The impact of legislation on health,safty and environmental aspects of Essay

The impact of legislation on health,safty and environmental aspects of surface coatings - Essay Example Recently, the CEN Technical Board directed that the European standard work item should include assessment of the environmental aspect. The evaluation should be undertaken between Stage 11 (work allocated to Technical Body) and Stage 32 (working document circulated to Technical Body). This can be done by accomplishing a checklist provided by the CEN pertaining to environmental aspect. The checklist serves to ensure that the environmental aspects are in line with CEN directive seen in its system handbook guidelines. Similar to this, the ISO has come up with the ISO Guide 64 which calls for life cycle assessment to assess the environmental impact and recognized scientific technique used. (Wallstrom 2000) In terms of standards for paints and varnishes, the environmental aspect involves the minimization of pigment concentration, dispersion, grinding time and method, and durability among others. Moreover, the use of volatile organic compounds is highlighted. In relation to this, standards set acknowledge the fact the use of VOC in this industry may not entirely be avoided. However, the use of less harmful substances is encouraged. (Wallstrom 2000) The health and safety aspects concentrate on the use of reagents. The standards call for the substitution of aromatic compounds used for cleaning purposes whenever possible and the substitution of aliphatic solvent with vegetable ester with or without emulsifier. (Wallstrom 2000) All in all, majority of the technical standards set by both CEN and ISO for paints or surface coatings are focused on the test methods. However, it should be noted that these standards under test methods do not include much about environmental aspect unlike the standards for products and processes. Standards for products especially have significant impact on the choice of system and strongly encourage compliance with local and international legislations implemented.

Core and Periphery or GMOs, Traditional Foods and Indigenous Essay

Core and Periphery or GMOs, Traditional Foods and Indigenous Sovereignty or Migration and Climate Change - Essay Example ed trivial instances of malnutrition and poverty due to the self-sufficient production of its staple foods, wheat and rice (Newman, â€Å"Will Climate Change Spark Conflict in Bangladesh?†). To that end, overpopulation is not a matter of concern to the Bangladeshis. Changes in climate involving chaotic storms, droughts and ever-increasing sea levels have turned the nation into the most vulnerable country to climate changes. These factors are stealing away the land of the larger population that lives in the coastal regions, such as Dakope. In addition, the largest delta in the, Ganges Delta, that empties much of the Himalayas water has shown the signs erosion. Here, palm trees grow out of the rivers, fields full of salt particles and many brick foundations laced into halves (â€Å"Will Climate Change Spark Conflict in Bangladesh?†). Practically, the land occupied by water was once dry and people lived on it. The rise in the sea levels prompts people to migrate to other p laces in the country and even abroad with an intention of finding better settlement. Greenhouse gases emissions and rising temperatures are the major cause of climate changes. Reports asserts that Bangladesh only contributes 0.3 percent of the emissions and yet it is the most hit as regarding to climate changes. Other environmental degradations spring from the tragedy encountered in Bangladesh. The Bangladeshis depend merely on the ground water since most of the rivers in the nation are polluted, a move that is per se right. The result of excessive pumping of water from the ground is that the land settles sinks. Floods are a common feature in this nation since as sea levels rise, the land level is also sinking. Besides, the sea walls are constructed poorly, a factor that increases the risk of flooding. The frequent cyclones experienced in the neighboring Bay of Bengal are detrimental to the environment conditions of Bangladesh (Harris, â€Å"Borrowed Time on Disappearing Land†). As a mechanism of
