The survey was carried out in 2010. Water samples were collected from two different sites covering the middle of the lake and were analyzed for a pre-defined set of physical and chemical indicators to allow the build up of a meaningful database that can be used for comparative assessment and trend delineation. The results have shown a generally good water quality but have also shown the presence of minor traces of pesticides and heavy metals. The obtained data was classified according to Order 161/2006 into five quality classes, and the classification of the lake was established by using the percentile system V (90%).

In some cases a more localized but sometimes intense cluster of impacts originate from local activities-economic exploitation and tourism. Protected mountain areas are subjected to various pressures ranging from illegal resources exploitation to pressures generated by touristic activities. Glacial mountain lakes are exposed to local and long-range originated environmental pressures and due to their high vulnerability and susceptibility to changes, and can act as environmental sensors recording and forecasting any adverse impact created by natural and/or anthropogenic factors. Environmental impacts were comparatively assessed in three areas in the Carpathian Mountains, mountain areas characterized and influenced by the presence of mountain lakes: Rodnei Mountains (BuhAƒiescu and Iezerul Pietrosului lakes), FAƒgAƒraE™ Mount...

Although the water fluxes are relatively high, glacial mountain lakes represent sensitive areas to human induced disturbances such as atmospheric transported pollutants and pollution generated on site, usually by tourist fluxes. These anthropic inputs can influence water quality and aquatic ecosystems and decrease the ecosystem services provided by the mountain areas. Due to the generally low content of dissolved substances, mountain lakes are sensitive to minor changes in water chemistry, and periodic sampling can serve as early warning in identifying dangerous trends in environmental quality on larger scales. The survey was carried out in 2011 and 2012. In all the surveys, the lakes were sampled in summer-early autumn in the ice-free period. Water samples were collected from three different sites for each lake covering the entire lake surface and were analyzed for a pre-defined set of physical and chemical indicators. Water pH levels ranged between 7.2 -7.9 and electrical conductivity between 14.2 -101.5 S cm -1 . Heavy metals show low concentration in the analyzed water lakes: zinc (1.41-4.04 μg L −1 ), manganese (0.59-5.02 μg L −1 ), nickel (0.28-1.12 μg L −1 ), copper (1.45-5.29 μg L −1 ), cadmium (0.21-0.4 μg L −1 ) which are below the maximum allowed concentration for first quality class according to Romanian legislation. In contrast, measured lead concentration varied between 1.29-5.54 μg L −1 .The results have shown a generally good water quality, the majority of the lakes can be classified as first quality class excepting Bâlea Lake and Pietrosul Lake with values according the second class, due to a slight increase in lead concentration, attributed to atmospheric transport and deposition for Pietrosu Lake, and in Bâlea Lake case due to road traffic or local unknown sources.

Buila-VânturariŃa National Park (BVNP) is a protected area established in 2004. The park is also a protected area in the European Union, as part of the Network European Ecological Natura 2000 (as Site of Community Interest: ROSCI0015 Buila -VânturariŃa, and Special Protected Area: Cozia-Buila-VânturariŃa ROSPA0025). Buffer zone of the park is a fragile area where economic development of BistriŃa limestone quarry needs to respect the conservation of environmental components. From a legal perspective, the park buffer zone does not allow economic activities which are destructive to the environment. The main constraint remains the overlapping of the southern limit of BVNP and Natura 2000 sites over the operational perimeter of the quarry BistriŃa (area of about 16 ha) and access roads to the top of the quarry. The opening activity in the top of the quarry is important for regional socioeconomic context (chemical industry). An environmental impact assessment was applied for quarry which is placed very close to the park. The problems of current and future constraints need to be carefully identified and quantified in protected areas of Romania, as do the root causes and effects of these constraints.

Because of the need to protect this area, in recent years this has produced the need for a natural reservation. Although each Natural Reservation is different, many important values remain the same. Therefore, there are different reservations with different types of natural protection, like: geological, landscape and a range of biodiversity protections (flora and fauna), pedological and speological protection. Of national importance, Râpa Roşie is located near Sebeş, in the centre of Romania. It exhibits spectacular forms of natural soil erosion of the Secaşelor plateau, an area measuring over 25 ha ( , ). The reservation is home to many rare plant species, such as Cotoneaster integerrimus, Centaurea atropurpurea, Dianthus serotinus, Cephalaria radiata and Asplenium adiantum-nigrum. Although founded as a National Reservation decades ago, it was only recently proposed as a Natural 2000 site.

Remote mountain lakes represent a small percentage of this total surface. Due to their geographical location, being situated away from localities and transport routes, as well as because of special protection measures specific for protected areas, remote mountain lakes appeared to be far from human influence, and they must be studied to establish reference conditions, accordingly to Water Framework Directive, for the lowland, more polluted lakes, or to examine ecological processes in areas sheltered by the effects of the direct anthropogenic disturbances, such as local pollution or land use change.
