“…In this content, soil characterization (organic matter, moisture content of the soil and pH of the soil, etc.) is very important on the amount and distribution of pollution (Taoeli 2007;El-Fadel et al 1997;Daskalopoulos et al 1997;Tchobanoglous et al 1993). In the present study, the soil samples were collected from four locations (BH 1 to BH 4) with the distance of 200 m from the Ariyamangalam open dump site boundary.…”

“…Solid wastes are the organic and inorganic wastes generated by rapidly increasing production, consumption and other human and animal activities of the urban society, normally discarded as useless or unwanted or those that have lost their value to the first user and are a major cause of pollution (Berkun 1991;Mee and Topping 1998). Solid waste composition varies substantially with socio-economic conditions, location, season, waste collection and disposal methods, sampling and sorting procedures and many others factors (El-Fadel et al 1997). The increasing amounts of municipal solid waste generated each year in several industrialized countries have raised concerns about the economic viability and environmental acceptability of the current waste-disposal methodologies (Daskalopoulos et al 1998).…”

Assessment of heavy metal contamination in soil due to leachate migration from an open dumping site

2012

The concentration of heavy metals was studied in the soil samples collected around the municipal solid waste (MSW) open dumpsite, Ariyamangalam, Tiruchirappalli, Tamilnadu to understand the heavy metal contamination due to leachate migration from an open dumping site. The dump site receives approximately 400-470 tonnes of municipal solid waste. Solid waste characterization was carried out for the fresh and old municipal solid waste to know the basic composition of solid waste which is dumped in the dumping site. The heavy metal concentration in the municipal solid waste fine fraction and soil samples were analyzed. The heavy metal concentration in the collected soil sample was found in the following order:The presence of heavy metals in soil sample indicates that there is appreciable contamination of the soil by leachate migration from an open dumping site. However, these pollutants species will continuously migrated and attenuated through the soil strata and after certain period of time they might contaminate the groundwater system if there is no action to be taken to prevent this phenomenon.

“…Currently, the majority of food waste is incinerated with other combustible municipal wastes for heat or energy production, while residual ash is then disposed of in landfills. However, incineration is an expensive waste conversion technique, and can cause severe air pollution [4]. From an environmental viewpoint, there is an urgent need for appropriate management of food waste.…”

A Threshold-Based Weather Model for Predicting Stripe Rust Infection in Winter Wheat

et al. 2017

Food waste (FW) generally has high starch content and is rich in nutritional compounds, including lipids, proteins and acids. It is therefore potentially a renewable resource and its utilization for value-added product development is gaining interest. In this study, FW from a cafeteria was used as sole substrate for glucose production, and the fermentation conditions for optimum glucose yield were firstly optimized using response surface methodology. It was found that glucose yield was significantly affected by α-amylase loading, solid loading and temperature. The optimal conditions were found to be an α-amylase loading of 12.15 U/g FW, a solid loading of 22.4% and a culture temperature of 83.8°C for 90 min, which resulted in a maximum glucose yield of 217 mg/g. Secondly, in order to increase the final glucose concentration, an in situ produced fungal mash rich in glucoamylase was obtained from Aspergillus awamori which resulted in a glucose concentration of 99.1 g/L. When a fungal mash rich in cellulase obtained from Trichoderma reesei was combined with glucoamylase, a maximum of 140 g/L of glucose was obtained. This study showed that FW is a suitable substrate for saccharification with high conversion yield, indicating the potential utilization of food wastes for value-added chemicals production.

“…styrene (IARC, 1994) and lead (IARC, 1987a)) carcinogenic to humans. Leaching and runoff of waste decomposition products may occur (El-Fadel et al, 1997), not only while the site is being operated, but also after closure, as waste products continue to decay (Bozkurt et al, 2000). Human exposure to these releases potentially occurs via inhalation of polluted air, ingestion of contaminated water, or skin contact with contaminated water or soil.…”

Cancer risks in populations living near landfill sites in Great Britain

et al. 2002

Previous studies have raised concerns about possible excess risks of bladder, brain and hepatobiliary cancers and leukaemias near landfill sites. Several cancers have been implicated, but no consistent pattern has emerged. We present a large nationwide analysis of selected cancers near landfill sites in Great Britain. The base population comprised people living within 2 km of 9565 (from a total of 19 196) landfill sites that were operational at some time from 1982 to 1997, with populations living more than 2 km from a landfill as reference. Risks of cancers at the above sites were computed with adjustment for age, sex, year of diagnosis, region and deprivation. National post-coded registers provided a total of 341 856 640 person -years for the adult cancer analyses and 113 631 443 person -years for childhood leukaemia. There were 89 786 cases of bladder cancer, 36 802 cases of brain cancer, 21 773 cases of hepatobiliary cancer, 37 812 cases of adult leukaemia and 3973 cases of childhood leukaemia. In spite of the very large scale of this national study, we found no excess risks of cancers of the bladder and brain, hepatobiliary cancer or leukaemia, in populations living within 2 km of landfill sites. The results were similar if the analysis were restricted to landfill sites licensed to carry special (hazardous) waste. Our results do not support suggestions of excess risks of cancer associated with landfill sites reported in other studies.
