    Impact of carwash discharge on stormwater quality (Toulouse, France)

    The contribution of discharge from carwashes to pollutant levels in stormwater was evaluated. Five carwashes and two outlets in the city of Toulouse (France) were selected. Water samples were collected from December 2006 to December 2007. Concentrations and loadings of classical water quality parameters (conductivity, pH, turbidity, chemical oxygen demand, nitrogen, phosphorus, ammonium, nitrate, suspended solid and volatile suspended solid) and five groups of organic compounds (polycyclic aromatic hydrocarbons, polychlorinated biphenyls, lauryl alkyl benzene sulphonates, methyl tert-butyl ether and total hydrocarbons) were determined. The results suggest that the wastewater derived from carwashes was negligible compared to the volume and flow rates within the stormwater network. However, high concentrations of polycyclic aromatic hydrocarbons, phosphorus and lauryl alkyl benzene sulphonates in liquid waste from carwashes, and the impact of these pollutants on stormwater quality could not be neglected

    The Socioeconomic Gap in University Dropouts

    Get PDF
    In many countries, including the U.S. and the U.K., there is ongoing concern about the extent to which young people from lower-income backgrounds can acquire a university degree. Recent evidence from the U.K. suggests that for a given level of prior achievement in secondary school a disadvantaged student has as much chance of enrolling in a university as a more advantaged student. However, simply participating in higher education is not sufficient—graduation is important. Therefore, this paper investigates whether students from lower socioeconomic backgrounds have a higher rate of university dropout when compared to their wealthier counterparts, allowing for their differential prior achievement. Using a combination of school and university administrative data sets, we show that there is indeed a sizeable and statistically significant gap in the rate of withdrawal after the first year of university between advantaged and disadvantaged English students. This socioeconomic gap in university dropouts remains even after allowing for their personal characteristics, prior achievement in secondary school and university characteristics. In the English context, at least, this implies that retention in university of disadvantaged students is arguably a more important policy issue than barriers to entry for these students

    Impact of dry weather discharges on annual pollution from a separate storm sewer in Toulouse, France

    The city of Toulouse with its separate sewer system is ideal for studying stormwater. However, during dry weather, the storm sewer also discharges water into the environment, and it is the impact of these discharges on annual pollution from storm sewer that is the object of this study. Samples have been taken from the outlets of two storm drains located in heavily and moderately urbanized areas. Sampling has been undertaken during wet weather and during dry weather between January 2010 and February 2011. Three dry weather and two wet weather samples have been taken every three months and from each outlet. The overall pollution parameters have been analyzed (chemical oxygen demand, biological oxygen demand, total nitrogen, ammonium, nitrate, total phosphorus, suspended solid matter, volatile suspended matter, pH, conductivity, turbidity). Characterization has been completed by analysis of trace organic compounds: polycyclic aromatic hydrocarbons, total hydrocarbons, methyl tert-butyl ether, diethylhexylphthalate, nonylphenols, hormones (estradiol, ethinylestradiol). For certain parameters, the results obtained did not conform to legislative requirements concerning discharge into the natural environment. Correlations between these parameters have been studied, and identified between several of them using principal component analysis. The most important correlation observed was between conductivity and concentration in total phosphorus for one of the outlet. Results showed that dry weather had an impact on annual pollution load from separate storm sewer and that level of urbanization was also a factor. The effect of season has been studied but no significant impact was found

    The Determinants of Non-Cognitive and Cognitive Schooling Outcomes. Report to the Department of Children, Schools and Families

    Get PDF
    The Centre for the Economics of Education was asked to investigate the factors that influence a range of children's academic and non-academic outcomes, including their enjoyment of school, whether they take unauthorised absence from school and whether they feel they are bullied. The study also investigated whether schools can influence these non-academic outcomes. The study makes use of the Longitudinal Study of Young People in England, which is a survey of young people in secondary school that collects information on bullying, truancy and many other factors in each child's life. The data is linked to information on each child's academic achievement, enabling this study to investigate the inter-relationship between a pupil's academic performance and non academic outcomes. Pupils who enjoy school more at age 14 have, perhaps unsurprisingly, higher academic achievement by age 16. Equally, children who have higher achievement at age 11 go on to enjoy school more at age 16 though this is a not a strong relationship. In other words enjoyment of school and academic achievement are clearly linked. Pupils who were bullied or who took unauthorised absence at age 14 had significantly lower educational achievement at GCSE. Pupils who experienced bullying at age 14 were also much more likely to experience bullying at age 16. Therefore early negative outcomes, such as being bullied, suggest the child is at risk of having later negative experiences at age 16. Conversely, pupils who participate in positive extra-curricular activities, such as clubs, were also found to have better academic achievement later in their schooling. High achievers at school, i.e. pupils who do well academically at age 14, were also no more likely to be bullied at age 16 than other children. The report also investigated the impact of schools on some of these non-academic outcomes between 14-16 and found little evidence that schools currently have different impacts on pupil's enjoyment of school, nor whether they take unauthorised absence, nor their likelihood of being bullied. In other words, which school a pupil attends is likely to have small or no effect on their wider well-being. This does not mean that schools do not have the potential to impact on these factors but rather that currently there are not large differences across schools in these outcomes once socio-economic factors have been taken into account. The report concludes that non-academic factors, such as a pupil's enjoyment of school, are inextricably linked to pupils' academic achievement. We need to be aware of these relationships when considering policies to improve pupil achievement. The report also provides some useful risk indicators of future low pupil academic achievement. For example, some factors, such as being bullied or taking unauthorised absence, predict low future academic achievement. Again this can be used by schools and policy-makers to identify pupils at risk of low attainment. This research report was written before the new UK Government took office on 11 May 2010. As a result the content may not reflect current Government policy. This research will be of use to officials and ministers in helping to shape the future direction of policy and Departmental strategy.education, bullying
