Analysis Of Waste Disposal Research Articles

Perception of the general population in Ciudad Valles, San Luis Potosi regarding waste production in hairdressing salons

Hairdressing salons offer a wide range of services including treatments for hair and skin. However, these activities result in the production of residues that are improperly discharged into drainage, generating a negative impact on the environment. This study provides results of a first stage in a project regarding the analysis of waste disposal in hairdressing salons in the municipality of Ciudad Valles, San Luis Potosi, Mexico. Information gathering was conducted through a field work study by surveys given to workers in hairdressing salons in Ciudad Valles. The information presented in this study indicates that in hairdressing salons in Ciudad Valles there is no management plan for the management of waste that could be severely impacting the environment. The information presented here will be the basis for identifying priority areas for intervention, developing new research projects and setting new environmental policies. In addition, the results presented here can be extrapolated to many rural and urban areas all over Mexico.

Toward a community coastal sediment transport modeling system: The second workshop

Models for transport and the long‐term fate of particles in coastal waters are essential for a variety of applications related to commerce, defense, public health, and the quality of the marine environment. Examples include: analysis of waste disposal and transport and the fate of contaminated materials; evaluation of burial rates for naval mines or archaeological artifacts; prediction of water‐column optical properties; analysis of transport and the fate of biological particles; prediction of coastal flooding and coastal erosion; evaluation of impacts of sea‐level or wave‐climate changes and coastal development; planning for construction and maintenance of navigable waterways; evaluation of habitat for commercial fisheries; evaluation of impacts of natural or anthropogenic changes in coastal conditions on recreational activities; and design of intakes and outfalls for sewage treatment, cooling systems, and desalination plants.

Radiological criteria for the disposal of solid radioactive wastes

Radioactive waste disposal is only one cause of exposure to ionizing radiation. Criteria for control should fit into the world-wide system for protection against radiation hazards, developed by the International Commission on Radiological Protection over the past 50 years. The system is simple and logically inevitable for any non-threshold pollutant. It consists of limits to protect individuals against unacceptable risks and a requirement to reduce the overall impact of the source causing the radiation to a level that is ‘as low as reasonably achievable’. Particular aspects examined in the paper include the long timescales of concern and the role of comparisons with natural levels of radiation. The output of radiological assessment is an input to broader decisions on waste management, accommodating environmental pressures within political judgements. It is necessary to pursue the scientific analysis of waste disposal so that the results can be used as a firm foundation to confront, openly and honestly, the concerns of the public and of the politicians.
