Stormwater harvesting for irrigation purposes: An investigation of chemical quality of water recycled in pervious pavement system

Most available water resources in the world are used for agricultural irrigation. Whilst this level of water use is expected to increase due to rising world population and land use, available water resources are expected to become limited due to climate change and uneven rainfall distribution. Recycled stormwater has the potential to be used as an alternative source of irrigation water and part of sustainable water management strategy. This paper reports on a study to investigate whether a sustainable urban drainage system (SUDS) technique, known as the pervious pavements system (PPS) has the capability to recycle water that meets irrigation water quality standard. Furthermore, the experiment provided information on the impact of hydrocarbon (which was applied to simulate oil dripping from parked vehicles onto PPS), leaching of nutrients from different layers of the PPS and effects of nutrients (applied to enhance bioremediation) on the stormwater recycling efficiency of the PPS. A weekly dose of 6.23×10-3L of lubricating oil and single dose of 17.06g of polymer coated controlled-release fertilizer granules were applied to the series of 710mm×360mm model pervious pavement structure except the controls. Rainfall intensity of 7.4mm/h was applied to the test models at the rate of 3 events per week. Analysis of the recycled water showed that PPS has the capability to recycle stormwater to a quality that meets the chemical standards for use in agricultural irrigation irrespective of the type of sub-base used. There is a potential benefit of nutrient availability in recycled water for plants, but care should be taken not to dispose of this water in natural water courses as it might result in eutrophication problems. © 2014 Elsevier Ltd

Relationships Between Energy Availability, Dietary Restraint, and Body Image Concerns among Olympic Weightlifters

Athletes with low energy availability (LEA) may face reduced health and performance outcomes. Few studies have examined the energy availability (EA) of Olympic weightlifters and its relationships with nutrient adequacy, disordered eating, and body image. PURPOSE: To evaluate EA among weightlifters and to examine the relationship between LEA with dietary restraint and/or body image concerns. METHODS: Twenty-two female and 9 male adult competitive weightlifters (age 30.7 ± 9.0 years; weight 75.5 ± 16.6 kg; height 1.6 ± 0.1 m) completed an online survey. The Nutrition Screening Survey (NSS) assessed nutrient intake and EA. Athletes were classified as having EA \u3c 30 kcal/kg FFM/d or EA ≥ 30 kcal/kg FFM/d. The Eating Disorder Examination Questionnaire (EDE-Q) and Drive for Muscularity Scale (DMS) assessed dietary restraint and body image concerns. RESULTS: Female athletes with EA \u3c 30 kcal/kg FFM/d exhibited significantly higher dietary restraint (2.23 ± 0.65) compared to those with EA ≥ 30 kcal/kg FFM/d (1.22 ± 1.20, p = .02). No significant difference in weight concern, shape concern, or drive for muscularity was observed according to EA status (EA \u3c 30 vs. EA ≥ 30 kcal/kg FFM/d). Female weightlifters had higher weight (1.50 ± 1.49 vs. 0.53 ± 0.69; p = .02) and shape concern scores (2.22 ± 2.19 vs. 0.77 ± 0.82; p = .01) compared to male weightlifters. The drive for muscularity scores did not significantly differ between male and female weightlifters (3.63 ± 0.99 and 3.46 ± 0.72, p = .58). CONCLUSION: In female weightlifters, the relationship between dietary restraint and EA may potentially be used as a proxy to identify low EA. Further assessment of diet adequacy, dietary restraint, and body image among weightlifters is necessary

Challenges and opportunities in the design and construction of a GIS-based emission inventory infrastructure for the Niger Delta region of Nigeria

© 2017, Springer-Verlag Berlin Heidelberg. Environmental monitoring in middle- and low-income countries is hampered by many factors which include enactment and enforcement of legislations; deficiencies in environmental data reporting and documentation; inconsistent, incomplete and unverifiable data; a lack of access to data; and technical expertise. This paper describes the processes undertaken and the major challenges encountered in the construction of the first Niger Delta Emission Inventory (NDEI) for criteria air pollutants and CO2 released from the anthropogenic activities in the region. This study focused on using publicly available government and research data. The NDEI has been designed to provide a Geographic Information System-based component of an air quality and carbon management framework. The NDEI infrastructure was designed and constructed at 1-, 10- and 20-km grid resolutions for point, line and area sources using industry standard processes and emission factors derived from activities similar to those in the Niger Delta. Due to inadequate, incomplete, potentially inaccurate and unavailable data, the infrastructure was populated with data based on a series of best possible assumptions for key emission sources. This produces outputs with variable levels of certainty, which also highlights the critical challenges in the estimation of emissions from a developing country. However, the infrastructure is functional and has the ability to produce spatially resolved emission estimates
