique. Results showed that bus drivers worked an average of 16?h/day and were engaged in risky driving behaviors such as over-speeding and road racing in order to reach their quota for the day. Fifty-nine percent experienced work-related accidents, with a mean of three accidents. The most common accident was hitting another vehicle followed by side swipe. The accidents were blamed on other drivers, followed by vehicle defect, inattentiveness and tiredness/micro-sleep or sudden involuntary sleep while driving. The most common health symptoms experienced by the bus drivers were fatigue, back pain, and cough and colds. This study underlines the need for an occupational health and safety program for bus drivers in the Philippines.     

Juvenile sea bass (Dicentrarchus labrax L.) DNA strand breaks and lipid peroxidation response following 17beta-estradiol two mode of exposures

Juvenile Dicentrarchus labrax L. (sea bass) were exposed to water diluted 17beta-estradiol (E2) (200 ng/L and 2000 ng/L) and treated with intraperitoneal (i.p) injection E2 (0.5 mg/kg and 5 mg/kg) during 10 days in order to study its genotoxicity and peroxidative damage, measured as gill, blood, liver and kidney DNA integrity decrease using DNA strand breaks assay as well as liver, gill and kidney lipid peroxidation (LPO) respectively. Juvenile sea bass gill DNA integrity was significantly decreased for all E2 exposure conditions. However, no differences were detected either between different exposure routes or tested concentrations. Blood DNA integrity was significantly decreased by E2 5 mg/kg as well as by both water diluted E2 exposure conditions. The highest E2 dose (5 mg/kg) also promoted liver DNA integrity decrease. Liver and gill LPO significantly increased at the highest E2 i.p treatment. An increasing trend of gill and liver LPO, though statistically insignificant, was observed in D. labrax exposed to water diluted E2 in both tested concentrations. The current results demonstrated that DNA damage in juvenile sea bass is affected by the E2 exposure conditions, such as water diluted E2 versus i.p E2 injection since i.p E2 injection promoted higher genotoxicity effect, in terms of affected organs than water diluted E2. Moreover, the organ sensitivity to E2 was different, since gill showed more susceptibility than blood, liver and kidney. Concerning kidney LPO and DNA integrity no differences were found between treated and controls juvenile sea bass groups.
