Recreation resources

Air Quality Related Value (AQRV) a resource, as identified by the ELM for one or more Federal areas, that may be adversely affected by a change in air quality. The resource may include visibility or a specific scenic, cultural, physical, biological, ecological, or recreational resource identified by the ELM for a particular area. "These values include visibility and those scenic, cultural, biological, and recreation resources of an area that are affected by air quality" (43 Fed. Reg. 15016). 

The economic significance of the Black Sea region is determined, first of all, by its transport and pipeline potentialities and recreation resources. Fishery is also retained in the region s economy, although, under the present-day conditions, its significance has strongly decreased. The role of hydrocarbon resources, to date, has been restricted to oil and gas prospecting in the shelf areas of the sea. 

The littoral areas of the Black and Azov Seas with their warm climate are of great socioeconomic significance for intensive development of recreation resources. The natural, ethnic, cultural, historical, and other features of the Black Sea area attract many people for rest and tourism. In the Black Sea there are no predatory and noxious sea animals and there is no tidal activity. One can admire vast expanses of sand beaches and wonderful mountain and forest coastal landscapes, and these regions are not far from European countries. 

The North American Great Lakes are a major ecological, industrial, and recreational resource. It turns out that the average lead concentration in the air over Lake Erie is 11 ng/m3, and the annual flow of lead from the atmosphere into this lake is 21,000 kg/year. Given that the area of Lake Erie is 25,700 km2, please find the deposition velocity for lead into this lake.

The Columbia River s Importance as a recreational resource and a regional source of drinking and Irrigation water, as well as a productive habitat for waterfowl, economically important fish species, and transitory endangered and threatened wildlife, could merit special concern for this environment during implementation of the remedial activities at the 100-N Area. If critical bald eagle habitats exist on the Site, they may be regarded as sensitive environments as defined in Appendix A of 40 CFR Part 300. 

Miller and colleagues (15) surveyed 17 of the first adult ventilator users in the United States with neuromuscular conditions regarding their health, education, work, recreation, resources, and hfe satisfaction pre- and post-ventilation. The majority (11 of 17) indicated that their quality of life had declined over time and listed decreased mohihty, increased dependence, decreased community access, and decreased activity as factors.

The available water resources are linked to human health in several ways water for drinking, hygiene, recreational activities and food production. As water resources decrease as a consequence of droughts or increased demand, the need to use water sources of poor quality appears, and consequently the risk of an increase in the occurrence of outbreaks of infectious diseases related to water can be higher. 

From the human perspective, HABs are problematic because they cause (1) risks to human health, (2) loss of natural or cultured seafood resources, (3) impairment of tourism and recreational activities, and (4) damage to noncommercial marine resources and wildlife. Exposure pathways include (1) consumption of toxic shellfish that have accumulated phytoplankton toxins filtered from the water, (2) consumption of tropical fish that have accumulated phytoplankton toxins (ciguatera), (3) inhalation of aerosolized toxins ejected from the sea surface, and (4) skin contact resulting in irritations due to allergy-like reactions. Harmful health effects from acute exposures have been relatively well studied. Less well known are the health effects resulting from chronic exposures to low toxin levels. This is of particular concern with regards to marine mammals and seabirds. 

Mountains are the water towers of the world. However, they are not only an important source of water but also a source of key resources such as energy, minerals, and forest and agricultural products. They offer a multitude of recreational opportunities, and probably most importantly, serve as storehouses for biological diversity. Mountains provide the living space for about 10% of the world s population. A much larger percentage of the population profits from the various services of mountains, most of which depend on water. 

Marine fish and shellfish constitute a valuable renewable resource that, with proper management, can contribute significantly to the nation s economic growth. The nation s marine resources support both recreational and commercial fishing and are managed to reflect both. 

The Magnuson Fishery Conservation and Management Act (MFCMA) of 1976, as amended, is the most significant fisheries legislation in the nation s 200-year history. It provides for the conservation and exclusive management by the U.S. of all fishery resource within the Fishery Conservation Zone or FCZ which extends 200 nautical miles from our shores. The land area equivalent to the U.S. FCZ is approximately 3.6 million square miles. It has afforded an unprecedented opportunity for U.S. commercial and recreational fishermen to reach new levels of production and to expand further their already significant contributions to the nation s food supply and economy. 

The NMFS role in fisheries development is catalytic in nature by encouraging and assisting in the achievement of full utilization of U.S. fishery resources to derive maximum economic and social benefits from those resources under U.S. jurisdiction. In practical terms, this will require greater initiative on the part of the commercial and recreational fishing industries to utilize America s non-traditional fish species, while the Federal Government will work to reduce foreign fishing in our fishery conservation zone and remove or reduce other impediments. 

Human activities harmfully influence the environment and nature in many ways. The production of undesirable wastewater, waste gas, and liquid plus solid residues seems to be inevitable during chemical processes. The public is more sensitive to pollution of the aquatic environment and the depletion of clean water resources, because they have an immediate impact on daily routine and recreational activities. However, air pollution has an adverse impact on our health in the short and long term, and the problems of the greenhouse effect and the destruction of stratospheric ozone could extinguish life from the face of the Earth. These problems are enhanced by overpopulation and urbanization. Today, urban areas can be seen as monsters that consume large amounts of energy, matter, and freshwater and release all kinds of waste into the environment. 

Protection Agency s priority pollutant list (Cerniglia, 1992). The environmental persistence and genotoxicity of PAHs increases as the molecular size increases up to four or five fused benzene rings, and toxicological concern shifts to chronic toxicity, primarily carcinogenesis (Miller Miller, 1981). In short, oil pollution on land and in the sea presents a serious problem to public health, commercial fisheries, land development, and recreational and water resources. 

Our forests are limited resources, valuable for recreation, soil and water management, and timber. Thus, control of various forest pests is receiving increased attention. 

Within the past half century, and more so in the last two decades, we have realized that our forests are limited resources. Their value not only for timber, but for recreation and soil and water management has been recognized. With this came the realization of the need to manage the resource for the benefit of man and the environment.
