Aesthetic effects

A new facihty should be located ia an area that is economically suitable (see Plant location). At the same time, the social, environmental, and aesthetic effects must be considered. These decisions are part of land-use pohcies. As of this writing (1996), there is no national land-use program. However, there are certain laws that cover portions of this decision-making process and some states have such programs. 

A National Secondary Drinking Water Regulation (NSDWR or secondary standard) is a non-enforceable guideline regarding contaminants that may cause cosmetic effects (such as skin or tooth discoloration) or aesthetic effects (such as taste, odor, or color) in drinking water. EPA recommends secondary standards to water systems but does not require systems to comply. However, states may choose to adopt them as enforceable standards. This information focuses on national primary standards.

Sulfonated azo dyes are widely used in different industries [16]. Some structure of sulfonated and unsulfonated azo dyes is shown in Fig. 1. These water-soluble azo dyes will enter the environment generally with wastewater discharge. Also, these sulfonated and unsulfonated azo dyes have a negative aesthetic effect on the wastewater, and some of these compounds and biodegraded products are also toxic, carcinogenic, and mutagenic [17]. There exists clear evidence that sulfonated azo dyes show decreased or no mutagenic effect compared to unsulfonated azo dyes... 

Secondary NAAQS are set to protect public welfare. This includes economic losses due to damage to agricultural crops, forests, and materials as well as aesthetic effects, including visibility degradation.

National Secondary Drinking Water Regulations (secondary standard) are nonenforceable criteria/ guidelines. They are set at levels that protect against aesthetic effects (e.g., taste, odor, or color) and/or cosmetic effects (e.g., teeth and skin discoloration). Secondary standards are not enforceable under the federal SDWA, however, states can adopt them as enforceable standards. 

Food additives are chemical substances, other than basic foods, used in commercial food preparation to achieve preservative, flavor, color, stability, and aesthetic effects. Though some of the chemicals used are derived naturally, most of the additives used in food production are synthetic and with little or no nutritional value.i22>23] A glance at almost any cookbook shows that chemical additives are not necessary for food preparation. Their use allows inferior ingredients to be used, extends the shelf lives of many products, and exposes people to toxic chemicals. 

In addition to this major use to improve mechanical properties, high aspect ratio flake-type fillers have been added to polymers for a variety of other purposes. They include improved thermal stability (3), high voltage resistance (4), electrical conductivity, radiation shielding (5) and optical and aesthetic effects (6).

By reducing the amount and severity of superficial damages, polishing may also increase the performance of mechanical components. Historically, however, the process was originally conceived for the fabrication of optical elements as well as obtaining aesthetic effects. 

Champaign, IL. A patron entered a restaurant from the bright sunlight for a noon lunch appointment. The restaurant lighting was dim to create an aesthetic effect. There was a two-step change between the small lobby and the seating area. The patron fell down the steps that were only a few feet from the entrance. The patron claimed he was unable to see the steps. 

Air pollution is the release into the atmosphere of various gases, finely divided solids, or finely dispersed liquid aerosols at rates that exceed the natural capacity of the environment to dissipate and dilute or absorb them. These substances may reach concentrations in the air that cause undesirable health, economic or aesthetic effects. 

The NSDWRs are neither mandatory nor enforceable. The 15 contaminants on the list may have cosmetic effects (discoloration of the skin or teeth) or aesthetic effects (color, taste, or odor).
