Hazardous materials released to water, land and air can pollute the environment and become even greater threats to peoples life. For instance, when rain falls on a waste site, it may carry the hazardous materials deep…

Some technologically advanced landfills also leak from time to time. The tanks used to store petroleum or chemicals can easily leak and catch fire. Tanks in the underground can weaken and leak their hazardous materials. There are many risks when transporting hazardous materials, for example, when trucks overturn or train crash. People can also dump hazardous materials in sewer systems, warehouses that are abandoned or remote areas, ditches to escape the costs of safe dumping. There are three routes of entry that hazardous materials enter into the body: ingestion, absorption, and inhalation (SYKLI, 2012).
Health risks commonly linked with hazardous materials are grouped as acute and chronic. It is a must for one to get medical attention when one is exposed to harmful materials. Most of these exposures have treatment if one takes immediate action.
Acute/ immediate effects result from a short-time exposure to hazardous substances. Some of the immediate warning signs include headaches, nausea, dizziness, skin, eye or respiratory damage or irritation, unconsciousness and even death. The most noticeable and common warning signs are skin, eye, and respiratory irritation. Occurrences of deaths are very rare, and the majority of these exposures can be treated if immediate attention is taken.
Chronic/delayed effects occur after a long time exposure to hazardous materials. The exposure can also be very small over a lengthened period. The effects mainly target the liver and kidneys as all chemicals that get into the body pass through these organs. A perfect example of an unending health effect is called lung cancer from radon inhalation or cigarette smoke.
There are some products that can cause large health risks, though used as directed. For instance, there are products taken off the market or banned due to their health or environmental risks, for example, those containing PCTs, PCBs, asbestos fibers, mercury, lead and arsenic

In general thickness of thin films is less than microns. These films are different from thick films. Throughout history, these films have been utilized for more than a half century for constructing different electronic components. These films are also used for the coating of different optical instruments, decoration of different parts and for coatings of hard materials.
The paper is focused on presenting the concepts and issues related to the hazardous effects of ionizing radiation by exploring the information available to the public and the information that can be gathered from academic and scientific resources. Ionizing radiation became known due to the hazardous effects to human health.
As discussed in this paper, titanium alloy exhibits high degree of tensile strength, low weight, and high resistance to corrosion, thermal strength and ease of fabrication at extreme temperatures. However, titanium is highly susceptible to dry chlorine gas, hypochlorite and reducing acids thus limits its production and uses.
They are also associated with the pollution of the environment. A hazardous material is defined as a substance that threatens to harm the environment or the public health. In the US, the treatment, disposal and storage of hazardous material is
There should be at least one portion of each in order to make a composite material.
The matrix surrounds the reinforcement material in the composite; therefore acting as a supporting agent. The reinforcement material on the other hand
This makes it ideal for kitchen usage where a single can and rarely as many as 60 are used at the same time.
Its production is rather interesting ad takes into consideration multiple aspects. These include aesthetic finish which is
stigation Board (2009), the cause of the hazard can be determined by investigating the raw materials, method of production, equipment and the employees among other things. Default in any factor involved in the production process causes a hazard occurrence. From the report of
At times, a hazard can be termed as being the actual harm or the health effect it caused. For instance, tuberculosis can be termed as a hazard by some people but the TB-causing bacteria is the one that should be considered as the hazard or the hazardous biological agent
