Class C, and Class D. If exposed, to Class A, Class B , or Class C, humans may experience toxic effects such as; severe respiratory distress, increased heart rates, dizziness, and anemia. Different classes of crude oil spills may affect different species differently, including marine mammals, birds, and plantlife that may be near the oil spill. Marine life may become poisoned by the toxic contaminants in their environment. The oil spill that took place in the Gulf of Mexico in 2010 has harmed, or
Introduction Cancer is one of the oldest genetic diseases known to man. Since the evolution of mitosis as a means for cell division and the development of multicellular eukaryotes - like humans and their biological progenitors - mutations in normal cell maturation and proliferation have resulted in various types of cancers, some benign but many of which exhibit great malignancy (Hajdu, 2011). Cancer, and one of its more common forms carcinoma, is characterized as a genetic disease where by mutations
enveloping the city is the most visible and obvious sign of urban pollution. However, even invisible harmful particles can have a big impact on the quality of airspace. In general, any substance released into the environment and having an adverse effect, is an air pollution. Hazardous substances present in the air, not only affect the environment but to a greater extent on the person who breathes it. Nitrogen dioxides and carbon monoxide are two wildly known factors of global polluting of Earth.
from below the Earth’s surface using machinery and technology, some of which may be decades old – but as technology has proven itself to be unreliable at times, accidents such as oil spills are inevitable. Oil spills have devastating detrimental effects, both towards humans and other animals, as well as the environment. For example, drinking water may be polluted and marine life killed, consequently lowering the quality of life in affected areas. As the quality of the environment is inextricably
in the removal of contaminants from soil. However, true scientific study and development of these plants unique qualities was not conducted until the early 1980’s. (Lasat, 2000) At this time it was recognized that certain species of plants could accumulate high levels of heavy metals from the soil while continuing to grow and proliferate normally. (Lasat, 2000) Although research has been slow and tedious due to scientists’ incomplete understanding of the generalized cellular mechanisms of plants
The null hypotheses stated that there is no difference in the classification (or detection) of common indoor fungal contaminants for different electronic nose pattern recognition algorithms: π1 = π2 = π3 = π4. The alternative hypotheses stated that there is a difference in the classification (or detection) of common indoor fungal contaminants for different electronic nose pattern recognition algorithms: πa ≠ πb; 1 ≤ a, b ≤ 4. I established the significance level at the commonly
