TSCA Definitions By TSCA Definitions PCB’S: Polychlorinated biphenyls (PCBs) refers to a family of 209 congeners of structurally alike organic chemicals, which range from oily liquids to waxy solids. PCBs can be either toxic or non-toxic, there are 12 PCBs that are dioxin-like. One dioxin-like PCB is 3,4,4,5- Tetrachlorobiphenyl. PCBs are produced either as a singular congener or as a homogeneous group, or as a mixture. PCBs are normally synthetic in nature. The main characteristics of PCBs are, they are non-flammable, they have a high boiling point, they are stable, and they exhibit e...

...Chlorofluorocarbons and sulfur dioxide. Methane gas is another byproduct of human consumption in the form of the cattle industry and a major contributor to greenhouse gas levels. Chlorofluorocarbons, commonly... Air Pollution Cause and Effects The term Air pollution refers to toxins permeating the atmosphere due to industrial and vehicle waste emissions. The tons of pollutants being pumped into the air every year result in destructive effects that are severely harming the health of people and the earth. The direct effect is evident to anyone who has lived in or near a major city. The skies are off-color and ozone warnings are common. People who are susceptible to lung-related issues such as asthma or...

...chlorofluorocarbons, etc.), air pollution, and the escalating dilution of air particles (American Institute of Physics, “Statements on the Human Impacts on Climate Change”). Main causes of the increasing concentration of greenhouse gases and other airborne particles are attributable mainly to the enormous carbon emission levels of fossil fuel combustion, aerosols, and the production of cement. Greenhouse gases, which are considered to be forced by human activities, contribute to the perceived global warming in the last half-century” (Hegerl, “Understanding and Attributing Climate Change”). Furthermore, the existing increase on the Earth’s carbon... ? 13 November Human Influence on Climate Change and Its...

Effects of Environmental Pollution Pollution can be defined as the introduction of contaminants into a natural environment. The world today is marred by the adverse effects of environmental pollution. Year in year out, the world faces grave and irreparable damages as a result of environmental pollution. Myriads of deaths occur as a result of health effects related to pollution. The effects range form mild discomforts to chronic diseases such as cancer. Human health has been endangered to large extents. Thus, the effects of pollution to the world are self-evident. This paper analyses these effects...

...chlorofluorocarbons, methane, carbon monoxide and other gases regarded as greenhouse gases do contribute to the entire global warming. 61. Some structures are only found in plant and not in animals these includes; Cell wall, chloroplast, and cell vacuole. The cell wall helps in the maintenance of turgor pressure experienced by the plant cell when they imbibe more water. The chloroplasts on the other hand do help the plant with the provision of chlorophyll with is the sole light trapper for the process of photosynthesis to take place. The cell vacuole also plays a very important role in the maintenance of the plant structure. 62. The term biome is used to refer to the...
