Eutrophication may only be made available again during autumn turn-over or in conditions of turbulent flow. Enhanced growth of aquatic vegetation or phytoplankton and algal blooms disrupts normal functioning of the ecosystem, causing a variety of problems such as a lack of oxygen needed for fish and shellfish to survive. The water becomes cloudy, typically coloured a shade of green, yellow, brown, or red. Eutrophication also decreases the value of rivers, lakes and aesthetic enjoyment. Health problems can occur where eutrophic conditions interfere with drinking water treatment. Human activities can accelerate the rate at which nutrients enter ecosystems. Runoff from agriculture
Artificial nails fitted properly, artificial nails are usually not problematic. However, long term use and poorly fitted nails can seriously damage the nail bed and hamper natural nail growth. The most common problem associated with artificial nails is a fungal infection that may develop between the false and natural nail. When artificial nails are applied to the natural nail surface, minor types of trauma to the artificial nails which can happen from something as harmless as scraping a nail against a firm surface can cause separation of the nail from its nail bed. This allows bacteria and fungus to potentially enter the
