Snow pollution management in urban areas: an idea whose time has come?

The study investigated on the plastic pollution management: A panacea for Nigerias untapped waste to wealth growth: A study of some selected urban cities in south east Nigeria Enugu, Owerri, Awka and Umuahia. The specific objectives include to: examine the extent management of plastic waste have aided employment generation in some urban areas in South East, Nigeria, Nigeria determine the extent value chain network of plastic management has aided wealth creation in some urban areas in South East, Nigeria. The study adopted a cross sectional survey. The study instrument includes Garbage picking kits, health hazard prevention materials, waste selector machines, questionnaire, video coverage and security kits to help the research attendants for easy identification. Procedure: The study identified various dump sites across the cities mentioned. Out of a population of 6,454 staff, the sample size of 1096 was chosen after applying the Freund and Williams formula for the determination of adequate sample size. Out of the sample size of 912 returned the questionnaire and accurately filled. That gave 83 percent response rate. The validity of the instrument was tested using content analysis and the result was good. The reliability was tested using the Pearson correlation coefficient (r). It gave a reliability co-efficient of 0.85 which was also good. Data was presented and analyzed by mean score (3.0 and above agreed while below 3.0 disagreed) and standard deviation using Sprint Likert Scale. The hypotheses were analyzed using Z- test statistics tool. The findings of the reveals that management of plastic waste has positive effect on employment generation in some urban areas in South East, Nigeria r (85, n = 1096) = 24.471, p < 0.05 value chain network of plastic management had positive effect on wealth creation in some urban areas in South East, Nigeria r (85, n = 1096) = 46.882, p < 0.05. The study concluded that in order for solid waste management and plastic production systems to coevolved towards maximizing recycling as a strategy for plastic waste management. The study recommended among others, that there is a need to formulate and enforce a plastic bag regulation primarily to do away with the menace and to guide any such endeavors.

Hazardous Pollutants

Environmental context Trafficked streets are air pollution hot spots where people experience high exposure to hazardous pollutants. Although monitoring networks provide crucial information about measured pollutant levels, the measurements are resource demanding and thus can be performed at only few selected sites. Fast and easily applied street pollution models are therefore necessary tools to provide information about the loadings in streets without measurement activities. We evaluate the Operational Street Pollution Model, one of the most commonly applied models in air pollution management and research worldwide. Abstract Traffic emissions constitute a major source of health hazardous air pollution in urban areas. Models describing pollutant levels in urban streets are thus important tools in air pollution management as a supplement to measurements in routine monitoring programmes. A widely used model in this context is the fast and easy to apply Operational Street Pollution Model (OSPM). For almost 20 years, OSPM has been routinely used in many countries for studying traffic pollution, performing analyses of field campaign measurements, studying efficiency of pollution abatement strategies, carrying out exposure assessments and as reference in comparisons to other models. OSPM is generally considered as state-of-the-art in applied street pollution modelling. This paper outlines the most important findings in OSPM validation and application studies in literature. At the end of the paper, future research needs are outlined for traffic air pollution modelling in general but with outset in the research performed with OSPM.

Pollution Management

Air pollution is one of the biggest challenges for human health, and this is especially true for PM2.5 pollution in developing countries like China. Much of the PM2.5 research has been conducted in urban areas, but most tourist attractions are outdoors and outside cities and have been left out of related studies, leaving tourists unaware of the deadly air. To fill this gap, we investigated monthly PM2.5 concentrations in all of China’s outdoor tourist attractions. Our results indicated that summer is the healthiest time to travel in the Northeast, South, Southwest, and Northwest of China. Without air pollution management, our results also indicated that more than one third of the outdoor attractions would become unhealthy throughout the year. Thus, our work provides medical information to suggest that all tourists schedule China travel during periods of healthy air quality and also calls for instant air pollution management in China and beyond.

Individual Use

Cannabis use does not show homogeneous patterns in a country. In particular, urbanization appears to influence prevalence rates, with higher rates in urban areas. A hierarchical linear model (HLM) was employed to analyze these structural influences on individuals in Switzerland. Data for this analysis were taken from the Switzerland survey of Health Behavior in School-Aged Children (HBSC) Study, the most recent survey to assess drug use in a nationally representative sample of 3473 15-year-olds. A total of 1487 male and 1620 female students indicated their cannabis use and their attributions of drug use to friends. As second level variables we included address density in the 26 Swiss Cantons as an indicator of urbanization and officially recorded offences of cannabis use in the Cantons as an indicator of repressive policy. Attribution of drug use to friends is highly correlated with cannabis use. The correlation is even more pronounced in urban Cantons. However, no association between recorded offences and cannabis use was found. The results suggest that structural variables influence individuals. Living in an urban area effects the attribution of drug use to friends. On the other hand repressive policy does not affect individual use.
