Hazardous waste essee

Steve Astok If we are poisoning the Earth, then we are poisoning ourselves Hazardous waste is one of today's biggest environmental problems. The waste poses substantial threats to public health and to the environment. Hazardous waste is mostly produced by major industries. Almost all industries have to get rid of the waste that has been produced due to their work. Mostly, it is difficult and expensive to get rid of the waste so that it does not endanger the environment or human lives. Many industries create landfills to store waste and quite often the new landfill is near the water. The levels of dangerous waste continue to grow thanks to individuals too. Some...

Keskkonnaprobleemid

Effects of Marine Oil Spills Oil spills can have a serious economic impact on coastal activities and on those who exploit the resources of the sea. In most cases such damage is temporary and is caused primarily by the physical properties of oil creating nuisance and hazardous conditions. The impact on marine life is compounded by toxicity and tainting effects resulting from the chemical composition of oil, as well as by the diversity and variability of biological systems and their sensitivity to oil pollution. Impact of oil on coastal activities The effects of a particular oil spill depend upon many factors, not least the properties of the oil. Contamination of coastal amenity areas is a common feature of many spills leading to...

European Union

Union does not decide the content of schooling programs, but guarantee that acquired education and qualification will be accepted in other EU member states. Because pollution doesn't recognize borderlines the member countries of EU have taken common measures in many areas. Therefore it's not surprising that the rivers and beaches of Europe have become cleaner, the mashines pollute less and there have been established strict rules on waste treatment. Europe doesn't store it's hazardous waste in poor countries anymore. There are also strict rules in EU that ensure the safety of chemicals in usage for humans and the environment. EU leaders have an strict agreement how to minimum global warming by lessen greenhouse gases to 20% in 2020. Thanks to 50 years exist and arosed communion is war between EU countries quite thoughtless.. Get inspired from success, EU help try to keep peace and stability behind European Union boarders.

Energeetika arengu plaanimine

Disadvantages * The big problem is that there are not many places where you can build a geothermal power station. You need hot rocks of a suitable type, at a depth where we can drill down to them. The type of rock above is also important, it must be of a type that we can easily drill through. * Sometimes a geothermal site may "run out of steam", perhaps for decades. * Hazardous gases and minerals may come up from underground, and can be difficult to safely dispose of. Biomass Energy Biomass is biological material derived from living, or recently living organisms. In the context of biomass for energy this is often used to mean plant based material, but biomass can equally apply to both animal and vegetable derived material. Biomass is carbon based and is composed of a mixture of organic molecules containing hydrogen,...

Carbon capture and storage

This technology is really new and it is unknown to people. It has not been proven yet, so people are scared and concerned about it. The biggest fear is that carbon dioxide will leak out but we don't have to be worried about that, because CO2 is everywhere around us and it is not poisonous. But still, if we have very concentrated carbon dioxide, it is hazardous and that's purpose of monitoring. Rick Russell sees no definite risk associated with the release or damage either to the surface, soils or ground water, because the type of geology they are useing, will protect the planet from this happening. For now, they have given investment sanction to two projects ­ one in Norway in partnership with thw government there and with Statoil, and the anaother one in Australia. Prof. Martin Blunt is sure that if they cannot get...

Addiction and drugs

But using marijuana at a young age can result in structural and functional deficits of the brain. This could cause you to develop weakened verbal and communication skills, lowered learning capabilities and a shortened attention span. In addition to the possible effects on your brain, smoking marijuana may also be hazardous to your developing lungs. Marijuana smoke contains 50% to 70% more carcinogenic hydrocarbons than tobacco smoke. You may have heard people argue that marijuana is a "gateway drug" to harder drug use. Some say this is a myth, others insist it is a fact. The truth is that there is a link. Research shows that the earlier you start using marijuana, the more likely you are to become dependent on it or other types of drugs later in life....

Soil microflora

Fertilizers and manures applied to the soil for increased crop production, supply food and nutrition not only to the crops but also to microorganisms in soil and thereby proliferate the activity of microbes. Foliar or soil application of different chemicals (pesticides, fungicides, nematicides etc.) in agriculture are either degraded by the soil organisms or are liable to leave toxic residues in soil which are hazardous to cause profound reduction in the normal microbial activity in the soil. 2. Soil fertility: Fertility level of the soil has a great influence on the microbial population and their activity in soil. The availability of N, P and K required for plants as well as microbes in soil determines the fertility level of soil. On the other hand soil micro flora has greater influence on the soil fertility level. 3...

Dioxins and furans in the atmosphere

The newborn, with rapidly developing organ systems, may also be more vulnerable to certain effects. Some individuals or groups of individuals may be exposed to higher levels of dioxins because of their diets (e.g., high consumers of fish in certain parts of the world) or their occupations (e.g., workers in the pulp and paper industry, in incineration plants and at hazardous waste sites, to name just a few).

TEHNOÖKOLOOGIA EKSAM

Selle asemel lasevad nad tootjatel ise otsustada, kuidas neil oleks kõige parem WEEE nõudeid täita. Näiteks kehtestab Leedu valitsus igal aastal e-jäätmete tagasivõtmise kohustusliku määra ning kui tootjad selle saavutavad, ongi nad WEEE nõuded täitnud (Sander jt, 2007). 2003. aastal võttis Euroopa Liit vastu veel ühe seaduse. See on Teatud ohtlike jäätmete vähendamise seadus (Reduction of the Use of Certain Hazardous Substances ­ RoHS). See seadus seab piirmäärad mürgiste ainete kasutamisele elektrooniliste seadmete valmistamisel. RoHS toetajad väidavad, et selliste ohtlike ainete nagu plii, elavhõbeda ja kaadmiumi kasutamisest loobumine tootmises on looduskeskkonnale hea. See muudab ka jäätmete käitlemise edaspidi ohutumaks. Veelgi enam - RoHS lubab vähendada e-jäätmeid ülemaailmses ulatuses. Kui Hiina,...
