Ecological damage

A hazardous waste characteristic is a property that indicates that a waste poses a sufficient threat to deserve regulation as hazardous. U.S. EPA tried to identify characteristics that, when present in a waste, can cause death or illness in humans or ecological damage. U.S. EPA also decided that the presence of any characteristic of hazardous waste should be detectable by using a standardized test... 

As noted by Wolman ( 3), educational institutions are continually asked to prepare those who will search for solutions of societal problems. Problems in the real world do not separate nicely into "disciplines". We do not see the "botany problem", or the "meteorology problem", or the "chemical engineering problem", as such. Rather, we see a minor by-product from a facility designed by a chemical engineer. Released, it is transported by meteorological processes, and becomes of concern because a botanist foresees ecological damage as a consequence of its downwind presence. Thus while disciplines and departments in universities are an administrative convenience and provide a perhaps needed foundation for specialized research and education, educational institutions also must address problems which do not fit nicely into present disciplinary units. 

Lawn people are anxious. Their worries about over-consuming chemicals and wreaking ecological damage as a result of their choices are directly correlated with their behaviors indeed such worries are fundamental to them. Are these anxieties a vehicle for critical change Or are these concerns instead a necessary and logical product of the system through which lawn people are subjected, rather than external to it ... 

Although many people sustained minor, short-term effects such as headaches and nausea, no serious or long-term damage to the health of the local population was detected. Severe ecological damage was caused to the river over a distance of about 155 miles (250 km), including the death of large numbers of fish and eels. 

However, there is a need for better tests to assess ecological damage potentially caused by single-compound chemicals, the byproducts of various waste treatment processes, and the degradation products of intentional processes or unintentional process emissions that find their way into the environment.

Serious environmental damage is also associated with many types of industrial husbandry of livestock. For example, serious ecological damage may be caused by the disposal of sewage and other wastes, and by the use of pesticides and other cultural practices to grow the enormous quantities of fodder required as food by the livestock. 

In addition to the various native members of the minnow family, several species have been introduced to North America. The most familiar introduced species is the common carp Cyprinus carpio). This fish is commonly cultivated as food in Europe and Asia, and it was released to many North American lakes in the hope of establishing a food resource that many immigrants would like to eat. Unfortunately, the common carp has caused some important ecological damage in many of the waterbodies where it has become established, resulting in the displacement of native species of fish and other animals and damage to aquatic vegetation. 

The goldfish Carassius auratus) has also been introduced to many ponds and lakes in North America, either deliberately as an ornamental fish, or more-or-less accidentally when unwanted pet goldfish were released into nearby ponds, or just flushed down a toilet. Like the common carp, alien populations of goldfish cause important ecological damage in many of the places where they have become well established. 

In 1978, he Amoco Cadiz was wrecked in the same general area as the Torrey Canyon. Considerable ecological damage was also caused by this accident. However, the damage was less intense than that caused by the Torrey Canyon because less-toxic detergents and dispersants were used during the cleanup, in much smaller quantities, and only in high-value places such as harbors. 

We are convinced that these limits do not hold in due consideration the potential ecological damage and the possible human health hazards associated with the presence of asbestos in effluents. In addition it appears that the use of parameters related to the...
