Tilling only in-row areas (grow zones) and leaving the alleyways untilled and covered with sod or cover crops is an alternative hybrid system that can be used in more challenging circumstances such as compacted soils and cold short-season climates. Depending on the site-specific situation, in-row tilled areas can be either covered with pre-plant plastic mulch or post-plant organic mulch, or left uncovered as strip-till or ridge-till (raised-bed) systems (El Titi 2003).

In the Philippines, about 69% of the total 15,000 industrial firms are located in Metro Manila. These include industries such as textile mills, chemical factories, paper mills, distilleries, food manufacturing plants, plastic plants, soap and detergent factories and tanneries. As a result, four major river systems—the Pasig, Tullahan-Tenejeros, San Juan and Paranaque-Zapote Rivers—are now biologically dead. The same problems exist in various riverine systems in other parts of the country. 

Plastic pellets comprised more than 50% of the man-made debris collected at one Philadelphia, Pennsylvania, storm-water discharge. Pellets were also found in samples collected from four sewage treatment plants. Plastic pellet sources were not identified in research studies, but it is likely that they come from storm runoff (Plastic Pellets in the Aquatic Environment 1992).

The catecholase activity also has important applications, since this activity can be used in the analysis of phenols and its derivatives. Phenolic pollutants are frequently found in surface waters and in the effluent of industrial discharge sources. Some of the industrial sources of phenol discharge include oil refineries, coke and coal conversion plants, plastics and petrochemical companies, dyes, textiles, timber, mining, and the pulp and paper industries. Virtually all phenols are toxic. Moreover, they have a high oxygen demand and can deplete...
