Detailed explanation-1: -Wetlands take up metals both by adsorption in the soils and by plant uptake via the roots. They allow metabolism of oxygen-demanding materials and can reduce fecal coliform populations. These pollutants are often buried by deposition of newer plant material, isolating them in the sediments.

Detailed explanation-2: -Wetlands, or simply a wetland, is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils.

Detailed explanation-3: -In New Jersey and throughout the United States, wetlands are protected on public and private property. New Jersey protects wetlands under the New Jersey Freshwater Wetlands Protection Act. This law also protects transition areas or “buffers” around freshwater wetlands.

Detailed explanation-4: -New Jersey’s wetlands consist largely of emergent estuarine wetlands (salt, brackish, slightly braskish and oligohaline), intertidal flats, and lacustrine wetlands associated with lakes and reservoirs.
